METHOD OF ORGANIZING SYSTEMS OF FUNCTIONAL CONTROL OF COMBINATION LOGIC SCHEMES BASED ON MODULE-WEIGHTED BERGER CODES
Annotation
A new method is proposed for organization of concurrent error detection system of combinational logical circuits with 100 % detection of single stuck-at faults on inner structure elements outputs. The method is based on partition of circuit outputs into the groups in which values of maximum two outputs may be distorted simultaneously. Module-weighted Berger codes with data vector lengths m = 2b, b = {2, 3, …} are used for the control. It is noted that module-weighted code with m = 4 is the most effective for this purpose: its generator has the simplest structure for which the self-checking property is easily ensured.
