The overall performance of any DSP system depends on the performance of the arithmetic unit. Multiplication is one of the pivotal operation in it. The speed and area of the multiplier is always a matter of concern for the better performance of any processor. In this paper a simple and efficient multiplier for 8-bit and 16-bit have been proposed. The proposed structure is a modified version of Bypass Zero, Feed A Directly (BZ-FAD) multiplier. It has been implemented on FPGA, Spartan 6 device. This structure has low power and area because of its uniqueness in using the proposed parallel prefix structure for addition of partial products in multiplier. The proposed multiplier lowers the switching activity by 55% and area by 64%.
