嵌入式软件跟踪调试技术的研究与设计

Research and Design of Trace Debugging Technology for Embedded Software

针对在嵌入式实时操作系统环境下高低优先级任务切换过程引起的跟踪信息乱序和丢失问题,对跟踪信息嵌套缓存机制和解析机制进行了设计,提出了物理缓存管理机制与递归调用解析机制相结合、备份缓存管理机制与普通查询解析机制相结合的两种跟踪方案,解决了跟踪信息乱序和丢失问题,提高了跟踪系统的运行效率。

For the problems of out-of-order and loss of tracing information caused by switching of different priority tasks in the embedded real-time operating system, the tracing information cache and analysis mechanisms are designed, It proposed the mechanism of physical cache management combined with recursive call analysis and the mechanism of backup cache management combined with normal search analysis, solving the problems of out-of-order and loss of tracing information and improving the efficiency of tracing system.
