介紹了DSP 與CPLD 協同控制的高速圖像通信系統的設計。整個圖像通信系統由圖像采集、圖像信號的處理和控制、USB 傳輸和控制、系統接口以及終端的圖像還原和存儲等
幾部分組成。系統采用高速USB2.0 作為圖像傳輸的接口。該系統已成功應用于一個圖像處理和識別的高速和高精度工業項目中，由于圖像信號不經過壓縮處理對后續處理沒有任何影響，因此這種圖像處理和識別的效果比一般的圖像采集要好，滿足了特殊場合的特殊需要。關鍵字：機器視覺;數字信號處理系統;復雜可編程邏輯器件;圖像采集;圖像處理
Abstract: A design of high-speed image communication system which is controlled coordinately by DSP and the CPLD is introduced. The entire image communication system consists of image capture, image signal processing and the control, the USB transmission and the control, the terminal image return and storage and so on. The system uses high-speed USB2.0 interface as image transmission. This system has been applied successfully in a high-speed and high-accuracy industrial project of an image processing and the recognition. The image signal not passing through compression processing does not influence the following processing, therefore, compared with general image capture, the effect of the image processing and the recognition is better and it has met the special needs for special occasion.
