Abstract: A method and apparatus for processing a current macro-block of a current frame for motion compensation based on reference data from a reference frame using a sliding window cache to cache the reference data are disclosed. The method steps comprise processing a current sub-block of the current macro-block for motion compensation, determining the reference data for the current sub-block based on a reference sub-block in the reference frame, determining whether the reference data is within a sliding window, if the reference data is within the sliding window, checking for a valid tag corresponding to the reference data, responsive to the valid tag, retrieving the reference data from within the sliding window cache and processing the reference data for motion compensation.

Abstract: A method and apparatus are provided for scheduling data for transmission over a communication link shared by multiple applications operating on a host computer. The apparatus incorporates multiple storage components, with each storage component configured to store descriptors of data having one of multiple priorities. Each descriptor identifies a location (e.g., in host computer memory) of a portion of data to be included in a packet transmitted over the communication link. The apparatus services each storage component in turn to retrieve one or more descriptors, identify their associated data, retrieve the data and prepare it for transmission. Each storage component has an associated weight, which may be proportional to the priority of data represented by descriptors stored in the component. A storage component's weight may indicate a portion of the transmission bandwidth or a maximum amount of data that may be scheduled for transmission each time the component is serviced.
