    • PURPOSE:To extend substantially a bus line, by providing a bus controlling logic, a circuit which latches temporarily transfer data and a driver receiver to an adaptor device connected between a bus and an external input/output device. CONSTITUTION:A bus 6 of a system main body containing a CPU1, a main memory 2, an input/output device 3 and the bus 6 is connected to an external input/output controller 1 via an adaptor device 4. Data is read out of a device (not shown in the diagram) connected to the device 5 by a command given from CPU1 and stored temporarily in a built-in buffer. When the reading of the data is over, the data is put on an extended cable 7. Then an address controlling line 11 is turned on. The data is fetched by a driver receiver 13 and latched 9 and 10. If the capacity of the bus 6 is larger than the cable 7, the data is latched continuously until the capacity of the bus 6 is equivalent to the cable 7. Then a logical circuit 8 starts its operation to occupy the bus 6 and transfers the data to the memory 2. This process extends substantially the bus 6.
    • 目的:通过提供总线控制逻辑来实质上延长总线线路,将临时传送数据的电路和驱动器接收器连接到连接在总线和外部输入/输出设备之间的适配器设备。 构成:包含CPU1,主存储器2,输入/输出装置3和总线6的系统主体的总线6经由适配器装置4连接到外部输入/输出控制器1。 通过CPU1给出的命令连接到设备5并临时存储在内置缓冲器中的设备(图中未示出)。 当数据读取结束时,将数据放在扩展电缆7上。然后,地址控制线11被接通。 数据由驱动器接收器13取出并锁存9和10.如果总线6的电容大于电缆7,则数据被连续锁存,直到总线6的电容等于电缆7.然后a 逻辑电路8开始其操作以占用总线6并将数据传送到存储器2.该过程基本上延伸总线6。

    • PURPOSE: To process two CPUs completely independently and simultaneously and to speed up the transmission/reception of data by arranging required peripheral circuits between the two independent CPUs.
      CONSTITUTION: A transceiver 51 and a decoder 55 are connected between data buses 21W41 arranged between the CPUs 11, 31. An I/O address signal and a direction signal are inputted to the transceiver 51. In addition, latches 52, 53 are connected to the data bus 21 and an address bus 42. A driver 54 is connected to the address buses 22, 42 and a decoder 56 decodes the I/O address by a signal from the bus 22 and a control bus 23 and inputs the decoded signal to the latches 52, 53. Consequently, the CPUs 11, 31 can process programs completely independently and simultaneously in accordance with respective ROMs 12, 32 in the CPUs 11, 31 and also are available to access data at a high speed.
