Performance/Power Space Exploration for Binary64 Division Units
Abstract
The digit-recurrence division algorithm is used in several high-performance processors because
it provides good tradeoffs in terms of latency, area and power dissipation. In this work we
develop a minimally redundant radix-8 divider for binary64 (double-precision) aiming at
obtaining better energy efficiency in the performance-per-watt space. The results show that the
radix-8 divider, when compared to radix-4 and radix-16 units, requires less energy to complete a
division for high clock rates.
