At least in the usage I've seen realtime refers to guarantees on latency and interrupt timers, not necessarily the amount of latency or polling rate. A system that polls at 1mhz but might miss a poll is not realtime, while a system that polls at 1hz with hard deadline guarantees would be considered realtime.
