    Abstract: An apparatus includes a fuse array and a stores. The fuse array is disposed on a die, and 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 decompresses the compressed configuration data, and stores 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, and where, following a power gating event, one of the each of the plurality of cores subsequently accesses a corresponding one of the each of the plurality of sub-stores to retrieve and employ the decompressed configuration data sets to initialize the caches.

    Abstract: An apparatus includes a fuse array, a stores, and a plurality of cores. The fuse array is programmed with compressed configuration data. The stores is for storage and access of decompressed configuration data sets. One of the plurality of cores accesses the fuse array upon power-up/reset to read and decompress the compressed configuration data, and to store the decompressed configuration data sets for one or more cache memories in the stores. Each of the plurality of cores includes reset logic and sleep logic. The reset logic is configured to employ the decompressed configuration data sets to initialize the one or more cache memories upon power-up/reset. The sleep logic is configured to determine that power is restored following a power gating event, and is configured to subsequently access the stores to retrieve and employ the decompressed configuration data sets to initialize the one or more caches following the power gating event.

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.
