DYNAMIC POWER ALLOCATION BASED ON PHY POWER ESTIMATION

摘要

A system has a plurality of electronic components including a memory, a PHY coupled to the memory, and one or more other electronic components. Power consumed by the PHY is estimated during operation of the system. Estimating the power consumed by the PHY includes modeling the power consumed by the PHY as a linear function with respect to memory bandwidth. Available power for the PHY is determined based at least in part on the estimated power consumed by the PHY. At least a portion of the available power for the PHY is allocated to at least one of the one or more other components.
