Annotation:
The article analyzes the characteristics of Hamming codes for error detection in data bits of code words in comparison with the characteristics of Berger codes, that is important for technical diagnostics tasks for automation and computing engineering systems test. The article covers the particularities of the application of the codes of interest for building the systems of concurrent error detection of arithmetic-logic devices. The article also describes the modifications of Hamming codes, associated with a decrease of the number of check bits. This directly affects the complexity of the concurrent error detection systems, but reduces the number of detectable errors in its operating outputs.

Key words:
concurrent error detection (CED) system; operational outputs; Hamming code; Berger code; Hamming code modification; modular code; data vectors; error in data vectors
