Abstract

Operacijski sustav za ugradbene sustave za rad u stvarnom vremenu s mješovitom razinom kritičnosti razvijen u ovom završnom radu je namijenjen za Cortex-R platformu. Cortex-R platforma je namijenjena za stroge sustave za rad u stvarnom vremenu i sustave s različitom razinom kritičnosti. Implementiran je OPA algoritam za statičku dodjelu prioriteta skupu zadataka s različitom razinom kritičnosti. Implementiran je statički pristup raspoređivanju zadataka SMC i adaptivni pristup raspoređivanju zadataka AMCrtb. Razvijeni operacijski sustav podržava upravljanje prekidima, memorijom i vremenom. Sustav je razvijen za ARM procesorsku arhitekturu. Sustav je testiran na TMS570LC43x pločici.

Abstract (english)

In this thesis real-time operating system for mixed criticality was developed for Cortex-R target platform. Cortex-R platform is intended for hard RTOS and mixed criticality systems. In this assignment OPA algorithm was implemented for static priority assignment for set of tasks with mixed criticality. Static task scheduling approach (SMC) was implemented, as well as the adaptive approach (AMCrtb). Operating system that was developed supports interrupt handling, memory management and time management. System was developed for ARM architecture and was tested on TMS570LC43x board.
