Cov khoom siv (khoom ua hauv nruab nrab lossis ntsuas CPU) yog qhov khoom tseem ceeb ntawm lub khoos phis tawm ntawm lub khoos phis tawm. Nws tuaj yeem raug hu lub hlwb ntawm lub computer vim nws ua tiav txhua cov lus qhia ntawm lub tshuab.
Cov Lus Qhia
Kauj ruam 1
Sab nraud, lub processor yog microcircuit lossis cov khoom siv hluav taws xob. Microprocessor yog ib qho tsim muaj uas yog microcircuit me me. Ntau tus neeg siv khoom siv ua kom sib luag thiab microprocessor nrog txhua lwm, tab sis qhov no tsis yog qhov tseeb.
Kauj ruam 2
Tus microprocessor yog ntsia rau hauv chav me ntawm leej niam ntawm tus kheej lub khoos phis tawm. Kev ua tau zoo nyob ntawm nws lub zog. Lub kaw lus cua txias tau tsim rau lub processor, uas tso cai rau nws kom zam dhau qhov ntsuas kub dhau.
Kauj ruam 3
Cov hlwb tshwj xeeb (cov ntaub ntawv sau npe), uas yog nyob hauv processor, tau siv los ua cov ntaub ntawv thiab cov lus qhia uas siv cov ntaub ntawv no. Lub ntsiab ntawm cov processor ua haujlwm yog raws li hauv qab no. Cov ntaub ntawv uas yuav tsum tau muaj thiab qee qhov teeb tsa ntawm cov lus txib tau thauj los ntawm lub cim xeeb hauv qhov xav tau tom qab, tom qab uas lawv tua. Qhov sib lawv liag ntawm cov lus txib yog ib txoj haujlwm.
Kauj ruam 4
Cov yam ntxwv tseem ceeb ntawm processors suav nrog kev nrawm thiab muaj peev xwm me ntsis. Kev nrawm yog txiav txim siab los ntawm qhov ntau zaus ntawm lub processor, ntsuas hauv megahertz thiab qhia pom tias muaj pes tsawg lub voj voog ib thib ob uas cov processor muaj peev xwm ua tau. 1 MHz sib npaug 1,000,000 moos mus ncig.
Kauj ruam 5
Sab hauv lub tshuab tsim muaj ntau lab ntawm transistors thiab lwm yam khoom siv hluav taws xob. Lub ntsiab tseem ceeb hauv lub khoos phis tawm ntawm tus kheej yog lub hauv paus tsim, uas tswj hwm qhov program code. Tab sis txhua qhov khoom siv kho vajtse nws muaj nws lub ua haujlwm pabcuam. Piv txwv li, kab ke tshuab npav khoos phis lossis ntawv tsim video card.
Kauj Ruam 6
Los ntawm tus naj npawb ntawm cores, cov txheej txheem raug muab faib ua ib leeg-ntxhais thiab ntau tus tub ntxhais. Multi-core processors yog cov uas muaj ob lossis ntau qhov cores hauv ib pob lossis ntawm ib qho yuam kev tuag. Ntau lub cores tuaj yeem ua kom ceev cov kev coj ua ntawm cov ntawv thov uas txhawb nqa multithreading.
