摘　　要：提出一种通过存储器地址映射的方式实现对DSP嵌入式系统片外FLASH擦写的方法。文中介绍的程序有一定参考价值。When we design embedded systems, the erasion and writing of off-chip flash memoriesare always necessary but difficult to realize. By using the technique of memory imaging, we devel-oped a novel method to solve the problem and successfully implemented the on-line erasion andwriting of off-chip flash memories on motorola DSP56800 board. The method presented in this articleis valuable for the practice.
