Abstract

PURPOSE:To prevent the lowering of the processing efficiency, by adding an index called ''discrimination frequency'' to processing request information and not accepting processig request information requiring the program switching work until the discrimination frequency becomes a certain value. CONSTITUTION:A discriminating circuit 14 discriminates the discrimination frequency included transferred processing request information; and if the discrimination frequency is lower than a certain value (n), the circuit 14 transfers this information to a discriminating circuit 17; and otherwise, the circuit 14 transfers this information to a register 16 to set a program classification included in this processing request information to a status register 18. The discriminating circuit 17 compares the program classification included in processing request information with the program classification indicated by the status register 18; and when they coincide with each other, processing request information is transferred to a register 16; and otherwise, the circuit 17 transfers this information to an operating circuit 20. The operating circuit 20 counts up the discrimination frequency included in processing request information and transfers this information to a register 15. The register 15 transfers inputted processing request information to a terminal station 3.
