Concurrent error detaction of devices for extended galois fields elements processing
Binary codes of extended Galois fields elements are redundant, some of them never appear at the normal operation of the devices for processing of such field elements. Unused (forbidden) code combinations can be used to organize on-line testing (concurrent error detection) of the specified devices. The appearance of any forbidden combination will be a sign of error. The paper compares the various extended Galois fields with the possibility of on-line testing organization, the fields that best ensure its holding are determined.
