摘　　要：为了解决高像素 CMOS 图像采集传感器 MT9T001和一些没有视频采集控制器的 DSP 接口难的问题,采用了2KB 容量的线缓冲 FIFO+CPLD 的方案,结合 TI 公司的6000系列 DSP 芯片TMS320C6711的 EMIF 接口,在 DSP 中设计了采集图像的中断程序,通过 DSP 将采集的图像写到 SD卡中,最终证明了本采集方案的可行。To solve the problem of the interface between the high resolution CMOS image sensor MT9T001 and some universe DSP processors with no video controller. We adopt a project which connects a 2kB FIFO acting as a line buffer to CPLD, and combines the EMIF interface of TMS320C6711 which is the 6000 series chip made by TI corporation. At the same time, we designe the image acquiring interrupt program on DSP. By writing the acquired image data to SD card ,it is proved to be a feasible project.
