Tus microprocessor yog lub plawv ntawm lub khoos phis tawm. Lub microprocessor tseem ua tiav muaj kev vam meej hauv cov cuab yeej hluav taws xob hauv tsev. Nws ntsiag to kov yeej tag nrho lub ntiaj teb. Thiab niaj hnub no ib pab tub rog loj heev ntawm cov neeg pabcuam hluav taws xob tau tuaj pab rau tib neeg.
Kev Txhais Tau
Lub tshuab microprocessor yog lub nruab nrab ntawm lub koos pij tawj ntawm tus kheej, tsim los ua cov laj thawj thiab kev ua haujlwm ntawm cov ntaub ntawv, kom ua tiav thiab xa cov ntaub ntawv thiab tswj cov haujlwm ntawm txhua chav ntawm lub tshuab.
Lub microprocessor yog tsim nyob rau hauv ib lossis ntau cov kev sib txuas ntawm cov xov hluav taws xob sib xyaw ua ke ntawm cov kab sib xyaw. Muaj kev tswj cov hluav taws xob sib txuas, cov hloov pauv ntxiv, cov ntawv sau npe, cov phiaj xwm kev pab cuam thiab lub cim me me ceev.
Microprocessor siv cov haujlwm tseem ceeb hauv qab no:
- decryption thiab nyeem ntawv ntawm cov ntaub ntawv los ntawm lub cim xeeb loj
- txais cov lus txib thiab nyeem cov ntaub ntawv los ntawm kev sau npe ntawm cov hloov kho ntawm cov khoom siv sab nraud
- cov ntaub ntawv ua, sau lawv mus rau lub cim xeeb tseem ceeb, nrog rau kev sau ntawv mus rau cov ntawv sau npe ntawm cov hloov kho ntawm cov khoom siv sab nraud
- tsim ntawm tswj cov cim ntawm lwm cov block thiab computer nodes
Los ntawm keeb kwm
Tau ntev, cov khoom siv hauv nruab nrab tau tsim los ntawm ib leeg microcircuits ntawm me me mus rau nruab nrab kev koom ua ke, uas muaj los ntawm ib mus txog ntau pua transistors. Txawm hais tias nws qhov kev txo hwj chim pib, kev nthuav dav txuas ntxiv ntawm microprocessor cov nyom tau ua rau lwm cov khoos phis tawm tawm tas mus li.
Thawj 4-lub microprocessor thawj zaug tshwm sim nyob rau xyoo 1970, thiab nws tau siv hauv tshuab hluav taws xob suav. Lub laij lej siv cov binary-decimal arithmetic. Tsis ntev, microprocessors pib tsim ua hauv lwm cov khoom siv, xws li tshuab luam ntawv, cov chaw nres tsheb, thiab ntau lub tshuab thev naus laus zis.
Hauv nruab nrab xyoo 1970, twb tau 8 lub microprocessors nrog 16-ntsis chaw nyob tso cai thawj cov neeg siv khoom lag luam tsim los tsim.
Tam sim no, ib lossis ntau dua microprocessors tau siv los ua cov khoom siv hauv kev suav txhua yam - los ntawm cov khoom siv txawb thiab cov tshuab teeb me me mus rau cov loj supercomputers thiab mainframes.
Yog tias koj saib ib puag ncig, microprocessors yog cov lus qhov txhia chaw: hauv cov khoom siv hluav taws xob, hauv xov tooj ntawm tes, hauv kev sib tw game, hauv hnab tshos khoom ua si, hauv microwave niaj hnub ncu, tshuab ntxhua khaub ncaws, turntables, laser disks, lub laij lej. Txawm lub tsheb tshiab niaj hnub ntim nrog microprocessors, kom tsis txhob hais tawm cov khoom siv roj, cov dav hlau, tsheb ciav hlau, thiab lwm yam.
"Microprocessor" thiab "processor"
Qee tus sau phau ntawv cais cov cuab yeej lawv tus kheej ua microprocessors, uas tau siv nruj me ntsis ntawm ib qho microcircuit. Qhov ntsiab lus no yog qhov tsis zoo nrog kev kawm thiab kev coj ua lag luam. Piv txwv, microprocessors xws li AMD thiab Intel thiab hauv Pentium II thiab SECC pob tau siv rau ntau lub microcircuits.
Vim tias qhov kev faib khoom me me uas tsis yog microprocessors, hauv kev coj ua niaj hnub cov lus "microprocessor" thiab "processor" yuav luag zoo sib xws.
