real time system development concept walkthru / tutorial?

Anyone know of any site that gives a good concept walkthru or tutorial on how to build a real time system?

I want to look into it more, but have no experience with real time softwares. Preferably, with c/c++ or java.

anyone?

thanks,
tak

Java and real time don't exactly sound like they go together well.

What part of the real time system are you interested in? There are already a bunch of real time OSes and there's even a real time Linux kernel which I believe is free and open source.

Hi Nothinman,

First off, what is Real Time to you?? I thought real time is like, real time financial stock info streams, with minimal delay, just like the stocks.

what do you mean by real time OSes? I am a very beginner about this topic, so I dont know how to answer "what part of real time system dev are you interested in?" I want to first get a good grasp on the concept, techniques, and terminology first, then i will go further and explore which part I am interested in. As of now, I dont even know how many parts are there....

Can you fill me in?

thanks.

I was thinking Real Time OS with real time scheduling, meaning a RT process is guaranteed exactly x millseconds of running time every x clock ticks. The type of OS used in embedded devices and things like computers used to control machinery.
