Abstract

Un aparato para determinar una transformada de un bloque de datos codificados, el bloque de datos codificados comprende una pluralidad de elementos de datos. Un registro de entrada configurado para recibir una cantidad predeterminada de elementos de datos. A l menos un procesador de mariposa se acopla al registro de entrada y se configura para realizar al menos una operacion matematica en pares seleccionados de elementos de datos para producir una salida de elementos de datos procesados. Al menos un registro intermediario se acopla al procesador de mariposa y se configura para almacenar temporalmente los datos procesados. Un circuito de retroalimentacion se acopla al registro intermediario y al procesador de mariposa, y en donde si se habilita, se configura para transferir una primera porcion de elementos de datos procesados al procesador de mariposa apropiado para realizar operaciones matematicas, adicionales, y, en donde si se deshabilita, se configura para transferir una segunda porcion de elementos de datos procesados al menos a un registro de retencion.
