АНОТАЦІЯ
Розглянуто побудови відмовостійких цифрових пристроїв і обчислювальних систем без використання модульної надлишковості. Для корекції сигналів застосовано спеціальний блок фіксації спотворених сигналів, схема вбудованого контролю за заздалегідь обраним надлишковим кодом, а також блок корекції сигналів. Блок фіксації спотворених сигналів реалізовано за методом логічного доповнення (ЛД), що дозволяє побудувати більшу кількість таких блоків з різними показниками складності технічної реалізації. Синтез відмовостійкого пристрою запропонованим методом дає змогу побудувати схему вбудованого контролю як початкового пристрою, так і блока ЛД в структурі блока фіксації спотворених сигналів. Це дозволяє серед багатьох способів реалізації відмовостійких пристроїв запропонованим методом обрати такий, що дозволить створити пристрій з найменшою структурною надлишковістю. Для створення схем вбудованого контролю можна використовувати різні надлишкові коди, у тому числі класичні та модифіковані коди з підсумовуванням. Запропоновано алгоритми синтезу блока фіксації спотворених сигналів і блок ЛД. Наведено результати експериментальних досліджень контрольних комбінаційних пристроїв з відомих наборів LG’91 і MCNC Benchmarks. Показано можливості даного методу при побудові відмовостійких цифрових пристроїв та обчислювальних систем.
