Dynamic resource allocation

摘要

A network interface device for providing an interface between a network and a data processing device, the network interface device having: a plurality of resources of different types for supporting the interface, and a bus interface for interfacing with the data processing device by means of a bus over which data can be sent by addressing to an address on the bus, the network interface device being arranged so that each resource may be addressed by a respective address on the bus. A data store stores mapping data defining pairings of resources between which communications are permitted.
