Hello, I'm Alexis Student in image processing. During my training I have to implement an embedded OS but I not quite sure which one to chose. We are devloping a smart camera for image processing based on the Geode GX2 400MHz with 128MB RAM and compactflash memory. Curently we use a real-time OS based on the Linux Monta Vista distribution. Many of our customer are asking for an XP embedded version but I'm affraid XPe will eat up a large amount of RAM. Since image processing could require a lot of RAM maybe WinCE would be better suited. I would like to know if anyone already tried to implement XPe on such hardware for image processing purpose. What is minimum amount of RAM required by XPe in graphic mode with the following IO support: VGA (CS5535 Geode companion), USB, RS232, Ethernet and network support? Any advice/recommendation will be welcomed.
