在研究TMS320F28x DSP 片内Flash 存储器的特性的基础上,开发了一种DSP 片内Flash 的远

程在线编程系统。该系统中,上位机通过CAN 总线向DSP 终端发送编程命令和编程数据,然后通过

DSP 自身功能实现对Flash 的在线编程。对该系统的硬件构成进行了说明,给出了具体的软件实现方

法和流程,特别是针对程序在不同存储空间的切换、Flash 中程序入口地址的修改、Flash 写入代码的生

成等技术难点进行了分析和说明。这种远程在线编程方法为DSP 系统的软件维护和升级带来了方便,

-TMS320F28x DSP chip in the study of the characteristics of Flash memory, based on the development of a DSP chip Flash programming system for remote online. This system, the host computer to the DSP via CAN bus terminal to send programming commands and programming data, and then through the DSP functionality to achieve their own line of Flash programming. The hardware configuration of the system are described, given a specific software implementation methods and processes, particularly for procedures in different storage switch, Flash changes in the program entry address, Flash write code and other technical difficulties of generating the analysis and descr iption. The remote on-line programming software for the DSP system maintenance and upgrades to bring the convenience,
