How low can you go? PID Performance?

I can't wait for Toy Story 3 to come out in cinemas. I still remember when I skip a couple of classes in university to see Toy Story with a couple of good friends and how long we stayed afterwards discussing the merits of the 3D generated characters.


One of my favorites sequences in Toy Story 2 is when in Al's Toy Barn they are looking for Buzz and drive along the isle where the Barbies are playing and one of the games go "how far can you go, how far can you go".


I guess that applies today to computing plaftorm used for control. There is a wide variety, from multicore CPUs machines to 8 bit processors and the control engineer has to find the balance between performance and cost (among other things). I wanted to test the performance on three embedded computing platforms that I have on my desk. A PXI, my Laptop, a CompactRIO and and embedded ARM board.

I've successfully run Simulation Loops (the backbone of simulations in LabVIEW) in all of those platforms. More soon!
