Re: FPGApple + ARM?



You're raining on my parade, man. Talking like a compiler writer!
Hopefully there's another "Not that I don't love it, you understand!"
coming! ;-)

Anyway, from the points you make (all valid of course) the nature of
RISC tends towards a division into processing instructions and memory
access instructions. Combined with a relatively large set of general
purpose registers, this leads to the kind of orthogonality I was
referring too. In the ARM any operand can be "barrel-shifted" for
"free" - all within one cycle for instance.

As you say, not much help there from 6502 experience. I was quite taken
aback when I discovered the ARM had no stack pointer!

Cheers,
Nick.
