Abstract

The present invention is generally directed to method and apparatus for reducing power consumption in a processor through decreasing switching on the outputs of the processor. Switching reduction units are allocated at the outputs of a processor. The original outputs which include addresses, data and control signals of the processor and together with enable signals generated from a decode unit of the processor are inputs to the switching reduction units for executing the switching reduction function. The switching reduction unit contains at least one logic unit that reduces the number of switching when the enable signal is inactive. Implementing switching reduction units effectively reduces power consumption in a processor and results in a longer battery life.
