摘要： Uncontested priority is provided to out-of-order data transfers over in-order data transfers on a data bus shared by a plurality of memory requesters. By always granting priority to out-of-order transfers such as deferred read data transfers over in-order transfers such as write and/or cache-to-cache data transfers, it is assured that no newer command or transaction ever negatively affects the latency of an older command or transaction.

摘要： An early return indication is used to notify a first communications interface, prior to a response being received from any of a plurality of sources coupled to a second communications interface, that the return data can be used by the first communications interface when it is received thereby from a source of the return data if the source has an exclusive copy of the return data. By doing so, the first communications interface can often prepare for forwarding the return data over its associated communication link such that the data can be forwarded with little or no latency once the data is retrieved from its source, and may be able to initiate the return of data over the communication link prior to all responses being received from the other sources. The early return indication may also serves as an early coherency indication in that the first communications interface is no longer required to wait for updating of a coherency directory to complete prior to forwarding the return data over the communication link.
摘要翻译：早期返回指示用于在从与第二通信接口耦合的多个源中的任一个接收到响应之前通知第一通信接口，使得第一通信接口在接收时可以由第一通信接口使用返回数据来自返回数据的源，如果源具有返回数据的排他副本。通过这样做，第一通信接口通常可以准备通过其相关联的通信链路转发返回数据，使得一旦数据从源中检索出来，数据可以很少或没有等待时间转发，并且可能能够启动返回在从其他来源接收到所有响应之前通过通信链路的数据。早期返回指示还可以用作早期一致性指示，因为在通过通信链路转发返回数据之前，第一通信接口不再需要等待更新相干性目录来完成。

摘要： In a shared memory architecture, early coherency indication is used to notify a communications interface, prior to the data for a memory request is returned, and prior to updating a coherency directory in response to the memory request, that the return data can be used by the communications interface when it is received thereby from a source of the return data. By doing so, the communications interface can often begin forwarding the return data over its associated communication link with little or no latency once the data is retrieved from its source. In addition, the communications interface is often no longer required to wait for updating of the coherency directory to complete prior to forwarding the return data over the communication link. As such, the overall latency for handling the memory request is typically reduced.
摘要翻译：在共享存储器架构中，早期一致性指示用于在返回存储器请求的数据之前以及在响应于存储器请求更新一致性目录之前通知通信接口，返回数据可以由当从返回数据的来源接收通信接口时。通过这样做，一旦数据从其源中检索，通信接口通常可以在几乎没有或没有延迟的情况下开始转发其相关联的通信链路上的返回数据。此外，通常不需要通信接口在通过通信链路转发返回数据之前等待更新相干性目录来完成。因此，处理存储器请求的总体延迟通常减少。

摘要： The distributed switch may include a plurality of chips (i.e., sub-switches) on a switch module. These sub-switches may receive from a computing device connected to a Tx/Rx port a multicast data frame (e.g., an Ethernet frame) that designates a plurality of different destinations. Instead of simply using one egress connection interface to forward the copies of the data frame to each of the destinations sequentially, the sub-switch may use a plurality of a connection interfaces to transfer copies of the multicast data frame simultaneously. The port that receives the multicast data frame can borrow the connection interfaces (and associated hardware such as buffers) assigned to these other ports to transmit copies of the multicast data frame simultaneously.
