Abstract

PURPOSE:To realize a retrial exactly, by executing the initialized processing and the retrial of the contents of a tag part by means of accessing directly to a main memory device without using a local memory, when an error has been detected in a read-out data of the local memory. CONSTITUTION:In a data processing device for transferring the contents of a main memory device to a local memory 3 and processing them, data of a tag part 3-0 and a data part 3-1 of the memory are checked by parity checking circuits 8-0-8-15 and 9, and when an error has been detected, initializing and retrial of the memory 3 are started by a fault recovery control part 10. At the same time, a flag setting register 12 is set, coincidence of comparators 5-0-5-15 is negated, and a not-found detecting circuit 13 is turned on. In this way, access of a data from the local memory 3 is inhibited, the access is executed to the main memory device, and the processing is executed in accordance with a data obtained through a bus DATA.
