FPGA Implementation of Floating Point Reciprocator Using Binomial Expansion Method
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2013, Vol 1, Issue 7
Abstract
Floating-point support has become a mandatory feature of new micro processors due to the prevalence of business, technical, and recreational applications that use these operations. In these operations Floating-point division is generally regarded as a low frequency, high latency operation in typical floatingpoint applications. So due to this not much development had taken place in this field. But nowadays floating point divider has become indispensable and increasingly important in many scientific and signal processing applications. In this paper we implement floating point reciprocator for both single precision and double precision floating point numbers using FPGA. Here the implementation is based on the binomial expansion method. By comparing with previous works the modules occupy less area with a higher performance and less latency. The designs trade off either 1 unit in last-place (ulp) or 2 ulp of accuracy (for double or single precision respectively), without rounding, to obtain a better implementation.
