摘要： PURPOSE:To specify a device which is still powered on when the microprogram of a service processor indicates a break of power supply, by displaying its power-on line on the screen of the service processor if such a device exists. CONSTITUTION:A service processor SVP4 is coupled with a CPU2 through an SVP interface 103 and also connected to the CPU2, a main memory 1, an input/output controller 3, and an input/output device group 5 through a power supply controlling interface 104. The power supply controlling interface 104 consists of a command part for commands from the SVP and a state display part and the command part consists of the on-off line of a power source and the state display part consists of a complete line, a local line, an alarm line, and a power-on line. When some power source of the input/output device group 5 is still on even after an off command is sent out through the off line of the command part, that is displayed at the display part of the SVP through the power- on line to specify the corresponding device. Consequently, an input/output device is prevented from being held on forgetfully.
摘要翻译：目的：如果服务处理器的微程序指示电源断开，则通过在服务处理器的屏幕上显示其开机线，如果存在此类设备，则指定一个仍然通电的设备。构成：服务处理器SVP4通过SVP接口103与CPU2耦合，并且还通过电源控制接口104连接到CPU2，主存储器1，输入/输出控制器3和输入/输出设备组5 电源控制接口104包括用于来自SVP和状态显示部分的命令的命令部分，并且命令部分由电源的开 - 关线组成，并且状态显示部分由完整线，局部线路，报警线路和上电线路。当通过命令部分的离线发出关闭命令之后输入/输出设备组5的某些电源仍然打开时，通过电源在线显示在SVP的显示部分以指定相应的设备。因此，防止输入/输出装置被遗忘地保持。

摘要： PURPOSE:To improve data transfer efficiency and reduce the occupation time of transfer lines and so on, by compacting and transmitting data in case that data of the same contents is continuous. CONSTITUTION:Data transfer control unit 1 is constituted by four blocks of input data deciding part 100, frequency counting part 200, frequency comparing part 300, and data transmission selecting part 400, and before data transfer, data transfer start line 4 is set to ''1'' and required circuits of deciding part 100 and counting part 200 are initialized. Data given to data input line 2 is held in data holding circuits 101-103, and preceding data held in circuit 102 and the output of circuit 101 are compared with each other by comparing circuit 104, and data is held in circuit 102 in case of agreement between them, but counting part 200 and comparing part 300 are initialized in case of disagreement. Then, in case that data of the same contents is continuous, data is counted by counting part 200, and data on data output line 3 transmitted from selecting part 400 is compacted, thus improving data transmission efficiency and reducing the occupation time of transfer lines and so on.

摘要： PURPOSE:To make a typical operation possible with one touch by using a service processor to make the operation, which is performed typically according to a fixed procedure, into one frame. CONSTITUTION:Service processor 1, operation processing unit 2 and main storage 3 are connected by scan-in line 4, which sets data from processor 1 to an object register in operation processing unit 2 and a prescribed address of main storage 3, and scan-out line 5 which takes out data from the object register and the prescribed address. Only one frame of service processor is displayed on the screen once. Further, keyboard 13 is used as an input means for the operator.

摘要： PURPOSE:To make short the processing time of accessing to the extended memory, by providing the circuit controlling whether the memory in the range of addressing with the address line is accessed or the memory is accessed in excess of this range. CONSTITUTION:When the control program of the microcomputer system is stored in the memory extended in excess of the range possible for addressing, the address range of the fundamental memory addressible with the address information is clossified into the memory blocks B 1 and B 0, and the memory block B 2 of the extended section is corresponded to B 1. The block B 0 stores the controller determining either of which of B 1 or B 2 has the control and this controller controls the memory block selection circuit 4. Whether the output of the circuit 4 is made effective or ineffective is determined with 2 -bit in the memory address latch 5 to control the control circuit 8. Thus, the access processing time for the extended memories can be shortened.
