In order to meet the requirements in real time DSP applications MAC unit is required. The speed of the MAC unit determines the overall performance of the system. MAC unit basically consists of Multiplier, adder and an accumulator unit. In most of the cases floating point adder/subtractor and a multiplier are presented in IEEE-754 format for single precision format. In this research paper MAC unit is proposed. Various floating point multipliers are designed with the help of adders such as carry look ahead, carry save, carry skip and then their individual performance analysis is done on the basis of power, speed, and area.
