介绍MT9V011 CMOS数字图像传感器在一个基于低端ARM7处理器和CPLD(可编程逻辑器件)的嵌入式系统中的应用。通过一片CPLD读取MT9V011采集的图像并缓存到存储器以备后续的处理。利用PC平台验证了图像采集功能。给出了一个在低端嵌入式系统中增加图像采集功能的实现方案。-Introduction MT9V011 CMOS digital image sensor in a low-end ARM7-based processor and CPLD (Programmable Logic Device) embedded systems. CPLD to read through a collection of images and MT9V011 cache memory to prepare for the follow-up treatment. Validate the use of PC platform, image capture function. Given a low-end embedded systems increase the image acquisition function in the realization of the program.
