Registers and datapath multiplexers exist in most DSP datapaths. Although not performing computations, they are necessary for the dataflow control and they consume energy. This paper describes the nature of register and multiplexer energy consumption in modern low power CMOS processes, shows its strong dependence on architectural and layout design and provides practical design guidelines for micropower implementation
