摘要
A method and system of managing data access in a shared memory cache of a processor are disclosed. The method includes probing one or more memory addresses that map to a subset of the shared memory cache and sensing a plurality of events in the one or more memory addresses. Cache utilization information is then obtained by reading a hardware performance counter of the processor. The hardware performance counter is incremented based on the occurrence of the plurality of events. Based upon the cache utilization information, an occurrence of one of the plurality of events is reduced.
