In digital signal processing, the multiply–accumulate is the common and most important operation as it is used in number of computations. Multiplier–accumulator ( MAC unit) is the hardware unit which performs this operation. Multiply-Accumulate (MAC) unit has it’s major applications in MP, logic units and digital signal processors, as it is the unit which determines the delay of the overall system. MAC units are involved in designs such as Computation which are Non linear like FFT/IFFT, Discrete Cosine or wavelet Transform (DCT). A Large variety of techniques have been developed in algorithmic and structural levels to intensify the efficiency of the multiplier which is achieved by reducing the partial products and the approaches used in their addition. Multiply Accumulate (MAC) unit are used in developing for various high performance application. So, for reducing the power and area constraints the MAC unit will be implemented by using DADDA Multiplier algorithm. For this XILINX ISE 14.1 tool is used.

Keywords- MAC unit, DADDA Multiplier, Vedic Multiplier, Reversible logic gates, Kogge stone Adder.
