一种基于TMS320C6205 DSP的在线升级方法

提出了一种基于TMS320C6205 DSP的软件在线升级方法,该方法通过用户固化的Userbootloader升级更新应用程序,对升级的应用程序没有固定应用程序入口的限制,也不需要做中断向量的动态重定位。以一个PCI-E卡系统为例,介绍了系统的体系结构、硬件设计和软件设计,描述了DSP系统进入正常应用状态时加载应用程序、在升级状态下进行升级的具体流程。经实际验证,该升级方法提高了系统的通用性、灵活性和可维护性。

An On-line Upgrading Method based on TMS320C6205 DSP

This paper proposes an online software upgrading method based on TMS320C6205 DSP. The DSP application could be updated via the user-developed bootloader without any fix address of code entry point and interrupt vector redirection. With PCI-E card as an example, this paper describes the framework, hardware and software design of the upgrading system, gives the booting process for entering the normal working state and the upgrading process under upgrading state. Actual test indicates that this upgrading method could improves versatility, flexibility and maintainability of the system.
