Dynamic Rescheduling of Tasks in Time Predictable Embedded Systems

The work concerns an approach to the multi-threading and multitasking problem. The main research objective of the time predictable real-time systems is identified. A brief summary of the related works is given. Idea of thread interleaving is described and the architecture of the proposed time predictable embedded system is presented. The solution of the dynamic interleave controller of threads (DICT) with dynamically modified (reconfigured) priorities of tasks (threads) is analyzed. The paper investigates the model of the system and gives its simulation results. The entire system is synthesized in the hardware structure. Some experiments with that emphasize advantages of the proposed hardware implementation.
