Abstract
A method and apparatus controls power consumption of at least one processor core by generating dynamic voltage and clock frequency scaling control information based on stochastic controller control parameters and workload performance error data. A processor core's voltage and clock frequency is varied based on the generated dynamic voltage and clock frequency scaling control information. In one example, a stochastic controller, is coupled to a dynamic voltage and clock frequency scaling (DVFS) circuit. The stochastic controller uses the stochastic controller control parameters and workload performance error data and generates the dynamic voltage and clock frequency scaling control information to control the DVFS circuit. Related methods are also disclosed.
