Abstract:
A processor(s) performs a cache access to retrieve data, wherein the cache access by initiating a request that includes an address of a first address type. The cache access includes the processor(s) generating, based on historical data related to the address, a prediction for a location of the data in the cache that is a set identifier of a predicted cache set. The processor(s) concurrently perform a data access to the cache to retrieve sets in the cache. The processor(s) confirm(s) that the retrieved include the predicted cache set. The processor(s) utilize(s) the set identifier to select data from the predicted set.
