cpu32 vs cpu32+ instruction set

2004-11-20 by Aaron J. Grier

I'm attempting to come up with a canonical breakdown of the various
members of the 68k family by chip vs instruction set.

are the instruction sets for CPU32 and CPU32+ core identical?  I've
never had my hands on a CPU32+ chip, I've only used 68331 (which is
CPU32).

also, am I correct in assuming that any CPU32 or CPU32+ chips are a
complete superset of the original 68000 ISA (instruction set
architecture: instruction set, addressing modes, register set)?

Aaron,
 
There is exactly ZERO difference between the CPU32 and the CPU32+ instruction set.
 
The difference is with the external bus structure. 
 
Regards,
 
Charlie
