Claim 6:
7. The processing system of claim 1, wherein the main processing core further comprises a main trace circuit having a trace input coupled to a trace bus and a trace output coupled to the trace bus, wherein the shadow processing core further comprises a shadow trace circuit having a trace input coupled to the trace bus, the processing system further comprising a trace bus synchronizer circuit having a trace input configured to receive trace input data in synchrony with a trace clock, and an output coupled to the trace bus, wherein the trace bus synchronizer circuit is configured to provide synchronized trace data in synchrony with the core clock to the trace bus based on the input trace data, wherein the main and shadow trace circuits are configured to receive the synchronized trace data in synchrony with the core clock from the trace bus, and wherein the trace clock is asynchronous with respect to the core clock.
