Abstract: Techniques are disclosed relating to a split communications fabric topology. In some embodiments, an apparatus includes a communications fabric structure with multiple fabric units. The fabric units may be configured to arbitrate among control packets of different messages. In some embodiments, a processing element is configured to generate a message that includes a control packet and one or more data packets. In some embodiments, the processing element is configured to transmit the control packet to a destination processing element (e.g., a memory controller) via the communications fabric structure and transmit the data packets to a data buffer. In some embodiments, the destination processing element is configured to retrieve the data packets from the data buffer in response to receiving the control packet via the hierarchical fabric structure. In these embodiments, bypassing the fabric structure for data packets may reduce power consumption.

Abstract translation: 公开了关于分离通信结构拓扑的技术。 在一些实施例中，装置包括具有多个织物单元的通信结构结构。 结构单元可以被配置为在不同消息的控制分组之间进行仲裁。 在一些实施例中，处理元件被配置为生成包括控制分组和一个或多个数据分组的消息。 在一些实施例中，处理元件被配置为经由通信结构结构将控制分组发送到目的地处理元件（例如，存储器控制器），并将数据分组发送到数据缓冲器。 在一些实施例中，目的地处理元件被配置为响应于经由分层结构结构接收控制分组而从数据缓冲器中检索数据分组。 在这些实施例中，绕过用于数据分组的结构结构可能会降低功耗。

Abstract: In some embodiments, a system includes a memory system, plurality of computing devices, and plurality of queues. The plurality of computing devices perform actions dependent on data stored at the memory device, where traffic between the plurality of computing devices and the memory device has at least a first priority level and a second priority level. The first priority level is higher than the second priority level. The plurality of queues pass data between the memory device and the plurality of computing devices. A particular queue allocates a first portion of the particular queue to traffic having the first priority level and allocates a second portion of the particular queue to traffic having the first priority level and to traffic having the second priority level.
