Ib tug microprocessor yog ib tug-chip CPU. Embeddedmicrocontrollers yog ua tiav cov micros ntawm ib nti, suav nrog CPU, nco, thiab input / output circuits. Tab sis nyob rau hauv txhua rooj plaub, a microcomputer yog ib qho kev sib dhos ntawm cov logic circuits, xws li rooj vag thiab flip-flops, uas yog siv los ua cov ntaub ntawv.

Yog li ntawd, qhov piv txwv ntawm microcomputer yog dab tsi?

Lub ntsiab lus ntawm tus kheej lub computer me me nrog amicroprocessor ua lub hauv paus processor yog ib qho piv txwv ntawm amicrocomputer . Lub khoos phis tawj me me me me zoo ib yam li SmartPhone uas muaj lub hauv paus microprocessor yog ib qho piv txwv ntawm microcomputer.

Ib tug kuj yuav nug, dab tsi yog qhov ceev ntawm micro computer? Kev ua ceev ntawm qhov me me khoos phis tawj yog 3-4 mips. Cov ceev ntawm loj khoos phis tawj tuaj yeem ua tau 70-100 mips ntau dua, thiab supercomputers tuaj yeem ua tiav ntau dua 200 mips. Hauv lwm lo lus, lub mainframe lub computer tuaj yeem ua tiav koj cov ntaub ntawv zoo heev sai dua li ib microcomputer . 6.

Tom qab ntawd, dab tsi ua rau microcomputer?

A microcomputer yog lub khoos phis tawj me me, tus nqi pheej yig nrog lub microprocessor raws li nws qhov chaw ua haujlwm nruab nrab (CPU). Nws suav nrog microprocessor, nco, thiab cov khoom siv hluav taws xob tsawg tsawg (I / O) txuas rau ntawm ib lub rooj tsav xwm luam tawm (PCB).

Dab tsi yog ib qho chip microcomputer?

Muab CPU, ROM, RAM, thiab cov ntaub ntawv tawm tswv yim / tso tawm circuitryinto a ib IC yuav ua ib ib leeg - nti microprocessor. Ib leeg - nti microprocessors tseem hu ua " microcomputer units (MCUs), "vim lawv yog ua los ntawm a ib IC.
