Microprocessor History 64-ntsis designs nyob rau hauv tus kheej computers

Mar 09, 2019

Thaum 64-ntsis microprocessor designs tau siv nyob rau hauv ntau qhov kev lag luam txij thaum ntxov 1990s (nrog rau Nintendo 64 gaming console nyob rau hauv 1996), thaum ntxov 2000s pom qhov qhia txog 64-ntsis microprocessors targeted tom PC market.


Nrog AMD qhia txog 64-ntsis architecture rov qab-tshaj x 86, x 86-64 (tseem hu ua AMD64), nyob rau lub Cuaj Hli Ntuj 2003, tom qab Intel ze ntawm siab tshaj 64-ntsis extensions (thawj hu ua IA-32e los yog EM64T, tom qab renamed Intel 64), lub sij hawm 64-ntsis pib. Ob versions tau khiav 32-qhov kev siv legacy applications tsis muaj kev ua txhaum kev cai li no tus tshiab 64-ntsis software. Nrog rau kev khiav hauj lwm nruab Windows XP x 64, Windows Vista x 64, Qhov rai 7 x 64, Linux, BSD, thiab macOS khiav 64-ntsis natively, software yog tseem mus rau siab siv cov peev txheej ntawm cov processors. Qhov kev txav mus rau 64 cov khoom yog ntau tshaj qhov nce hauv qhov me me ntawm IA-32 raws li nws tseem muaj cov xov tooj ntawm cov hom phiaj sau npe.


Qhov kev txav mus rau 64 cov khoom los ntawm PowerPC tau npaj txij thaum lub architecture tsim nyob rau hauv lub ntxov 90s thiab tsis yog ib qho tseem ceeb ntawm incompatibility. Cov npe ntawm cov zauv muaj ntau dua li cov ntaub ntawv hais txog cov ntaub ntawv, tab sis, raws li qhov teeb meem nrog IA-32, ob qhov floating point thiab vector units tau khiav hauj lwm ntawm lossis siab dua 64 tshooj rau ntau xyoo. Tsis zoo li muaj dabtsi tshwmsim thaum IA-32 tau ncua mus rau x 86-64, tsis muaj npe tshiab sau npe tau ntxiv rau hauv 64-ntsis PowerPC, yog li kev ua tau zoo thaum siv 64-ntsis hom rau kev siv ua tsis siv qhov chaw nyob loj dua .

Nyob rau hauv 2011, ARM nkag tau ib tug tshiab 64-ntsis ARM architecture.
