Ib tug microprocessor yog ib lub computer processor uas sib txuas nrog cov haujlwm ntawm ib chav ua haujlwm ntawm ib qho kev sib tshuam nkaus xwb (IC), [1] lossis feem ntau ntawm cov kev sib txuas ua ke [2] Lub microprocessor yog ib lub hom phiaj, moos uas tau tsav, sau npe raws li, muaj kev cuam tshuam hauv digital uas lees txais binary cov ntaub ntawv raws li cov lus qhia, ua raws li cov lus qhia nyob rau hauv nws lub cim xeeb, thiab muab cov txiaj ntsim ua cov zis. Microprocessors muaj ob qho combinational logic thiab tshwm sim ntawm cov logic. Microprocessors khiav lag luam ntawm cov zauv thiab cov cim uas sawv cev hauv tus zauv cim binary.


Kev koom ua ke ntawm tag nrho CPU mus rau ib tus ntiv tes los sis ob peb daim tawv nqaij kom txo tau tus nqi ntawm kev ua fais fab, nce kev nce nqi. Integrated circuit processors yog tsim los ntawm cov xov tooj ntau los ntawm cov txheej txheem kev sib tw, uas ua rau ib tus nqi tsawg tsawg. Chip ib leeg ntiav ua rau kom muaj kev cia siab vim tias muaj ntau ntau cov hluav taws xob txuas uas yuav ua tsis tau. Raws li microprocessor designs txhim kho, tus nqi ntawm kev tsim ib nti (nrog cov khoom me me ua rau ntawm ib lub semiconductor nti tib hom) feem ntau nyob qis ib yam raws li Pob zeb txoj cai.


Ua ntej microprocessors, cov tshuab computer tau tsim los siv cov racks ntawm circuit boards nrog ntau qhov nruab nrab thiab me me. Microprocessors sib sau ua ke rau hauv ib los yog ob peb ntu loj ICs. Txuas ntxiv rau hauv microprocessor muaj peev xwm txij li nws tau txais lwm cov ntaub ntawv ntawm cov koos pis tawj kiag (dhau los ntawm kev sib tw ntawm kev kho vajtse), nrog ib lossis ntau lub microprocessors uas siv txhua yam ntawm cov kabmob tsawg tshaj plaws nruab thiab cov cuab yeej txuas mus rau lub loj tshaj mainframes thiab supercomputers.
