Aerospace Instrument-Making Annotation << Back PERIODIC AND BIT-PARALLEL ALGORITHMS FOR INFORMATION PROCESSING FOR ON-BOARD CALCULATORS V.М. Khachumov, M.V. Khachumov 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 verifi cation 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. Keywords: periodic schedules, local algorithms, cycle alignment, bit-parallel circuits, mathematical functions, transformations, operands. Contacts: E-mail: khmike@inbox.ru Pp. 13-21.
