Performance analysis of a RTOS by emulation of an embedded system
Proceedings Tenth IEEE International Workshop on Rapid System Prototyping. Shortening the Path from Specification to Prototype (Cat. No.PR00246)
Preserved Fulltext
This paper analyzes the performance of two different real-time operating systems. Therefore, we used a real benchmark embedded system design with fast external reaction times of about 220µs. ...
We show that for such fast reactive systems, the software overhead of a real-time operating system becomes a limiting factor. ...
The analysis of the performance improvements with respect to different cache configurations in fast real-time systems, which run under control of a RTOS, is an interesting research topic. 3. ...

This paper presents the emulation of an embedded system with hard real time constraints and response times of about 220µs. ...
We show that for such fast reactive systems, the software overhead of a Real Time Operating System (RTOS) becomes a limiting factor, consuming up to 77% of the total execution performance. ...
That leads to the fact that the RTOS must not perform so many task switches, which results in a dramatic decrease of execution performance consumption by the RTOS. ...
