Claim:
1. An apparatus for providing configuration data to an integrated circuit, the apparatus comprising: a device programmer, coupled to a semiconductor fuse array disposed on a die, configured to program said semiconductor fuse array with compressed configuration data for a plurality of cores disposed on said die; and a stores, coupled to said plurality of cores, said stores comprising a plurality of sub-stores that each correspond to each of said plurality of cores, wherein one of said plurality of cores is configured to access said semiconductor fuse array upon power-up/reset to read and decompress said compressed configuration data, and to store a plurality of decompressed configuration data sets for one or more cache memories within said each of said plurality of cores in said plurality of sub-stores, and wherein, following a power gating event, one of said each of said plurality of cores subsequently accesses a corresponding one of said each of said plurality of sub-stores to retrieve and employ said decompressed configuration data sets to initialize said one or more caches.
