ABSTRACT:
A switch for communicating short control messages and longer data messages. The control and data switch comprises separate resources for control messages and for data messages, while sharing communication links. Each input port of the switch has a separate control message input FIFO buffer and a data message input FIFO buffer. These buffers allow a control message to preempt a data message that is currently in progress over a link. If there are control message words waiting to be transmitted over the link, they are given prior over any data message words that are ready for transmission over the same link. Preemption of an ongoing data message by a control message takes place without disrupting the data message, other than delaying it.
