Abstract
A method and device for correcting hardware errors without loss of resources while maintaining continuous operation of the computer system. Same method and device can be used for repair or addition of hardware parts to this system. The method and device can operate in a fault tolerant system which allows continuous service during the occurrence of a hardware failure or while parts are being repaired or added to the system. The method and device also use Hamming code to detect and correct all hardware failures, particularly a soft-soft uncorrectable error and a special uncorrectable error or a SUE.
