Abstract

Some mechanisms for constructing periodic schedules and calculating mathematical functions for their application in airborne aircraft systems are proposed. A heuristic criterion for the quality of periodic schedules with a combination of information processing cycles is considered. The results of experimental veriﬁcation of the applicability of the criterion on local algorithms for multiple processing of information are presented. A set of bit-parallel computing schemes with an estimate of the number of summable operands is presented. The architecture of software and hardware in the on-board calculator is considered.

Предложены механизмы построения периодических расписаний работы и вычисления математических функций для их применения в бортовых системах летательных аппаратов. Рассмотрен эвристический критерий качества периодических расписаний с совмещением циклов обработки информации. Приведены результаты экспериментальной проверки применимости критерия на локальных алгоритмах многократной обработки информации. Представлен набор разрядно-параллельных вычислительных схем с оценкой числа суммируемых операндов. Рассмотрена архитектура программно-аппаратных средств в составе бортового вычислителя.
