High-speed microelectronic implementation of adaptive equalizers, encoders, and other associated signal processing algorithms is difficult, since the recursive portion of these algorithms contain nonlinear quantization operations. Examples of such algorithms include differential pulse code modulation (DPCM), adaptive DPCM (ADPCM), and differential feedback equalizers (DFEs). In the past, look-ahead computation techniques were successfully applied to create necessary concurrency in linear recursive and some nonlinear recursive operations (such as the add-compare-select operation). Novel computation approaches are presented, and the look-ahead technique is extended to pipeline the feedback loops containing finite-level quantizers. Approaches to pipeline piecewise linear recursive systems are also presented.
