! Huh !

<hrrrm> The conventional issue about RISC is the reduced number of
instructions for simple decoding by the cpu's instruction decoder.

Just because the cpu can decode instructions in one clock cycle
does not necessarily make the CPU a 'RISC' design when it inherently
has to cope with CISC type instructions - which have a huge "set" !
