Iprosesa ephakathi iyisici esiyinhloko nesibaluleke kakhulu ohlelweni. Siyabonga kuye, yonke imisebenzi ehlobene nokudluliswa kwedatha, ukukhishwa komyalo, ukusebenza okunengqondo nokusebenza kwamathekisthi kwenziwa. Abasebenzisi abaningi bayazi ukuthi yi-CPU, kodwa abaqondi ukuthi isebenza kanjani. Kulesi sihloko sizozama ukuchaza ngokucacile nangokucacile ukuthi i-CPU ekhompyutheni isebenza kanjani nokuthi yini.
Iprosesa yekhompyutha
Ngaphambi kokuba uhlukanise izimiso eziyisisekelo ze-CPU, kuyadingeka ukuthi ujwayele izingxenye zalo, ngoba akuyona nje ipuleti elingamacandechunge, elifakwe ebhodini le-motherboard, kuyisisetshenziswa esiyinkimbinkimbi, esakhiwe ezicini eziningi. Ungafunda kabanzi mayelana nedivayisi ye-CPU esihlokweni sethu, futhi manje ake siye phansi isihloko esiyinhloko salesi sihloko.

Ukusebenza kwenziwa
Ukusebenza kuyisenzo esisodwa noma eziningana ezicutshungulwayo futhi zenziwa ngamakhompyutha wekhompyutha, kufaka phakathi iprosesa. Imisebenzi ngokwazo ihlukaniswe yaba amakilasi amaningana:
- Ukufaka nokuPhuma. Amadivaysi angaphandle angaphandle, njengekhibhodi negundane, ahlotshaniswa kukhompyutha. Zixhumene ngokuqondile neprosesa futhi umsebenzi ohlukile wabiwe zona. Yenza ukudluliswa kwedatha phakathi kwama-CPU namadivaysi omsakazo, futhi kubangela izenzo ezithile ukubhala ulwazi kwimemori noma ukuyikhiphela kwimishini yangaphandle.
- Ukusebenza kwesistimu banesibopho sokuvimba ukusebenza kwesofthiwe, ukuhlela ukucubungula idatha, futhi ngaphezu kwakho konke, banomthwalo wokusebenza okuzinzile kwesistimu ye-PC.
- Bhala futhi ulayishe imisebenzi. Ukudluliswa kwedatha phakathi kweprosesa nenkumbulo kwenziwa ngokusebenzisa ukusebenza kwepelisi. Isivinini sinikezwa ngokurekhoda ngesikhathi esisodwa noma ukulayishwa kwamaqembu emiyalo noma idatha.
- Ukuqondisisa kwe-Arithmetic. Lolu hlobo lokusebenza lubalwa amanani wemisebenzi, linesibopho sokucubungula izinombolo, ukuguqula zibe izinhlelo ezihlukahlukene zokubala.
- Izinguquko. Ngenxa yokuguqulwa, ijubane lenqubo landa kakhulu, ngoba likuvumela ukuba udlulisele ukulawula kunoma yiliphi iqembu lezinhlelo, ngokuzimela ngokuzikhethela izimo zokuguquka ezifanele.
Yonke imisebenzi kufanele isebenze ngesikhathi esisodwa, ngoba ngenkathi umsebenzi wesistimu izinhlelo eziningana ziqaliswa ngesikhathi esisodwa. Lokhu kwenziwa ngenxa yokushintshaniswa kwedatha yokucubungula ngeprosesa, okuvumela ukuba ubeke phambili imisebenzi futhi uyenze ngokufana.
Yenza ukukhishwa
Ukuqhutshwa komyalo kuhlukaniswe izingxenye ezimbili - ukusebenza nokusebenza. Isigaba sokusebenza sikhombisa yonke isimiso okufanele sisebenze okwamanje, futhi i-operand yenza okufanayo, kuphela ngokuhlukana neprosesa. Imiyalo ibulawa nge-kernel, futhi izenzo zenziwe ngokulandelana. Okokuqala, isizukulwane senzeke, khona-ke ukucaciswa, ukukhishwa komyalo uqobo, isicelo sememori nokulondoloza komphumela ophelile.
Ngenxa yokusebenzisa imemori ye-cache, ukukhishwa kwemilayezo kuyashesha, njengoba kungekho sidingo sokufinyelela njalo RAM, futhi idatha igcinwa emazingeni athile. Izinga ngalinye lememori ye-cache lihlukile kumthamo wedatha nokulayisha nokubhala isivinini, esithinta ijubane lezinhlelo.
Ukusebenzisana kwememori
I-ROM (i-persistent Storage Device) ingagcina ulwazi olungenakuguquleka ngokwayo, kodwa i-RAM (i-Random Access Memory) isetshenziselwa ukugcina ikhodi yohlelo, idatha ephakathi. Iprosesa ixhumana nalezi zinhlobo ezimbili zememori, zicela futhi zithumele ulwazi. Ukusebenzisana kwenzeka ngokusebenzisa amadivaysi angaphandle angxhunyiwe, amabhasi ekheli, ukulawula kanye nabalawuli abahlukahlukene. NgokweSikimu, zonke izinqubo zikhonjisiwe kumfanekiso ngezansi.
Uma uqonda ukubaluleka kwe-RAM ne-ROM, ungenza ngaphandle kokuqala uma idivayisi yokugcina engapheli inememori eminingi, okwamanje engenakwenzeka ukuyisebenzisa. Ngaphandle kwe-ROM, uhlelo ngeke lukwazi ukusebenza, ngeke luqale ngisho, ngoba imishini ihlolwe kuqala ngemilayezo ye-BIOS.

Ukusebenza kwe-CPU
Amathuluzi ejwayelekile we-Windows akuvumela ukuba ulandelele umthwalo ku-processor, ukuze ubone yonke imisebenzi nezinqubo ezenziwe. Lokhu kwenziwa ngokusebenzisa Isiphathi Somsebenziokubangelwa ukushisa Ctrl + Shift + Esc.
Esigabeni "Ukusebenza" ibonisa ukulandelana kwesikhathi komthwalo ku-CPU, inani lezintambo nezinqubo ezisebenzayo. Ngokungeziwe, i-kernel engekho i-paged futhi ilayishiwe imemori iboniswa. Ewindini "Ukuqapha Imithombo" kukhona ulwazi oluningiliziwe mayelana nenqubo ngayinye, amasevisi okusebenza kanye namamojula ahlobene aboniswa.
Namuhla sibuyekeze isimiso sokusebenza kwesevisi yamuva yekhomputha yekhompyutha ngokuningiliziwe kanye nokuningiliziwe. Kuqondwa ngemisebenzi namaqembu, ukubaluleka kwento ngayinye ekubunjweni kwe-CPU. Sithemba ukuthi lolu lwazi luwusizo kuwe futhi ufunde okuthile okusha.
