HARDWARE PROFILING

According to one general aspect, an apparatus may include a trace control register, a first output path, and a second output path. The trace control register may be configured to receive one or more signals output by a combinatorial logic block. The trace control register may include a first register portion configured to capture the one or more signals. The trace control register may include a second register portion configured to capture whether an event occurred within the combinatorial logic block. The occurrence of the event is determined by at least a portion of the one or more signals having a predetermined state. The first output path configured to select between a plurality of captured signals provided by respective trace control registers. The second output path configured to output one or more captured events provided by one or more respective trace control registers.
