PRINTED WIRING BOARD AND INFORMATION PROCESSING DEVICE

To ensure that, when laying a multipoint wiring that connects a plurality of memories, etc., signals are suitably transmitted without extending the total wiring length of the multipoint wiring.SOLUTION: Provided is a printed wiring board in which one transmission circuit 110 and N reception circuits 111-119 (N=integer 3 or greater) are connected by a multipoint wiring 102, with first to N-th branch points 102a-102e sequentially provided to the multipoint wiring which is connected at one end to the transmission circuit, the wiring branched off at each branch point 102a-102e being connected to the reception circuits 111-119, respectively. In this configuration, the wiring length TL0 from the connecting point of the transmission circuit to the first branch point is extended to be longer than the wiring length TL1 from the first branch point to the second branch point, and the wiring lengths TL2, TL3, TL4 between the adjacent branch points following the second branch point are reduced to be shorter than the wiring length TL1 from the first branch point to the second branch point.SELECTED DRAWING: Figure 3 【課題】複数のメモリなどを接続するマルチポイント配線を設ける場合に、マルチポイント配線の総配線長を長くすることなく、良好に信号を伝送できるようにする。【解決手段】１つの送信回路１１０とＮ個（Ｎは３以上の整数）の受信回路１１１～１１９とをマルチポイント配線１０２で接続したプリント配線板であって、一端が送信回路に接続されたマルチポイント配線に第１から第Ｎの分岐点１０２ａ～１０２ｅを順に設け、各分岐点１０２ａ～１０２ｅで分岐した配線を、それぞれの受信回路１１１～１１９に接続する。ここで、送信回路の接続点から第１の分岐点までの配線長ＴＬ０を、第１の分岐点から第２の分岐点までの配線長ＴＬ１よりも長くし、第２の分岐点以降の隣接した分岐点の間の配線長ＴＬ２，ＴＬ３，ＴＬ４を、第１の分岐点から第２の分岐点までの配線長ＴＬ１よりも短くした。【選択図】図３
