The multiplier dominated applications such as digital signal processing, wireless communications, and computer applications, high speed multiplier designs has always been a primary requisite. Radix 8 it is necessary to compute 3X, X being the multiplicand. In order to avoid the penalty due to this calculation, we propose decoupling it from the product and considering 3X as an extra operation within the application’s Dataflow Graph (DFG). Experiments show that typically there is enough slack in the DFGs to do this without degrading the performance of the circuit, which permits the efficient deployment of radix 8 multipliers that do not calculate the 3X multiple. Higher radix should produce even larger reductions, especially in terms of area .we are perform the improving the proposed work using the carry look ahead adder this adder is very fast adder then the other adders, it improves the delay of the proposed work. results are shown in XILINX 14.3ISE.
