Abstract

PURPOSE:To exclude a process related to the control of transmission of data, by feeding the data given from a processor to an input/output device based on the priority order of a control table when access is requested from the processor. CONSTITUTION:When access requests are given from application programs P1-Pn, a processing part 5 executes an access controlling program 3 and writes the access requests in tables T1-T3 for each input and output. While the program 3 analyzes both a chain column CH and switch column SW to decide the data to be transmitted. For instance, the levels of matrix columns are set higher in order of Q0-Q2. In this case, the order of transmission of data B, A and C is informed to the part 5. Then the part 5 starts a control program 4, and data A-C in a memory 6 are fed to input/output devices I1-I3 in order of B, A and C. In such way, a program can be produced regardless of the input/output state when the application program is produced.

The types of applied program programs executed in the terminal control device are diverse depending on the needs of the user, and there are a large number of them. Generally, a relatively small-scale processing device (such as a Yita-shipu stomach separator) is incorporated as the control and processing means of the terminal control device. If access requests (for example, message sending) are made from a large number of application programs as described above to an input/output device connected to such a terminal control device, contention will occur. Conventionally, when creating an application program, it was necessary to create a program with consideration given to avoiding conflicts.
