    摘要: A 2/N mode clock generator that generates bus clock signals through the use of bus clock enable signals selecting bus clock pulses that are in phase and out of phase with a core clock signal. The clock generator maintains synchronization between the bus clock signal and the core clock signal so that they are always in a predetermined phase relationship.

    摘要: A hierarchical power control system for an integrated circuit may be integrated into a clocking system that includes a global clock generator, a clock distribution network in communication with the global clock generator and a plurality of functional unit blocks each in communication with the global clock generator. The hierarchical power control system may include a first power controller provided in a communication path between the global clock generator and the clock distribution network, and a plurality of second power controllers, one provided in each communication path between the clock distribution network and a functional unit block.
