摘要： A high throughput memory access interface is provided. The interface includes features which provide higher data transfer rates between system memory and video/graphics or audio adapters than is possible using standard local bus architectures, such as PCI or ISA. The interface allows memory access requests to be performed in such a manner that only portions of an access request are required to be transmitted to the target device for certain bus transactions. Each access request includes command bits, address bits, and length bits. In the initiating device, each access request is separated into three segments, which are stored in separate registers in both the initiating device and the target device. Only the segment which contains the lowest order address bits and the length bits is required by the target device to initiate the bus transaction. Thus, if either of the other two segments has not changed since the previous access request, then such segment or segments are not transmitted to the target. If such segment or segments have changed since the previous access request, then they are provided to the target only for purposes of updating state in the target. Access requests may optionally be provided to the target on a separate port from the port used to transmit data in response to access requests.
摘要翻译：提供了高吞吐量的存储器访问接口。该接口包括在系统内存和视频/图形或音频适配器之间提供比使用标准本地总线架构（如PCI或ISA）可能提供更高数据传输速率的功能。该接口允许以这样的方式执行存储器访问请求，使得只有访问请求的一部分需要被发送到目标设备以用于某些总线事务。每个访问请求包括命令位，地址位和长度位。在发起设备中，每个访问请求被分成三个段，它们存储在起始设备和目标设备中的单独的寄存器中。目标设备只需要包含最低位地址位和长度位的段来启动总线事务。因此，如果其他两个段中的任何一个从先前的访问请求起没有改变，则这样的段或段不被发送到目标。如果这些片段或片段自从先前的访问请求以来已经改变，那么它们被提供给目标，仅用于更新目标中的状态。访问请求可以可选地在与用于响应于访问请求传输数据的端口的单独端口上提供给目标。

摘要： A method for communicating graphics device status information to a graphics driver. Status of a graphics device is checked to determine whether the graphics device is ready to process a next instruction. A location in cacheable memory accessible to a graphics driver is updated with the status. The graphics driver reads the status to determine when to generate the next instruction for processing by the graphics data. A first instruction to be forwarded to the graphics device is generated. A status in an operating register in the graphics device is updated indicating that an event is being monitored. The updating is performed in response to receipt of the first instruction by the graphics device. The status is written to a second cacheable location in system memory accessible to the graphics driver. A second instruction is generated by the graphics driver to provide a predetermined address and instruction completion data to the graphics device.
