摘要
New processor structures for generalized stack filters are proposed, They can be implemented using different numbers of Boolean function units, The class of pipeline-parallel structures for generalized stack filters is simple and modular in structure, and suitable for VLSI implementation. Coder and decoder networks are developed for the mutual transform of binary-weighted and unary-weighted codes as the thresholding and addition units of the processors. The area-time complexity A . T of the proposed filters is O(k(3)) due to the feedback, instead of O(2(k)) for the threshold decomposition structure, where k is the number of bits for sample representation.
