Nooca Wareegga Isku-dhafan

1 Qeexitaanka Microcontroller

Maaddaama uu microcontroller-ku yahay unugga macquulka ah ee xisaabta, xusuusta, saacadda/ xisaabiyaha, iyo wareegyada kala duwan ee O, iwm. oo lagu dhex daray chip-ka, oo ka kooban nidaam dhammaystiran oo xisaabeed, waxaa sidoo kale loo yaqaannaa kombuyuutar-hal-chip ah.

Barnaamijka ku jira xusuusta microcontroller ee si dhow loola isticmaalo qalabka microcontroller iyo wareegyada hardware durugsan, waxaa laga soocay software-ka PC, waxaana loogu yeeraa barnaamijka microcontroller sida firmware.Guud ahaan, microprocessor-ku waa CPU ku jira hal wareeg oo isku dhafan, halka microcontroller uu yahay CPU, ROM, RAM, VO, timer, iwm. dhammaan hal wareeg oo isku dhafan.Marka la barbar dhigo CPU, microcontroller ma laha awood xisaabeed aad u xoog badan, mana laha MemoryManaaement Unit, taas oo ka dhigaysa microcontroller kaliya inay xamili karto qaar ka mid ah kantaroolka fudud oo fudud, macquulka ah, iyo hawlo kale, iyo si balaadhan loogu isticmaalo xakamaynta qalabka, habaynta calaamadaha dareemayaasha. iyo meelo kale, sida qaar ka mid ah qalabka guriga, qalabka warshadaha, qalabka korontada, iwm.

2 Halabuurka microcontroller

Microcontroller-ku wuxuu ka kooban yahay dhowr qaybood: processor-ka dhexe, xusuusta, iyo gelinta/soo-saarka:

processor-ka dhexe:

Processor-yare dhexe waa qaybta xudunta u ah MCU, oo ay ku jiraan labada qaybood ee ugu muhiimsan hawlwadeenka iyo kantaroolaha.

- Hawl-wadeen

Hawlwadeenku waxa uu ka kooban yahay unug xisaabeed & macquul ah (ALU), kaydiyaha iyo diiwaanka, iwm. Doorka ALU waa in uu sameeyo xisaabin ama hawlgallo macquul ah xogta soo socota.ALU waxay awood u leedahay in ay ku darto, ka jarto, isbarbar dhigto, ama isbarbardhigto cabbirka labadan xog, iyo ugu dambayntii ay ku kaydiso natiijada ururiyaha.

Hawlwadeenku wuxuu leeyahay laba hawlood:

(1) Si loo sameeyo hawlo xisaabeed oo kala duwan.

(2) In la sameeyo hawlgallo macquul ah oo kala duwan iyo in la sameeyo imtixaanno macquul ah, sida tijaabada qiimaha eber ama isbarbardhigga laba qiime.

Dhammaan hawlgallada uu sameeyo hawlwadeenku waxaa haga calaamadaha kantaroolka ee kantaroolaha, iyo, halka hawlgalka xisaabtu uu soo saaro natiijada xisaabeed, hawlgal macquul ah ayaa soo saara xukun.

-Koontaroolaha

Kantarooluhu waxa uu ka kooban yahay miiska barnaamijka, diiwaanka tilmaamaha, cod-dejiyaha tilmaamaha, koronto-dhaliyaha wakhtiga iyo kormeeraha hawlgalka, iwm. Waa "hubka go'aaminta" kan soo saara amarrada, ie isku-dubarid iyo haga hawlaha nidaamka microcomputer oo dhan.Shaqadeeda ugu muhiimsan waa:

(1) Si aad tilmaamaha uga soo saartid xusuusta oo aad muujisid meesha tilmaamaha xiga ee xusuusta.

(2) Si loo kala saaro oo loo tijaabiyo tilmaamaha oo loo abuuro calaamada xakamaynta hawlgalka ee u dhiganta si loo fududeeyo fulinta falka la cayimay.

(3) Wuxuu hagaa oo xakameeyaa jihada xogta u dhexeysa CPU, xusuusta, iyo agabka wax gelinta iyo soo saarista.

Microprocessor-ku wuxuu isku xiraa ALU, xisaabiyeyaasha, diiwaan gelinta iyo qaybta kontoroolka iyada oo loo marayo baska gudaha, oo wuxuu ku xiraa xusuusta dibadda iyo wareegyada isdhexgalka / soo-saarka iyada oo loo marayo baska dibadda.Baska dibadda, oo sidoo kale loo yaqaan baska nidaamka, wuxuu u qaybsan yahay xogta baska DB, cinwaanka baska AB iyo baska kantaroolka CB, wuxuuna ku xidhan yahay aaladaha durugsan ee kala duwan iyada oo loo marayo wareegga wax-gelinta/soo-saarka.

-Xusuus

Xusuusta waxa loo qaybin karaa laba qaybood: xusuusta xogta iyo xusuusta barnaamijka.

Xusuusta xogta waxa loo isticmaalaa in lagu kaydiyo xogta iyo kaydinta barnaamijka waxa loo isticmaalaa in lagu kaydiyo barnaamijyada iyo xuduudaha.

 

-Input/Output -isku xidhka ama wadista aaladaha kala duwan

Dekedo isgaarsiineed oo taxane ah-xogta isdhaafsiga u dhaxaysa MCU iyo qaybaha kala duwan, sida UART, SPI, 12C, iwm.

 

3 Kala soocida Microcontroller

Marka la eego tirada bits, microcontrollers waxaa loo kala saari karaa: 4-bit, 8-bit, 16-bit, iyo 32-bit.Codsiyada wax ku oolka ah, 32-bit waxay ku xisaabtamayaan 55%, 8-bit waxay ku xisaabtamayaan 43%, 4-bit xisaabaadka 2%, iyo 16-bit xisaabaadka 1%

Waxaa la arki karaa in 32-bit iyo 8-bit microcontrollers ay yihiin kuwa loogu isticmaalka badan yahay maanta.
Farqiga u dhexeeya tirada bits ma matalo microprocessor-ka wanaagsan iyo midka xun, ma aha tirada sare ee tirooyinka ayaa ka sii fiicnaanaya microprocessor-ka, oo ma aha tirada yar ee tirada yar ee ka sii daraya microprocessor-ka.

MCU-yada 8-bit waa kuwo badan;waxay bixiyaan barnaamijyo fudud, hufnaanta tamarta iyo cabbirka xirmo yar (qaar waxay leeyihiin lix biin oo keliya).Laakiin kantaroolayaashan yar yar ayaa sida caadiga ah loo isticmaalin isku xidhka iyo hawlaha isgaarsiinta.

Nidaamyada shabakadda ee ugu caansan iyo xirmooyinka software-ka isgaarsiinta waa 16- ama 32-bit.Qalabka isgaadhsiinta ayaa diyaar u ah qaar ka mid ah qalabka 8-bit, laakiin 16- iyo 32-bit MCUs ayaa inta badan ah doorashada ugu hufan.Si kastaba ha ahaatee, 8-bit MCU-yada waxaa sida caadiga ah loo isticmaalaa kontorool kala duwan, dareen, iyo codsiyo is-dhexgal.

Qaab dhismeed ahaan, kontaroolayaasha yar-yar ayaa loo qaybin karaa laba qaybood: RISC (Kombuyuutarrada Wax-barashada La dhimay) iyo CISC (Complex Instruction Set Computers).

RISC waa microprocessor-ka fuliya noocyo yar oo tilmaamaha kombuyuutar ah oo asalkiisu ahaa 1980-aadkii MIPS-ga weyn (ie, mishiinnada RISC), microprocessor-yada loo isticmaalo mishiinada RISC waxa si wada jir ah loogu yeedhaa processor-yaasha RISC.Sidan, waxay awood u leedahay in ay ku fuliso hawlgallada si xawli ah (malaayiin tilmaamo dheeraad ah ilbiriqsi kasta, ama MIPS).Sababtoo ah kombuyuutarku waxay u baahan yihiin transistor dheeraad ah iyo xubno wareeg ah si ay u fuliyaan nooc kasta oo tilmaamo ah, inta badan ee habka barashada kombiyuutarku wuxuu ka dhigayaa microprocessor mid adag oo u fuliyaa hawlaha si tartiib tartiib ah.

CISC waxa ku jira habab yar oo qani ah oo fududaynaya abuuritaanka barnaamijyada ku shaqeeya processor-ka.Tilmaamuhu waxay ka kooban yihiin luqadda kulanka, iyo qaar ka mid ah hawlaha caadiga ah ee asal ahaan ay hirgeliyeen software-ka waxaa fuliyaa habka wax-barida qalabka.Shaqada programmer-ka ayaa sidaas darteed aad loo dhimay, qaar ka mid ah hawlgallada ama hawlgallada hoose ayaa si isku mid ah loo farsameeyaa xilli kasta oo wax-barashada si loo kordhiyo xawaaraha fulinta ee kombiyuutarka, waxaana nidaamkan loo yaqaannaa hab-waxbarasho oo adag.

4 Kooban

 

Caqabadda halista ah ee injineerada elektiroonigga ah ee baabuurta maanta ayaa ah in la dhiso qiime jaban, dhib la’aan, iyo xitaa haddii ay dhacdo guuldarro shaqayn karta nidaamyada baabuurta, waxqabadka gaariga ayaa si tartiib tartiib ah u wanaajiya xilligan, microcontrollers ayaa la filayaa inay kor u qaadaan waxqabadka. Unugyada kontaroolada baabuurta.
