The paper brings forward an idea of multi-threaded computation synchronization based on the shared semaphored cache in the multi-core CPUs. It is dedicated to the implementation of multi-core PLC control, embedded solution or parallel computation of models described using hardware description languages. The shared semaphored cache is implemented as guarded memory cells within a dedicated section of the cache memory that is shared by multiple cores. This enables the cores to speed up the data exchange and seamlessly synchronize the computation. The idea has been verified by creating a multi-core system model using Verilog HDL. The simulation of task synchronization methods allows for proving the benefits of shared semaphored memory cells over standard synchronization methods. The proposed idea enhances the computation in the algorithms that consist of relatively short tasks that can be processed in parallel and requires fast synchronization mechanisms to avoid data race conditions.

A method for calculating the trajectory of a physical object that does not rely on explicitly setting the equation of motion is proposed. We analyze the problems and formulate requirements for the developed model. The choice of the motion algorithm is justified. The paper describes the technical part of the developed model and the logical structure of the program. The application contains the results of testing the system.

Zaproponowano metodę obliczania trajektorii obiektu fizycznego, która nie polega na jawnym wyznaczaniu równania ruchu. Przeanalizowano problemy i sformułowano wymagania dla opracowanego modelu. Uzasadniony jest wybór algorytmu ruchu. W pracy opisano część techniczną opracowanego modelu oraz strukturę logiczną programu. Aplikacja zawiera wyniki testowania systemu.
