The extensive use of a Dynamic Distributed Arithmetic (DDA) algorithm eliminates the multiplier unit which requires more number of adders. Xilinx Spartan III devices is used for optimization. It is observed that up to 56.75% reduction in the number of slices, upto 75% reduction in flip flops and up to 53.2% reduction in the number of LUTs is achieved. The speed of the DDA is improved by 31%.]]>Ali, M. and A. Haj,2005Palnitkar, S.,1996Seals, R. and G. Whapshott,1997Smith, M.,1997Underwood, K.D. and K.S. Hemmert,2004Wirthlin, M.J.,2004Yokota, T., M.
