ABSTRACT:
An information processing system such as a microprocessor includes a processor core, a debug register circuit and a trace unit. The processor core is for processing information according to a program. The program includes a plurality of instructions for execution by the processor core. Each of the plurality of instructions has a corresponding address. The debug register circuit is coupled to the processor core. The debug register circuit includes a dedicated initiate trace breakpoint register coupled to receive and store an initiate trace address and a dedicated terminate trace breakpoint register coupled to receive and store a terminate trace address. The trace unit is coupled to the debug register circuit and the processor core. The trace unit initiates a program trace responsive to the program accessing the initiate trace address. The trace unit terminates the program trace responsive to the program accessing the terminate trace address. The program trace includes information regarding the execution of the program by the microprocessor.
