Implementation of Double Precision Floating Point Multiplier on FPGA

A.Keerthi, K.V.Koteswararao

Multiplication is one of the common arithmetic operations in Digital Signal Processing(DSP) computations. The proposed design is an implementation of an IEEE-754 Double Precision Floating Point Multiplier, which is better when compared to a single precision multiplier[1] because of its wider dynamic ranges and accuracy. A Double Precision Multiplier is designed using Xilinx 12.4 ISE tool and the design verification was done on Xilinx Vertex-4 ML403 platform which handles overflow, underflow cases and Truncation mode. A Comprehensive simulation and analysis of multiplier output is done using Xilinx ISim simulator and a test bench is written to generate an input stimulus
