Pentium optimizations for DES (BIG)



Here is some output of the static code analysis from
Intel VTUNE of the win32.??? des crypt routine
from LIBDES 4.0

You'll have to fiddle with your text margins to get it looking
right.

Shown are the U and V pipes, clocks, and penalties for:
* unpairable instructs (PU_Inst),
* instructs dependent on previous results (Exp_Flow_Dep_???)
* addresses dependent on previous instructs (Exp_AGI_???)

and the %total time at the instruction, etc.
based on a run of "speed.c" sampled at .25 millisec intervals

A lot of the penalties are the "AGI" flavor, or "address generation interlock"
as in:

mov      bl, dl                                    1
mov      cl, dh
xor      esi, DWORD PTR [ebx+041a5a8h]             3      Exp_AGI_U_Pen:1
<< penalty

which **maybe** can be avoided by moving (in this example)
the "mov bl,dl" to the earliest possible location where the
algorithm semantics are unchanged.  But you have to be careful not to 
kill some other pairing if you do.

If I had more time I'd do it!  ;)  But I wonder if this isn't getting
close to the point of diminishing returns ..... the overall stats for
the encrypt routine showed about 85% pairing, and averaged out to just
slightly less than 1 clock/instruction.
   

Just fyi, the total thruput on my system, a cyrix586 133, was just over 
1M encrypts/sec, CBC.
