Abstract
A control circuit is configured to receive a stream of addresses associated with cache lookup requests resulting from execution of a workload by a data processing system. The control circuit includes a cache miss monitor and a cache hit monitor both coupled to a controller. The cache miss monitor determines a number of reoccurring misses as a difference between the number of addresses in the stream of addresses that miss in the cache and the number of such addresses that are unique. The cache hit monitor includes a moment circuit configured to determine first and second frequency moments addresses in the stream of addresses that hit in the cache. The controller controls the data processing system based on the number of reoccurring misses and the first and second frequency moments. A bypass mechanism of the cache may be controlled, for example.
