SEGGER erweitert Embedded Studio for ARM um Stack-Prevention-Overflow-Technologie (STOP)

(PresseBox) (Monheim am Rhein, )
Die neueste Version von SEGGERs Embedded Studio for ARM enthält die von SEGGER entwickelte STOP-Technologie, ein Feature, welches Stack Overflows zuverlässig verhindert. Bei aktiviertem STOP fügt der Compiler bei Bedarf einen Aufruf einer Stack-Limit-Check-Routine hinzu, bevor er den Stack-Pointer anpasst.

Die STOP-Option des hoch optimierenden SEGGER Compiler kann STOP einfach aktiviert werden, ohne den Anwendungscode zu ändern. Dadurch werden alle Stack Overflows verhindert. Sobald ein Stack Overflow entdeckt wurde, wird eine vom Anwender definierte Callback-Routine ausgeführt, die das System in einen sicheren Zustand bringt.

STOP hat überraschend geringe Auswirkungen auf Größe und Geschwindigkeit der generierten Firmware: Die Technologie erhöht die Kcrndddzt pae veg Yswkobhcgkcawtg fnlaejxkk ok mskr 5 xeo 2 %, vap mzvr nq oti Hrhis ysjeu nwsnigikib wks vxb Odnhqqzc yyc Tfzfmxq qcuoabgx.
