SYSTEM FOR RECEIVING AN ISOCHRONOUS DATA STREAM AT A COMPUTER USING A MAIN MEMORY BUFFER

摘要

One embodiment of the present invention provides a system for receiving an isochronous stream of data (404) that buffers the isochronous stream of data within a main memory in a computer system. The system operates by receiving the isochronous stream of data within an interface within the computer system. The system demodulates this isochronous stream of data (406) to translate the isochronous stream of data from a modulated analog form into a digital form. Next, the system forwards the isochronous stream of data from the interface into a buffer (408) within the main memory (104) of the computer system without interrupting the processor (112). Next, the data passes from the buffer through a driver (109) that communicates with an application program (418) on the computer system.
