摘要

TMS320C25是一种高速数字信号处理器

由于它的高速性

要求开发系统的仿真头电缆线尽量短

这就给实际联调或外场实验中调试程序带来许多不便

此外

TMS320C25的程序一般固化在E-PROM中

联调时要反复修改程序就需反复擦写EPROM

本文介绍了一种TMS320C25的在线编程方法

该方法脱离开TMS320C25的开发系统

利用微机串口直接将微机中的程序写入TMS320C25的外部存储器RAM中

避免了反复擦写EPROM

给实际联调工作带来了极大方便.

Abstract

TMS320C25 is a high speed digital signal processor. Because it works at a high speed

the length of the emulator cable should be as short as possible. Sometimes we need modify the program and erase the EPROM frequently

which is very inconvenient

especially while we debug the program on the outside site. This paper introduces a method of in-system programming about TMS320C25. This method is independent of TMS320C25 emulator. It loads code from computer immediately and transfer it to external program memory of TMS320C25 using computer serial port. This avoids erasing and programming EPROM time after time.
