1 Microcontroller txhais
Raws li lub microcontroller yog cov lej lej lej, lub cim xeeb, lub sijhawm / lub laij lej, thiab ntau yam / O circuits, thiab lwm yam kev koom ua ke rau hauv ib lub nti, ua rau lub hauv paus ua tiav kev suav, nws tseem hu ua ib lub tshuab microcomputer.
Qhov kev zov me nyuam hauv microcontroller nco siv ze nrog microcontroller hardware thiab peripheral hardware circuits, yog qhov txawv ntawm cov software ntawm lub PC, thiab hu ua microcontroller program li firmware.Feem ntau, microprocessor yog CPU ntawm ib qho kev sib koom ua ke, thaum lub microcontroller yog CPU, ROM, RAM, VO, timer, thiab lwm yam. tag nrho ntawm ib qho kev sib xyaw ua ke.Piv nrog CPU, microcontroller tsis muaj lub zog siv hluav taws xob zoo, thiab tsis muaj MemoryManaaement Unit, uas ua rau microcontroller tsuas tuaj yeem ua haujlwm qee qhov kev tswj hwm ib leeg thiab yooj yim, logic, thiab lwm yam dej num, thiab nws tau siv dav hauv kev tswj cov cuab yeej, sensor teeb liab ua. thiab lwm yam kev lag luam, xws li qee yam khoom siv hauv tsev, khoom siv hluav taws xob, cov cuab yeej hluav taws xob, thiab lwm yam.
2 Kev sib xyaw ntawm microcontroller
Lub microcontroller muaj ntau qhov chaw: central processor, nco, thiab input / output:
-Central processor:
Lub hauv paus processor yog lub hauv paus tseem ceeb ntawm MCU, suav nrog ob lub ntsiab ntawm tus neeg teb xov tooj thiab tus tswj hwm.
- Tus neeg ua haujlwm
Tus neeg teb xov tooj muaj cov lej lej & cov lej ntsuas (ALU), accumulator thiab sau npe, thiab lwm yam. Lub luag haujlwm ntawm ALU yog ua cov lej lej lossis cov lej ua haujlwm ntawm cov ntaub ntawv nkag.ALU muaj peev xwm ntxiv, rho tawm, sib piv, lossis sib piv qhov loj ntawm ob cov ntaub ntawv no, thiab thaum kawg khaws cov txiaj ntsig hauv cov khoom sib xyaw.
Tus neeg teb xov tooj muaj ob txoj haujlwm:
(1) Ua ntau yam kev ua lej lej.
(2) Txhawm rau ua ntau yam kev ua haujlwm zoo thiab ua qhov kev sim siab, xws li kev ntsuas tus nqi xoom lossis kev sib piv ntawm ob qhov txiaj ntsig.
Txhua qhov kev ua haujlwm ua los ntawm tus neeg teb xov tooj yog qhia los ntawm kev tswj cov teeb liab los ntawm tus maub los, thiab, thaum lub sijhawm ua lej lej ua rau qhov tshwm sim lej, qhov kev ua haujlwm ntawm lub cav ua qhov kev txiav txim.
-Controller
Tus maub los yog tsim los ntawm cov kev pab cuam txee, kev qhia ntawv sau npe, kev qhia decoder, lub sij hawm lub tshuab hluav taws xob thiab kev tswj xyuas kev ua haujlwm, thiab lwm yam. Nws yog "kev txiav txim siab lub cev" uas teeb meem cov lus txib, piv txwv li kev tswj hwm thiab tswj kev ua haujlwm ntawm tag nrho microcomputer system.Nws lub luag haujlwm tseem ceeb yog:
(1) Txhawm rau muab cov lus qhia los ntawm kev nco thiab qhia qhov chaw ntawm cov lus qhia tom ntej hauv kev nco.
(2) Txhawm rau txiav txim siab thiab ntsuas cov lus qhia thiab tsim kom muaj kev tswj hwm kev ua haujlwm sib raug zoo los pab txhawb kev ua tiav ntawm qhov kev txiav txim.
(3) Qhia thiab tswj cov kev taw qhia ntawm cov ntaub ntawv ntws ntawm CPU, nco, thiab cov khoom siv nkag thiab tso tawm.
Lub microprocessor interconnects lub ALU, txee, sau npe thiab tswj seem los ntawm lub tsheb npav sab hauv, thiab txuas mus rau sab nraud nco thiab input / output interface circuits los ntawm lub tsheb npav sab nraud.Lub tsheb npav sab nraud, tseem hu ua lub tsheb npav, tau muab faib rau hauv cov ntaub ntawv tsheb npav DB, chaw nyob tsheb npav AB thiab tswj lub npav CB, thiab txuas nrog ntau yam khoom siv peripheral los ntawm kev tawm tswv yim / tso tawm interface Circuit Court.
- Nco
Lub cim xeeb tuaj yeem muab faib ua ob pawg: cov ntaub ntawv nco thiab kev ua haujlwm nco.
Cov ntaub ntawv nco yog siv los khaws cov ntaub ntawv thiab cov kev pab cuam khaws cia yog siv los khaws cov kev pab cuam thiab cov kev txwv.
-Input/Output -Txuas los yog tsav tsheb sib txawv
Serial kev sib txuas lus chaw nres nkoj-piv cov ntaub ntawv ntawm MCU thiab cov khoom siv sib txawv, xws li UART, SPI, 12C, thiab lwm yam.
3 Microcontroller kev faib tawm
Hais txog tus naj npawb ntawm cov khoom, microcontrollers tuaj yeem faib ua 4-ntsis, 8-ntsis, 16-ntsis, thiab 32-ntsis.Hauv kev siv cov tswv yim, 32-ntsis nyiaj rau 55%, 8-ntsis nyiaj rau 43%, 4-ntsis nyiaj rau 2%, thiab 16-ntsis nyiaj rau 1%
Nws tuaj yeem pom tau tias 32-ntsis thiab 8-ntsis microcontrollers yog cov siv ntau tshaj plaws microcontrollers hnub no.
Qhov sib txawv ntawm tus lej ntawm cov khoom tsis sawv cev rau qhov zoo lossis qhov tsis zoo microprocessors, tsis yog qhov ntau dua cov khoom siv lub microprocessor zoo dua, thiab tsis yog qhov tsawg dua cov khoom siv microprocessor.
8-ntsis MCUs muaj ntau yam;lawv muab cov programming yooj yim, kev siv hluav taws xob thiab cov pob me me (qee qhov tsuas muaj rau tus pins).Tab sis cov microcontrollers no feem ntau tsis siv rau kev sib txuas lus thiab kev sib txuas lus.
Feem ntau cov kev cai network thiab kev sib txuas lus software stacks yog 16- lossis 32-ntsis.Kev sib txuas lus peripherals muaj rau qee cov khoom siv 8-ntsis, tab sis 16- thiab 32-ntsis MCUs feem ntau yog qhov kev xaiv zoo dua.Txawm li cas los xij, 8-ntsis MCUs feem ntau yog siv rau ntau yam kev tswj, kev paub, thiab kev siv interface.
Architecturally, microcontrollers tuaj yeem muab faib ua ob pawg: RISC (Raws li Kev Qhia Teeb Meem Computers) thiab CISC (Complex Instruction Set Computers).
RISC yog microprocessor uas ua tiav tsawg dua cov lus qhia hauv computer thiab pib hauv xyoo 1980s nrog MIPS mainframe (piv txwv li, RISC cov cav tov), thiab cov microprocessors siv hauv RISC cov cav tov yog sib sau ua ke hu ua RISC processors.Nyob rau hauv txoj kev no, nws muaj peev xwm ua haujlwm ntawm tus nqi nrawm dua (ntau lab ntxiv cov lus qhia ib ob, lossis MIPS).Vim hais tias cov khoos phis tawj xav tau cov transistors ntxiv thiab cov ntsiab lus hauv Circuit Court los ua txhua hom kev qhia, qhov loj dua lub khoos phis tawj cov lus qhia ua rau microprocessor nyuaj thiab ua haujlwm qeeb dua.
CISC suav nrog cov txheej txheem microinstructions uas yooj yim rau kev tsim cov kev pab cuam uas khiav ntawm lub processor.Cov lus qhia yog tsim los ntawm cov lus sib dhos, thiab qee qhov kev ua haujlwm uas tau ua los ntawm software yog siv los ntawm kev qhia kho vajtse hloov.Tus programmer txoj haujlwm yog li ntawd txo qis, thiab qee qhov kev txiav txim qis qis lossis kev ua haujlwm tau ua tiav ib txhij hauv txhua lub sijhawm qhia kom ua tiav qhov nrawm ntawm lub khoos phis tawj, thiab qhov system no hu ua complex instruction system.
4 Cov ntsiab lus
Ib qho kev sib tw loj rau niaj hnub no automotive electronics engineers yog tsim kom muaj tus nqi qis, tsis muaj teeb meem, thiab txawm tias muaj kev tsis ua haujlwm ntawm lub tsheb, hauv kev ua haujlwm ntawm lub tsheb maj mam txhim kho tam sim no, microcontrollers yuav tsum txhim kho kev ua haujlwm. ntawm automotive electronic control units.
