Abstract
An apparatus including a device programmer, a stores, and a plurality of cores. The device programmer programs a semiconductor fuse array with compressed configuration data for a plurality of cores disposed on a die. The stores has a plurality of sub-stores that each correspond to each of the plurality of cores, where one of the plurality of cores is configured to access the semiconductor fuse array upon power-up/reset to read and decompress the 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. The plurality of cores each has sleep logic that 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.
