PURPOSE:To make detection of fault, picking-up of fault information, and restart of recovery processing execution possible in a system itself, by checking state of program by one another unless all of programs executed in time division are stopped because of fault. CONSTITUTION:When a fault occurs in an operating part 1, a program where the fault occurs wries fault information from a register 104 to a register 4. This information is outputted to a line 8 and is transmitted to a register 201 through a display line 6. A sequence generating logic circuit 202 selects a counter 3 for the purpose of executing programs, where bit of the register 201 corresponding to the program is fit to be turned off, in time division step by step. The program where the fault occurs is stopped because the bit of the register corresponding to this program is turned on. However, the execution of data processing is continued in other program. |
