Fault suppression in a tree of Galois linear modules
J. M. Marver · Defense Technical Information Center (DTIC) · 1976
Galois logic design has application to fault tolerant technology. Test vectors and test sequences have been found which test all single and many multiple stuck-at faults in standard Galois linear modules with built-in parity check logic. A straightforward method provides fault detection, location, and suppression in galois linear modules arranged in a GF(2 the 4th power) tree network having single spares at each level. A single standard module with input multiplexers for test selection and spare selection can be replicated with very minimal additional logic to form a complete linear tree having a high degree of fault tolerance.
