There are 2 reelated problems. With a modern-ish
microprocessor
(external=

pipelines, prefetch

etc), you can't know what the CPU is actually doing at any point.
If you=

have an internal cache, it is of course even
worse.
Well. If you need more compute power then a 8085 you have to apply
advanced technics such as caches and superscalar CPUs. Even if you
can
