Stack processors never seem to catch on too much,
even though they are
fast. I have a 4MHz Novix chip that can do sorts faster in Forth than a
33 MHz 386 can do in machine code. Sorting 1K 16 bit integers in 19 ms.
Like many DSPs, it can combine several instructions in a single clock
cycle and operate 2 data busses at the same time.
Forth chips are awesome, as is Forth. I've never messed with the
Novix chips (NC4000 series?) but I have a couple of Harris RTX2010 chips
here, as well as one of Chuck Moore's new GA144s. 144 hly simple cores
on a chip! Great stuff. I'll have that on a board soon.
