摘　　要：针对以TMS320C6713B为核心的某嵌入式系统要求通过RS422/485进行系统应用软件的加载与固化,摆脱JTAG口调试电缆的长度限制的问题,描述了一种采用RS422/485进行软件加载与BOOTLOAD的设计方法,从硬件设计、软件设计两大方面说明基于C6713B的远程软件加载系统的实现,对TMS320C6713B使用DSP/BIOS配置、EMIF总线外挂大容量SDRAM等一些新特点进行软件加载系统的设计,从而满足了嵌入式系统对远程加载软件大数据量,快速传输的要求。To get rid of length limitation of the JTAG debug cable in an embedded system based on TMS320C6713B,a software uploading method through RS422/485 is required. Design of realizaing soft- ware uploading and BOOTLOAD based on RS422/485 Bus is provided in this paper. Implement of remote software uploading System based on C6713B is described detailedly in both hardware and software as- pects. Software uploading System＇s design is achieved with new characteristic such as DSP/BIOS configu- ration, EMIF bus and large- capacity SDRAM. Thus requirements of high throughout and fast transmission are satisfied.
