Title: Calculating device
Inventor: YAMAZAKI HIROMI
IPC: G06F11/34
Filed: 1994-02-16
Abstract: PURPOSE:To analyze a fault after use without adding a measuring instrument specially even for the purpose of use wherein a fault can not be analyzed during the use by providing a bus monitor means which monitors a bus transaction and a history storage means which stores a signal value on a bus. CONSTITUTION:If a fault occurs to one of processors, an abnormal signal detecting circuit 12 detects that and stops a memory control circuit 13 from sending a control signal. When the processor restarts operating after the fault occurrence, one of the processors sends a command to a bus transaction detecting circuit 11 through the bus 4 and then the memory control circuit 13 is stopped from sending the control signal. The contents of a nonvolatile memory 24 are not rewritten thereafter and information on the bus transaction right before the fault occurs is saved in the nonvolatile memory 24. Consequently, no special measuring instrument need not be added even for the purpose of use wherein a fault can not be analyzed during the use, and the fault information can be read out and analyzed afterward.
