Abstract: Techniques for fast power gating of vector processors are described herein. In one embodiment, a method for power gating a vector processor comprises powering up a vector unit from an inactive state at approximately a boundary of a transmission time interval, and powering down the vector unit within the transmission time interval after the vector unit completes a task within the transmission time interval.
