Abstract

The purpose of the research is to reduce the time spent on processing information, contributing to an increase in the speed of a reconfigurable real-time system, by creating a methodology and an algorithm for distributing an array of computational tasks.

The research methods of the work are based on the definitions of set theory, graphs, probability theory and mathematical statistics. With their help, a mathematical model and a system of criteria for a reconfigurable real-time computing system, built on a wireless protocol, was created, which allows placing tasks according to the minimum-maximum time estimate. And also an algorithm for placing tasks in a computer complex is proposed, which allows increasing the performance of the system by reducing the time of data transfer.

As a result of the research, a method was developed for the distribution of computational tasks in a real-time reconfigurable computing system, which makes it possible to reduce the time of data transmission within the system, which increases the performance of the complex. A methodology for distributing computational tasks to individual processor modules has been compiled. The work of the proposed methods is simulated. And a system of criteria is proposed that describes the final state of a reconfigurable real-time computing system. As a result, the resulting system gave a gain in time of about 2.5 times. Placing connected problems in dynamic systems reduces the payoff coefficient linearly.

The resulting model can be used in distributed computing. The work of the proposed methods is simulated. Their analysis confirmed the increase in system performance as a whole.
