IMO real-time has a perfectly good definition. It means a system which doesn't miss any of it's deadlines. So an ABS system *has* to update the current in the solenoids every xms +/-yus - if it meets that, it's real-time target is met.
A human oriented system may have to respond within 10ms to a keypress so as not to appear sluggish.
Real-time has no numerical value, it's about meeting timing specifications.
Then there's hard-real-time and soft-real-time - which is about how badly things go wrong *if* you miss the deadline...
Jaguar has had drive by wire systems for a while now where there actually isn't any physical linkage between the wheel and the tires.
Between the *wheel* and the *tires* - surely there's something there:) If you mean no connection between the "hand wheel" and the "road wheels+tires", then I seriously doubt it. Citation?
Both Xilinx and Altera (who have the high-performance end of the market sewn up between them) allow you to encrypt your configuration bitstream, so design security is not a huge problem any more
imagine the world once we really get serious about robotics. Robot cars, domestic droids, etc. Software engineering could very well become a safety issue.
Hmmm, like there isn't already safety critical code in fly-by-wire planes? ABS controllers? Electric power steering controllers... etc. etc. etc.
It will integrate with Visual Sourcesafe very nicely via a plugin set of menus. No doubt CVS would be possible also, since it's just a set of command-line executions?
Just don't put $Revision: $ in there as it falls apart. You have to use $Revision:: [enough spaces] $. Then it works fine...

FWIW Matlab uses the Maple engine for its symbolic stuff.

Don't Altera get badass points for free dev tools as well then?
