Abstract
The described embodiments include a cache controller with a prediction mechanism in a cache. In the described embodiments, the prediction mechanism is configured to perform a lookup in each table in a hierarchy of lookup tables in parallel to determine if a memory request is predicted to be a hit in the cache, each table in the hierarchy comprising predictions whether memory requests to corresponding regions of a main memory will hit the cache, the corresponding regions of the main memory being smaller for tables lower in the hierarchy.
