Abstract
Various aspects are described herein. In some aspects, the disclosure provides techniques for reducing latency in switching computing cores of a computing system between operating modes. Certain aspects provide a computing device including a plurality of computing cores, each configured to operate in any one of a plurality of operating modes. The computing device further includes a first voltage rail and a plurality of components, each associated with one of the computing cores. The computing device further includes a plurality of switches, each switch configured to selectively couple a corresponding one of the plurality of components to the first voltage rail. The computing device further includes a controller configured to determine a current operating mode of each of the plurality of computing cores and switch the plurality of switches at a first selected switching rate based on the determined current operating mode of each of the plurality of computing cores.
