Abstract

The avionics controlled parameters is a random function of time, the operation mode, the current state of the system and others. Urgent is the development of a time optimal of dynamic flow control, and manage the data in accordance with their priorities, as well as the synthesis of the corresponding controller external interrupts.
A functional-oriented external interrupt controller, operating according to the algorithm of dynamic ordering array of incoming applications according to their priorities is presented. The algorithm is based on the use of ordinal logic mathematical tool. It includes: the simultaneous comparison of the priorities and requests between a selection element with the highest priority; in case of equality of the priorities of two or more requests for the service selected request additional feature; at subsequent time intervals compared to the priorities still unserved requests.
Search function extreme element in the array is a function of infinite-valued logic. The procedure for opening the logical identifier quasimatrix large dimension with the primary indication of elements addresses adapted to the hardware implementation. The algorithm is characterized by uniformity and parallelism; high speed determined by the speed of the transient processes in elements; ability to work with arrays of direct and additional codes, which reduces lag.
Controller effectively ensure the absence of redundancy, high resolution and fast due to the simultaneous comparison of incoming request priorities.
