1 Fa'amatalaga Microcontroller

Talu ai o le microcontroller o le numera numera, manatua, timer / calculator, ma eseese / O circuits, ma isi mea faʻapipiʻi i totonu o se pu, e fausia ai se faiga faʻapipiʻi atoatoa, e lauiloa foi o se microcomputer chips tasi.

O le polokalame i totonu o le microcontroller memory e faʻaogaina vavalalata ma masini microcontroller ma masini faʻapitoa, e iloga mai le polokalama a le PC, ma e taʻua o le microcontroller program e pei o firmware.E masani lava, o le microprocessor o se PPU i luga o se taʻaloga tuʻufaʻatasia e tasi, aʻo le microcontroller o se PPU, ROM, RAM, VO, timer, ma isi mea uma i luga o se taʻaloga tuʻufaʻatasia e tasi.Pe a faatusatusa i le PPU, microcontroller e leai se malosi faakomepiuta malosi, e leai foi MemoryManaaement Unit, lea e mafai ai e le microcontroller ona naʻo le pulea e tasi ma faigofie, manatu, ma isi galuega, ma lona faʻaaogaina lautele i masini pulea, masini faʻailoga faʻailoga. ma isi fanua, e pei o nisi mea faigaluega fale, mea tau alamanuia, meafaigaluega eletise, ma isi.

2 Le tuufaatasiga o le microcontroller

O le microcontroller e aofia ai le tele o vaega: faʻaogaina totonugalemu, manatua, ma faʻaoga / faʻaogaina:

-Central processor:

O le faʻatonuga tutotonu o le vaega autu o le MCU, e aofia ai vaega autu e lua o le faʻafoe ma le pule.

-Ta'ita'i

O le tagata fa'afoe e aofia ai le numera & logical unit (ALU), accumulator ma resitala, ma isi.O le ALU e mafai ona faʻaopoopo, toesea, faʻafetaui, pe faʻatusatusa le tele o nei faʻamatalaga e lua, ma mulimuli ane teuina le iʻuga i le accumulator.

E lua galuega a le tagata fa'afoe:

(1) Fa'atino galuega fa'atusa eseese.

(2) Fa'atino galuega fa'atatau ma fa'atino su'ega sa'o, e pei o le su'ega o le leai o se tau po'o se fa'atusatusaga o tau e lua.

O fa'agaioiga uma e fa'atino e le tagata fa'afoe e fa'atonuina e fa'ailo fa'atonutonu mai le fa'atonu, ma, a'o maua e se fa'asologa fa'atusa se fa'ai'uga fa'atusa, o se fa'agaioiga talafeagai e maua ai se fa'ai'uga.

- Pule

O le pule e aofia ai le fata polokalame, tusi resitala faatonuga, decoder faatonuga, taimi generator ma le faagaoioiga pule, ma isi O le "tino faia faaiuga" e tuuina atu poloaiga, ie faamaopoopoina ma faatonu le faagaoioiga o le microcomputer system atoa.O ana galuega autu o:

(1) Ia toe aumai se faatonuga mai le manatua ma faailoa le nofoaga o le isi faatonuga i le manatua.

(2) Ia fa'avasega ma fa'ata'ita'i le fa'atonuga ma fa'atupu le fa'ailo fa'atonutonu fa'agaioiga e fa'afaigofie ai le fa'atinoina o le gaioiga fa'apitoa.

(3) Faʻatonu ma faʻatonutonu le faʻatonuga o faʻamaumauga i le va o le PPU, manatua, ma mea e tuʻuina atu ma mea e gaosia.

Ole microprocessor e fa'afeso'ota'i le ALU, fa'atau, resitala ma le vaega fa'atonutonu e ala i le pasi totonu, ma fa'afeso'ota'i i le mafaufau i fafo ma fa'aoga feso'ota'iga fa'aoga/tuuina atu e ala i le pasi fafo.O le pasi i fafo, e taʻua foi o le pasi faʻaoga, ua vaevaeina i le pasi faʻamaumauga DB, tuatusi pasi AB ma le pasi faʻatonutonu CB, ma e fesoʻotaʻi atu i masini faʻaoga eseese e ala i le fesoʻotaʻiga o fesoʻotaʻiga faʻaoga / fafo.

-Manatua

E mafai ona vaevaeina le manatua i ni vaega se lua: fa'amaumauga fa'amaumauga ma le polokalame manatua.

E fa'aogaina fa'amaumauga fa'amaumauga e teu ai fa'amaumauga ma fa'aogaina le teuina o polokalame e teu ai polokalame ma fa'amaufa'ailoga.

 

- Fa'aulu/Output - Feso'ota'i po'o le aveta'avale masini eseese

Taulaga fesoʻotaʻiga faʻasalalau-faʻamatalaga fefaʻatauaʻiga i le va o le MCU ma isi faʻasalalauga, pei ole UART, SPI, 12C, ma isi.

 

3 Fa'avasegaga microcontroller

I tulaga o le numera o bits, microcontrollers e mafai ona faʻavasegaina i: 4-bit, 8-bit, 16-bit, ma le 32-bit.I faʻatinoga faʻatinoga, 32-bit tala mo le 55%, 8-bit tala mo le 43%, 4-bit tala mo le 2%, ma le 16-bit tala mo le 1%

E mafai ona iloa o le 32-bit ma le 8-bit microcontrollers o microcontrollers sili ona faʻaaogaina i aso nei.
O le eseesega i le numera o bits e le o faʻatusalia ai le lelei poʻo le leaga microprocessors, ae le o le maualuga o le numera o bits e sili atu le microprocessor, ae le o le maualalo o le numera o bits o le leaga o le microprocessor.

8-bit MCUs e tele;latou te ofoina atu polokalame faigofie, malosi malosi ma tamai afifi lapoa (o nisi e na o le ono pine).Ae o nei microcontrollers e le masani ona faʻaogaina mo fesoʻotaʻiga ma fesoʻotaʻiga galuega.

O feso'ota'iga feso'ota'iga masani ma fa'aputuga polokalame feso'ota'iga e 16- po'o le 32-bit.O fesoʻotaʻiga telefoni e avanoa mo nisi masini 8-bit, ae 16- ma 32-bit MCUs e masani lava o le filifiliga sili atu ona lelei.Ae ui i lea, 8-bit MCUs e masani ona faʻaaogaina mo le tele o faʻatonuga, lagona, ma faʻaoga faʻaoga.

Faʻataʻitaʻiga, microcontrollers e mafai ona vaevaeina i ni vaega se lua: RISC (Reduced Instruction Set Computers) ma le CISC (Complex Instruction Set Computers).

O le RISC ose microprocessor e fa'atino ai nai ituaiga o fa'atonuga komepiuta ma na afua mai i le 1980s ma le MIPS mainframe (ie, RISC machines), ma o microprocessors fa'aaogaina i masini RISC e ta'ua fa'atasi RISC processors.I lenei auala, e mafai ona faʻatino gaioiga i se saoasaoa vave (miliona sili atu faʻatonuga ile sekone, poʻo MIPS).Talu ai e mana'omia e komipiuta isi transistors ma elemene ta'amilosaga e fa'atino ai ituaiga fa'atonuga ta'itasi, o le tele o le seti o fa'atonuga komipiuta e fa'alavelave ai le microprocessor ma fa'agasolo lemu.

O le CISC e aofia ai le tele o microinstructions e faʻafaigofie ai le fatuina o polokalame e faʻaogaina i luga o le gaosiga.O fa'atonuga o lo'o faia i le gagana fa'apotopotoga, ma o nisi o galuega masani na fa'atinoina muamua e le polokalame e fa'atinoina e le fa'atonuga o meafaigaluega.O le galuega a le tagata fai polokalame e matua faʻaitiitia, ma o nisi faʻatonuga maualalo poʻo faʻagaioiga o loʻo faʻagasolo faʻatasi i taimi taʻitasi taʻitasi e faʻateleina ai le saoasaoa o le faʻatinoina o le komepiuta, ma o lenei faiga e taʻua o faʻatonuga faʻalavelave.

4 Aotelega

 

O se luʻitau ogaoga mo le au inisinia eletise i aso nei o le fausia lea o se tau maualalo, leai se faʻalavelave, ma e oʻo lava i le tulaga o le toilalo e mafai ona galue ai masini, i le faʻaleleia atili o le taʻavale i le taimi nei, e faʻamoemoeina microcontrollers e faʻaleleia le faʻatinoga. o iunite fa'aeletoroni ta'avale.
