摘　　要：给出了一种CCD图像识别装置的设计方法,该装置以ARM与FPGA为主控芯片,设计了基于Nios II的A/D控制模块并行控制多路CCD图像信号的数据采集和基于Nios II的多种内核,重点介绍了基于Nios II的LCD驱动以实现液晶显示、设计A/D采样控制模块以实现多路数据采集以及设计SL811HS驱动以实现ARM与PC的USB通信等。实验结果表明系统具有应用价值高、速度高、可靠性高、故障少等优点。A sort of design technique of CCD image recognition apparatus was presented. This apparatus regarded ARM and FPGA as master control chip. Concurrent control multiple channel data acquisition of CCD image signal based on Nios Ⅱ and many core based on Nios Ⅱ were devised. This paper mainly introduced the design of LCD drive based on Nios Ⅱ for realizing LCD display, the design of A/D sampling control module for realizing multiple channel data acquisition, the design of SL811HS drive for realizing USB correspondence of ARM and PC and so on. Experiments show that this system has the advantages of high application value, high rate, high reliability and less accident.
