An apparatus includes a fuse array and a plurality of cores. The fuse array is programmed with compressed data. Each of the plurality of cores accesses the fuse array upon power-up/reset to read and decompress the compressed data, and to store decompressed data sets for one or more cache memories within the each of the plurality of cores in a stores that is coupled to the each of the plurality of cores. Each of the plurality of cores has reset logic and sleep logic. The reset logic employs the decompressed data sets to initialize the one or more cache memories upon power-up/reset. The sleep logic determines that power is restored following a power gating event, and subsequently accesses the stores to retrieve and employ the decompressed data sets to initialize the one or more caches following the power gating event. |
