Abstract
A communication system includes a plurality of nodes connected in a daisy-chain via respective bus links configured for full duplex, synchronized communication. A node is configured to communicate a mailbox message with one or more connected nodes, the mailbox message having a flexible message size or flexible destination defined based on register access. A node includes a mailbox register configured to store a message header and one or more words of a current message for one or both of a transmit direction or a receive direction. The node includes a message buffer configured to store one or more messages including the current message for transmission or reception. The node includes a tunnel controller configured to communicate the current message from or to the message buffer as one or more mailbox packets with one or more of the connected nodes that participate in a mailbox tunnel over the daisy-chain.
