A method for performing trace based measurement for a plurality of CPUs in parallel includes receiving a signal to perform a CPU parallel trace mode and enabling a parallel trace mode multiplexer to output all trace data, representing all data writes to the local memory, to a single observation unit. In one embodiment, the single observation unit is a processor observation block (POB), and in another embodiment, a bus observation block (BOB). If the single observation unit is a BOB, then the parallel trace mode multiplexer first routes the local memory data trace through a BOB adaptation layer to convert the CPU trace output data to data which is understood by the BOB. |
