Abstract

PURPOSE:To grasp easily the cause of a fault, by providing an access stack in a data processing device and recording contents of the access stack to a predetermined fixed address area of a storage device when a fault occurs. CONSTITUTION:Each time a memory access controlling circuit 3 performs the memory access operation to a storage device 2, an access stack 9 can store the value of the address and contents of the request. If a fault occurs in a data processing device 1, an error detecting circuit 8 is operated to report the fault to a data processing/controlling circuit 7. The circuit 7 reads out access information from the access stack 9 to store it in a fault storage area 10 in parallel with the execution of the fault processing. In this case, the circuit 7 gives priority to access information in respect to the order of this fault recording so that contents of the access stack 9 for the fault recording to the storage device 2 through the controlling circuit 3 are not destructed similarly to the execution of a program.
