  • System and method for synchronous processing of media data on an asynchronous processor
    Patent number: 7668982
    Abstract: The present invention provides a method and system for processing media data on a host processor. The method and system involve receiving media data, generating clocking signals, transferring media data to host processor buffers, generating media transfer done interrupts for each media data stream and generating an override interrupt to indicate to the host processor to process the media data. The override interrupt has high priority and effectively indicates to the host processor to forgo all other scheduled tasks and to start processing the media data.
