PURPOSE:To perform debugging with high efficiency for a state information storage device of an electronic computer, by recording the state of information on the kind and the generation time of an error. CONSTITUTION:When a signel logic in an error generating signal group 9 is set at 1, a write enable signal 7 is delivered by the next clock signal 5. Then the state information 2 is written to a stack 1, and at the same time the contents of the group 9 are written at other position of the same address. The logic of an error generating signal 6 is set at 1 after the contents of the group 9 are written to the stack 1. This prevents the output of the signal 7 and inhibits the working of an address forming circuit 4. Therefore it is possible to understand the progress of generation of an error and the kind and the generating time of the error by checking the record of the stack 1. |
