Self-Gating Flops for Dynamic Power Reduction

Abstract:

Systems or methods described herein may relate to latch-independent clock gating techniques to enable or disable an internal clock of an integrated circuit device. A programmable logic device includes a clock gating circuit that receives a clock signal and is latch independent. The clock gating circuit includes gating signal circuitry that generates a gating signal based on the clock signal and an enable signal. The clock gating circuit also includes a logic gate that generates a control signal based on the gating signal. The clock gating circuit also includes gated clock generation circuitry that generates a gated clock signal based on the clock signal and the control signal.
