Uso de Estratégias de Multiplicação por Múltiplas Constantes para Implementação de Filtros Volterra

This work is focused on the development of a new effective strategy to implement Volterra filters using flexible or configurable hardware platforms such as field-programmable gate arrays (FPGAs). The proposed strategy is based on multiple-constant-multiplication (MCM) techniques, which utilize shifts, sums, and hardware reuse for effectively carrying out multiplications by constants. A transposed implementation for Volterra kernels is also introduced in this work aiming to further enhance the results obtained using MCM techniques. Experimental results demonstrate the effectiveness of the proposed strategy.
