PURPOSE:To arbitrarily execute the error processing without interrupting a current process by saving not only the process state of current processing but also error information indicating the occurrence of error in a saving means at the time of process switching due to interruption and performing the error processing of a data memory corresponding to error information. CONSTITUTION:An error information holding means 5 where error information indicating the occurrence of error in the access to the data memory is held and an error processing means 1b which performs the error processing of the data memory in accordance with error information held in the error information holding means 5 are provided. At the time of process switching due to interruption, the process state held in a process state holding means 1 and error information held in the error information holding means 5 are saved in a saving means (save register) 3 through a data line 106 and a switching circuit 4 to perform the error processing by an error processing means 1b. Thus, the error processing is arbitrarily executed without interrupting the current process. |
