A host network controller for a network processor adapted to implement a Finite State Machine (FSM) for an operation adhering to a standardized communication protocol, wherein the finite state machine has fewer possible states than those defined for the operation in accordance with the standardized communication protocol. At least one register may be used to store the restricted set of state data. The network controller may also comprise a packet parser 207 adapted to parse a data packet and provide data to the at least one register based on the parsing result; and at least one action machine 208 adapted to implement one or more functions adhering to the standardized communication protocol based on the restricted set of state data stored in the at least one register. The at least one action machine may comprise a first action machine adapted to implement an operation state machine, a second action machine adapted to implement an instance identification parameter and a third action machine adapted to implement at least one channel filter each adhering to the standardized communication protocol. The states not included in the restricted set may include a transient state, a state that is not supported by the host network controller and a state wherein the host network controller is powered down. The standardized communication protocol may be the Network Controller-Sideband Interface (NC-SI) specification.
