    • PROBLEM TO BE SOLVED: To provide a receiver with a voltage converting circuit, wherein miniaturization and small power consumption are attained. SOLUTION: The receiver is connected to a transmitter having a first mode wherein a signal including a first voltage and a reference voltage is output to a signal line and a second mode wherein the signal line is held at the reference voltage. The receiver includes a voltage converting circuit, a voltage converting circuit, a receiving circuit, and a voltage control circuit. The voltage converting circuit converts a source voltage into a first voltage and outputs it. The receiving circuit consumes substantially no electric power when the signal line is held at the reference voltage or when the signal line is held at an input driving voltage. The voltage control circuit inputs a first voltage output from a source voltage converting circuit as the driving voltage to the receiving circuit when the transmitter is in the first mode. When the transmitter is in the second mode, on the other hand, the voltage control circuit inputs the source voltage as the driving voltage to the receiving circuit and also stops the operation of the voltage converting circuit.

    • 要解决的问题:为接收机提供电压转换电路,其中实现小型化和小功率消耗。 解决方案:接收机连接到具有第一模式的发射机,其中包括第一电压和参考电压的信号被输出到信号线,以及第二模式,其中信号线保持在参考电压。 接收机包括电压转换电路,电压转换电路,接收电路和电压控制电路。 电压转换电路将源电压转换为第一电压并输出。 当信号线保持在参考电压时或当信号线保持在输入驱动电压时,接收电路基本上不消耗电力。 当发射机处于第一模式时,电压控制电路将从源电压转换电路输出的第一电压作为驱动电压输入到接收电路。 另一方面,当发射机处于第二模式时,电压控制电路将源电压作为驱动电压输入到接收电路,并且还停止电压转换电路的工作。 版权所有(C)2008,JPO&INPIT

    • PURPOSE:To decrease the time receiving a data and to attain transfer even if a transmission line is not quickened by providing a register between a receiving end and a serial/parallel converter to make the receiving end request transmission. CONSTITUTION:When the receiving end 2 transmits a transmission request 4 to a register 8 for transfer request of data, the register 8 transmits the data to the receiving end 2. Since the register 8 becomes idle, the register 8 outputs a transmission request signal 9 to a transmission end 1. The transmission end 1 transmits a parallel data to a parallel/serial converter 5, the data processed for serial processing enters the serial/parallel converter 6, where the data is processed for parallel processing and stored in the register 8. Thus, while the receiving end 2 processes the data from the register 8, the register 8 receives the next data.
    • 目的:通过在接收端和串行/并行转换器之间提供寄存器来实现接收端请求传输,即使传输线没有加快,也可以减少接收数据和实现传输的时间。 构成:当接收端2向寄存器8发送数据传送请求时,寄存器8向接收端2发送数据。由于寄存器8变空闲,寄存器8输出发送请求信号9 发送端1将并行数据发送到并行/串行转换器5,对串行处理进行处理的数据进入串行/并行转换器6,其中数据被处理用于并行处理并存储在寄存器8中 因此,当接收端2处理来自寄存器8的数据时,寄存器8接收下一个数据。
