  • Patent number: 7010712
    Abstract: A method synchronizes serial data stream output from a multiple-port system. The multiple-port system includes a plurality of port devices. The method includes (a) timing a serial data stream at each port device, the serial data stream including a series of data frames, (b) generating a framing signal at each port device, the framing signal indicating a boundary of the data frame in the serial data stream, (c) supplying the framing signal to a next port device, and (d) synchronizing, at each next port, the timing of the serial data stream in response to the supplied framing signal.

  • Patent number: 6970983
    Abstract: A multiple port system includes a plurality of port devices, each port device including a control register set, and a control bus coupled to the plurality of port devices. The control bus provides a control signal to each port device, and the control signal includes port address information and register address information. The control register set includes a set of registers responsive to the control signal if the port address information indicates the corresponding port device, and a designated register responsive to the control signal if the port address information indicates one of the plurality of the port devices and the register address information indicates the designated register.

  • Patent number: 4959833
    Abstract: A bus extender and data transmission method in which a continuous train of message frames of fixed size is sent along a dual serial link in both directions simultaneously. There is no handshaking between extenders unless a transmission error is detected. Message frames are constructed at a rate which is independent of serial link length and the bus data transfer rate. Each extender is divided into a bus handshake layer which sends and receives data and signals from a local bus, a management layer which continuously constructs message frames, responds to commands and receives and decodes incoming messages from a remote extender, and a transport layer. The transport layer has shift registers and encoders to receive messages from the management layer and transmit them over the serial link and has a memory to store up to 30 messages in the event of a retransmission request. The transport layer also receives messages from the serial link, checks for valid error-free messages and sends them to the management layer.
