摘　　要：设计了一种基于CPLD、USB2.0和单色CCD的数字图像采集系统。首先介绍了系统的结构和工作原理,然后介绍了系统各模块的特点并给出了产生这些模块驱动和控制时序程序的原理,最后给出了时序仿真的结果,得出所有时序逻辑满足系统要求的结论。A digital image acquisition system was designed based on CPLD, USB2.0 and Monochrome CCD. The principle and structure of the system are introduced, and then explained the features of each part and the principles of the programs generating the driver or control signals for them. Finally the time Simulation results are gaven out and drew the conclusion that all of the sequential logics meet the requests of the system.
