Abstract
Techniques for improving overall data throughput in a computer system, especially during the playing of movies from CD-ROMs provides for a direct flow of data between the CD-ROM and the MPEG card, greatly reducing system memory usage and bus utilization. Control circuitry is responsive to signals from the CPU, which signals specify whether data from the CD-ROM can be sent directly to the MPEG decoder circuit or needs to be sent over the buses to the system memory. Accordingly, different transmission paths are used, depending on the attribute and destination of the data in order to reduce unnecessary data flow in the system and unnecessary consumption of system resources.
