ABSTRACT:
A method and structure for equipping a cache with information to enable the processor to track and report whether a given speculative access causes prefetches and/or pollutions of the cache. Two types of events are tracked in one of two different ways: first by counting/tracking prefetch operations, either globally or on a per instruction address basis and then by counting/tracking cache pollutions, either globally or on a per instruction address basis.
