Abstract
A processor in accordance with the present invention includes memory that stores test data and control data. The processor also includes a test application that transmits the test data and the control data from the processor's memory to a test access port of the processor. The test access port then utilizes the test data and the control data to capture state data that defines at least one state of the processor while the processor is executing. This test data may be analyzed via conventional techniques to detect and isolate errors in the execution of the processor.
