Schedulability Analysis for Strictly Periodic Tasks in RTOS

Programming and Computer Software. 2018. Vol. 44. No. 3. P. 159–169.

Zelenova S. A., Zelenov S. V.

A new look at the problem of constructing a scheduler in the case of a group of strictly periodic tasks is proposed. The structure of the system of periods is represented in terms of graph theory. A criterion for the existence of a conflict-free schedule based on this representation is obtained, and generic schemes of algorithms for constructing such a schedule are described. The proposed approach is illustrated by building schedules for a number of strictly periodic tasks.

Design and architecture of real-time operating system

Mallachiev K. M., Pakulin N. V., Khoroshilov A. V., Proceedings of the Institute for System Programming of the RAS 2016 Vol. 28 No. 2 P. 181–192

Modern airliners such as Airbus A320, Boeing 787, and Russian MS-21 use so called Integrated Modular Avionics (IMA) architecture for airborne systems. This architecture is based on interconnection of devices and on-board computers by means of uniform real-time network. It allows significant reduction of cable usage, thus leading to reducing of takeoff weight of and airplane. IMA separates functions ...

Using modularization in embedded OS

Mallachiev K. A., Pakulin N. V., Khoroshilov A. V. et al., Proceedings of the Institute for System Programming of the RAS 2017 Vol. 29 No. 4 P. 283–294

Modern embedded OS are designed to be used in control solutions in various hardware contexts. Control computers may differ in the architecture of the CPU, the structure of communication channels, supported communication protocols, etc. Embedded OS are often statically configured to create an OS image, which intended to be executed on some specific control computer. ...

The human resource dimension of science-based technology transfer: lessons from Russian RTOs and innovative enterprises

Zaichenko S. A., The Journal of Technology Transfer 2018 Vol. 43 No. 2 P. 368–388

This study addresses ‘science-based’ technology transfer by research and technology organizations (RTO) whose mission is to combine intramural R&D and technology extension for industrial application. The paper is based on a unique database of Russian RTOs relating their science-based activity to technology transfer performance, on the one hand, and the contribution of R&D personnel sourced ...
