Abstract
A system and method for receiving high speed processor bus traces for study of computer system capacity and operation uses a small FIFO memory and skips unused bus cycles to avoid the requirement for memory speed to match the processor bus speed. Pipelined bus communications on the processor bus are aligned, in one mode, and in another, multiple instructions on split domain busses are aligned. In both cases a time stamp is obtained to match each processor word to a time of occurrence to facilitate study of the trace data.
