Abstract
To reach a more widespread use, WCET analysis tools need to be a standard part
in the education of embedded systems developers. Many real-time courses in
academia use Lego Mindstorms, an off-the-shelf kit of Lego bricks for building
and controlling small prototype robots. We describe work on porting the Bound-T
WCET analysis tool to the Lego
Mindstorms microprocessor; the Renesas
H8/3292. We believe that this work will make students, and indirectly the
industry of tomorrow, aware of the benefits of WCET analysis tools. We also
present the real-time laboratory framework in which this WCET analysis tool
will be used. The framework has been developed with schedulability and timing
predictability in mind, and is already used in a number of real-time courses
given at Mälardalen University in Sweden. The developed WCET tool and the
real-time laboratory framework will be freely available for academic use.
