Abstract

Un procesador de senales digitales para el procesamiento de una senal digital en respuesta a instrucciones de longitud variable. Almacenar una parte de lasinstrucciones con longitudes variables en lugares adyacentes dentro del espacio de la memoria yen el que el comienzo y el fin de las instrucciones tienenlugar entre los límites de palabras de memoria. Adicionalmente, otros aspectos adicionales de la presente se llevan a la práctica al contar con instruccionesque contengan cantidades variablesde fragmentos de instruccion. Cada fragmento de instruccion hace que se lleve a cabo una o más operaciones en particular, loque permite que se realicen multiples operaciones durante el ciclo de reloj. De esta manera, se llevan a cabo multiples operaciones durante caca ciclo de reloj, algo que reduce la cantidad total de ciclos de reloj necesarios para la realizacion de una tarea. Un método para realizar una operacion de multiplicacion dedoble precision que utiliza dicho procesador de senales digitales, se realiza por el uso de un banco de registro que cuenta con registros a los que puedenacceder al menos dos unidades de procesamiento. Esto hace posible que las multiples unidades de procesamiento puedan realizar multiples operaciones en ungrupode datos particular sin leer ni escribir los datos en y desde una memoria. Las unidades de procesamiento en la forma de realizacion ejemplar de la invencionincluyen una unidad aritmética logica (ALU) y una unidad de multiplicacion-acumulacion (MAC). Cuando se las combina con el uso de una arquitectura con busesmultiples, de instrucciones sumamente paralelas, o ambas, puede ponerse en práctica un aspecto adicional de la invencion, en el que se lleva a cabo unprocesamiento extremadamente encauzado y de multiples operaciones.
