Abstract:

Motivated by the concurrent debugging and real-time debugging in a multi-core processor （YHFT-QDSP）, a debug system which supports multi-core debugg  ing and real-time on-chip tracing is developed based on the one-core debug system. Multi-core debugging supports debug command broadcasting and breakpoi nt trigger synchronization. On-chip tracing records program execution information such as path and data accesses by special hardware for non-intrusive d ebugging. The mechanism, structure and realization of the system are introduced in this paper.

Key words: multi-core debugging, real-time debug, on-chip tracing, multi-core processor
