Abstract

PURPOSE:To reduce the overhead of the hardware and software in a central processing unit by constituting the system with a line group input output control means implementing data input output control to a line group comprising plural lines in the lump and a terminal input output control means controlling an input output data for each terminal equipment. CONSTITUTION:A line group input control means 8 of a line controller 7 has an input buffer in the unit of a line group and is allocated with a data storage area for each line belonging to the line group 10. A character inputted from each line is stored to a data storage area in the order of input and transfers the data inputted from the line group within a time for each determined time interval in advance to a terminal input control means 4 in the lump via a channel 6. A terminal output control means 5 has an output buffer in the unit of the line group and is allocated with a data storage area for each line belonging to the line group 10. The terminal output control means 5 transfers the data in the output buffer in the lump to the line group output control means 9 and outputs the data transferred in the lump in the unit of line group to each line.

なるという問題点があった。In the conventional line control method described above, when multiple full-duplex asynchronous terminals are connected to a central processing unit and characters are input from multiple terminals at the same time, an input/output interrupt is sent to the central processing unit for each character input/output. There was a problem that the control was continuous and the overhead was large.

る。jf! In FIG. 1, the line group input control means 8 of the line control device 7 has an input buffer for each line group, and the human buffer has a data storage area allocated to each line belonging to the line group 10. Characters input from each line are stored in the data storage area in the order of input. At predetermined time intervals (for example, 10 m5 ec), data input from the line group within that time is collectively transferred to the terminal input control means 4 via the channel 6. If data exceeding the data storage area is input within that time, the excess data will be discarded. The terminal input control means 4 transfers the data in the input buffer to each terminal input data key 5-2.
Transfer to. The output data of each terminal stays in the terminal output data queue 3. The terminal output control means 5 has an output buffer for each line group, and the output buffer is for each line group 10.
A data storage area is allocated for each line belonging to the network.

During each time period, the data accumulated in the terminal output data storage area 3 is stored in the data storage area for each line of the output buffer. When data exceeding the data storage area exists in the terminal output data storage area 3, only the data corresponding to the data storage area is stored in the data storage area. The terminal output control means 5 transfers the data in the output buffer all at once to the line group output control means 9.
