MULTI-CORE MICROPROCESSOR CONFIGURATION DATA COMPRESSION AND DECOMPRESSION SYSTEM

摘要

An apparatus has a fuse array, a device programmer, and a plurality of cores. The fuse array is disposed on a die, where the fuse array comprises a plurality of semiconductor fuses. The device programmer is coupled to the fuse array and is configured to access the configuration data, to compress the configuration data to yield compressed configuration data, and to program the fuse array with the compressed configuration data. The plurality of cores is disposed separately on the die and is coupled to the fuse array, where each of the plurality of cores accesses and decompresses all of the compressed configuration data upon power-up/reset, for initialization of elements within the each of the plurality of cores.
