First up, let me say I don't like writing in assembler. It is not portable,
|
||||
dependant on the particular CPU architecture release and is generally a pig
|
||||
to debug and get right. Having said that, the x86 architecture is probably
|
||||
the most important for speed due to number of boxes and since
|
||||
it appears to be the worst architecture to to get
|
||||
good C compilers for. So due to this, I have lowered myself to do
|
||||
assembler for the inner DES routines in libdes :-).
|
||||
|
||||
The file to implement in assembler is des_enc.c. Replace the following
|
||||
4 functions
|
||||
des_encrypt1(DES_LONG data[2],des_key_schedule ks, int encrypt);
|
||||
des_encrypt2(DES_LONG data[2],des_key_schedule ks, int encrypt);
|
||||
des_encrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
|
||||
des_decrypt3(DES_LONG data[2],des_key_schedule ks1,ks2,ks3);
|
||||
|
||||
They encrypt/decrypt the 64 bits held in 'data' using
|
||||
the 'ks' key schedules. The only difference between the 4 functions is that
|
||||
des_encrypt2() does not perform IP() or FP() on the data (this is an
|
||||
optimization for when doing triple DES and des_encrypt3() and des_decrypt3()
|
||||
perform triple des. The triple DES routines are in here because it does
|
||||
make a big difference to have them located near the des_encrypt2 function
|
||||
at link time..
|
||||
|
||||
Now as we all know, there are lots of different operating systems running on
|
||||
x86 boxes, and unfortunately they normally try to make sure their assembler
|
||||
formating is not the same as the other peoples.
|
||||
The 4 main formats I know of are
|
||||
Microsoft Windows 95/Windows NT
|
||||
Elf Includes Linux and FreeBSD(?).
|
||||
a.out The older Linux.
|
||||
Solaris Same as Elf but different comments :-(.
|
||||
|
||||
Now I was not overly keen to write 4 different copies of the same code,
|
||||
so I wrote a few perl routines to output the correct assembler, given
|
||||
a target assembler type. This code is ugly and is just a hack.
|
||||
The libraries are x86unix.pl and x86ms.pl.
|
||||
des586.pl, des686.pl and des-som[23].pl are the programs to actually
|
||||
generate the assembler.
|
||||
|
||||
So to generate elf assembler
|
||||
perl des-som3.pl elf >dx86-elf.s
|
||||
For Windows 95/NT
|
||||
perl des-som2.pl win32 >win32.asm
|
||||
|
||||
[ update 4 Jan 1996 ]
|
||||
I have added another way to do things.
|
||||
perl des-som3.pl cpp >dx86-cpp.s
|
||||
generates a file that will be included by dx86unix.cpp when it is compiled.
|
||||
To build for elf, a.out, solaris, bsdi etc,
|
||||
cc -E -DELF asm/dx86unix.cpp | as -o asm/dx86-elf.o
|
||||
cc -E -DSOL asm/dx86unix.cpp | as -o asm/dx86-sol.o
|
||||
cc -E -DOUT asm/dx86unix.cpp | as -o asm/dx86-out.o
|
||||
cc -E -DBSDI asm/dx86unix.cpp | as -o asm/dx86bsdi.o
|
||||
This was done to cut down the number of files in the distribution.
|
||||
|
||||
Now the ugly part. I acquired my copy of Intels
|
||||
"Optimization's For Intel's 32-Bit Processors" and found a few interesting
|
||||
things. First, the aim of the exersize is to 'extract' one byte at a time
|
||||
from a word and do an array lookup. This involves getting the byte from
|
||||
the 4 locations in the word and moving it to a new word and doing the lookup.
|
||||
The most obvious way to do this is
|
||||
xor eax, eax # clear word
|
||||
movb al, cl # get low byte
|
||||
xor edi DWORD PTR 0x100+des_SP[eax] # xor in word
|
||||
movb al, ch # get next byte
|
||||
xor edi DWORD PTR 0x300+des_SP[eax] # xor in word
|
||||
shr ecx 16
|
||||
which seems ok. For the pentium, this system appears to be the best.
|
||||
One has to do instruction interleaving to keep both functional units
|
||||
operating, but it is basically very efficient.
|
||||
|
||||
Now the crunch. When a full register is used after a partial write, eg.
|
||||
mov al, cl
|
||||
xor edi, DWORD PTR 0x100+des_SP[eax]
|
||||
386 - 1 cycle stall
|
||||
486 - 1 cycle stall
|
||||
586 - 0 cycle stall
|
||||
686 - at least 7 cycle stall (page 22 of the above mentioned document).
|
||||
|
||||
So the technique that produces the best results on a pentium, according to
|
||||
the documentation, will produce hideous results on a pentium pro.
|
||||
|
||||
To get around this, des686.pl will generate code that is not as fast on
|
||||
a pentium, should be very good on a pentium pro.
|
||||
mov eax, ecx # copy word
|
||||
shr ecx, 8 # line up next byte
|
||||
and eax, 0fch # mask byte
|
||||
xor edi DWORD PTR 0x100+des_SP[eax] # xor in array lookup
|
||||
mov eax, ecx # get word
|
||||
shr ecx 8 # line up next byte
|
||||
and eax, 0fch # mask byte
|
||||
xor edi DWORD PTR 0x300+des_SP[eax] # xor in array lookup
|
||||
|
||||
Due to the execution units in the pentium, this actually works quite well.
|
||||
For a pentium pro it should be very good. This is the type of output
|
||||
Visual C++ generates.
|
||||
|
||||
There is a third option. instead of using
|
||||
mov al, ch
|
||||
which is bad on the pentium pro, one may be able to use
|
||||
movzx eax, ch
|
||||
which may not incur the partial write penalty. On the pentium,
|
||||
this instruction takes 4 cycles so is not worth using but on the
|
||||
pentium pro it appears it may be worth while. I need access to one to
|
||||
experiment :-).
|
||||
|
||||
eric (20 Oct 1996)
|
||||
|
||||
22 Nov 1996 - I have asked people to run the 2 different version on pentium
|
||||
pros and it appears that the intel documentation is wrong. The
|
||||
mov al,bh is still faster on a pentium pro, so just use the des586.pl
|
||||
install des686.pl
|
||||
|
||||
3 Dec 1996 - I added des_encrypt3/des_decrypt3 because I have moved these
|
||||
functions into des_enc.c because it does make a massive performance
|
||||
difference on some boxes to have the functions code located close to
|
||||
the des_encrypt2() function.
|
||||
|
||||
9 Jan 1997 - des-som2.pl is now the correct perl script to use for
|
||||
pentiums. It contains an inner loop from
|
||||
Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk> which does raw ecb DES calls at
|
||||
273,000 per second. He had a previous version at 250,000 and the best
|
||||
I was able to get was 203,000. The content has not changed, this is all
|
||||
due to instruction sequencing (and actual instructions choice) which is able
|
||||
to keep both functional units of the pentium going.
|
||||
We may have lost the ugly register usage restrictions when x86 went 32 bit
|
||||
but for the pentium it has been replaced by evil instruction ordering tricks.
|
||||
|
||||
13 Jan 1997 - des-som3.pl, more optimizations from Svend Olaf.
|
||||
raw DES at 281,000 per second on a pentium 100.
