Original Abstract

This paper takes a brief look into fault tolerant techniques and presents a proposal of hardware hard real-time OS scheduler monitor. Purpose of the new proposal is to detect earlier software failures caused by unpredictable hardware faults or system overload. The proposal focuses more precisely on scheduler failures like a deadline miss and a delayed switching context time. Proposed monitor can be used as a standalone scheduler monitor or as a part of redundant system controller. The assumption is that the scheduler monitor detects hardware and RTOS kernel faults earliest. This should enhance RTOS system reliability and safety.

Czech abstract

Tento článek se zabývá problematikou fault tolerant systémů a přináší návrh na hardwarový monitor scheduleru hard real-time OS. Účelem předkládaného přístupu je detekovat softwarové poruchy způsobené hardwarovými chybami a přetížením systému. Návrh se zaměřuje spíše na poruchy správného chování scheduleru jako neplánované zmeškání deadlinu a zpoždění času přepnutí kontextu. Navrhovaný monitor může být použit jako samostatný systémový monitor nebo jako součást redundantního controlleru. Tento návrh má za úkol zvýšit spolehlivost a bezpečnost real-time systému.
