Method and apparatus for reducing power consumption in a domino logic by reducing unnecessary toggles

摘要

A method and apparatus for reducing power consumption in a domino logic is provided. An input of the domino logic block has as an output of an upstream logic block. A first state, e.g. default or idle, of the output of the upstream logic block is determined. The an output of the domino logic block corresponding to the said first state is determined. A logic block is modified, such that the output of the domino logic block for the first state is the same as a precharge state of the output. This results in preventing the output of the domino logic block from toggling when the first state is the input to the domino logic block.
