基于AVR和CPLD的数字图像采集系统

The Digital image sampling system with AVR and CPLD

本文介绍了一种基于AVR单片机和CPLD组成的嵌入式数字图像采集系统。通过CMOS图像传感器与GPLD进行时序匹配后将图像数据直接写入系统存储区SRAM内,MCU通过访问SRAM获得图像数据后,既可以运用相关算法自行处理,也可以将数据传输至PC机处理,灵活地实现了高速图像采集。

In this paper, we present a digital Image sampling system with AVR and CPLD. The data of the CMOS image sensor is directly writed to the SRAM though the timing interface in the CPLD.the MCU directly read the data of SRAM and send the data to PC or handle the data with the software of itself. This method can complete the high speed image sampling in a new method.
