Abstract: One embodiment of the present invention sets forth a crossbar unit that is coupled to a plurality of client subsystems. The crossbar unit is configured to transmit data packets between the client subsystems and includes a high-bandwidth channel and a narrow-bandwidth channel. The high-bandwidth channel is used for transmitting large data packets, while the narrow-bandwidth is used for transmitting smaller data packets. The transmission of data packets may be prioritized based on the source and destination clients as well as the type of data being transmitted. Further, the crossbar unit includes a buffer mechanism for buffering data packets received from source clients until those data packets can be received by the destination clients.

Abstract translation: 本发明的一个实施例提出了一种连接到多个客户端子系统的交叉开关单元。 交叉开关单元被配置为在客户端子系统之间传输数据分组，并且包括高带宽信道和窄带宽信道。 高带宽信道用于传输大数据包，而窄带用于传输较小的数据包。 可以基于源和目的地客户端以及正在发送的数据的类型来优先考虑数据分组的传输。 此外，交叉开关单元包括用于缓冲从源客户端接收到的数据分组的缓冲机构，直到目的地客户端可以接收到这些数据分组。
