Design of Pipelined Lattice IIR Digital Filters

Abstract

Lattice structures exhibit good finite word length properties. In some real-time applications, high speed is very crucial to the system performance along with finite word length effects. Although lattice filters can be pipelined but cut-set localization procedure, no sample rate increase can be achieved by that method. In this paper, a pipelining method in lattice digital filters is introduced. This pipelining method is based upon constrained IIR digital filter design method by which pipelined direct-form filters are designed. These direct-form filters are transformed to pipelined lattice digital filters. It is shown that the roundoff error and the number of multiply/add operations of the resulting pipelined lattice filters are smaller than those of the pipelined lattice filters obtained by applying look-ahead on direct-form nonpipelined digital filters.
