Application-level embedded communication tracer for many-core systems

Design verification and debugging with both software and hardware is ever challenging for many-core systems. We present the embedded tracer architecture for application-level communication. Not only can the trace information be optimized, but also the verification can be performed at the system level efficiently. The unified architecture consolidates the debugging flow at different abstraction levels, and facilitates the performance analysis of the entire system as well. The use-case study and experiments have justified the effectiveness of the proposed tracer architecture.
