摘要： In a printed board mounting method using a directional coupling bus for a high-speed data transfer, multi-bit data are transferred between nodes at a low cost. For this purpose, to transfer multi-bit data by directional coupling, a one-bit multi-coupling wiring network is vertically configured in a multilayered printed board. This minimizes the width of an area occupied by each bit along a wiring direction of the board to thereby implement a multi-bit configuration.

摘要： It is an object of the present invention to provide an active-line inserted/withdrawn functional circuit board, a data transfer system and a computer system which systems allow the functional circuit board to be inserted and withdrawn with signal lines remaining in an active state while achieving a high speed data-transfer of a bus, and the reliability to be enhanced by eliminating malfunctions which occur particularly during the insertion of a functional circuit board. The data transfer system or the computer system comprising: a functional circuit board having a functional circuit, a pre-charge resistor and a switching element connected in parallel to an input/output signal path of the functional circuit and a switching control means for controlling the conduction of the switching element through synchronization with a delayed clock signal resulting from delaying a bus clock signal for use in data transfers through the bus by a time shorter than a bus-clock cycle time of the bus clock signal; and a connector provided on an input/output end of the parallel connection of the pre-charge resistor and the switching element, whereby the functional circuit board can be inserted and withdrawn to and from the bus.

摘要： A signal transmitting circuit includes a circuit block having a driving circuit and an intra-block transmission line for transmitting a signal from the driving circuit, a circuit block having a receiving circuit and an intra-block transmission line for transmitting the signal to said receiving circuit, and a main interblock transmission line for propagating a signal between the driving and receiving circuit blocks.
