| 摘要: |
| 片上trace技术弥补了传统调试方法的不足，可以实现对嵌入式软件的非入侵调试。首先分析了当前主流调试方法的不足，论述了trace与断点调试方法互为补充的关系，而后介绍了YHFT系列DSP的片上trace系统TraceDo的功能与结构，并解释了路径trace的原理和工作过程，最后讨论了片上trace的应用。 |

| Abstract: |
| To overcome the shortcomings of traditional techniques for non-intrusive debug and optimization, the on-chip trace system was adopted to record run-time information of embedded processor with special hardware. To fill the vacancy of former study, this paper gives a deep view of the mechanism, characteristics and applications of on-chip trace technique with TraceDo, an on-chip trace system of a multi-core SoC. The functions and structures of TraceDo were introduced, the working process of path trace was explained and trace applications were also discussed. |
