Abstract:
Aspects include computing devices, systems, and methods for implementing a cache memory access requests for compressed data using cache bank spreading. In an aspect, cache bank spreading may include determining whether the compressed data of the cache memory access fits on a single cache bank. In response to determining that the compressed data fits on a single cache bank, a cache bank spreading value may be calculated to replace/reinstate bank selection bits of the physical address for a cache memory of the cache memory access request that may be cleared during data compression. A cache bank spreading address in the physical space of the cache memory may include the physical address of the cache memory access request plus the reinstated bank selection bits. The cache bank spreading address may be used to read compressed data from or write compressed data to the cache memory device.
