Multi-core processor Commercial incentives

Mar 14, 2019

Ob peb lag luam motives tsav cov kev loj hlob ntawm cov tub ntxhais multi-core architectures. Xyoo lawm, nws tau ua kom kev ua tau zoo ntawm CPU los ntawm qhov chaw ntawm Circuit Court Integrated Circuit (IC), uas txo tus nqi ntawm ib qho khoom siv ntawm IC. Xwb, rau tib qhov chaw hauv cheeb tsam, ntau dua transistors yuav raug siv rau hauv tus tsim, qhov kev ua haujlwm nce ntxiv, tshwj xeeb tshaj yog rau cov txheej txheem qhia ntawv nyuaj (CISC) architectures. Moos cov nqi tseem nce los ntawm kev txiav txim siab ntawm qhov ntau ntawm cov xyoo dhau los ntawm xyoo pua 20th, los ntawm ntau lub hauv lub xyoo 1980 los mus rau ntau tus gigahertz nyob rau thaum xyoo 2000s.


Raws li tus nqi ntawm kev lag luam ntawm kev ua kom moos ua kom yooj yim dua, kev siv cov lus qhia hauv kev sib piv hauv ntau hom kev ua lag luam tau raug coj los mus txhim kho txoj kev ua tiav tag nrho. Ntau lub cores tau siv rau tib CPU nti, uas yuav ua rau kom zoo muag ntawm CPU chips nrog ob lossis ntau qhov cores. Piv txwv, Intel tau tsim muaj 48-core processor rau kev tshawb nrhiav huab cua; txhua tus tub ntxhais muaj ib qho x 86 architecture.
