摘　　要：为了解决目前嵌入式设备程序升级维护困难、成本高昂的问题,设计了一种DSP(digital signal processor,数字信号处理器)程序远程升级的方案。该方案在硬件上提出了基于GPRS(general packet radio service,通用分组无线业务)通信模块的系统结构,实现了远程无线通信。提出了软件的设计方法,在分析了目前主要HEX(十六进制)文件格式的基础上,通过VC++6.0编程环境开发了程序代码的生成软件,实现了从编译器输出的通用对象文件到可烧写的二进制文件的转换。利用DSP的启动原理和FLASH烧写技术,在TI公司的TMSF2812DSP上验证了该方案,验证结果表明了该方案有效可行且降低了系统的升级和维护成本。To solve the problems of the maintenance difficulties and to reduce the cost on software updating of the embedded device,a method for software remote upgrading of DSP program based on GPRS wireless technologies is presented.A hardware structure of this method based on the GPRS Module is proposed to realize remote wireless communication.And the solution of software is proposed,after the formats of HEX file are analyzed,the software is developed to generate software code by using of VC＋＋6.0 language,to realize a conversion from COFF format file outputted by a compiler to BIN format file which can be burned directly.This method is validated on TMSF2812 DSP by using the boot load theory of DSP and online burned Technology of FLASH.This method reduces the cost of upgrade and maintenance,and the validity and efficiency of the presented method is demonstrated.
