Improving Software Based Self - Testing for Cache Memories
Janusz S. Sosnowski · 2007
Testing cache memories within the computer system environment is based on using processor instructions, which involve cache operations intermixed with RAM memory accesses. Applying test patterns to the cache and checking its behavior needs sophisticated instruction sequences. We simplify these sequences by means of the available on-chip performance monitors as well as built-in on-line error detectors. This new method is compared with classical approaches.
