A tsakiyar aiki naúrar - a kai

The aiki na kowace kwamfuta da aka bayar tare da daya kananan na'urar (guntu), wanda aka sani a matsayin tsakiyar aiki naúrar. Wannan silicon substrate da ma gaba daya a ta yadudduka dauke da tsarin abubuwa: wani ilmin lissafi dabaru naúrar (data aiki), da iko naúrar (for kayyade domin na kisa na dokokin), rajista (for data ajiya), ciki cache (ga sauri sadarwar da RAM memory), da ciki bas (for watsa bayanai tsakanin aikin raka'a na processor), da dai sauransu

CPU, ko kuma wajen da Agogon mita kayyade gudun dukan tsarin. Samar da wani Agogon mita aiki tare, Ina nufin daidaito raba tubalan cikin processor na aikin da kuma bayan. Modern sarrafawa for sirri kwakwalwa, wannan halayyar ne 'yan gigahertz (GHz), wanda ke nufin cewa shi ne iya yi Multi-biliyan na farko ayyukan da na biyu. Har ila yau, to ainihin halaye na processor ne bit, da ciki juz'i na cache memory, da yawan nuclei soket.

Don samar da ake so yi na kwamfuta shi ne na farko zama dole don zaɓar CPU daidai. Ka yi la'akari da wannan na'urar a cikin daki-daki. Daban-daban na sarrafawa ciki gine, misali, emit na'ura mai da superscalar sarrafawa. A farko karuwa yawan aiki ta hanyar rabuwa aiwatar aiwatar da umarni a kan raba matakai, cikinsa da processor lokaci guda tafiyar matakai da dama teams a matakai daban-daban. A mafi bututun, saukarwa a cikin mafi girma Agogon kudi da kuma, daidai da, yawan aiki. Amma kawai a cikin dalilin.

A CPU ne don haka mai suna saboda shi ne babban sarrafa kwamfuta da na'urar a cikin kwamfuta, amma ba daya kawai. Bayan shi zama a cikin tsarin masu kula da daban-daban na'urorin kuma musaya, da kuma sarrafawa for video da aiki, audio, da dai sauransu.

Da farko da kwamfuta da aka ɗauki cikinsa, kuma Ya halitta kawai a matsayin inji for sarrafa kwamfuta, don haka da CPU ne "alhakin" ga duk matakai a cikin tsarin: shigar da bayanai aiki (ilmin lissafi rikirkida), da fitarwa bayanai.
