Abstract— The most area and power consuming arithmetic operation in high-performance circuits like Finite Impulse Response (FIR), multiplication is one. There are different types of multipliers to reducing the cost and effective parameters in FIR filter design. Among those this paper use truncated multiplier and modified Wallace multiplier in the fir design. The structural adders and delay elements occupies more area and consumes power in this form so it was a reason to forward the proposed method. In prior FIR filters design with low cost effective results will done by the faithfully rounded truncated multipliers with the carry save additions. In MCMAT design the low cost FIR filters within the best area and power results are implement in this paper by using the improved truncated methods. Along with that the proposed method modified Wallace multiplier based fir filter is also designed in this paper to make the fir filter design is suitable for low power applications.
