CPU amarejista - abasizi main

Processor eyenani device uhlelo elawulwa futhi ngokucubungula ulwazi. Ukuhlela nokuqokelela ulwazi wenziwa ngokuhambisana uhlelo kusengaphambili. Empeleni, le nqubo simi ngale ndlela: Uma uhlelo ku-RAM, bese omunye ithimba ngemva kwenye kuziwa processor. Ngaphezu imiyalo Computing izidingo kanye idatha eningi, okuyinto kungavela noma ngokuqondile inkumbulo futhi kusukela kumadivayisi angaphandle.

Ngenxa yalokho lomunye ithimba uthole yi okumelwe ligcinwe endaweni ethile. Futhi ke kukhona ezimbili ongakhetha kukhona - ukuthumela yi kumemori noma ulishiye ngaphakathi processor, njengoba kungenzeka, lokhu yi akuyona wokugcina futhi izosetshenziswa izibalo olwengeziwe. Esimweni sokuqala kukhona eyodwa enkulu "HO" - e ukushintshisana okunje inkumbulo wasebenzisa isikhathi eside, futhi ngenxa yalokho, kunciphe ukusebenza uhlelo. Esimeni sesibili, wokugaya kumele aqukethe e isakhiwo sabo ngokuthi inkumbulo izakhi - ezincwadini processor. Lezi amadivayisi ukukhonza ukuthola, ukugcina bese bedlulisela multi-bit kanambambili idatha. CPU amarejista zihlukaniswe izinhlobo ezimbili: jikelele-njongo amarejista kanye nesitayela ekhethekile.

Jikelele injongo amarejista iprosesa asetshenziselwa ukugcina imiphumela Lesisemkhatsini izibalo. Lapho lezi amarejista ngaphakathi processor, ngakho-ke akuvamile libhekisela Ram, ukuthi, ungachithi isikhathi kuso, futhi ngenxa yalokho akaphelelwa ukusebenza. Kodwa ngakolunye uhlangothi inani amarejista kukhawulwe indawo die processor. ukwandisa isibalo sabo ayikwazi ukungabi. Regista ukugcina idatha, ngokuvamile ibe nomthamo ilingana nobubanzi idatha ibhasi. Ngamunye processor irejista unegama yaso ehlukile enhle ngalo ukubhalisa lungatholakala ngokusebenzisa ikhodi.

Ngamunye ezincwadini ekhethekile unenjongo ekhethekile. Ngokwesibonelo, kukhona irejista ukugcina ikheli imfundo kumemori ukuba ufunde ekhelini elilandelayo. Lokhu irejista libizwa - irejista ikheli imfundo. Esinye isibonelo amarejista ezikhethekile - le mfanelo ukubhalisa. Ngenye indlela, ibizwa ngokuthi isimo izwi processor (Processor Isimo iZwi -. PSW iDemo). Ngokungafani nazo zonke ezinye CPU usomqulu, okuqukethwe okuyinto kubhekwa iyonke, kancane irejista ngemfanelo ngayinye Unegama elikhethekile kanye endaweni eyodwa. Phakathi izichasiso isibonelo kungenzeka ukwaba okuthiwa zero uphawu (ngemvume zero yi Chile). Uma ngenxa iqembu uthole zero yalokho, processor kungaba "funda" ngakho, ehlaziya kancane attribute ukubhalisa.

CPU amarejista inkumbulo fast kakhulu (ngokushesha kunokuba inkumbulo isilondolozi), njengoba ku eduze ngokushesha nucleus Computing futhi sisebenze ngesikalo imvamisa iwashi we-CPU ibhasi yangaphakathi.
