Fast multiplication is very important in DSPs for convolution, Fourier transforms, etc. A fast method for multiplication based on ancient Indian Vedic mathematics is proposed in this paper. The whole of Vedic mathematics is based on 16 sutras (word formulae) and manifests a unified structure of mathematics. Among the various methods of multiplication in Vedic mathematics, Urdhava tiryakbhyam is discussed in detail. Urdhava tiryakbhyam is the general multiplication formula applicable to all cases of multiplication. The coding is done in VHDL (very high speed integrated circuit hardware description language) and synthesis is done using Xilinx ISE series. The combinational delay obtained after the synthesis is compared with normal multiplier. Further, this Vedic multiplier is used in matrix multiplication. This Vedic multiplier can bring great improvement in the DSP performance.
