Abstract

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