A tutorial on universal look-ahead algorithm for pipelining IIR filters

Abstract

The design of pipelined recursive filter with existing Look-ahead CLA and SLA scheme, A new LA scheme, referred to as DLA, is proposed for pipelined implementation of recursive Digital filters. It is established that in case of many recursive filters, DLA can provide equivalent and stable implementation with reduced pipeline delay and hardware, when compared with existing Look-Ahead schemes, comparison between DLA and SLA scheme.
