ABSTRACT:
A system and method for program counter and data tracing in a multi-issue processor is disclosed. Instructions are traced in program sequence order. In one embodiment instructions are traced in graduation order from a reorder buffer. The tracing mechanism of the present invention enables increased visibility into the hardware and software state of the processor core.
