Based on determining that the hardware profile exists, the power policy of the OS is updated for the launched application, and thereby, the driver updates the power state(s) of the hardware computing unit based on the new power policy.

Abstract: Methods and corresponding systems and apparatuses for saving power through selectively disabling clock signals in a systolic array are described. In some embodiments, a clock gate controller is operable to output a gated clock signal from which local clock signals of processing elements in the systolic array are derived. The gated clock signal corresponds to a root clock signal that is distributed through a clock distribution network or clock tree.

Disabling the gated clock signal disables the local clock signals along the entire branch, preventing any components that are clocked by those local clock signals from consuming power. Additional clock gate controllers can similarly be provided for other branches, including a branch associated with another column.
