    摘要: Techniques for rate governing of a display data stream are described. In one embodiment, for example, an apparatus may comprise a processor circuit and a graphics management module comprising a differential analyzer. In some embodiments, the graphics management module may be operative on the processor circuit to determine a target display data transmission rate for one or more displays, determine, by the differential analyzer, an actual display data transmission rate for one or more display data packets based on the target display data transmission rate, transmit the one or more display data packets based on the actual display data transmission rate, and accumulate a difference between the actual display data transmission rate and the target display data transmission rate for the one or more display data packets. Other embodiments are described and claimed.

    摘要: Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques attempt to avoid visible glitches when switching from displaying a frame from a first source to displaying frames from a second source even though alignment is achieved by switching if frames that are to be displayed from the second source are similar to those displayed from the first source.

    摘要: A method and apparatus for managing overlay data requests are disclosed. One embodiment of an apparatus includes a request unit and a timer. A request is made by a graphics controller to the request unit for a line of overlay data. The request unit divides the request from the graphics controller into a series of smaller requests. The smaller requests are issued to a memory controller. Delays are inserted between each of the smaller requests in order to allow other system resources to more easily gain access to memory.

    摘要: An embodiment of a system logic device for improving memory bandwidth utilization in a computer system with an isochronous data stream includes a FIFO for the isochronous data stream. The FIFO includes two watermarks. When the data level of the FIFO falls below a first watermark level, a low priority request is issued to a memory controller. If the data level of the FIFO falls below a second watermark level, a high priority memory request is issued to the memory controller. The low priority memory request is assigned the lowest priority level by the memory controller. The high priority request is assigned the highest priority level by the memory controller. The low priority request allows the isochronous data stream to retrieve small amounts of data from memory without negatively impacting overall system performance while the high priority request allows the isochronous data stream to retrieve larger amounts of data from memory within a fixed time in order to ensure that the FIFO never completely drains.

    摘要: A dynamic priority controller monitors a level of data in a display engine buffer and compares the level of data in the display engine buffer to a plurality of thresholds including a first threshold and a second threshold. When the level of data in the display engine buffer is less than or equal to the first threshold, the dynamic priority controller increases a priority for processing display engine data in a communication channel. When the level of data in the display engine buffer is greater than or equal to the second threshold, the dynamic priority controller decreases the priority for processing the display engine data in the communication channel.
