Abstract
Apparatuses, computer readable mediums, and methods of processor unit testing using cache resident testing are disclosed. The method may include loading a test program in a cache on a chip comprising one or more processor units. The method may include the one or more processor units executing the test program to generate one or more results. The method may include redirecting a first memory reference to the cache, wherein the first memory reference is generated during the execution of the test program. The method may include determining whether the one or more generated results match one or more test results. The method may include redirecting a memory request to a memory location resident in the cache if the memory request includes a memory location not resident in the cache. The method may include redirecting a memory request to the cache if the memory request is not directed to the cache.
