Abstract:
1. A system for separating trace data output from a plurality of CPUs and/or busses, the system comprising: a low bandwidth trace information (LBTI) path configured to receive and process low bandwidth trace information from the plurality of CPUs and/or busses; a high bandwidth trace information (HBTI) path configured to receive and process high bandwidth trace information from the plurality of CPUs and/or busses; an on-chip trace buffer configured to record the high bandwidth trace information until a specific event trigger occurs; an off-chip trace interface configured to receive and output in parallel the low bandwidth trace information; a HBTI trace unit configured to process the high bandwidth trace information and generate a HBTI message; and a LBTI trace unit configured to process the low bandwidth trace information and generate a LBTI message.
