摘要： System and method of memory utilization in a computer system are described. In one embodiment, the method comprises, responsive to receipt of a DMA transaction from an entity, determining whether a number of pending memory requests for the entity is less than a prefetch limit therefor; and responsive to a determination that the number of pending memory requests for the entity is less than the prefetch limit therefor, issuing a new memory request comprising a portion of the received DMA transaction.
摘要翻译：描述了计算机系统中的内存利用的系统和方法。在一个实施例中，该方法包括：响应于从实体接收到DMA事务，确定对于该实体的多个未决存储器请求是否小于其预取限制; 并且响应于确定所述实体的未决存储器请求的数量小于其预取限制，发出包括所接收的DMA事务的一部分的新的存储器请求。

摘要： System and method of memory utilization in a computer system are described. In one embodiment, the method comprises, responsive to receipt of a DMA transaction from an entity, determining whether a memory request comprising a cache line-sized portion of the DMA transaction is speculative; and responsive to a determination that the memory request is not speculative, ensuring that a prefetch lock indicator of a cache line of a cache associated with the memory request is in a locked condition, thereby preventing a cache replacement algorithm (“CRA”) from flushing the associated cache line.

摘要： A method of memory space allocation, performed within a coherent memory of a computer system, for allocating a line of the memory to a device using an ownership-only command, which transfers ownership of the line of memory without transferring the data contained within the line. After receiving the command, the memory then determines if the line was previously allocated to a second device using a conventional read command, the memory sends a flush command to the second device, and retrieves the contents of the line from the second device. After retrieving the contents of the line, or if the second device used the ownership-only command, the memory sends an ownership acknowledgment for the line to the first device, receives replacement data for the line from the first device, and then releases ownership of the line.
摘要翻译：一种在计算机系统的相干存储器内执行的存储器空间分配的方法，用于使用所有权命令将存储器的一行分配给设备，该命令在不传输包含在该行内的数据的情况下传送存储器行的所有权。在接收到命令之后，存储器然后使用常规读取命令确定该行是否先前被分配给第二设备，该存储器向第二设备发送刷新命令，并且从该第二设备检索该行的内容。在检索线路的内容之后，或者如果第二设备使用所有权命令，则内存向该第一设备发送该线路的所有权确认，从第一设备接收该线路的替换数据，然后释放所有权线。

摘要： A computing device having partitions, and a method of communicating between partitions, are disclosed wherein at least one partition comprises: at least one register substantially always accessible to other partitions and capable of defining an address area; at least one address area that may be accessible to other partitions and is capable of being defined by the at least one register; and address areas other than the at least one accessible address area that are not accessible to other partitions. A method of processing interrupts comprising receiving an interrupt, assessing the origin of the interrupt, accepting, rejecting, or further assessing the interrupt, depending on its origin, when further assessing the interrupt, accepting or rejecting the interrupt depending on its contents, and forwarding accepted interrupts but not rejected interrupts to a target processor, and a device carrying out that method are also disclosed.
