Project Code :TVPGTO624

Abstract

In this project, we propose a novel technique to multiply two unsigned binary numbers through a Segmentation based Approximate Multiplier (SAM). Approximate multiplier architectures face a fundamental challenge, i.e to reduce the area and delay significantly without introducing large inaccuracies. Almost all the existing approximate multipliers partition the input operands to exploit parallelism in the flow. The proposed design reduces the size of the Partial Products Matrix (PPM) in the order of n × (2n − 1) to a Reduced Partial Product Matrix (R-PPM) of the order 4 × 2n. Additionally, it also eliminates the extra hardware required for compression and rearrangement of partial products. µ-SAM, an optimized version of our basic design is also proposed along with this work. µ-SAM further minimizes the area and power consumption of the basic design.

NOTE: Without the concern of our team, please don't submit to the college. This Abstract varies based on student requirements.
