ABSTRACT
Parallel MAC is frequently used in digital signal processing and video/graphics applications. The MAC provides high speed multiplication and multiplication with accumulative addition. This paper presents a combined process of multiplication and accumulation based on radix-4 & radix-8 booth encodings. In this Paper, we investigate the method of implementing the Parallel MAC with the smallest possible delay. Enhancing the speed of operation of the parallel MAC is a major design issue. This has been achieved by developing a new Radix-5 Kogge stone adder for parallel MAC.
