Abstract
Disclosed is a computer in which an error caused by an intermittent failure is corrected by using a misprediction recovery mechanism which performs recovery processing if, after having predicted a branch destination of a branch instruction and speculatively executed an instruction at the predicted branch destination, it turns out that the branch prediction was wrong. The computer includes an error detection mechanism for detecting an error in logic operation of the computer, and an instruction re-execution mechanism for correcting an error caused by an intermittent failure when an error is detected by the error detection mechanism, by restoring the computer, using the misprediction recovery mechanism, to a state that existed before the occurrence of the error, and by re-executing a sequence of instructions including the instruction where the error is detected.
