Continuous mutual extended processor self-test

Abstract:

A method for a continuous mutual extended processor self-test is provided. The method is implemented by a system including a plurality of cores. The system sets an operating condition for the continuous mutual extended processor self-test. An assist processor of the plurality of cores executes a test program that implements the continuous mutual extended processor self-test on a core under test of the plurality of cores. The system determines a pattern and a response during the test program execution and repeats the test program until the test program has finished or failed.
