Title: System for managing multiple DMA connections between a peripheral device and a memory and performing real-time operations on data carried by a selected DMA connection

Abstract: Accordingly, the present invention provides a method and an apparatus of establishing multiple direct memory access connections between a peripheral and a main memory of a computer system. Each of the multiple direct memory access connection is managed in an improved manner such that one or more of the multiple direct memory access connections are non-real-time connections, but real-time operations may be performed on the data carried by the non-real time connections. In another aspect of the present invention, a driver may be implemented on the computer system to facilitate the establishment and maintenance of the multiple direct memory access connections. The present inventions reduce arbitration and system interrupt latencies and reduces the management burden of the direct memory access connections on a central processing unit of the computer system.
