Systematic Review on Multiply and Accumulate Unit (MAC) Architectures and Comparison with Various Multipliers

Abstract

The basic architecture of digital signal processing and digital image processing systems is the Multiply and Accumulate (Mac) architecture. Digital signal processing applications require Mac hardware with high speed and low power consumption as the main functions of DSPs, such as filtering and conversion, are used continuously. Macs also have applications for hardware and software. Floating-point arithmetic using the Mac architecture is more accurate but consumes more power and more silicon space. ieee-754 is a floating point algorithm that improves accuracy on Mac devices. In this systematic review, we are discussing various Mac architectures and their comparison with various multipliers.
