Abstract :
This paper presents a power efficient dynamic chain adder based on a Data Dependent Precharging (DDP) algorithm. It suppresses spurious transitions due to the unconditional precharging of outputs during the `precharge´ mode. A 64-bit adder has been designed using the DDP dynamic chain architecture. Simulation results confirm that it operates at 270 MHz with 0.105 mW/MHz power consumption at 3.3 V supply. It reduces power by 36% without speed degradation
