Description

携帯装置、携帯装置の制御方法、及び制御プログラムPortable device, method for controlling portable device, and control program
　本発明は、携帯装置、携帯装置の制御方法、及び制御プログラムに関する。 The present invention relates to a mobile device, a control method for the mobile device, and a control program.
　携帯端末の多機能化につれて、携帯端末内には通信用のＣＰＵの他に、アプリケーション用のＣＰＵが実装されている。２つのＣＰＵを搭載すると消費電力も増大する。そこで電力消費量を低減するために、画面表示の更新間隔に基づいてアプリケーションＣＰＵへの電力供給を増減する構成が知られている（たとえば、特許文献１参照）。 As mobile terminals become more multifunctional, CPUs for applications are mounted in the mobile terminals in addition to CPUs for communication. When two CPUs are installed, power consumption increases. In order to reduce power consumption, a configuration is known in which the power supply to the application CPU is increased or decreased based on the screen display update interval (see, for example, Patent Document 1).
　他方、複数の異なる情報通信機器間で表示装置を共有するシステムが知られている。たとえば、１つの表示装置に、コンピュータ本体と、テレビジョンセットやビデオレコーダなどの外部機器を接続する。表示装置は、コンピュータ用のモニタ画面として使用されるととともに、テレビジョンやビデオプレーヤからの映像の表示画面として使用される。画面の切り替えは、一般にユーザによる切り替え操作によって行なわれる。画面切り替えの利便性と省電力性を高めるため、コンピュータ画面表示中の表示切り替え操作に応じて、表示装置が自動的にスタンドバイコマンドを生成してコンピュータ本体に送信する構成が提案されている（たとえば、特許文献２参照）。 On the other hand, a system for sharing a display device between a plurality of different information communication devices is known. For example, a computer main body and an external device such as a television set or a video recorder are connected to one display device. The display device is used as a monitor screen for a computer and also as a display screen for video from a television or a video player. Switching between screens is generally performed by a switching operation by a user. In order to improve the convenience and power saving of screen switching, a configuration has been proposed in which a display device automatically generates a standby command and transmits it to a computer body in response to a display switching operation during computer screen display ( For example, see Patent Document 2).

　１つの携帯装置内に異なる複数のシステムを内蔵する場合、表示手段を複数のシステム間で共有させることによって、装置の小型化を図ることができる。しかし、これを実現するためには、システム間での表示手段の切り替え制御が必要になる。また、発熱による装置の温度上昇や、消費電力量を低減する機能が必要になる。 When a plurality of different systems are built in one portable device, the size of the device can be reduced by sharing the display means between the plurality of systems. However, in order to realize this, it is necessary to control switching of display means between systems. In addition, a function to reduce the temperature rise of the device due to heat generation and the power consumption is required.
　たとえば、携帯装置に、パーソナルコンピュータ（ＰＣ）システムと携帯（セルラ）システムを搭載した場合、ＰＣ機能の使用中に電子メールや音声通話の着信があることが想定される。この場合、携帯システムを優先して表示画面を携帯システム側に切り替えることが考えられる。表示画面の切り替えにより、ＰＣの画像は携帯装置の表示スクリーンには表示されないことになるが、ＰＣの機能は出力されたままになる。そのため、電力の無駄やＰＣ部の発熱、不要動作によるＰＣ部からのノイズ（電波放射）発生という問題が生じる。 For example, when a personal computer (PC) system and a portable (cellular) system are installed in a portable device, it is assumed that an incoming e-mail or voice call is received while using the PC function. In this case, it is conceivable to switch the display screen to the mobile system side with priority on the mobile system. By switching the display screen, the PC image is not displayed on the display screen of the portable device, but the PC function remains output. For this reason, problems such as waste of electric power, heat generation of the PC unit, and generation of noise (radio wave radiation) from the PC unit due to unnecessary operations occur.
　そこで、異なるシステムが内蔵された携帯装置でシステムが切り替えられたときに、電力増大、発熱、ノイズの発生を防止しつつ、システム間の切り替えを円滑に行なうことのできる携帯装置と制御方法の提供を課題とする。 Therefore, a portable device and a control method that can smoothly switch between systems while preventing power increase, heat generation, and noise generation when the system is switched between portable devices incorporating different systems. Is an issue.

　本発明の具体的な実施の形態を、添付の図面を参照して説明する。実施例では、２つの異なるシステムを内蔵した携帯装置として、コンピュータシステム（ＰＣ機能）と、携帯システムを内蔵する携帯装置１を例にとって説明する。 Specific embodiments of the present invention will be described with reference to the accompanying drawings. In the embodiment, as a portable device incorporating two different systems, a computer system (PC function) and a portable device 1 incorporating a portable system will be described as examples.
　図１及び図２は、携帯装置１の外観図である。図１は、キーボード操作面６を開いた状態での外観を示し、図２は、キーボード操作面６を閉じた状態での６面図である。携帯装置１は、表示スクリーン４を有する第１の筐体２と、キーボード操作面６を有する第２の筐体３を含む。キーボード操作面６を閉じた状態では、図２中央の上面図に示すように、キーボード操作面６は第１の筐体２により隠蔽され、表示スクリーン４が外側に向いている。 1 and 2 are external views of the portable device 1. FIG. 1 shows an external appearance with the keyboard operation surface 6 opened, and FIG. 2 is a six-view diagram with the keyboard operation surface 6 closed. The portable device 1 includes a first housing 2 having a display screen 4 and a second housing 3 having a keyboard operation surface 6. When the keyboard operation surface 6 is closed, the keyboard operation surface 6 is concealed by the first housing 2 and the display screen 4 faces outward as shown in the top view in the center of FIG.
　一例として、表示スクリーン４側の第１の筐体２に、携帯（セルラ）システム用の回路（携帯回路）と、システム切り替え回路を配置し、キーボード操作面６側の第２の筐体３に、コンピュータシステム用の回路（ＰＣ回路）を配置する。本実施例は、コンピュータシステムとしてパーソナルコンピュータ（以下、適宜「ＰＣ」と略称する）を例示する。もっとも、各システムおよびコンピュータシステムの種類は、この例に限定されるわけではない。 As an example, a circuit (mobile circuit) for a portable (cellular) system and a system switching circuit are arranged in the first casing 2 on the display screen 4 side, and the second casing 3 on the keyboard operation surface 6 side is arranged. A circuit (PC circuit) for a computer system is arranged. The present embodiment exemplifies a personal computer (hereinafter abbreviated as “PC” as appropriate) as a computer system. However, the type of each system and computer system is not limited to this example.
　携帯回路を内蔵する第１の筐体２の側面には、システム切り替えスイッチ５が設けられている。ユーザは、システム切り替えスイッチ５を操作することによって、ＰＣ機能と携帯機能をマニュアルで切り替えることができる。なお、以下において、携帯装置１でＰＣ機能が使用されている状態をＰＣモード、携帯装置１で携帯機能が使用されている状態を携帯モードとも呼ぶ。携帯装置１では、システム切り替えスイッチ５の操作によるシステムの選択が優先される。システム切り替えスイッチの操作がない場合であって、ＰＣと携帯システムの動作が競合する場合、たとえば、ＰＣの使用中に携帯システムに音声またはデータの着信があった場合などは、携帯システムが優先される。 A system changeover switch 5 is provided on the side surface of the first housing 2 containing the portable circuit. The user can manually switch between the PC function and the portable function by operating the system switch 5. Hereinafter, a state in which the PC function is used in the portable device 1 is also referred to as a PC mode, and a state in which the portable function is used in the portable device 1 is also referred to as a portable mode. In the portable device 1, selection of a system by operating the system changeover switch 5 has priority. If there is no operation of the system changeover switch and the operation of the PC and the mobile system competes, for example, if the mobile system receives voice or data while using the PC, the mobile system has priority. The
　たとえば、ユーザが携帯装置１をＰＣとして使用している場合、表示スクリーン４には、入力作業に応じた画像が表示される。ここで、携帯装置１の携帯回路に着信があった場合、表示画面の切り替えが行われる。後述するように、実施例では、携帯回路が表示出力の切り替え制御を行う。ＰＣは、自身の画像信号が表示スクリーン４に出力されているかどうか判別できないため、自ら省電力状態に入ることができない。このことは、ユーザがシステム切り替えスイッチ５を操作して携帯装置１を携帯モードに移行した場合でも同様である。 For example, when the user uses the mobile device 1 as a PC, an image corresponding to the input work is displayed on the display screen 4. Here, when there is an incoming call to the mobile circuit of the mobile device 1, the display screen is switched. As will be described later, in the embodiment, the portable circuit performs display output switching control. Since the PC cannot determine whether or not its own image signal is output to the display screen 4, it cannot enter the power saving state. This is the same even when the user operates the system switch 5 to shift the portable device 1 to the portable mode.
　そこで、実施例では、ＰＣ回路から携帯回路への切り替えが行われた場合に、携帯回路は、ＰＣ回路に対する省電力制御に先立って、ＰＣを省電力モードへの移行準備状態にする。具体的には、以下で詳述するように、入力装置を携帯回路側のみに接続しておき、ＰＣ使用時には、携帯回路が仮想入力デバイスとしてＰＣ回路に対する入力装置として動作する。この場合、携帯回路は入力装置に対する入力を受け、その入力に応じた信号をＰＣ回路側に送信する。ＰＣモードから携帯モードへのシステム切り替えの必要性が生じたときに、携帯回路は、例えば仮想入力デバイスとしての動作を停止するなどして、入力装置をＰＣ回路側から切り離す。これによりＰＣへの外部からの入力を遮断し、入力装置に対する入力操作に伴うＰＣ回路の動作変動を抑止することでＰＣ回路の動作を安定させる。その結果、ＰＣ部の動作に伴う電力増加や発熱、不要動作によるノイズ発生を抑制することができる。 Therefore, in the embodiment, when switching from the PC circuit to the portable circuit is performed, the portable circuit puts the PC in a preparation state for shifting to the power saving mode prior to the power saving control for the PC circuit. Specifically, as described in detail below, the input device is connected only to the portable circuit side, and when the PC is used, the portable circuit operates as a virtual input device as an input device for the PC circuit. In this case, the portable circuit receives an input to the input device and transmits a signal corresponding to the input to the PC circuit side. When there is a need to switch the system from the PC mode to the portable mode, the portable circuit disconnects the input device from the PC circuit side, for example, by stopping the operation as a virtual input device. As a result, the external input to the PC is blocked, and the operation of the PC circuit is stabilized by suppressing the fluctuation of the operation of the PC circuit due to the input operation to the input device. As a result, it is possible to suppress an increase in power, heat generation, and noise caused by unnecessary operations due to the operation of the PC unit.
　図３は、携帯装置１のハードウエア構成図、図４は、携帯装置１の機能ブロック図である。図３において、携帯装置１は、携帯システム１０、ＰＣシステム２０、表示部（ＬＣＤ）３０、及び入力部４０を含む。本実施例は、表示部３０としてＬＣＤを例示する。しかしながら、表示部３０はそれに限定されるものではなく、他種の表示デバイスであってもよい。表示部（ＬＣＤ）３０は、携帯システム１０とＰＣシステム２０のそれぞれに接続されているが、表示部（ＬＣＤ）３０への映像（画像）信号入力の切り替えは、携帯システム１０によって行なわれる。入力部４０は、携帯システム１０に接続されている。 FIG. 3 is a hardware configuration diagram of the mobile device 1, and FIG. 4 is a functional block diagram of the mobile device 1. In FIG. 3, the mobile device 1 includes a mobile system 10, a PC system 20, a display unit (LCD) 30, and an input unit 40. In this embodiment, an LCD is exemplified as the display unit 30. However, the display unit 30 is not limited thereto, and may be another type of display device. The display unit (LCD) 30 is connected to each of the mobile system 10 and the PC system 20, but switching of video (image) signal input to the display unit (LCD) 30 is performed by the mobile system 10. The input unit 40 is connected to the mobile system 10.
　携帯システム１０は、携帯アプリケーションプロセッサ３７、通信用プロセッサ３９、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）３８、ＵＳＢ（Ｕｎｉｖｅｒｓａｌ　Ｓｅｒｉａｌ　Ｂｕｓ）インタフェース３６、オーディオ部５６を含み、これらはバスによってデータ通信可能に相互に接続されている。携帯アプリケーションプロセッサ３７は、着信メロディ作成、携帯ゲームなどの携帯アプリケーションの処理のほか、後述するように、表示部３０への画像信号の切り替え、ＰＣシステム２０に対する入力部４０の仮想的な接続・切り離し、ＰＣシステム２０に対する省電力制御などを行う。 The portable system 10 includes a portable application processor 37, a communication processor 39, a RAM (Random Access Memory) 38, a USB (Universal Serial Bus) interface 36, and an audio unit 56, which are connected to each other via a bus so that data communication is possible. ing. The portable application processor 37 performs processing of portable applications such as ringing melody creation and portable games, as well as switching of image signals to the display unit 30 and virtual connection / disconnection of the input unit 40 to the PC system 20 as will be described later. Then, power saving control for the PC system 20 is performed.
　通信用プロセッサ３９は、通信プロトコルの処理やデータ信号の処理を行なう。携帯システム１０への音声着呼や電子メールの受信があった場合、通信用プロセッサ３９は携帯アプリケーションプロセッサ３７に着信を通知する。ＲＡＭ３８は、携帯アプリケーションプロセッサ３７や通信用プロセッサ３９による処理においてデータを一時格納するためのワークエリアを提供する。オーディオ部５６は、音響信号や音声を処理して出力する。 The communication processor 39 performs communication protocol processing and data signal processing. When a voice call or electronic mail is received to the portable system 10, the communication processor 39 notifies the portable application processor 37 of the incoming call. The RAM 38 provides a work area for temporarily storing data in processing by the portable application processor 37 and the communication processor 39. The audio unit 56 processes and outputs an acoustic signal and sound.
　携帯システム１０は、携帯装置１に内蔵される第１のシステムの一例であり、携帯アプリケーションプロセッサ３７が、第１処理回路の一例である。 The mobile system 10 is an example of a first system built in the mobile device 1, and the mobile application processor 37 is an example of a first processing circuit.
　入力部４０は、たとえば、キーボード４１、トラックボール４２、タッチパネル４３、カメラ４４、ＧＰＳ（Ｇｌｏｂａｌ　Ｐｏｓｉｔｉｏｎｉｎｇ　Ｓｙｓｔｅｍ）４５、ＳＤ（Ｓｅｃｕｒｅ　Ｄｉｇｉｔａｌ）メモリカードスロット４６等を含む。入力部４０に含まれる各デバイス４１－４６は、携帯システム１０の携帯アプリケーションプロセッサ３７に接続されている。入力部４０の各デバイス４１－４６のサービスは、携帯システム１０のＵＳＢインタフェース３６を通して入力部４０を仮想化することによって、ＰＣシステム２０側へ提供される。なお、入力部４０は、例示した上述のデバイスに限定されるものではなく、それらのうちの一部のデバイスであってもよいし、上述デバイスとは種類が異なる他のデバイスであってもよい。 The input unit 40 includes, for example, a keyboard 41, a trackball 42, a touch panel 43, a camera 44, a GPS (Global Positioning System) 45, an SD (Secure Digital) memory card slot 46, and the like. Each device 41-46 included in the input unit 40 is connected to the portable application processor 37 of the portable system 10. The services of the devices 41 to 46 of the input unit 40 are provided to the PC system 20 side by virtualizing the input unit 40 through the USB interface 36 of the portable system 10. Note that the input unit 40 is not limited to the above-described devices illustrated, and may be a part of the devices, or may be another device having a different type from the above-described devices. .
　ＰＣシステム２０は、ＷＬＡＮ（Ｗｉｒｅｌｅｓｓ　ＬＡＮ）回路６１、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）６２、ディスクドライブ６３、ＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）６４、電源回路６５、ＳＰＩ（Ｓｅｒｉａｌ　Ｐｅｒｉｐｈｅｒａｌ　Ｉｎｔｅｒｆａｃｅ）インタフェース６７、グラフィックコントローラ６８を含み、これらはバスによりデータ通信可能に相互に接続されている。ＷＬＡＮ回路６１はＰＣカードであってもよいし、アンプと一体化された回路であってもよい。ＲＡＭ６２は、主記憶装置としてＣＰＵ６４が実行するプログラムやデータの一時格納のためのワークエリアを提供する。ディスクドライブ６３は、補助記憶装置として各種メディアの読み書きを駆動する。ＣＰＵ６４は各デバイスの制御やデータの計算、加工を行う。 The PC system 20 includes a WLAN (Wireless LAN) circuit 61, a RAM (Random Access Memory) 62, a disk drive 63, a CPU (Central Processing Unit) 64, a power supply circuit 65, an SPI (Serial Peripheral Interface) interface 67, and a graphic controller 68. These are connected to each other via a bus so that data communication is possible. The WLAN circuit 61 may be a PC card or a circuit integrated with an amplifier. The RAM 62 provides a work area for temporarily storing programs and data executed by the CPU 64 as a main storage device. The disk drive 63 drives reading / writing of various media as an auxiliary storage device. The CPU 64 controls each device and calculates and processes data.
　電源回路６５は、ＰＣシステム２０の各動作に必要な電力を生成する。電源回路６５は、携帯システム１０側の携帯アプリケーションプロセッサ３７に接続され、携帯アプリケーションプロセッサ３７から電源制御信号５０を受け取る。この電源制御信号５０に基づいて、ＰＣシステム２０電源回路６５はスタンバイ状態やその他の状態に移行し、必要に応じて省電力状態に移行することができる。 The power supply circuit 65 generates electric power necessary for each operation of the PC system 20. The power supply circuit 65 is connected to the portable application processor 37 on the portable system 10 side and receives the power supply control signal 50 from the portable application processor 37. Based on the power control signal 50, the PC system 20 power circuit 65 can shift to a standby state or other states, and can shift to a power saving state as necessary.
　ＵＳＢ（Ｕｎｉｖｅｒｓａｌ　Ｓｅｒｉａｌ　Ｂｕｓ）インタフェース６６は、携帯アプリケーションプロセッサ３７のＵＳＢインタフェース３６を通して、入力部４０を仮想化してＰＣシステム２０側へ接続する。入力部４０は、ＰＣシステム２０と直接接続されていないが、ＰＣシステム２０からみると、作業時に入力部４０と接続するためのＵＳＢインタフェース３５およびアプリケーションプロセッサ３７を介して入力部４０が直接接続されているものとして認識される。後述するように、ＰＣシステム２０の使用中に携帯システム１０に着信があった場合、あるいはユーザがシステム切り替えスイッチ５を操作した場合は、アプリケーションプロセッサ３７によってＵＳＢインタフェース３５が切り離される。ＰＣシステム２０は、ＵＳＢインタフェース３５の切り離しを認識するわけではないが、アプリケーションプロセッサ３７がＰＣシステム２０側への入力デバイス４１－４６のサービスの提供を遮断することにより、以後はＰＣシステム２０への入力が行なわれない。これにより、ＰＣシステム２０の動作が安定し、ＰＣシステム２０での発熱、不要操作によるノイズ発生、消費電力の増大が防止される。 A USB (Universal Serial Bus) interface 66 virtualizes the input unit 40 through the USB interface 36 of the portable application processor 37 and connects it to the PC system 20 side. The input unit 40 is not directly connected to the PC system 20, but when viewed from the PC system 20, the input unit 40 is directly connected via the USB interface 35 and the application processor 37 for connecting to the input unit 40 during work. Is recognized as being. As will be described later, when the mobile system 10 receives an incoming call while the PC system 20 is being used, or when the user operates the system selector switch 5, the USB interface 35 is disconnected by the application processor 37. Although the PC system 20 does not recognize the disconnection of the USB interface 35, the application processor 37 blocks the provision of the service of the input devices 41-46 to the PC system 20, so that the PC system 20 is connected to the PC system 20 thereafter. No input is made. Thereby, the operation of the PC system 20 is stabilized, and heat generation in the PC system 20, generation of noise due to unnecessary operations, and increase in power consumption are prevented.
　ＳＰＩインタフェース６７は、携帯アプリケーションプロセッサ３７との間で、信号線５５を介したシリアル伝送により制御信号を送受信する。たとえば、ＰＣシステム２０による映像信号は、グラフィックコントローラ６８から信号線３３によりＬＣＤ３０に出力されるが、その表示制御は、ＳＰＩインタフェース６７と信号線５５を介して、携帯システム１０側のアプリケーションプロセッサ３７経由で行なわれる。 The SPI interface 67 transmits and receives control signals to and from the portable application processor 37 by serial transmission via the signal line 55. For example, the video signal from the PC system 20 is output from the graphic controller 68 to the LCD 30 via the signal line 33, and the display control is performed via the application interface 37 on the portable system 10 side via the SPI interface 67 and the signal line 55. Is done.
　グラフィックコントローラ６８は、信号線３３によって表示部（ＬＣＤ）３０に接続される。ＰＣシステム２０の映像信号は、グラフィックコントローラ６８から信号線３３を介してＬＣＤ３０に出力される。グラフィックコントローラ６８は、第２のシステムであるＰＣシステム２０側の第２処理回路に対応する。 The graphic controller 68 is connected to the display unit (LCD) 30 by the signal line 33. The video signal of the PC system 20 is output from the graphic controller 68 to the LCD 30 via the signal line 33. The graphic controller 68 corresponds to a second processing circuit on the PC system 20 side that is the second system.
　携帯システム１０側の映像信号は、アプリケーションプロセッサ３７から出力され、信号線３４を介してＬＣＤ３０に出力される。ＬＣＤ３０は、携帯システム１０とＰＣシステム２０によって共有され、双方から映像信号を受け取る。しかし、いずれの映像信号を入力信号とするかは、アプリケーションプロセッサ３７が出力する映像切り替え制御信号５１に基づいて決定される。 The video signal on the mobile system 10 side is output from the application processor 37 and output to the LCD 30 via the signal line 34. The LCD 30 is shared by the portable system 10 and the PC system 20 and receives video signals from both. However, which video signal is used as the input signal is determined based on the video switching control signal 51 output from the application processor 37.
　このようなハードウエア構成に基づき、図４の機能ブロック図を参照して、さらに制御処理について説明する。携帯アプリケーションプロセッサ３７の表示・電力制御部１４は表示部３０の画面表示を制御する制御信号Ａ（画面表示制御信号）を生成、出力する。制御信号Ａは、表示部３０の制御入力部３１に入力されて、表示部３０の画面設定、バックライト消灯等を制御する。 Based on such a hardware configuration, the control process will be further described with reference to the functional block diagram of FIG. The display / power control unit 14 of the portable application processor 37 generates and outputs a control signal A (screen display control signal) for controlling the screen display of the display unit 30. The control signal A is input to the control input unit 31 of the display unit 30 to control the screen setting of the display unit 30 and the backlight turn-off.
　表示・電力制御部１４はまた、表示部３０に表示する映像信号の切り替えを制御する制御信号Ｂ（映像切り替え信号）を生成し、出力する。制御信号Ｂは、表示部３０の映像信号切り替え部７１に入力される。表示部３０の映像信号切り替え部７１には、携帯アプリケーションプロセッサ３７の映像信号出力部１７から出力される映像信号Ｄと、ＰＣシステム２０の映像信号出力部２３から出力される映像信号Ｅも入力される。ＰＣシステム２０の映像信号出力部２３は、図３のグラフィックコントローラ６８の映像信号生成処理機能に対応する。 The display / power control unit 14 also generates and outputs a control signal B (video switching signal) for controlling switching of the video signal displayed on the display unit 30. The control signal B is input to the video signal switching unit 71 of the display unit 30. The video signal switching unit 71 of the display unit 30 also receives the video signal D output from the video signal output unit 17 of the portable application processor 37 and the video signal E output from the video signal output unit 23 of the PC system 20. The The video signal output unit 23 of the PC system 20 corresponds to the video signal generation processing function of the graphic controller 68 of FIG.
　表示部３０の映像信号切り替え部７１は、携帯アプリケーションプロセッサ３７から入力される制御信号Ｂにしたがって、映像信号Ｅと映像信号Ｄのいずれを入力信号とすべきかを選択する。選択された信号は映像信号Ｆとして表示部３０の映像入力部３２に入力される。 The video signal switching unit 71 of the display unit 30 selects which of the video signal E and the video signal D should be an input signal according to the control signal B input from the portable application processor 37. The selected signal is input as the video signal F to the video input unit 32 of the display unit 30.
　携帯アプリケーションプロセッサ３７の通信インタフェース１６と、ＰＣシステム２０の表示・電源制御部２２の間では、制御信号Ｃが双方向シリアルバス上で送受信される。表示・電源制御部２２は、図３のグラフィックコントローラ６８とＳＰＩインタフェース６７の機能を含む。制御信号Ｃは、ＰＣシステム２０の表示用の制御信号、たとえば、ＰＣ画面のＯＮ／ＯＦＦや輝度を制御するための信号である。この制御信号Ｃは、携帯システム１０の携帯アプリケーションプロセッサ３７経由で、制御信号Ａとして表示部３０に入力される。 Between the communication interface 16 of the portable application processor 37 and the display / power control unit 22 of the PC system 20, a control signal C is transmitted / received on a bidirectional serial bus. The display / power control unit 22 includes the functions of the graphic controller 68 and the SPI interface 67 of FIG. The control signal C is a control signal for display of the PC system 20, for example, a signal for controlling ON / OFF and luminance of the PC screen. The control signal C is input to the display unit 30 as the control signal A via the portable application processor 37 of the portable system 10.
　制御信号Ｃはまた、携帯アプリケーションプロセッサ３７からＰＣシステム２０に対する省電力制御信号としても使用される。省電力制御信号としての制御信号Ｃは、後述するように、ＰＣシステム２０から携帯システム１０へとシステムが切り替えられてから一定時間経過後に生成され、送信されてもよい。 The control signal C is also used as a power saving control signal from the portable application processor 37 to the PC system 20. As will be described later, the control signal C as the power saving control signal may be generated and transmitted after a predetermined time has elapsed since the system was switched from the PC system 20 to the portable system 10.
　携帯アプリケーションプロセッサ３７のＩ／Ｏインタフェース３５Ａと、ＰＣシステム２０のＩ／Ｏインタフェース３５Ｂの間で、制御信号Ｑが伝送される。Ｉ／Ｏインタフェース３５Ａ、３５Ｂは、図３に示すインタフェース３５を構成する。すなわち、入力装置４０の各種入力機能４１－４６は、携帯アプリケーションプロセッサ３７のＩ／Ｏインタフェース１８に接続され、ＰＣシステム２０には直接接続されていない。携帯システム１０の入力機能（キーボード４１、トラックボール４２、タッチパネル４３、カメラ４４、ＧＰＳ４５、ＳＤカードスロット４６など）は携帯アプリケーションプロセッサ３７の動作によって仮想化され、ＰＣシステム２０は、制御信号Ｑを用いてあたかも自システムの入力装置であるかのようにそれらを使用する。 A control signal Q is transmitted between the I / O interface 35A of the portable application processor 37 and the I / O interface 35B of the PC system 20. The I / O interfaces 35A and 35B constitute the interface 35 shown in FIG. That is, the various input functions 41 to 46 of the input device 40 are connected to the I / O interface 18 of the portable application processor 37 and are not directly connected to the PC system 20. The input functions (keyboard 41, trackball 42, touch panel 43, camera 44, GPS 45, SD card slot 46, etc.) of the mobile system 10 are virtualized by the operation of the mobile application processor 37, and the PC system 20 uses the control signal Q. Use them as if they were the input devices of your system.
　ＰＣシステム２０で作業中に、システムを携帯システム１０側に切り替えるイベントが生じた場合、たとえば、携帯システム１０の通信用プロセッサ３９が着信を検出した場合、あるいは、システム切り替えスイッチ５がユーザにより操作されて携帯システム１０側への切り替え要求が入力された場合に、携帯アプリケーションプロセッサ３７は制御信号Ｑを切断する。この結果、ＰＣシステム２０のＩ／Ｏインタフェース３５Ｂに仮想的に接続されていた入力部４０は、ＰＣシステム２０と切り離される。以後の入力操作は、携帯システム１０に対する入力として扱われる。また、上記イベントの発生があると、表示・電力制御部１４は、制御信号Ｂを用いて映像信号切り替え部７１に映像信号の切り替えを指示する。これにより、表示部３０に入力される映像信号は、携帯アプリケーションプロセッサ３７からの映像信号Ｄに切り替えられる。 When an event for switching the system to the mobile system 10 side occurs while working on the PC system 20, for example, when the communication processor 39 of the mobile system 10 detects an incoming call, or the system changeover switch 5 is operated by the user. When the request for switching to the portable system 10 is input, the portable application processor 37 disconnects the control signal Q. As a result, the input unit 40 virtually connected to the I / O interface 35B of the PC system 20 is disconnected from the PC system 20. Subsequent input operations are treated as inputs to the portable system 10. When the event occurs, the display / power control unit 14 instructs the video signal switching unit 71 to switch the video signal using the control signal B. Thereby, the video signal input to the display unit 30 is switched to the video signal D from the portable application processor 37.
　図５は、本発明の一実施例による携帯装置の制御プロセスを示すシーケンス図である。ステップＳ１０１で、携帯装置においてＰＣシステム２０が使用されている。この状態で、携帯システム１０は所定のイベントの発生を検出する（Ｓ１０２）。所定のイベントは、携帯への着信、システム切り替えスイッチ５の操作などである。イベント検出に応じて、携帯システム１０（すなわち携帯アプリケーションプロセッサ３７）は、ＰＣシステム２０の仮想入力デバイス４０の切り離しを行なう（Ｓ１０３）。この処理はＰＣシステム２０からは認識されないが、仮想入力デバイスの切り離しにより、ＰＣシステム２０に対する入力のない状態となる。この状態を、省電力制御への移行準備状態とする。すなわち、明示の省電力制御は行われていないが、ＰＣシステム２０への入力がなくなることで、ＰＣシステム２０の動作変動が抑止されて動作が安定し、ＰＣシステム２０の不要な動作による電波放射や発熱、ノイズ発生が抑制される。 FIG. 5 is a sequence diagram showing a control process of the portable device according to one embodiment of the present invention. In step S101, the PC system 20 is used in the portable device. In this state, the portable system 10 detects the occurrence of a predetermined event (S102). The predetermined event is an incoming call to the mobile phone, an operation of the system switch 5 or the like. In response to the event detection, the mobile system 10 (that is, the mobile application processor 37) disconnects the virtual input device 40 of the PC system 20 (S103). Although this process is not recognized by the PC system 20, there is no input to the PC system 20 by disconnecting the virtual input device. This state is a preparation state for shifting to power saving control. That is, although explicit power saving control is not performed, since there is no input to the PC system 20, fluctuations in the operation of the PC system 20 are suppressed, the operation becomes stable, and radio wave emission due to unnecessary operations of the PC system 20 Heat generation and noise are suppressed.
　携帯アプリケーションプロセッサ３７は、表示部（ＬＣＤ）３０の表示を、ＰＣシステム２０側から携帯システム１０側に切り替える（Ｓ１０４）。ステップＳ１０３の仮想入力デバイスの切り離しと、ステップＳ１０４の表示されるシステム映像の切り替えは、同時に行なわれてもよい。その後、携帯システム１０は、通話、着信の確認、電子メールの送信などの目的で使用される（Ｓ１０５）。携帯システム１０の使用が終わり、ＰＣシステム２０への切り替え要求が入力（すなわち、システム切り替え操作スイッチ５が操作）される（Ｓ１０６）。携帯アプリケーションプロセッサ３７は、インタフェース３５を接続することによって、入力デバイス４０を仮想的にＰＣシステム２０へと接続する（Ｓ１０７）。これにより、ＰＣシステム２０は通常動作に復帰する（Ｓ１０８）。以後、入力デバイス４０はＰＣシステム２０の入力装置であるかのように取り扱われる。 The portable application processor 37 switches the display on the display unit (LCD) 30 from the PC system 20 side to the portable system 10 side (S104). The disconnection of the virtual input device in step S103 and the switching of the system video displayed in step S104 may be performed simultaneously. Thereafter, the portable system 10 is used for purposes such as calling, confirmation of incoming calls, and transmission of e-mail (S105). The use of the portable system 10 ends, and a switching request to the PC system 20 is input (that is, the system switching operation switch 5 is operated) (S106). The portable application processor 37 virtually connects the input device 40 to the PC system 20 by connecting the interface 35 (S107). As a result, the PC system 20 returns to the normal operation (S108). Thereafter, the input device 40 is handled as if it were an input device of the PC system 20.
　図５の方法の利点は、携帯システム１０に切り替えられた後に、比較的短時間のうちに再度ＰＣシステム２０に戻る場合、仮想入力デバイス４０をＰＣシステム２０側に接続して表示画面を切り替えるだけで、即座にＰＣシステム２０での作業に復帰できる点にある。仮に、システム切り替え時に省電力状態にされた場合、省電力状態からの復帰処理のための時間がかかってしまうからである。また、復帰まではＰＣシステム２０への無入力が確保されているため、ＰＣシステム２０からの不要電波の放射や発熱を抑制することができる。これによって、携帯システム１０は、ＰＣシステム２０からの不要電波の影響を受けることが抑制されることになり、安定した通信を行うことができる。 The advantage of the method of FIG. 5 is that when switching back to the PC system 20 within a relatively short time after switching to the portable system 10, the virtual input device 40 is connected to the PC system 20 side and the display screen is switched. Thus, it is possible to immediately return to work on the PC system 20. This is because, if the power saving state is set at the time of system switching, it takes time to return from the power saving state. In addition, since no input to the PC system 20 is ensured until the return, emission of unnecessary radio waves from the PC system 20 and heat generation can be suppressed. Accordingly, the portable system 10 is suppressed from being affected by unnecessary radio waves from the PC system 20, and can perform stable communication.
　これについてさらに利便性と省電力性を高めるために、携帯システム１０の割り込み使用が一定時間以上になった場合に、携帯アプリケーションプロセッサ３７からＰＣシステム２０に電力制御信号（図４の制御信号Ｃ）を送ることが考えられる。 In order to further improve convenience and power saving, a power control signal (control signal C in FIG. 4) is sent from the portable application processor 37 to the PC system 20 when the interruption use of the portable system 10 has exceeded a predetermined time. Can be considered.
　図６は、システム切り替え時の省電力制御のシーケンス図である。ステップＳ２０１で携帯装置においてＰＣシステム２０が使用されている。この状態で、携帯システム１０は所定のイベントの発生を検出する（Ｓ２０２）。所定のイベントは、携帯への着信、システム切り替えスイッチ５の操作などである。イベント検出に応じて、携帯システム１０（すなわち携帯アプリケーションプロセッサ３７）は、ＰＣシステム２０の仮想入力デバイス４０の切り離しを行なう（Ｓ２０３）。これにより、入力デバイス４０は仮想的にＰＣシステム２０から切り離され、ＰＣシステム２０は省電力制御への移行準備状態に入る。 FIG. 6 is a sequence diagram of power saving control at the time of system switching. In step S201, the PC system 20 is used in the portable device. In this state, the portable system 10 detects the occurrence of a predetermined event (S202). The predetermined event is an incoming call to the mobile phone, an operation of the system switch 5 or the like. In response to the event detection, the mobile system 10 (that is, the mobile application processor 37) disconnects the virtual input device 40 of the PC system 20 (S203). As a result, the input device 40 is virtually disconnected from the PC system 20, and the PC system 20 enters a state of preparing for shifting to power saving control.
　携帯アプリケーションプロセッサ３７は、表示部（ＬＣＤ）３０の表示を、ＰＣシステム２０側から携帯システム１０側に切り替えて（Ｓ２０４）、タイマを開始する（Ｓ２０５）。仮想入力デバイス４０の切り離し（Ｓ２０３）、システム映像の切り替え（Ｓ２０４）、及びタイマ開始（Ｓ２０５）は、同時に行なわれてもよい。 The portable application processor 37 switches the display on the display unit (LCD) 30 from the PC system 20 side to the portable system 10 side (S204), and starts a timer (S205). The disconnection of the virtual input device 40 (S203), the switching of the system image (S204), and the timer start (S205) may be performed simultaneously.
　携帯システム１０が、通話、着信の確認、電子メール等で使用される間（Ｓ２０６）、一定時間の経過がモニタされる（Ｓ２０７）。一定時間が経過した場合は（Ｓ２０７でＹＥＳ）、省電力への移行制御が行われる（Ｓ２０８）。すなわち、図４の携帯アプリケーションプロセッサ３７の表示・電力制御部１４にて省電力制御信号が生成され、通信インタフェース１６を介してＰＣシステム２０に送信される。ＰＣシステム２０の表示・電源制御部２２は、ＰＣシステム２０を省電力状態へと移行させる（Ｓ２０９）。このとき、ＰＣシステム２０は認識していないが、省電力への移行準備状態（入力なしの状態）から、省電力状態へ移行することになる。その後、一定間隔でウェイクアップするか、あるいは携帯アプリケーションプロセッサ３７からの指示を待つ（Ｓ２１０）。 While the mobile system 10 is used for a call, confirmation of incoming call, e-mail, etc. (S206), the passage of a certain time is monitored (S207). If the predetermined time has elapsed (YES in S207), control for shifting to power saving is performed (S208). That is, the display / power control unit 14 of the portable application processor 37 in FIG. 4 generates a power saving control signal and transmits it to the PC system 20 via the communication interface 16. The display / power control unit 22 of the PC system 20 shifts the PC system 20 to the power saving state (S209). At this time, the PC system 20 does not recognize, but shifts from a power saving transition preparation state (no input state) to a power saving state. Thereafter, it wakes up at regular intervals or waits for an instruction from the portable application processor 37 (S210).
　携帯システム１０の使用が終わると、システム切り替えスイッチ５が操作されて、ＰＣシステム２０側へシステムが切り替えられる（Ｓ２１１）。携帯アプリケーションプロセッサ３７は、インタフェース３５を接続することによって、入力デバイス４０を仮想的にＰＣシステム２０へと接続する（Ｓ２１２）。これにより、入力デバイス４０をＰＣシステム２０の入力デバイスとして使用することができるようになる。なお、ＰＣシステム２０のオペレーションシステムが自律的に省電力動作する場合は、タイマのタイムアップ時間を、ＰＣシステム２０の自律省電力機能の設定よりも短くしてもよい。 When the use of the portable system 10 is finished, the system switch 5 is operated to switch the system to the PC system 20 side (S211). The portable application processor 37 virtually connects the input device 40 to the PC system 20 by connecting the interface 35 (S212). Thereby, the input device 40 can be used as an input device of the PC system 20. When the operation system of the PC system 20 autonomously performs power saving operation, the timer time-up time may be shorter than the setting of the autonomous power saving function of the PC system 20.
　上述した携帯アプリケーションプロセッサの動作をコンピュータプログラムにて実現することができる。その場合は、コンピュータプログラムは携帯アプリケーションプロセッサ３７に次の手順を行なわせる。すなわち、(i)ＰＣシステム２０が使用される場合に、携帯アプリケーションプロセッサ３７に接続されている入力部４０をＰＣシステム２０に対して仮想的に接続させる手順と、(ii)ＰＣシステム２０の使用中に携帯システム１０を使用するイベントが発生した場合に入力部４０をＰＣシステム２０から切り離す手順、を行なわせる。 The operation of the portable application processor described above can be realized by a computer program. In that case, the computer program causes the portable application processor 37 to perform the following procedure. That is, (i) when the PC system 20 is used, a procedure for virtually connecting the input unit 40 connected to the portable application processor 37 to the PC system 20, and (ii) use of the PC system 20 A procedure for disconnecting the input unit 40 from the PC system 20 when an event using the portable system 10 occurs is performed.
　以上説明した構成と機能により、システムごとの制御信号を増加させずに切り替え制御を行いつつ、発熱とノイズ発生を抑制することができる。また、携帯システム１０の割り込み動作が短時間の場合のＰＣシステム２０への動作復帰を、迅速に行なうことができる。また、システム間での動作復帰のタイミングを考慮しつつ、省電力制御をすることができる。 With the configuration and function described above, heat generation and noise generation can be suppressed while switching control is performed without increasing the control signal for each system. Further, the operation return to the PC system 20 when the interrupt operation of the portable system 10 is short can be quickly performed. In addition, it is possible to perform power saving control while taking into account the timing of operation return between systems.
　なお、本実施例においては、携帯システム１０およびＰＣシステム２０が動作する処理回路をそれぞれプロセッサとして例示したが、これに限られるものではない。例えば、ＦＰＧＡ（Ｆｉｅｌｄ－Ｐｒｏｇｒａｍｍａｂｌｅ　Ｇａｔｅ　Ａｒｒａｙ）や他のハードウェアロジックなどの処理回路であってもよい。 In the present embodiment, the processing circuits on which the portable system 10 and the PC system 20 operate are illustrated as processors, but the present invention is not limited to this. For example, a processing circuit such as an FPGA (Field-Programmable Gate Array) or other hardware logic may be used.
　同一装置内に内蔵された２以上の異なるシステムで表示装置を共用する場合の切り替え制御に適用可能である。 It can be applied to switching control when a display device is shared by two or more different systems built in the same device.
