参看图 10以及图 6所示，为了方便介绍处理器对无线上网设备的单元进行电源管理的实现过程，先对图 10进行介绍，其中，三条纵向的直线分别对应终端设备或网络、处理器、被控单元的工作状态，其中，交互数据表示终端设备与网络的交互数据，图 10中的实线表示"工作状态"，虚线表示"低功耗状态"，下面基于图 10介绍处理器针对无线上网设备中的被控单元的进行电源管理的控制过程： Referring to FIG. 10 and FIG. 6 , in order to facilitate the process of implementing power management of the unit of the wireless internet device by the processor, FIG. 10 is first introduced, wherein three vertical lines respectively correspond to the terminal device or the network, the processor, The working state of the controlled unit, wherein the interaction data represents interaction data between the terminal device and the network, the solid line in FIG. 10 indicates "working state", and the broken line indicates "low power consumption state", and the processor is described below based on FIG. The control process of the power management of the controlled unit in the Internet device:

( 1 )当处理器检测在一定时间内终端设备与网络无交互数据进行传输时，处理器向被控单元发送允许休眠命令，指示被控单元进入低功耗状态；优选的，上述步骤中的一定时间可以由用户预先设定，譬如： 1分钟；或者由芯片制造商在制造芯片时写入； (1) When the processor detects that the terminal device has no interaction data with the network for transmission within a certain period of time The processor sends a permission to sleep command to the controlled unit to instruct the controlled unit to enter a low power consumption state. Preferably, the certain time in the foregoing step may be preset by the user, for example: 1 minute; or by the chip manufacturer Write when manufacturing the chip;

其中，在终端设备或者网络有交互数据需要通信时，此时处理器以及被控单元均处于工作状态； Wherein, when the terminal device or the network has interactive data to communicate, the processor and the controlled unit are in a working state at this time;

( 2 )被控单元接收到处理器发送的允许休眠命令后被控单元进入低功耗状态； (2) After the controlled unit receives the allowable sleep command sent by the processor, the controlled unit enters a low power state;

优选的，被控单元在接收到允许休眠命令后，且在进入低功耗状态之前，发送休眠命令给处理器，随后被控单元进入低功耗状态；处理器接收到休眠命令后，也自动进入低功耗状态； Preferably, after receiving the allowable sleep command, and after entering the low power consumption state, the controlled unit sends a sleep command to the processor, and then the controlled unit enters a low power consumption state; after receiving the sleep command, the processor also automatically Enter a low power state;

( 3 ) 当处理器接收到终端设备或者网络的交互数据之后，向被控单元发送唤醒命令； (3) after receiving the interaction data of the terminal device or the network, the processor sends a wake-up command to the controlled unit;

优选的，处理器接收到终端设备或者网络的交互数据之后，从低功耗状态转化为工作状态，并向被控单元发送唤醒命令； Preferably, after receiving the interaction data of the terminal device or the network, the processor converts from a low power consumption state to a working state, and sends a wakeup command to the controlled unit;

( 4 )被控单元接收到处理器发送的唤醒命令之后，从低功耗状态进入工作状态。 (4) After receiving the wake-up command sent by the processor, the controlled unit enters the working state from the low-power state.

在实际的应用场景中，上面的实施例的被控单元具体指的是： SDIO从控制器、 SD Memory从控制器、基带处理单元等。处理器在具体的控制过程中，可以基于所有的被控单元均处于低功耗状态之后，再进入低功耗状态。 In a practical application scenario, the controlled unit of the above embodiment specifically refers to: an SDIO slave controller, an SD Memory slave controller, a baseband processing unit, and the like. During the specific control process, the processor can enter the low power state after all the controlled units are in the low power state.

为了清楚、全面的描述处理器对某一被控单元的电源管理的过程，下面的实施例中，以基带处理单元为例： In order to clearly and comprehensively describe the process of the processor's power management for a controlled unit, in the following embodiments, the baseband processing unit is taken as an example:

下面通过两个具体的应用场景来说明电源管理的具体过程： The following is a detailed description of the specific process of power management through two specific application scenarios:

( 1 )第一种应用场景：参见图 11，其中三条纵向直线分别代表终端设备、处理器、基带处理单元的工作状态，其中，实线代表"工作状态"，虚线代表"低功耗状态"，处理器所进行的电源管理的实现过程为：当终端设备无交互数据，网络也无与终端设备进行交互的数据时，处理器检测到终端设备以及网络均无进行交互的数据时，发送允许休眠命令给基带处理单元； (1) The first application scenario: Referring to FIG. 11, three vertical lines respectively represent the working states of the terminal device, the processor, and the baseband processing unit, wherein the solid line represents the "working state" and the dotted line represents the "low power state". The implementation process of the power management performed by the processor is: When the terminal device has no interaction data and the network has no data to interact with the terminal device, when the processor detects that the terminal device and the network have no data for interaction, the device sends a permission to give a sleep command to the baseband processing unit;

基带处理单元接收到处理器发送的允许休眠命令后，向处理器发送休眠命令，并进入低功耗状态； After receiving the allowable sleep command sent by the processor, the baseband processing unit sends a sleep command to the processor and enters a low power consumption state;

处理器接收到休眠命令之后，自动进入低功耗状态； After receiving the sleep command, the processor automatically enters a low power state;

当基带处理单元接收到来自于网络的交互数据之后，从低功耗状态进入工作状态，并向处理器发送唤醒命令； After the baseband processing unit receives the interaction data from the network, it enters the working state from the low power consumption state, and sends a wakeup command to the processor;

处理器接收到唤醒命令之后，进入工作状态。 After the processor receives the wake-up command, it enters the working state.

( 2 )第二种应用场景：参见图 12，其中三条纵向直线分别代表终端设备、处理器、基带处理单元的工作状态，其中，实线代表"工作状态"，虚线代表"低功耗状态"，点划线代表"关闭状态"，处理器对基带处理单元进行电源管理的实现过程为： (2) The second application scenario: Referring to FIG. 12, three vertical lines respectively represent the working states of the terminal device, the processor, and the baseband processing unit, wherein the solid line represents the "working state" and the dotted line represents the "low power state". The dotted line represents the "off state". The processor implements power management for the baseband processing unit as follows:

处理器检测到终端设备较长时间（譬如： 1分钟，上述时间可以由用户在使用无线上网设备时根据需要设定，也可以在芯片的制造过程中，由制造商写入在芯片中）与网络无交互数据进行传输时，就会向基带处理单元发送关闭命令，基带处理单元接收到该关闭命令之后，就下电进入关闭状态，当终端设备有交互数据业务需求时，向处理器发出请求，处理器接收到该请求后就会向基带处理单元发送上电命令，基带处理单元接收到该上电命令之后，即上电进入工作状态。 The processor detects the terminal device for a long time (for example: 1 minute, the time can be set by the user when using the wireless internet device, or can be written by the manufacturer in the chip during the manufacturing process of the chip) When the network transmits without interactive data, it sends a shutdown command to the baseband processing unit. After receiving the shutdown command, the baseband processing unit is powered off and enters the shutdown state. When the terminal device has an interactive data service request, the base device sends a request to the processor. After receiving the request, the processor sends a power-on command to the baseband processing unit. After receiving the power-on command, the baseband processing unit powers on and enters the working state.

需要说明的是，上面的实施例是由处理器实现对基带处理单元的电源管理的过程，对于图 6中的 SD控制芯片的其他的单元（譬如： SDIO从控制器、 SD Memory从控制器、以及存储单元），处理器可以采用上面类似的方式实现对这些单元的电源管理，为了更清楚地说明处理器对于 SD控制芯器进行介绍：在终端设备通过无线上网设备实现对无线上网设备的存储单元的访问或者通过无线上网设备实现与网络的通信过程中，当检测到终端设备不具备 SDIO的支持能力，则可以向 SDIO从控制器发出允许休眠命令，或者关闭命令，使 SDIO从控制器处于低功耗状态或者关闭状态，以降低能耗。 It should be noted that the above embodiment is a process of implementing power management of the baseband processing unit by the processor, and other units of the SD control chip in FIG. 6 (for example: SDIO slave controller, SD Memory slave controller, And the storage unit), the processor can implement power management of these units in a similar manner as above, in order to more clearly explain the processor for the SD control core: In the process of the terminal device accessing the storage unit of the wireless internet device through the wireless internet device or the communication with the network through the wireless internet device, when detecting that the terminal device does not have the support capability of the SDIO, the terminal device may send the SDIO to the controller. Allow the sleep command, or close the command, to put the SDIO slave controller in a low power state or off state to reduce power consumption.

对于 SD Memory从控制器，当该终端设备不支持 SD Memory工作模式实现终端设备与网络的通信时，处理器可以向 SD Memory从控制器发出允许休眠命令，或者关闭命令，使 SDIO从控制器处于低功耗状态或者关闭状态，以降低能耗；同时，该 SD Memory从控制器在进入低功耗状态或者使存储单元进入相应的状态，达到节能的目的；当需要利用 SD Memory从控制器实现终端设备对存储单元的数据的存取操作时，则向该 SD Memory 从控制器发送唤醒命令，或者上电命令，促使 SD Memory从控制器唤醒或者上电，使 SD Memory从控制器进入工作状态，同时 SD Memory从控制器也向存储单元发送唤醒或者上电命令，使存储单元也进入工作状态。 For the SD Memory slave controller, when the terminal device does not support the SD Memory working mode to implement communication between the terminal device and the network, the processor may issue an allow sleep command to the SD Memory slave controller, or close the command to make the SDIO slave controller Low power state or off state to reduce power consumption; At the same time, the SD Memory slave controller enters a low power state or puts the memory unit into a corresponding state to achieve energy saving purposes; when it is necessary to use SD Memory to implement the terminal from the controller When the device accesses the data of the storage unit, it sends a wake-up command to the SD Memory slave controller, or a power-on command, causing the SD Memory to wake up or power up from the controller, so that the SD Memory enters the working state from the controller. At the same time, the SD Memory slave controller also sends a wake-up or power-on command to the memory unit, so that the memory unit also enters the working state.

可以理解，处理器也能够实现不与之直接相连的单元的电源管理操作，如图 7所示，所述无线上网设备还包括：射频处理单元，当处理器检测到终端设备或者网络无交互数据进行传输时，则可以通过基带处理单元向射频处理单元发送休眠命令或者关闭命令，使该单元进入低功耗状态或者关闭状态，从而降低能耗。 It can be understood that the processor can also implement the power management operation of the unit that is not directly connected thereto. As shown in FIG. 7, the wireless network device further includes: a radio frequency processing unit, when the processor detects that the terminal device or the network has no interaction data. When the transmission is performed, the baseband processing unit may send a sleep command or a close command to the radio frequency processing unit, so that the unit enters a low power state or a closed state, thereby reducing energy consumption.

另外，在基带处理单元实现终端设备与网络的数据进行交互的过程中，需要基带处理单元运行相应的固件（ Firmware , 写入 EROM或 EPROM中的程序），针对基带处理单元的固件存储位置，有两种实现方式： In addition, in the process of the baseband processing unit implementing the interaction between the terminal device and the data of the network, the baseband processing unit is required to run the corresponding firmware (firmware, program written in the EROM or EPROM), and the firmware storage location of the baseband processing unit is Two ways to achieve:

( 1 )在基带处理单元中集成附加的存储单元，用于存储基带处理单元运行时的相应的固件； (1) integrating an additional storage unit in the baseband processing unit for storing the corresponding firmware when the baseband processing unit is in operation;

( 2 )利用无线上网设备中的存储单元存储基带处理单元的固件，当基带处理单元上电运行时，利用 SD控制芯片中的处理器控制 SD Memory从控制器读取在该存储单元中的固件，并加载到基带处理单元中，使得基带处理单元能够执行相应的固件，实现终端设备与网络进行数据交互过程中的基带信号处理的功能。 (2) using the storage unit in the wireless internet device to store the firmware of the baseband processing unit, and when the baseband processing unit is powered on, the SD memory is controlled by the processor in the SD control chip. The controller reads the firmware in the storage unit and loads it into the baseband processing unit, so that the baseband processing unit can execute the corresponding firmware to implement the function of baseband signal processing in the data interaction between the terminal device and the network.

采用上述实施方式，能够更好的利用无线上网设备的存储单元，而不用在基带处理单元集成附加的存储单元，减少产品实现的复杂度以及降低产品实现的成本。 With the above implementation manner, the storage unit of the wireless internet device can be better utilized without integrating the additional storage unit in the baseband processing unit, thereby reducing the complexity of product implementation and reducing the cost of product realization.
