We are currently porting an existing WCET analy- sis tool, Bound-T, to the Renesas H8/3292 microprocessor. To reach a more widespread use, WCET analysis tools This microprocessor is used in Lego Mindstorms [11], an need to be a standard part in the education of embedded off-the-shelf kit of Lego bricks for building and controlling systems developers. Many real-time courses in academia small prototype robots. This kit is used in many real-time use Lego Mindstorms, an off-the-shelf kit of Lego bricks courses in academia. Thereby static WCET analysis could for building and controlling small prototype robots. We be regularly used in the education of the embedded system describe work on porting the Bound-T WCET analysis developers of tomorrow. tool to the Lego Mindstorms microprocessor; the Renesas However, for achieving system predictability and to H8/3292. We believe that this work will make students, and make best use of calculated WCET estimates, the complete indirectly the industry of tomorrow, aware of the benefits of system needs to be developed with timing predictability in WCET analysis tools.
