On-chip Trace: Effective Debug and Optimization Technique for Embedded Processor
Chen Li-li · Journal of National University of Defense Technology · 2008
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.
