Abstract

Paper describes performance of embedded real-time system controlled by Linux. Interrupt latency is taken into account as a main measured parameter in further considerations. To improve and minimize system's interrupt latency two separate approaches were evaluated. Obtained results proved that its possible to build a hard real-time system based on a modified Linux kernel.
