Para esto, se describen los algoritmos Split-radix simétrico y asimétrico y se desarrolla toda su implementación en hardware. Los resultados de las pruebas incorporan también otros algoritmos conocidos como radix-2 lite, radix-2, radix-4 y pipelined. La evaluación comparativa del rendimiento de los algoritmos se realizó considerando los siguientes parámetros: la Relación Señal a Ruido de Cuantificación (SQNR), tiempo de procesamiento y la cantidad de recursos utilizados de la tarjeta Virtex-5 XUPV5-LX110T. Del análisis se obtiene que el algoritmo que presenta el mejor desempeño depende del parámetro analizado.]]></p></abstract>
