If the architecture has cache or wait states, it is still subject to be a
moving target. I'm naturally skeptical on all architectures that have
multiple channels, show me an architecture with cache or waits states and
i'll show you a problem ( in regards to real time, that is)

I stand firm that the only proper way to do this is with a 100%
deterministic architecture.
