Abstract
Technologies for local power gate (LPG) interfaces for power-aware operations are described. A processor includes locally-gated circuitry of a core, main core circuitry of the core, the main core, and local power gate (LPG) hardware. The LPG hardware is to power gate the locally-gated circuitry according to local power states of the LPG hardware. The main core decodes a first instruction of a set of instructions to perform a first power-aware operation of a specified length, including computing an execution code path for execution. The main core monitors a current local power state of the LPG hardware, selects one of the code paths based on the current local power state, the specified length, and a specified threshold, and issues a hint to the LPG hardware to power up the locally-gated circuitry and continues execution of the first power-aware operation without waiting for the locally-gated circuitry to be powered up.
