Thaum yuav ib lub ntsiav tshuaj, tej zaum koj yuav tsis xav txog hom processor, lossis CPU, nws muaj. Txawm li cas los xij, CPU rau cov ntsiav tshuaj txiav txim siab tias nws ceev npaum li cas thiab hom apps twg nws tuaj yeem khiav, yog li koj yuav tsum paub yuav ua li cas qhia yog tias lub ntsiav tshuaj processor yog raws li cov haujlwm uas koj xav tau ua.
Cov ntaub ntawv hauv kab lus no siv dav rau cov ntsiav tshuaj ua los ntawm ntau lub tuam txhab (Google, Apple, Samsung, thiab lwm yam).
Tus txheej txheem zoo rau lub ntsiav tshuaj yog dab tsi?
Lub hom phiaj lossis cov qauv tsim ntawm lub processor tsis muaj teeb meem ntau npaum li nws cov kev qhia tshwj xeeb, tshwj xeeb yog nws qhov nrawm thiab tus lej ntawm cov cores nws muaj. Tus processor feem ntau plays qhov tseem ceeb ntawm tus nqi ntawm cov ntsiav tshuaj. Cov ntsiav tshuaj muaj zog tshaj plaws ntawm kev ua lag luam niaj hnub no, xws li Microsoft Surface Pro 7, muaj octa-core CPUs nrog kev ua haujlwm nrawm dua 2 GHz.
Yog tias koj tsuas xav tau lub ntsiav tshuaj los nyeem phau ntawv thiab xauj lub vev xaib, koj tuaj yeem nrhiav cov ntsiav tshuaj nyiaj txiag uas muaj lub zog ua haujlwm txaus rau cov hom phiaj ntawd. Yog tias koj xav siv lub ntsiav tshuaj los ua si 3D games lossis ua cov duab tsim ua haujlwm, CPU siab dua yog qhov tsim nyog.
ARM processors
Feem ntau cov ntsiav tshuaj siv lub processor architecture tsim los ntawm ARM. Lub tuam txhab no tsim cov txheej txheem txheej txheem txheej txheem thiab tom qab ntawd tso cai cov qauv tsim rau lwm lub tuam txhab los tsim khoom. Raws li qhov tshwm sim, muaj qhov zoo sib xws ARM-based processors tsim los ntawm ntau lub tuam txhab. Piv txwv li, thaum iPhones siv lub tswv yim CPU tsim los ntawm Apple, nws yog raws li ARM architecture.
Qhov feem ntau ARM processor tsim rau cov ntsiav tshuaj yog raws li Cortex-A. Cov qauv tsim no suav hais tias yog systems-on-a-chip (SoCs) vim tias tus qauv tsim ua ke nrog RAM thiab cov duab kos rau hauv ib qho silicon nti. Qhov no muaj qee qhov cuam tshuam, vim tias ob qho tib si chips 'processor cores yuav muaj qhov sib txawv ntawm lub cim xeeb thiab cov duab sib txawv, uas tuaj yeem ua rau muaj kev sib txawv hauv kev ua haujlwm.
Cov neeg tsim khoom tuaj yeem hloov kho tus qauv, tab sis feem ntau, kev ua tau zoo yog qhov zoo sib xws ntawm cov khoom hauv tib lub hauv paus tsim. Qhov tseeb ceev tuaj yeem sib txawv vim tias muaj pes tsawg lub cim xeeb, lub platform lub operating system, thiab cov duab processor. Txawm li cas los xij, yog tias ib tus processor ua raws li Cortex-A8 thaum lwm tus yog raws li Cortex-A9, tus qauv siab dua feem ntau muaj kev ua tau zoo dua ntawm qhov sib xws.
Hauv qab no yog cov npe ntawm Cortex-A qauv thiab nta:
| processor | |||
|---|---|---|---|
| Cortex-A5 | Kev siv hluav taws xob qis tshaj | Nyob ib leeg-core | moos nrawm ntawm 300 thiab 800 MHz |
| Cortex-A8 | Tus processor me me nrog kev tshaj tawm zoo dua li A5 | Ntaus ib leeg lossis dual-core | moos ceev ntawm 600 MHz thiab 1.5 GHz |
| Cortex-A9 | Ntau tshaj ntawm cov processors | Feem ntau dual-core tab sis muaj txog li plaub | moos ceev ntawm 800 MHz thiab 2 GHz |
| Cortex-A12 | Zoo ib yam li A9 tab sis nrog txoj kev tsheb npav dav dua thiab txhim kho caching | Muaj txog li plaub cores | moos nrawm mus txog 2 GHz |
| Cortex-A15 | 32-ntsis tsim | Feem ntau dual lossis plaub-ntxhais | moos ceev ntawm 1 GHz thiab 2 GHz |
| Cortex-A17 | Nov dua, ua tau zoo dua 32-ntsis tsim zoo ib yam li A15 tab sis nrog kev ua tau zoo me ntsis | Txog plaub lub processor cores | moos ceev ntawm 1.5 GHz thiab tshaj 2 GHz |
| Cortex-A53 | thawj tus tshiab 64-ntsis processors | Muaj nruab nrab ntawm ib thiab plaub cores | moos ceev ntawm 1.5 GHz thiab tshaj 2.3 GHz |
| Cortex-A57 | Lub zog 64-ntsis processor npaj rau cov neeg siv khoom siv hluav taws xob thiab khoos phis tawj ntau dua li cov ntsiav tshuaj | Muaj nruab nrab ntawm ib thiab plaub cores | moos nrawm mus txog 2 GHz |
| Cortex-A72 | Xeem 64-ntsis processor, npaj rau cov neeg siv khoom siv hluav taws xob lossis PCs ntau dua li cov ntsiav tshuaj | Muaj nruab nrab ntawm ib thiab plaub cores | moos nrawm txog 2.5 GHz |
