  • Processing data using multiple levels of power control
    Patent number: 8161312
    Abstract: An apparatus and method is provided for data processing where power is automatically controlled with a feed back loop with the host processor based on the internal work load characterized by performance counters. The host automatically adjusts internal frequencies or voltage level to match the work load. The feedback loop allows tuning of frequency or voltage controlling power dissipation.
    Type: Grant
