    摘要: Systems, methods, software products test a memory cache of a processor that includes a test engine (e.g., a BISTE). High level test source code is formulated to use routines in API source code that, when compiled into machine test code, interfaces with the test engine. The machine test code is executed with the processor to test the memory cache to detect one or more faulty memory blocks in the memory cache. If any of the faulty memory blocks are detected, the test engine is instructed, through the machine test code, to set one or more bits in registers to functionally replace the faulty memory blocks with redundant blocks of the memory cache.
