Fast radix 2K dividers for FPGAs
Gustavo D. Sutter, Jean Pierre Deschamps · 2009
In this paper we present radix r = 2kdivider for fixed-point operands. The divider divides in a radix r = 2k, producing k bits at each iteration. The proposed digit recurrence algorithm has two different architectures, a first one for general hardware implementation, and the second one is optimized for configurable logic (FPGAs). Results show a speedup greater to three times respect to a classical non-restoring division implemented in Xilinx Devices. Additionally a throughput-latency-area comparison of pipelined and sequential dividers implementation is disclosed.
