Abstract
PURPOSE: To improve processing efficiency by extracting stored information on a program execution result right before the occurrence of a fault from one external memory unit in normal operation among several external memory units, and by immediately continuing the function.
CONSTITUTION: In case that CPU1a runs into trouble before executing program B, CPU2a, on detecting the fault of the party system, stores linkage information that normal CPU1a stores in external memory unit 2b and sets an entire function operation mode by switching. When a program performs processing B according to the schedule of CPU2a, the address of data of external memory unit 1c is obtained from the linkage information and from the address, data after processing A is extracted to perform processing B. consequently, stored information on the program execution result right before the occurrence of the fault is extracted from one external memory unit in normal operation and the function is continued immediately, so that the processing efficiency can be improved.
