Cov xibfwb nyob rau hauv lub nruab

Mar 08, 2019

Embedded processors yuav tawg ua ob pawg. Ordinary microprocessors (μP) siv sib xyaw ua ke rau cov cim xeeb thiab cov peripherals. Microcontrollers (μC) muaj nyob rau ntawm chip peripherals, yog li txo kev siv zog, qhov loj me thiab nqi. Hauv kev sib piv rau lub lag luam ntawm tus kheej lub computer, ntau ntau yam yooj yim CPU architectures siv vim software yog kev cai-tsim rau ib daim ntawv thov thiab tsis yog khoom muag khoom los ntawm cov neeg siv kawg. Ob leeg Von Neumann thiab ntau theem ntawm Harvard architectures siv. RISC thiab cov kev lag luam uas tsis yog-RISC raug pom. Lo lus ntev sib txawv ntawm 4-ntsis mus rau 64-yas thiab tshaj, tab sis feem ntau raug nyob twj ywm 8/16-ntsis. Feem ntau cov architectures tuaj nyob rau hauv ib tug ntau ntawm txawv variants thiab duab, ntau ntawm uas kuj tsim los ntawm ob peb sib txawv tuam txhab.


Ntau lub microcontrollers tau tsim rau kev siv lub tshuab. General-purpose microprocessors tseem siv tau rau hauv lub nruab system, tab sis, feem ntau, yuav tsum muaj kev txhawb zog ntau tshaj li cov kev sib txuas lus microcontrollers.
