I don't think you understand me.  I am not saying pipelining is an 
important thing to use.  It all depends on your requirements.  I am 
simply responding to your statement that "The only pipelining that helps 
performance on a MISC is the instruction prefetch".  I simply don't 
agree with that because what holds back your MISC design depends on your 
MISC design.  BTW, my CPU design doesn't have a prefetch.  It just 
fetches each instruction in parallel with the current instruction 
execution.  Because the instruction fetch unit is in parallel with the 
other units there is no problem with the instruction needing to be 
"prefetched".  It would only be if the design were pipelined that the 
fetch would be a "prefetch".

I don't intend to even try to pipeline my CPU design mainly because I 
don't have the time or interest.  I prefer to try to optimize design 
tradeoffs which don't complicate the design, but should actually 
simplify it.  In other words, optimizing by simplifying... much like 
what Chuck prefers.  But for now I'll keep the SWAP instruction and will 
call an XOR an XOR.

I guess stuff like IF ELSE THEN and OR instead of XOR is what you get 
when you work just to please yourself!  Still, you have to recognize the 
brilliance of the man.
