Abstract: Digital FIR filter plays a significant role in today’s world of communication and computation. FIR filter is used in digital signal processing applications because of its stability, linear phase, low cost and simple structure. In MAC unit, both multiplication and accumulation functions are involved but the performances of MAC unit is mostly depends on dataflow structure of accumulation unit. Russian Peasant Multiplication (RPM) is the best multiplication algorithm which is based on "Multiply-divide" principle. In this study, multiplierless 12-tap FIR filter with and without optimized coefficients are compared with modified Russian Peasant Multiplier using 12-tap FIR filter in terms of area. The result analysis shows that proposed MRPM using MCSLA based 12-tap FIR filters are better than multiplierless 12-tap low pass FIR filter.
