Trace调试技术是一种非侵入式的、需要硬件支持的调试技术。该技术需要设置监视点,在监视点触发时将当前调试信息存入缓冲区中,以便程序运行后读取并解析这些数据,从而分析监视点触发时程序的运行状态。然而,目前片上Trace技术使用的协议不同,对Trace数据的处理也不同。本文针对ARM架构的国产芯片FT-2000/4提出一种新的Trace数据解析办法,为集成开发环境提供Trace功能方面的支持。

Trace debugging technology is a non-invasive debugging technology that needs hardware support.The technology needs to set up monitoring points to store the current debugging information in the buffer area when the monitoring point is triggered,so that the data can be read and parsed after the program runs,so as to analyze the running state of the program when the monitoring point is triggered.However,at present,the protocols used in on-chip trace technology are different,and the processing of trace data is also different.In the paper,a new trace data analysis method for the domestic chip FT-2000/4 with ARM architecture is proposed,which provides trace support for the integrated development environment.
