Reconfigurable DSP systems

Presents a new approach to the implementation of DSP structures that combines many of the benefits of ASIC-based systems with those of DSP processors. It is part of the work that the authors are engaged in to design and implement efficient DSP structures using hard-wired logic. The proposed technique utilises high density programmable logic devices (PLDs) to realise DSP structures that can be rapidly reconfigured in the field. A complete development system, consisting of a suite of computer-aided design tools, has been developed to provide the DSP designer with the means of generating hardware solutions in a short period of time. The work presented here covers all types of IIR and FIR digital filters, however, further work is continuing to include other DSP structures
