Abstract
PURPOSE: To reduce greatly the chance for occurrence of the error, by performing the rewriting for recovery via the source data held by the service processor in case an error arises in the control storage which uses no error collection code.
CONSTITUTION: In case the data delivered from the control storage 2 receives an error detection through the parity detector 6 during operation of the CPU1, this information is transmitted to the interface 11 of the service processor SVP7 from the detector 6. The error occurrence address is transmitted to the address register 3 via the interface 11 in order to write the initial control storage data to the error occurrence address from the source data stored in the file 10. And at the same time, the initial control storage data is transmitted to the output register 5. Then the error occurrence data is rewritten to reduce greatly the chance for occurrence of the error.
