Abstract :
The paper presents an efficient implementation of an N-bit by N-bit combinational divider using the nonrestoring shift-subtract algorithm. A theoretical speed-up of 50% for an N/N-bit divider, compared to a merely truncated array implementation, is demonstrated. In practice, delay reduction of 25%-35% can easily be achieved with very little area overhead.
