摘要

This paper proposes a high speed and low complexity Segmented finite impulse response (FIR) filter using Variable size partitioning and Radix-2~r based MCM (VPRM). These variable size partitioning is classified into minimum size, optimum size and maximum size. The reason behind this partitioning approach is complexity reduction. For further reducing the computational complexity, the N bit input is segmented into N/2 bit inputs and then it is applied to Radix-2~r based MCM for partial product formation. These are obtained by performing the common sub sharing technique among the adjacent coefficients. The final output is the sum of shifted and zero appended output obtained from Partial product addition (PPA) block. The proposed Segmented FIR filter is designed and simulated in Xilinx ISE 14.2. The proposed Segmented FIR filter reduces the memory usage by 27.2, 25.96, 25.66, and 34.09% and energy consumption by 76.39, 75.74, 69.94, and 40.82% when compared with previous FIR filter designs such as FIR filter, FIR IPC, FIR IPC with pipelined CSA and FIR with Radix-2~r based MCM.
