Enforcement by the utility model " portable digital image signal processor ", the ability of following portable apparatus for image processing can be provided, utilize advanced Intelligent rod (Intelligent Stick) memory card technologies, digital image signal is handled (Graphic Process) to be integrated in the Intelligent rod, and reach can with portable apparatus, be used in combination as PDA etc., and then increase the ability of portable apparatus digital image processing.

Description of drawings

Fig. 1 is the system block diagram of the utility model device;

Fig. 2 is the interface layout figure of Intelligent rod;

Fig. 3 is a schematic appearance of the present utility model.

Embodiment

At first, Figure 1 shows that the system block diagrams of the utility model device with reference to figure 1, comprising, one, 101 is an interfacial level controller, it is responsible for the transmission of image data, and this device and portable apparatus are provided, as the connection between the PDA; One, 102 is a high speed image processing arithmetic element, and it has the ability of an image data computing, 104 required high-speed memory during then as 102 computings of high speed image processing arithmetic element, and it can be volatile storages such as SDRAM or SRAM; If this memory span is little, then can be designed to and 102 be integrated into image data processor with high-speed memory unit; 103 then is 3D image data storehouse, and it can be a nonvolatile flash memory component and constitutes, must the 3D image data then can see through 101 interfaces that provided and pc connection and obtain downloaded data, required data parameter with as 102 computings the time.

Further be discussed below, as above say, because must being connected with PC (PC), this device downloads image data, and must be connected with portable apparatus simultaneously, therefore 101 interfacial level controller can be designed to the controller at a pair of interface, as adopting USB interface and MMC interface, the former can be connected with computer platform by USB, and the latter can provide conduct and portable apparatus, as PDA, and the connection of mobile phone etc.When desiring on portable apparatus, to quicken to improve the ability of image data processing, as game machine, then can insert one and have the image signal processor of the utility model design with the processing of quickening image or virtual the presenting that increases the 3D image, and at present the most suitable on the market general design collocation product, it promptly is the Intelligent rod (Intelligent Stick) at USB interface, but the Intelligent rod of being seen on the market at present all only provides the USB interface of 4Pin, remaining pin position is all less than using, therefore can utilize remaining 6Pin, finish the image processing at above-mentioned pair of interface easily and quicken Intelligent rod.
