摘要：
Multi-state restore circuitry that allows storage elements of a power-managed functional block to be loaded when the functional block is repowered up so that the functional block is ready for operation virtually immediately after voltage ramp-up of the functional block. The multi-state restore circuitry includes a restore-state detector for determining which one of a plurality of restore states of the functional block is applicable to a particular repowering-up of the functional block. The multi-state restore circuitry also includes restore logic that loads the storage elements as a function of the restore state determined by the restore-state detector.
