Performance Analysis of Different Types of Adder for High Speed 32 Bit Multiply And Accumulate Unit

摘要

The addition and multiplication of two binary numbers is the fundamental and most often used arithmetic operation in microprocessors and digital signal processor. At the heart of data -path and addressing units in turn are arithmetic units such as comparators, adders and multipliers. Since multiplication dominates the execution time of mo st DSP algorithms, so there is a need of high speed multiply and accumulate (MAC) unit. Paper describes the analysis of speed and delay of different types of adder like carry -look ahead adder, carry skip adder, ripple carry adder and carry select adder for high speed 32 bit MAC unit
