This paper presents two-dimensional (2-D) VLSI digital filter structures possessing various symmetries in the filter magnitude response. For this purpose, four Type-1 and four Type-2 power-efficient and cost-effective 2-D magnitude symmetry filter architectures possessing diagonal, fourfold rotational, quadrantal, and octagonal symmetries with reduced number of multipliers and one power-efficient...
In this paper, we propose two new two-dimensional (2-D) IIR and FIR filter architectures for 2-D transfer function with diagonal symmetry. The presented type-I structure with diagonal symmetry has the lowest number of multipliers, and zero latency without sacrificing the number of the delay elements. Importantly, the proposed type-II IIR filter possesses high speed, local broadcast, and the same number...
