Local interface error recovery for node-to-node transfers in mesh network on an integrated circuit (IC) and related methods

Abstract

A mesh network in an integrated circuit (IC) may transfer a data packet from a source node to a destination node through many node-to-node interfaces. When an error occurs, resetting the IC can have a significant performance impact. An IC including nodes interconnected in a mesh network may employ a transmit control circuit coupled to a transmit node and a receive control circuit coupled to a receive node to reinitialize interface circuits on both ends of a node-to-node interface in response to a detected error in either a transmit node or a receive node. This allows the IC to correct the error and continue to operate the rest of the IC while the node interface is reinitialized rather than resetting the entire IC. For example, errors that can trigger a node to be reinitialized may be in interface circuits, flow control circuits, or data packets.
