Abstract
System and method for monitoring a processor when it executes software code for a computer program. A register collects information regarding instructions executed by the processor, from the program counter; and a sampler, operatively connected to the register, asynchronously from the operation of the processor, samples contents of the register. The sampler may provide the samples to a host computer via a shift register in a JTAG port, and the host computer may provide a statistical record of the instructions executed by the processor.
