Abstract
The invention relates to a mobile phone, which comprises a central processing unit (CPU) and an image processing chip, wherein the model number of the CPU is MT6223D; and the image processing chip is connected with the CPU through an external memory interface (EMI) bus, and the model number of the image processing chip is AIT701U. By the technical scheme, the MT6223D-platform-based mobile phone can decode a multimedia file by adopting the image processing chip with the model number of AIT701U without adopting software only, so that decoding speed can be optimized, and a customer can be visually satisfied; and in addition, the MT6223D-platform-based mobile phone decoding the multimedia file by adopting the image processing chip with the model number of AIT701U can reach the image processing level of an MT6225-platform-based mobile phone, but the cost of the MT6223D-platform-based mobile phone is far lower than that of the MT6225-platform-based mobile phone.
Description
Technical field
The present invention relates to mobile communication technology, more particularly, relate to a kind of mobile phone.
Background technology
Along with the function as the mobile phone of mobile communication terminal constantly increases, generally all be equiped with display screen on the mobile phone, can display frame or image on this display screen, even can show or play FLASH animation etc.But existing mobile phone based on the MT6223D platform is owing to rely on pure software to come multimedia files such as MP4,3GP, RMVB are decoded, and decoding speed is slow, can't make the client visually reach satisfied.
Summary of the invention
The technical problem that the present invention will solve is, to the above-mentioned mobile phone of the prior art slow defective of decoding speed to multimedia files such as MP4,3GP, RMVB, the mobile phone that provides a kind of decoding speed to optimize.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of mobile phone based on the MT6223D platform; Comprise that model is the CPU of MT6223D, said mobile phone also comprises and being connected through the EMI bus with said CPU and model is the picture processing chip of AIT701U.
In mobile phone of the present invention, said mobile phone also comprises the camera that is connected with said picture processing chip.
In mobile phone of the present invention, said mobile phone also comprises the USB interface that is connected with said picture processing chip.
In mobile phone of the present invention, said mobile phone also comprises the T card that is connected with said picture processing chip.
In mobile phone of the present invention, said mobile phone also comprises the LCD display that is connected with said picture processing chip.
In mobile phone of the present invention, said CPU is according to the state of mode of operation switching picture processing chip, and said mode of operation comprises camera pattern, USB pattern, T mode card, LCD pattern, bypass mode.
The technical scheme of embodiment of the present invention has following beneficial effect:
1. because can to adopt model based on the mobile phone of MT6223D platform be that the picture processing chip of AIT701U is decoded to multimedia file, need not to adopt pure software decoding multimedia file, therefore can optimize decoding speed, make the client visually reach satisfied.In addition, the picture processing chip that this mobile phone employing model based on the MT6223D platform be AIT701U is decoded to multimedia file and can be reached the image processing level based on the mobile phone of MT6225 platform, but cost will be far below the mobile phone based on the MT6225 platform.
2. after adopting model to be the picture processing chip of AIT701U based on the mobile phone of MT6223D platform, can connect devices such as camera, T card, USB interface, so just expand function based on the mobile phone of MT6223D platform.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the logic diagram of mobile phone embodiment one of the present invention;
Fig. 2 is the logic diagram of mobile phone embodiment two of the present invention;
Fig. 3 is the circuit diagram of picture processing chip embodiment one among Fig. 2 of the present invention.
Embodiment
As shown in Figure 1, in the logic diagram of mobile phone embodiment one of the present invention, this mobile phone comprises CPU 100 and the picture processing chip 200 that is connected through the EMI bus with CPU 100.Wherein, CPU 100 is the integrated chip of MT6223D for model, and picture processing chip 200 is the integrated chip of AIT701U for model.
Implement the technical scheme of this embodiment; Because should can adopt model based on mobile phone of MT6223D platform is that the picture processing chip of AIT701U is decoded to multimedia file; Need not to adopt pure software decoding multimedia file, therefore can optimize decoding speed, make the client visually reach satisfied.In addition, the picture processing chip that this mobile phone employing model based on the MT6223D platform be AIT701U is decoded to multimedia file and can be reached the image processing level based on the mobile phone of MT6225 platform, but cost will be far below the mobile phone based on the MT6225 platform.
In the logic diagram of the mobile phone embodiment two of the present invention shown in Fig. 2, this mobile phone comprises CPU 100, picture processing chip 200, camera 300, USB interface 400, LCD display 500 and T card 600.Wherein, CPU 100 is the integrated chip of MT6223D for model; Picture processing chip 200 is the integrated chip of AIT701U for model; Picture processing chip 200 is connected through the EMI bus with CPU 100, and camera 300, USB interface 400, LCD display 500 and T card 600 are connected with picture processing chip 200 respectively.Model is being connected please with reference to circuit diagram shown in Figure 3 of other part of picture processing chip and the mobile phone of AIT701U.In conjunction with Fig. 2 and Fig. 3; CPU 100 at first downloads to the firmware program of being stored in the memory in the picture processing chip of AIT701U through the EMI bus; And according to the state of the picture processing chip of different working mode switch AIT701U; As: if mode of operation is the camera pattern, promptly use the camera 300 on the mobile phone to take pictures, then the state with the picture processing chip of AIT701U switches to the camera user mode; At this moment, the captured view data of camera gets into the picture processing chip of AIT701U through the PD0-PD7 pin; If mode of operation is the USB pattern, then the state with the picture processing chip of AIT701U switches to the state that USB interface 400 uses; If mode of operation is the T mode card, then the state with the picture processing chip of AIT701U switches to the state that T card 600 uses; If mode of operation is the LCD pattern, then the state with the picture processing chip of AIT701U switches to the state that LCD display 500 uses; If mode of operation is bypass mode, then the state with the picture processing chip of AIT701U switches to all obsolete state of camera 300, USB interface 400, LCD display 500 and T card 600.When the picture processing chip that adopts this AIT701U is decoded to multimedia files such as MP4,3GP; CPU 100 at first moves into yuv data in the inner buffer of the picture processing chip of AIT701U; And relevant register is set begins to convert yuv data to the RGB data, adjust the size of image then as required.After the picture processing chip of AIT701U is accomplished image processing, to LCD display, show the RGB Refresh Data of output.
