%X In this paper, we propose a new multiplier-and-accumulator (MAC) architecture for low power and high speed arithmetic. High speed and low power MAC units are required for applications of digital signal processing like Fast Fourier Transform, Finite Impulse Response filters, convolution etc. For improving the speed and reducing the dynamic power, there is a need to reduce the glitches (1 to 0 transition) and spikes (0 to 1 transition). Adder designed using spurious power suppression technique (SPST) avoids the unwanted glitches and spikes, thus minimizing the switching power dissipation and hence the dynamic power. Radix -2 modified booth algorithm reduces the number of partial products to half by grouping ofbits from the multiplier term, which improves the speed. The proposed radix-2 modified Booth algorithm MAC with SPST gives a factor of 5 less delay and 7% less power consumption as compared to array MAC.
