That was interesting; thanks for posting it. I have three comments:


1) I'd be interested in seeing this extended to include a couple of
RISC processers; say the MIPS and SPARC chips. Is there someone who
knows those machines who can be talked into doing the work?
[See the next message. -John]


2) I've seen the SAS/C compiler generate movem instructions for a
constant block move.


3) Regarding the table at the end, shouldn't


68000 32 16M 16M N Y N Y


be


68000 16/32(4) 16M 16M N Y N Y


(4) 16 bit external bus width; 32 bits internal for some operations
?


thanx again,
<mike
