Jo este sem dneska videl asm k nejakymu DSP od Texase. Brutalita, vektorovy zpracovani dat, paralelne spoustene instrukce, ... a k tomu to jeste bezi na gigahertzu.

LITTLELI: jen houst

jinak na vysvetleni ankety pouzijeme AMD Optimization Guide:


All instructions (x86, x87, 3DNow!", and MMX" instructions) are classified into two types of decodes DirectPath and VectorPath (see DirectPath Decoder and VectorPath Decoder under Early Decoding on page 207 for more information). DirectPath instructions are common instructions that are decoded directly in hardware. VectorPath instructions are more complex instructions that require the use of a sequence of multiple operations issued from an on-chip ROM.

Up to three DirectPath instructions can be selected for decode per cycle. Only one VectorPath instruction can be selected for decode per cycle. DirectPath instructions and VectorPath instructions cannot be simultaneously decoded.


z cehoz plyne, vyhejbat se VectorPath instrukcim.

a jeste poznamka v manualech Intelu jsou zazite jine terminy, ktere ale maji naprosto stejny vyznam - simple instruction, complex instruction.

preji pekny den

tak to verim .-)

btw, trochu zacinam PowerPC asm, legrace.

anketa dopada docela prekvapive

LITTLELI: bych i prijel, nakej matros by tez byl, otazka kde ses.......

GHIVERAN: to beru, prijed .-) ale az skonci ta bourka co tu je :-/

LITTLELI: get stoned, don't worry, be happy :)

to je tak, vylil sem si kybliczek a ted jsem na vsecko nasranej a nejradsi bych vsecko splachnul do hajzlu, uplne vsecko,proste zatahnout za spagatek a vsecky swine zkurveny a vsichni swinaci posrany by byli v pici.

littleli> nejako nechapu, jak to myslis...

ja bych k tomu neco rekl, ale mam tak blbou naladu, ze to radeji neudelam.

uf, uplne me ta anketa vylekala :/

nova anketa

http://hysteria.sk/thement/lispi-0.tar.gz
... interpretr lispu, takova pre verze, ten alokator jsem nakonec vyresil za pouziti phk mallocu (z fbsd)

_freza_: potrebuju nejakej alocator stringu do asm programku a sekvencni alokaci jako strcpy(p, string); p+=strlen(string); si holt dovolit nemuzu takze hledam neco pouzitelnyho

thement: projdi si zdrojaky ecosu... ale jako 'jak malloc/free'? chces to na hrubym zeleze? pokud ti staci uplne primitivni alokator, tak by se asi dal pouzit extent(9) z BSD (teda, neni to pametovej alokator, ale al. ciselnejch rozsahu - coz je stejny)

mozna je neco na http://linuxassembly.org
implementace se daji udelat ruzne, zalezi na pozadavcich na tu implementaci.

inu a tip na nejakou asm implementaci malloc like fce?
