PURPOSE:To ensure a highly efficient process of data and its control for a multiprogramming device, by connecting plural central processors to a single programming device. CONSTITUTION:The designation of numbers is set to a switch 4 of a programming device 2 for central processors 1-1 and 1-2 that request the working. These numbers and indication are converted into the proper codes through the device 2 and then transmitted to interfaces 5-1 and 5-2. The interfaces 5-1 and 5-2 inspects a coincidence between the signal received from the device 2 and the number set by the switch 6. When coincided, the corresponding indication is refered to significant to be transferred to the central processor. In such way, an access is given to the data between a single programming device and plural central processors. |
