A data communication apparatus includes a router, first and second packet producers, and a penalizer. The router is directly connected to the first and second producers. The penalizer assesses penalties against each producer whenever that producer is serviced. The penalty value depends at least in part on an expected extent to which the first producer requires service. The penalizer then accumulates penalties against each producer.

Inverse weighted arbitration

An approach to data communication makes use of a protocol for encoding data on a serial link that provides both a run length limiting function and a frame marking function, while minimizing communication overhead over the data bearing portions of the signal, and while limiting latency introduced into the communication. In some examples, a single bit is added as a frame marker in such a way that a single bit frame marker also limits run length.

Link and physical coding sub-layer protocols

An approach to introducing adaptive routing into a communication approach for passing messages between nodes over links between the nodes includes forming virtual channels over the links of the system and defining a deterministic routing function over the virtual channels such that the deterministic routing function is deadlock free. Adaptive routing is then permitted at nodes using the existing virtual channels by introducing a constraint on the available virtual channels used to forward communication that arrives at a node for a particular destination. The constraint on the virtual channels is such that the adaptive system is also deadlock free.
