Implementation of distributed arithmetic-based symmetrical 2-D block finite impulse response filter architectures.

ABSTRACT: Background: This paper presents an efficient two-dimensional (2-D) finite impulse response (FIR) filter using block processing for two different symmetries. Architectures for a general filter (without symmetry) and two symmetrical filters (diagonal and quadrantal symmetry) are implemented. The proposed architectures need fewer multipliers because of the symmetry of the filter coefficients. Methods: A distributed arithmetic (DA)- based multiplication method is used in the proposed architecture. A dual-port memory-based lookup table (DP-MLUT) is used in the multiplication instead of lookup-table (LUT) to reduce the area and power of the FIR filter. The filter's throughput is increased by using block processing. Memory reuse and memory sharing methods are introduced, which reduc
