Abstract

Un sistema de procesamiento de señales incluye un procesador de control de sistema (130), una tarjeta (180) de circuito integrado (CI), o tarjeta inteligente, para procesar el control de acceso a la memoria de sistema (100), y un circuito de interfaz (140) de tarjeta inteligente incluyendo un circuito de interfaz de acceso a memoria directa (100) para proveer acceso a a alta velocidad a la memoria del sistema (110). las transferencias de datos entre la tarjeta inteligente (180) y la memoria del sistema (110) se presentan vía el circuito de interfaz de tarjeta inteligente (140) antes de una transferencia y, después de que se completa una transferencia, procesa los datos transferidos que se almacenan en la memoria del sistema (110). El procesamiento mediante el controlador del sistema (160) no se requiere durante la transferencia para completar la transferencia. El circuito de interfaz (140) también filtra la corriente de datos transferidos revisando y generando porciones de paridad segun se requiere, y removiendo datos de control relacionados de la tarjeta inteligente de los datos que se almacenan en memoria.
