ABSTRACT:
An electronic system comprises a plurality of components each having at least one communication node and being coupled together by communication links through the respective communication nodes so that the plurality of communication links and communication nodes form a bus which resembles an acyclic directed graph having established hierarchical parent-child relationships between adjacent nodes and a root node. Token passing style arbitration is implemented on the system, in one embodiment, in response to the root node sending out an unrequested bus grant, so that the node with the token has access to the bus.
