Abstract: Multiplication is one of the supreme operation in many high performance systems such as microprocessor, FIR filters, Digital Signal Processor, Image Processing etc. Since multiplication dominates the execution time of most operations, there is a huge demand in increasing the speed of the multipliers, which has been subject of interest over years. . Multiplier based on Vedic Mathematics is one of the fast and low power multiplier. This proposed Karatsuba-Ofman Pipelined Multiplier (KOPM) is designed mainly to optimize speed of the multiplier which is the major requirement in many applications. Karatsuba-Ofman algorithm  is employed to optimize the speed. Pipelining will enhance the performance of the multiplier. The multiplier is implemented for the low contrast image enhancement. This multiplier has been synthesized on Spartan3E.
