Performance analysis of a RTOS by emulation of an embedded system

K. Weiss, T. Steckstor, W. Rosenstiel
Proceedings Tenth IEEE International Workshop on Rapid System Prototyping. Shortening the Path from Specification to Prototype (Cat. No.PR00246)  
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.  ...

Exploiting FPGA-features during the emulation of a fast reactive embedded system

Karlheinz Weiß, Thorsten Steckstor, Gernot Koch, Wolfgang Rosenstiel
1999 Proceedings of the 1999 ACM/SIGDA seventh international symposium on Field programmable gate arrays - FPGA '99  
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.  ...
