Abstract:
An apparatus comprising a cache comprising a plurality of cache entries, cache access circuitry responsive to a cache access request to perform, based on a target memory address associated with the cache access request, a cache lookup operation, tracking circuitry to track pending requests to modify cache entries of the cache, and prediction circuitry responsive to the cache access request to make a prediction of whether the pending requests tracked by the tracking circuitry include a pending request to modify a cache entry associated with the target memory address, wherein the cache access circuitry is responsive to the cache access request to determine, based on the prediction, whether to perform an additional lookup of the tracking circuitry. A method and a non-transitory computer-readable medium to store computer-readable code for fabrication of the apparatus are also provided.
