Patent number: 11880310Abstract: A processor includes a cache having two or more test regions and a larger non-test region. The processor further includes a cache controller that applies different cache replacement policies to the different test regions of the cache, and a performance monitor that measures performance metrics for the different test regions, such as a cache hit rate at each test region.
