    • 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.
    • 用于提高具有同步数据流的计算机系统中的存储器带宽利用率的系统逻辑设备的实施例包括用于同步数据流的FIFO。 FIFO包括两个水印。 当FIFO的数据电平低于第一水印级别时,向存储器控制器发出低优先级请求。 如果FIFO的数据级别低于第二水印级别,则向存储器控制器发出高优先级的存储器请求。 低优先级存储器请求由存储器控制器分配给最低优先级。 高优先级请求由内存控制器分配最高优先级。 低优先级请求允许等时数据流从存储器检索少量数据,而不会不利地影响整个系统性能,而高优先级请求允许等时数据流在固定时间内从存储器检索更大量的数据,以确保 FIFO从来没有完全排水。

    • 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.
