The Concurrent Error-Detection Systems Organization Based on the Boolean Complement Method with the Preliminary Transformation of Operating Functions into Check Vectors of Berger Codes

The article describes a new way of concurrent error-detection (CED) systems organization using the Boolean complement method, which involves the use of pre-compression of signals from the diagnostic object using encoders of classical sum codes (Berger codes). Control of compressed signals is carried out using the constant-weight "1-out-of-4" code. In comparison with the known methods of the CED systems organization, it is possible to implement a self-checking digital device using one such circuit, and this significantly reduces the structural redundancy. The article suggests using the encoders of modified Berger codes with improved error detection characteristics as a compression scheme.
