Abstract

PURPOSE: To improve the reliability of a system with the system prevented from being out of control when halting during its operation, by holding the state at that moment and before and by restarting the system right after a required treatment is done according to the cause.
CONSTITUTION: Three possible factors, a parity error, stalling and power disconnection, cause the computer system to stop. Once a parity error occurs, the contents of main memory unit 2 are stored in auxiliary memory unit 3. To all bits of main memory unit 2, "1"s are written first and read. When no parity error occurs at this time, "0"s are written to all bits of main memory unit 2 next and read. When no error occurs as well at this time, it is decided that this parity error has occurred by accident and when occurring, on the other hand, this is considered to be a perfect hardware error and the address and contents are outputted.
