Using dual pentium, second pentium as a RT target.

Hi,

I don't know how clever you all are, but could it be possible to use the second cpu in a dual core as a real-time target.

If so, you could win the jackpot. (?)

First, you may wish to post this to the real-time board, where you're more likely to get a good answer.

Second, while I don't really know anything about this, I don't think that a dual core processor can be "split", having each CPU controlled individually by 2 different OSes (you will need an RTOS). Plus, I'm not sure RTOSs work on all standard CPUs, but that's just a guess.

I also don't think that it's possible. both cores on the cpu have to be managed by one OS. running a RT target you would have to seclude one core from the other so that no task or process would strike the core. can't believe that this could be done...

Hi,

I can confirm that this is not possible. You cannot have two different OS for each core.

Is this something which may change with this fancy new "virtualization" which Intel and AMD are promising us soon?

Virtual provessor running virtual instruments.  Virtually.

Hi,

What I ment was using two programs side by side.

I tried with Matlab/simulink, when running it took 100% of both cpu's,

Now by giving Matlab only one cpu as prefered cpu, doing so leaves one free cpu to Labview to do its job.

Maybe we could do the same with two Labview programs, one given one entire cpu (the time critical part) the second cpu just do its interface to the user and Windows OS.

So only one cpu will talk to the NI hardware, the other to the rest of the OS.

I will try if I find some time at work.

ps: to synchronize a Simulink simulation with the real-time I found some good .m file based on Windows Multimedia library.
