Re:The future is ARM and Linux (Score 1)

If linux sometime supports the functionality that is required by realtime applications, maybe, but not now. We have used a powerpc/vxworks based system for nearly a decade, and some people thought that vxWorks has some rather strange features, but at least the realtime part really worked. We switched to a linux based system, and all the realtime stuff blew up. We tried several rt extensions for linux, but they all caused more problems than they solved. Linux kernel is simply not designed for realtime conditions, e.g. just use a some standard posix functions in your code, some global kernel locks get entered and your realtime is dead and gone. After all, vxWorks may be proprietary, but it simply worked well, and I think we spent far more money in tweaking linux and the application code than for vxWorks licenses.
