Abstract

See full text

A circuit includes a multi-bit flip flop, an integrated clock gating circuit connected to the multi-bit flip flop, and a control circuit connected to the integrated clock gating circuit and the multi-bit flip flop. The control circuit compares output data of the multi-bit flip flop corresponding to input data with the input data. The control circuit generates an enable signal based on comparing the output data of the multi-bit flip flop corresponding to the input data with the input data of the multi-bit flip flop. The control circuit provides the enable signal to the integrated clock gating circuit, wherein the integrated clock gating circuit provides, based on the enable signal, a clock signal to the multi-bit flip flop causing the multi-bit flip flop to toggle.
