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. The inter-block transmission line is terminated by a resistor having substantially the same impedance as the interblock transmission line. The intra-block transmission lines are provided with a resistance element having a resistance substantially equal to a value derived by subtracting half of an impedance of the inter-block transmission line from an impedance of the intra-block transmission line, to lower signal amplitude and suppress reflections of a signal at branch points along the main interblock transmission line, thereby enabling a high-speed signal transfer.

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.
