Abstract

Abstract : Focused on the issue that division is complex and needs a long latency to compute, a method to design the unit of high‐performance Floating‐point (FP) divider based on Goldschmidt algorithm was proposed. Bipartite reciprocal tables were adopted to obtain initial value of iteration with area‐saving, and parallel multipliers were employed in the iteration unit to reduce latency. FP divider to support pipeline execution with the control of state machine is presented to increase the throughput. The design was implemented in Digital signal process (DSP) chip by sharing the existed multipliers.
