Abstract
En algunas modalidades, un filtro de múltiples etapas cuyas etapas del filtro bicuad se combinan con latencia entre las etapas, un sistema (por ejemplo, un codificador o decodificador de audio) que incluye tal filtro, y métodos para el filtrado bicuad de múltiples etapas. En las modalidades típicas, todas las etapas del filtro bicuad del filtro son operables de manera independiente para realizar el procesamiento de datos paralelizado completamente. En algunas modalidades, el filtro de múltiples etapas inventivo incluye una memoria intermedia, al menos dos etapas del filtro bicuad, y un controlador acoplado y configurado para imponer un flujo de instrucciones único a las etapas del filtro. Típicamente, el filtro de múltiples etapas está configurado para realizar el filtrado de múltiples etapas de un bloque de muestras de entrada en un solo bucle de procesamiento con iteración en un índice de la muestra, pero sin iteración sobre un índice de la etapa del filtro bicuadrático.
