摘要： The invention sets forth a crossbar unit that includes multiple virtual channels, each virtual channel being a logical flow of data within the crossbar unit. Arbitration logic coupled to source client subsystems is configured to select a virtual channel for transmitting a data request or a data packet to a destination client subsystem based on the type of the source client subsystem and/or the type of data request. Higher priority traffic is transmitted over virtual channels that are configured to transmit data without causing deadlocks and/or stalls. Lower priority traffic is transmitted over virtual channels that can be stalled.
摘要翻译：本发明提出了一种包括多个虚拟通道的交叉开关单元，每个虚拟通道是横杠单元内的逻辑数据流。耦合到源客户端子系统的仲裁逻辑被配置为基于源客户端子系统的类型和/或数据请求的类型来选择用于将数据请求或数据分组发送到目的地客户端子系统的虚拟信道。较高优先级的流量通过配置为传输数据而不引起死锁和/或停顿的虚拟通道进行传输。较低优先级的流量可以通过虚拟通道进行传输，可以停滞。

摘要： One embodiment of the invention sets forth a control crossbar unit that is designed to transmit control information from control information generators to destination components within the computer system. The control information may belong to various traffic paradigms, such as short-latency data traffic, narrow-width data traffic or broadcast data traffic. The physical connections within the control crossbar unit are categorized based on the different types of control information being transmitted through the control crossbar unit. The physical connections belong to the following categories: one-to-one (OTO) connections, one-to-many (OTM) connections, valid-to-one (VTO) connections, valid-to-many (VTM) connections wire-to-one (WTO) connections and wire-to-many (WTM) connections.
摘要翻译：本发明的一个实施例提出了一种控制交叉单元，其被设计成将控制信息从控制信息发生器传送到计算机系统内的目标组件。控制信息可能属于各种流量范例，例如短延迟数据流量，窄幅数据流量或广播数据流量。控制交叉单元内的物理连接基于通过控制交叉单元传输的不同类型的控制信息进行分类。物理连接属于以下类别：一对一（OTO）连接，一对多（OTM）连接，一对一（VTO）连接，有效对多（VTM）连接wire- 一对一（WTO）连接和线对多（WTM）连接。

摘要： One embodiment of the present invention sets forth a destination credit management unit (CMU) that is coupled to source clients and a destination client and manages the transmission of credits associated with the destination client to the source clients. The destination CMU receives credits from the destination client as memory spaces within the destination client free up and transmits the credits to source clients as credits are consumed by the source clients. When a data packet is received from a source client, the destination CMU returns a credit to the source client if a credit is available. If a credit is not available, then the destination CMU stalls the source client until a credit becomes available. Credits are transmitted to stalled source clients in the order in which the source clients were stalled.
摘要翻译：本发明的一个实施例提出了耦合到源客户端和目的地客户端的目的地信用管理单元（CMU），并且管理与目的地客户端相关联的信用与源客户端的传输。目的地CMU从目的地客户端接收信用，因为目的地客户端中的存储空间释放，并且将信用发送给源客户端，因为信源被源客户端消费。当从源客户端接收到数据包时，如果信用可用，则目的地CMU向源客户端返回信用。如果信用不可用，则目的地CMU停止源客户端，直到信用可用。信用按照源客户端停止的顺序传输到停滞的源客户端。
