面向自主可控DSP的调试系统软硬件设计

Hardware and Software Design of Debug System for DSP

本文首先介绍了面向自主可控DSP的调试系统总体设计方案,对其硬件架构进行了阐述,并分析了其工作原理。随后给出了固件程序开发、驱动程序开发,同时对调试代理程序的通信协议实现过程及实现流程进行描述。利用该调试系统,上位机工具链可以实现对目标DSP的在线调试和在线编程。

Firstly,this paper introduces the overall design of DSP-oriented debugging system,describes its hardware architecture and analyzes its working principle.Then the firmware development and driver development are given,and the communication proto⁃col implementation process and implementation flow of debugging agent are described.Using this debugging system,the upper computer tool chain can realize the on-line debugging and on-line programming of the target DSP.
