Qhov txiaj ntsig tseem ceeb ntawm ib qho ISA yog tias cov nyiaj tau los ua tsis tau them se rau cov nyiaj tau los lossis peev nyiaj se. Qhov no ua rau lawv txoj hauv kev txaus nyiam los nqis peev rau ntau lab tus tib neeg thiab tau ntau xyoo. Koj tuaj yeem txuag tau hauv ob qhov ISAs sib cais hauv ib xyoo se - ib qho nyiaj ntsuab ISA thiab ib tug stocks thiab shares ISA.

Ua raws li qhov xav tau, qhov tseem ceeb ntawm kev kawm ISA ntawm tus processor yog dab tsi?

Cov Lus Qhia Teeb Architecture ( ISA ) yog ib feem ntawm lub processor uas pom tau rau tus programmer lossis sau compiler. Cov ISA ua tus ciam teb ntawm software thiab hardware. Peb yuav piav qhia luv luv cov txheej txheem qhia pom nyob rau hauv ntau ntawm microprocessors siv niaj hnub no.

Tsis tas li ntawd, vim li cas cov lus qhia teeb tsa architecture tseem ceeb? Ib kev qhia teeb tsa architecture (ISA) yog tus qauv paub daws teeb ntawm lub computer. Nws kuj tseem ua rau muaj kev hloov pauv ntawm microarchitectures ntawm qhov kev siv ntawm ISA, kom qhov kev ua tau zoo dua qub, kev ua tau zoo dua ntawm ISA tuaj yeem khiav software uas khiav ntawm cov tiam dhau los ntawm kev siv.

Ib qho ntxiv, ISA yog dab tsi thiab vim li cas nws tseem ceeb hauv kev tsim processor?

Cov kev qhia teeb tsa architecture (los yog ISA ) yog ib qho ntawm feem ntau tsim nyog teeb meem uas a CPU designer yuav tsum tau txoj cai los ntawm qhov pib. Nta xws li caches, pipelining, superscalar siv, thiab lwm yam, txhua yam yuav grafted rau ib CPU tsim ntev tom qab tus thawj tsim yog obsolete.

Dab tsi ua rau ISA zoo?

A zoo ISA yuav tsum muab lub hom phiaj huv rau kev sau cov cai. Hauv luv, txij li lub ISA yog lub interface ntawm lub hardware thiab software, nws yuav tsum ua cov kws tsim kho vajtse zoo siab (yooj yim rau kev siv tau zoo) thiab ua tus tsim software zoo siab (yooj yim tsim zoo code rau).
