摘要
在图像采集处理系统中,由于采集到的数据量较大以及处理算法的复杂性,TMS320VC5402内部存储资源有限,远远不能满足需要,因此需要外扩存储器。提出了一种基于CPLD实现的存储器扩展方案,分别对VC5402的程序存储空间、数据存储空间和I/O端口进行扩展,此方法接口灵活,便于控制,为其他便携式图像采集处理系统的存储器扩展提供了一些有价值的参考。
Owing to the large amount of data and the complexity of processing arithmetic in the image acquisition and processing system, the limited inner resource of TMS320VC5402 can＇t meet the demands,so it is important to extend the memo ry. One scheme of the extended memory based on CPLD is introduced, which extends the program memory, the data memory and the I/O port separately. With the advantage of the flexible interface and the convenience of controlling, this method offers some valuable references for the extended memory of other portable image acquisition and processing systems.
