ABSTRACT:
In a first embodiment, multi-speed concatenated packet strings are transmitted by a first node on a serial bus. To accommodate multi-speed packets, a speed signal is transmitted immediately prior to the packet. In a second embodiment, ACK-concatenation is used to allow a node to transmit a data packet immediately after transmitting an acknowledge signal on the bus. The data packet need not be related to the ACK packet. In a third embodiment, a node which receives a first data packet followed by a data end signal on a child port, concatenates a second data packet onto the first data packet during retransmission. The second data packet is also transmitted down the bus in the direction of the node which originally transmitted the first data packet.
