On the Design Technique and VLSI Structure for a Multiplierless Quincuncial Interpolation Filter
무곱셈 대각 보간 필터의 설계 및 VLSI 구현에 관한 연구
Abstract
A huge amount of multiplications is required for 2-D filtering on the image data, making it difficult to implement a real-time quincuncial interpolator. In this paper, efficient design technique and VLSI structures for 2-D multipleierless filter are presented. In the filter design, by introducing an efficient scheme for discretizing the frequency response of the prototype filter, it is shown that a significant amount of the computational burden required in the conventional techniques, such as local search, branch and bound techniques, could be saved. In the case of 5
