Objective
The main aim of this work is to reduce the power in multiplier by using different 4:2 compressors designs
Abstract
In this project, three novel approximate 4-2
compressors are proposed and utilized in 8-bit multipliers. Meanwhile, an
error-correcting module (ECM) is presented to promote the error performance of
approximate multiplier with the proposed 4-2 compressors. Approximate computing
is utilized in some digital signal processing applications which are inherent error
tolerant circuits. The approximate arithmetic blocks are utilized in them to optimize
performance of these circuits. Multiplier is basic in computer arithmetic blocks.
Moreover, the 4-2 compressors are widely employed in the parallel multipliers
to accelerate the compression process of partial products. In this project, the
number of the approximate 4-2 compressor’s outputs is innovatively reduced to
one, which brings further improvements in the energy-efficiency. Compared with
the exact 4-2 compressors, the simulation results indicate that the proposed
approximate compressors UCAC1, UCAC2, UCAC3 achieve optimized delay, power and
area, respectively. And the utilization of these proposed compressors in 8-bit
multipliers brings reduction of power consumption.
