A processor architecture and method are shown which involve a cache having heterogeneous cache sets. An address value of a data access request from a CPU is compared to all cache sets within the cache regardless of the type of data and the type of data access indicated by the CPU to create a unitary interface to the memory hierarchy of the architecture. Data is returned to the CPU from the cache set having the shortest line length of the cache sets containing the data corresponding to the address value of the data request. Modified data replaced in a cache set having a line length that is shorter than other cache sets is checked for matching data resident in the cache sets having longer lines and the matching data is replaced with the modified data. All the cache sets at the cache level of the memory hierarchy are accessed in parallel resulting in data being retrieved from the fastest memory source available, thereby improving memory performance. The unitary interface to a memory hierarchy having multiple cache sets maintains data coherency, simplifies code design and increases resilience to coding errors.
