Abstract: An electronic system interconnect. The interconnect comprises a first node and a second node coupled to the first node. The interconnect is initially configured to include the first and second nodes. A third node is added to the interconnect after the interconnect is initially configured, and the first node responds to the addition of the third node by initiating a new connect handshake with the third node. The first node begins by transmitting a first signal to the third node. The first node signals that the third node has been added to the interconnect if the third node responds to the first signal by transmitting a second signal. The first node causes the interconnect to be reconfigured if the third node transmits a third signal in response to receiving the first signal.

Abstract: An interface device for a point-to-point connected serial bus in which bus clock and bus data transmissions on the bus cease between transmissions of packets of data, includes a low latency resynchronizing circuit and an end of packet detector which is independent of control data within the packet. The resynchronizer is based on an interface which receives bus data and bus clock from a transmission of a packet on the bus. A circular input buffer stores bus data received from the bus in data locations indicated by an input pointer in response to the bus clock. An input pointer generator supplies the input pointers to the input buffer in a circular sequence, beginning in a particular location during a first bus clock in a packet. An output selector supplies bus data from one of the N data locations in the input buffer to the selector output in response to an output pointer and in response to the local clock.
