This document discusses the design of finite impulse response (FIR) filters using multiple constant multiplication/accumulation (MCMA) technique to reduce hardware resources and cost. It proposes using truncated multipliers in the MCMA module to remove unnecessary partial product bits without affecting output precision. The filter coefficients are quantized with unequal word lengths using non-uniform quantization to minimize bit widths and reduce hardware cost while maintaining frequency response specifications. Simulation results show that direct-form FIR filters using the proposed truncated MCMA technique achieve lower area and power consumption than transposed-form implementations.
