Realizations of a class of nonlinear filters using a bit-serial approach

A bit-serial architecture for a class of nonlinear filters is proposed. The class of filters contains all of the functions defined by stack filters, where rank-order and median filters and special cases. The digital realizations are simple and modular in structure, suitable for VLSI/LSI implementation. An experiment on an LSI implementation of rank-order function is described.<<ETX>>
