Another thing to keep in mind that procs with the ARM9E core are
fairly capable DSPs in their own right. Just the addition of a decent
MAC operation gives a huge boost over standard MPUs/MCUs. When you can
get an ARM9E processor for US$16 in piece quantities, that opens the
door to doing a lot of interesting things. I see it as a
first-generation integer-only MMX-class Pentium rather than the
multi-core behemoths we have today. Couple the proc with a very
tightly embedded O/S like FreeRTOS, and code away.
