    • Some interface signals are selected from among signals of a plurality of different parallel interfaces, then being multiplexed onto a serial connection. A transmitter of a signal transmission system includes an interface-signal selector IFS, and a transfer programmer TP for issuing a control signal to instruct the selection from among the parallel interfaces. The transfer programmer TP implements the multiplexing of the selected interface signals in such a manner that the specification of the parallel interfaces is satisfied. Also, the transfer programmer TP changes, as occasion requires, the control signal to instruct which interfaces to select. This change allows the interface signals to be multiplexed onto the serial connection while dynamically changing the interface signals to be multiplexed.
    • 从多个不同的并行接口的信号中选择一些接口信号,然后被复用到串行连接上。 信号传输系统的发射机包括接口信号选择器IFS和用于发出控制信号以从并行接口指示选择的传输编程器TP。 传输编程器TP以满足并行接口的规范的方式实现所选接口信号的复用。 此外,转移编程器TP根据需要改变控制信号以指示哪些接口被选择。 该变化允许接口信号被多路复用到串行连接上,同时动态地改变要复用的接口信号。

    • For the relation between the first and second pass-transistor circuits (PT1, PT2), the output signal of the preceding-stage is supplied to the gate of the succeeding-stage, and for the relation between the second and third pass-transistor circuits (PT2, PT3), the output signal of the preceding-stage is supplied to the source-drain path of the succeeding-stage. The first pass-transistor circuit (PT1) receives on its first input node (In1) and second input node (In2) the first input signal and the second input signal that are logically independent from each other. This logic circuit requires a smaller number of transistors and is capable of reducing the power consumption and delay and accomplishing an intricate logic function.
