摘要： A bus system for carrying out data transfer between one bus master and a plurality of bus slaves. The bus system includes plural directional couplers which are formed by arranging respective parts of lines drawn from the bus slaves, without being in contact with, in the neighborhood of, and in parallel with a line drawn from the bus master. The line drawn from the bus master to a terminating resistance is wired to be folded. The directional couplers are further formed by arranging parts of the lines drawn from the bus slaves alternatively with respect to a first line part of the line drawn from the bus master ranging from the bus master to a fold of the line drawn from the bus master and with respect to a second line part of the line drawn from the bus master ranging from the fold to the terminating resistance.

摘要： Conventionally, wiring length occupied by a directional coupler decides intervals between modules connected to a bus, and those intervals can not be shortened furthermore. Accordingly, the intervals between modules are wide and high-density mounting is not possible. In the present invention, a directional coupler in a memory bus is formed by a leader line from a controller and a leader line from a memory chip and contained within a memory module. Accordingly, pitch between the modules can be reduced and high-density mounting can be realized.

摘要： A clock is located at a position close to a plurality of memory modules connected to a memory controller and located away from the controller, and wiring is carried out so that read access is preferential for transmission of read data. With respect to write data, a delay amount corresponding to a round-trip propagation delay time to each of the modules is measured and writing of the write data is carried out while maintaining a known time relationship between the clock and data. To measure round-trip reflection, lines are wired between the modules and a location detection circuit in a 1:1 relationship, and the circuit measures a time taken from a signal output time of a driver having the same impedance as that of the wired lines to a reflected-wave reception time of a hysteresis receiver.

摘要： A data transfer method is executed to transit a three-state transmitting circuit from a high-impedance state into a data output state, transmit a preamble (dummy data) onto a bus, and sequentially transmit the essential data. The shortening of a waveform caused in the first data piece after the transition from the high-impedance state into the data output state is executed against the preamble and no shortening of a waveform is not brought about in the essential data subsequent to the preamble. This makes it possible to exclude the limitation on speeding up the data transfer imposed by the shortening of the waveform.

摘要： A memory module bus system using a plurality of directional couplers to permit high-density packaging. A wiring line (main line) extending from a main controller and cooperating with a sub coupling line to form a directional coupler is open-ended or short-circuited to ensure that a forward wave and a reflection wave can be used to generate signals in opposite directions of the directional coupler. Memory modules are connected to opposite ends of the sub coupling line. The line length of the coupler can be half the pitch between the memory modules.

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： The number of steps for preparing a layout diagram of a circuit including a coupler, which is formed by arranging a main line and a stub line in parallel with each other, is reduced. A circuit diagram editor 1902 arranges a coupler symbol 100 stored in a component symbol storage section 1904 when the coupler is arranged in preparing a circuit diagram. A layout section 1935 of a layout diagram editor 1922 layouts two wirings constituting the coupler by use of circuit diagram information and coupler information in which a coupler length and a coupler interval are defined. An object extraction section 1937 of a wiring check section 1936 extracts components and wirings from the layout diagram, and passes these to a wiring checker 1938. At this time, the coupler is passed to the wiring checker as one component that cannot be decomposed no more. Therefore, an interval between two wirings constituting the coupler is not checked.
