LOAD AWARE VOLTAGE REGULATOR AND DYNAMIC VOLTAGE AND FREQUENCY SCALING

摘要

A voltage regulator and/or associated circuitry provides an indication of average current consumed or drawn by a load, level and magnitude of transient events, and regulation efficiency. A dynamic voltage and frequency scaling governor makes use of the indication of average current consumed or drawn by the load, level and magnitude of transient events, and regulation efficiency to help optimize operation of the load, with respect to power and/or performance.

主权项

1. A system useful in provision of power to integrated circuitry forming a load, comprising:
a voltage regulator configured to provide regulated power to a load in accordance with a requested voltage level, the voltage regulator including circuitry for determining a signal indicative of average current provided to a load; a dynamic voltage and frequency scaling (DVFS) governor configured to determine a voltage to be applied to the load and a frequency of a clock signal to be used by circuitry of the load, the DVFS governor configured to adjust at least one of the voltage to be applied to the load and the frequency of the clock signal to be used by circuitry of the load based on the signal indicative of average current provided to the load.
