Abstract:
The invention is a method and system for providing trace data in a pipelined data processor. Aspects of the invention including providing a trace pipeline in parallel to the execution pipeline, providing trace information on whether conditional instructions are complete or not, providing trace information on the interrupt status of the processor, replacing instructions in the processor with functionally equivalent instructions that also produce trace information and modifying the scheduling of instructions in the processor based on the occupancy of the trace output buffer.
