Also Available Domains Xilinx Vivado|Xilinx ISE

Project Code :TVPGFE87

Objective

The main aim of this work is to reduce the error rate in Booth multiplier by using Data Scaling Technology. The truncation errors in FWBMs are reduced by adding a circuit incorporating the proposed DST to them as well as an error-compensation circuit

Abstract

In this project, we propose a Data Scaling Technology (DST) for use in a low-error Fixed-Width Booth Multiplier (FWBM) to reduce truncation errors. The proposed DST uses the redundant bits of the multiplicand to more efficiently obtain bits for low-error FWBMs. More specifically, this method reduces the truncated partial products, which are used to estimate the compensation bias; however, the calculations in the FWBM are increased. The accuracy of the FWBM can be improved by adding the proposed DST circuit to it.

These results indicate that the use of the proposed DST increases the accuracy of low-error FWBMs with only a small area overhead.
