In order to satisfy the requirement of mobile data exchange, it ’ s necessary to research and develop embedded usb host system. to solve this problem, usb otg ( usb on - the - go ) is one of the best choices
為了滿足人們對移動數據交換需求的日益擴大，迫切需要研究開發嵌入式的usb主機系統， usbotg （ usbon - the - go ）技術是解決這個問題的一個不錯的選擇。 -
It ’ s not a good idea to embedded otg to all the peripherals. because first this may increase cost, second sometime these peripherals can not be linked each other. we can develop a new device which contains usb host and peripherals
如果為每一臺外設都設計otg功能，顯然這樣的做法不太合理:一是這樣的設計增加了成本，二是有些外設之間由於距離等因素無法互連。 -
For the image acquisition of optical scan mode, normally, ccd image sensor is used to capture image, but in our system, due to the system request of micromation and high integration, cmos image sensor is adopted as the image collection device, and then the thesis gives a interface circuit between the chip and dsp and a control solution of image collection ; toward the information storage in our solution, dsp is directly linked to usb host chip and it is the dsp that accomplishes the processing of usb protocol and interface control so as to reduce the cost, minimize product cubage and consequently meet the requirement of system micromation ; at the same time, the thesis probes preliminarily into usb otg ( on - the - go ) technology, which offers an approach between embedded machines including pda, mobile phone, printer, digital camera and so on ; in addition, some attempts on the other application area with tms320vc5402 which was commonly used to voice processing and static image processing are done, for example, to arrange the chip to control lcd module directly
在圖像的光電掃描輸入上，傳統方案大部分採用ccd型圖像傳感器，而在本方案中，根據系統微型化、高集成的特點，使用了cmos圖像傳感器作為攝像器件，並且設計了該晶元與dsp的一種介面電路以及圖像採集控制方案；在信息存儲上，本方案採用dsp直接與usbhost晶元連接，由dsp處理usb協議和介面信息，從而降低了系統成本、縮小了產品體積，滿足了系統微型化的要求；同時本論文也對usb - otg技術進行了初步探討，利用此項技術，不再需要計算機作為主機，就能實現在pda 、移動電話、印表機、數碼相機等嵌入式應用之間直接互聯通信；另外也對廣泛用於語音處理和靜態圖像處理的tms320vc5402其它方面的應用進行了嘗試，比如直接控制液晶顯示器等。
