Claims
- 1. A method comprising:
establishing a node as a nominal root node, the nominal root node being a node with a right to transmit a packet on a bus; and dynamically changing the nominal root node responsive to a change in right to transmit on the bus.
- 2. An apparatus comprising:
a first port; and a physical layer (PHY) coupled to the first port that encodes a last packet of a subaction for transmission on a serial bus, the PHY arbitrating a next access to the serial bus and attaching a grant token to the last packet of the subaction to be transmitted out a highest priority port.
- 3. A system comprising:
a full duplex serial bus; and a plurality of nodes coupled together in a tree topology by the serial bus wherein a node transmitting a current packet is a nominal root node of the tree topology and wherein each other node repeatedly transmits current arbitration information toward the nominal root node.
