Abstract

PURPOSE: To improve reliability and to attain econonmization in a communication controlling processor having a retrying function, by setting the contents of a current- address register in a next-address register when an error is detected during the execution of arithmetic.
CONSTITUTION: An error, if occurring in the arithmetic result data of arithemtic circuit 3, is detected by error detecting circuit 4, and the error occurrence is informed to retry control circuit 5. Retry controlling circuit 5 stops the arithmetic operation of the next instruction by arithmetic circuit 3 and inhibits the contents of next-address register 7 from being set in current-address register 8. Through retry start indication signal line 15, AND gate 10 is controlled to set the contents of current-address register 8 in next-address register 7. Further, the contents of next-address register 7 are set in main-memory address register 6, the instruction having caused the error is read out of main memory device 1 again and arithmetic circuit 3 executes the instruction.
