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： The present invention provides an information processing apparatus that may be designed in small and thin size and a small and thin CPU module that has a nigh heat releasing effect and is suitable therefor. The CPU module includes a processor, a connector to be electrically connected to the outside, a system control circuit for controlling transfer of a signal between the processor and the connector, and a printed board on which the processor, the connector and the system control circuit are mounted. The CPU module further provides a heat release plate one side of which is pasted with the printed board and the other side of which is substantially planar. The printed board has a cavity formed therein so that the processor may be fitted in the cavity in a bare-chip state. One side of the bare chip is jointed with the heat release plate.
