Abstract: Disclosed herein are systems and techniques for slave-to-slave communication in a multi-node, daisy-chained network. Slave nodes may provide or receive upstream or downstream data directly to/from other slave nodes, without the need for data slots first to route through the master node.

Abstract: Disclosed herein are two-wire communication systems and applications thereof. In some embodiments, a slave node transceiver for low latency communication may include upstream transceiver circuitry to receive a first signal transmitted over a two-wire bus from an upstream device and to provide a second signal over the two-wire bus to the upstream device; downstream transceiver circuitry to provide a third signal downstream over the two-wire bus toward a downstream device and to receive a fourth signal over the two-wire bus from the downstream device; and clock circuitry to generate a clock signal at the slave node transceiver based on a preamble of a synchronization control frame in the first signal, wherein timing of the receipt and provision of signals over the two-wire bus by the node transceiver is based on the clock signal.

Abstract: In an example embodiment, a two-wire communication protocol engine manages control and data transmissions in a bi-directional, multi-node bus system where each node is connected over a twisted wire pair bus to another node. Some embodiments include a state machine that allows for synchronized updates of configuration data across the system, a distributed interrupt system, a synchronization pattern based on data coding used in the system, and data scrambling applied to a portion of the data transmitted over the twisted wire pair bus. The multi-node bus system comprises a master node and a plurality of slave nodes. The slave nodes can be powered over the twisted wire pair bus.
