Aftermarket ECU & RT OS

Hi Paul :

No, but I have looked at other UNIX variants with "real time
extensions".  For what I do (which has nothing to do with EFI or engine
management), they are just way too slow, and take too much processor. 
It's possible that Linux would make sense, for a "one of a kind"
homebrew, but you'd want to see some hard figures on worst-case
interrupt latency, task switch, etc.  

Part of the issue is that "real-time" means different things to
different people.  Most of the UNIX enhancements I've seen concentrate
on things like adding task priorities (which is certainly important),
but do little to address things like worst-case task switch.  Whether
you can live with that depends a lot on what your requirements are.

Frankly, IMO a complex operating system always adds complexity to the
project.  If you don't need that complexity (and I don't see it as being
required for engine management/EFI), why bother ?  To put it another
way, there's a lot to be said for the KISS (Keep It Simple, Stupid)
principle <g>

Cheers
Randall
