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。
