AN APPROXIMATE MULTIPLIER BASED ON ROUNDING FOR USE IN HIGH-SPEED, ENERGY-EFFICIENT DSP PROGRAMMS

Abstract

This paper proposes a rounding-
based approximation multiplier (ROBA) that shifts
two numbers to appropriately multiply them.
Finding the best way to round a number using the
sign detector's data was the main focus of this
research. One hardware function for signed
multiplication of two integers, another for forum
signed multiplication of two integers, and a third for
sign sets that indicate exact, accurate, and
approximate multiplier values based on operands of
values a=b, a>b, and a barrel shifter that multiplies
the values according to the shifting formula to
obtain the approximate value with less delay than
various conventional multipliers can be used to
implement this research. Digital signal processing,
picture processing, and picture sharpening are some
of the applications for this approximation multiplier
with a rounding base. To use the ROBA multiplier,.
Approximation, reciprocating barrel applicator,
compressors, tolerance for error, multipliers.
