Is writing to an MMX/XMM register from a normal 32 bit or 8/16 bit register X (8) times with a single 128-bit one memory write much faster than writing that 8 bit register to memory 16 times?
I haven't seen anyone do this so maybe it's just a bad idea.... (Except in SSE data copy etc....)
In the other hand if it is faster then I don't mind taking credit for any resulting laboratory algorithm upgrades :lol....
Maybe there is already a laboratory timings post for this?
See here (http://www.masm32.com/board/index.php?topic=13248.msg102889#msg102889). The rep movsd/rep stosd variants can compete with SSE2 for large volumes but the difference is still more than marginal.
write 32 bit register ~2 times quickly when do the same with 16 bit register's (http://smiles.kolobok.us/light_skin/girl_witch.gif)

Hi there ...any chance that you can save the .asm's as HTML as so I can translate it to english
This is what I see here:
; ===============================================================

.386

; === Íà÷àëî ïðîãðàììû: ===
CSEG segment use16

Like this:
unless you have some time and want to use Google translate at your end .... and translate them to english

Made you own comment. I made this for myself. May ask me how translate something. Main they say what do this INT or those
Under DOS 186 picture is visible how it drawing from up to down. 386 appear practically immediately on my PC. The difference only one- in MOVSB MOVSD

I meant can you save the .asm's as html , your computer is in Italian? right?
I can not see Italian here
.html stays in the language that it is in then I can translate

Thank you...I will post the English
May be Unicode help?
as I see code use Russian OEM for output

Do you know TASM?
can you translate these shorts CRC32 to MASM ???
Знаете ли вы, TASM?
Вы можете перевести эти шорты CRC32 для MASM??

Here is the English Translation Thanks to Google Translate!
The only thing I did not get is this:
No_File db 'ЋиЁЎЄ ®вЄалвЁп д ©« ', 0Dh,0Ah, 24h ; Failed to open file
Read_Error db 'ЋиЁЎЄ з⥨п д ©« ', 0Dh,0Ah, 24h ; Error reading file
Memory_Error db 'ЋиЁЎЄ Ї ¬пвЁ', 0Dh, 0Ah, 24h ; Error allocating memory
No Language matched it? could be some weird acronym ...
I don't teach TASM, but the asm I learn compile with TASM compiler. I learn Basic at school for wild Hewled Pacard. When I begin asm includes, and when leave Basic
http://www.emu8086.com/ this great for 16 bit asm. some times it need a little correction for TASM
In attach as I see think more modern asm for last TASM compilers . I don't think it very difficult to convert it to masm
