SYSTEM FOR PROCESSING MACHINE CHECK INTERRUPTION

摘要

Upon cocurrence of a fault the machine check interruption signal is output, which is detected and stored temporarily in a holding circuit. The interruption signal passes to a code register and to a selector. If the error indicated by the code register and decoder shows that continued operation of the hardware would not be reliable then a converter controls the selector to output an all-zeroes signal from a data store instead of the signal from the holding circuit. The all-zeroes signal acts on a machine check processing routine of a control routine to cause the processor to stop processing of the machine check interruption.
