Isixhobo iprosesa, ukuba isebenza njani ngokwenyani

Kweli hlabathi namhlanje xa iprosesa ubuchwepheshe be-computer yenye yeendawo ezisisiseko. Iyunithi central processing - eliphezulu-zobugcisa kunye isixhobo othambe kakhulu, nto leyo equka zonke yenkqubela kwenzeka candelo lezobuchwepheshe computer, ngokunjalo kwiindawo ezikufutshane kuyo.

Lula isixhobo iprosesa sijongeka njengoku:

Isiseko ngumongo (enye okanye ezininzi). Banoxanduva lokuthobela yonke imigaqo bathembela;

Kukho imiphakamo eziliqela efihlakeleyo memory (idla amabini okanye amathathu), apho ibalekisa kumqhubekekisi intsebenziswano kunye RAM;

isilawuli RAM;

Controller system ibhasi (QPI, ht, DMI, njalo njalo).;

izixhobo ulawulo Processor luphawulwa parameters zilandelayo:

Chwetheza microarchitecture;

Amaza clock ;

Amanqanaba cache imemori;

Ubungakanani cache imemori;

Uhlobo kunye nesantya kwindlela ibhasi;

Ubungakanani amazwi ukuqhubekekiswa;

imemori isilawuli Integrated (kungaba);

Chwetheza RAM backed;

Umthamo Idilesi memory;

Nj yemizobo eyakhelwe-ngaphakathi (integrated mifanekiso akuqhelekanga ukuba umhla kwaye isebenza kunokuba nje ukuncedisana ukuba ikhadi enamandla ngakumbi obubobu, nangona isixhobo iprosesa ikuvumela ukuba usebenzise umhle enamandla, izisombululo oludibeneyo);

Isixa umbane osetyenziswayo.

Iprosesa kunye neempawu zayo

CPU core - ngokoqobo intliziyo yakhe, eziquka iiyunithi ezisebenzayo ngethuba esenza ekuqiqeni imisebenzi nasekubaleni. umsebenzi ngolu hlobo lulandelayo kernel:

Block retrieval lukhangelwa ubukho okuphazamisa. Fumana iziphazamiso efanayo, bangena mfumba. counter nkqubo ifumana idilesi ukusuka kwiqela uliqeqeshayo uphazamiso. Xa begqibile imisebenzi umsebenzi angaluphazamisa, idata ivaleleke mfumba buyisa. umyalelo Eminye olufundwa ukusuka zeyunithi idilesi umyalelo isampulu. Ngenxa yoko olufundwa ukusuka RAM okanye cache, ngoko idatha ethunyelwe kwiyunithi kokuhlaziya. Ngoku zokucazulula wemiyalelo ezifunyenweyo ke idluliselwe sampling Unit data. Apho, i data wayifunda RAM okanye cache imemori mazigqithiselwe lomcwangcisi, nto leyo ichaza ukuba izakuba ngowuphi unit kufuneka enze msebenzi, ngoko ke idatha enikezwe kuyo. Iyunithi yolawulo imiyalelo isebenzise imiyalelo ezifunyenweyo, kwaye edlulisela ngesiphumo ibhloko ukugcina iziphumo.

Lo mjikelo ngokuba inkqubo, kwaye imiyalelo gqolo babulawa ezi program. Kuba izinga apho omnye ibakala umjikelo ukuya komnye, ekwafanekisa le frequency iwotshi, yaye ekuhambeni kwexesha, lo walivala ithende ngenxa inyathelo kumjikelo umsebenzi, unoxanduva isixhobo iprosesa ngokwalo, okanye mandithi yaseburhulumenteni.

Kukho iindlela ezininzi apho unako ukuphucula ukusebenza kumqhubekekisi. Ukuze wenze oku, kufuneka anyuse umgangatho ngaashi, leyo yimida ethile. Ngokuqinisekileyo Ukwandisa amaza iwashi kwandisa ukusetyenziswa kwamandla kunye, ngenxa yoko, ubushushu, kwaye oku kukhokelela ekuncipheni uzinzo yonke unit iprosesa.

Ukwenzela ukuphepha imfuneko yokwandisa amaza iwotshi, abalimi bagqiba ukuya kwenye indlela, eza kunye ezahlukeneyo izisombululo ngobugcisa. Esinye isisombululo okunjalo yombhobho, eli leyo kukuba komyalelo ngamnye processing wabulawa khosi kunikwa zonke Iibhloko ngumongo, oluqhutywa ngenyathelo. Ngoko, xa imiyalelo yonke yomsindo uninzi iibhloko ziya kuba kwimo bengasebenzi. Ngoko ke, zonke abaqhubekekisi mihla ukusebenza ngolu hlobo: ngokwenza msebenzi mnye, bathi ukuqhubeka ngoko nangoko komnye, enciphisa kwemitshini kubuncinane nokwandisa ukusebenza nge kangangoko kunokwenzeka. Kakade ke, ngokuyinene, kubonakala ukuba icebo iprosesa usoloko usebenza nge-100 ngempumelelo%, kodwa oko akwenzeki ngenxa yokuba bekukho ukuba kubekho iqela azingqinelani.
