I really haven't done any serious real-time since my DEC days. I was a software specialist for DEC in Dallas, who specialized in real-time apps for RT-11 and RSX. At that time I was handling in excess of 3000 interrupts per second in assembler on a downloadable RSX-11S image. This was on old hardware by today's standards, I would think.
For real-time what is expected interrupt rate on an ARM? BBB specifically?
