一种可重定向的交叉调试器实现方法

摘要

研究交叉调试工具支持后续功能可扩展的方法,设计并实现了一种可重定向的交叉调试器,使调试命令的处理过程全部运行于调试主机上,并通过调试编程接口实现对不同目标对象的挂接,以实现源码级的调试.使用该方案能够快速地实现针对不同体系架构的交叉调试器,具有开发周期短、性价比高、可移植性好的特点.%This paper researched on the method of extension for cross-dehug tools. At the same time, it designed and implemented a retargetable cross-debugger. The cross-debugger made it possible for users to finish all the debug actions in a PC. With the implementation of debug program interface( DPI) , the debugger could support source-level debug in different chips. The method above can implement cross-debuggers for different chips quickly and has the advantage of short development cycle, cost-effective, and with excellent portability.
