基于GDB的ARM硬件调试系统的设计

The Design of an ARM Hardware Debugging System Based on GDB

远程调试是调试嵌入式系统的基本方式。GDB是一款被广泛使用的调试器，但是GDB的孳程调试方案不能完全满足调冀系统开发中的调试需求。文中介绍了一种利用ARM处理器硬件调试模块，扩展GDB远程调试功能的方。案。并以ARM920T处理器为例，描述了该方案的设计与关键功能实现原理。

Remote debugging is the basic pattern of debugging the embedded system, GDB is a widely used debugger, but the method of remote debugging within GDB cann＇t meet the full requirements of the embedded development. A method to extend GDB is introduced, using the hardware debugging module in ARM processors. And its design and the theory of its key functions are described, by taking the ARM920T processor for example.
