Abstract
PURPOSE: To smooth the system processing, by measuring the using rate of the processor with the use rate monitor, causing the interruption signal if this is more than a given value and failures are taken place to the hardware, stopping the processor, and by changing over to other spare processor.
CONSTITUTION: The average use rate of the processor under operation is measured with the use rate measuring circuit 2 in the time distance designated with the time distance set register 3, and this is stored in the use rate storage register 4 with the trigger signal 11. On the other hand, the use rate register 5 is stored for the average use rate which is the reference in advance, and this is compared with the use rate of the register 4 at the comparison circuit 6. In this case, if the stored value of the register 4 is greater than that of the register 5, the signal 16 is caused and it is fed to the decision circuit 7 together with the failure generation signal 17, producing the stop and interruption signal. Thus, the processor is stopped and it is changed over to the spare unit.
