CPU evoruzhinji - huru vabatsiri

The processor zvinoreva nhamba mudziyo chirongwa raitungamirirwa uye nokuda processing ruzivo. Uropi rinoitwa maererano chirongwa zvakafanorongwa. Chaizvoizvo, izvi ndizvo sezvinotevera: Kana iwe kumhanya chirongwa kupinda RAM, uye ipapo mumwe chikwata pashure mumwe anouya processor. Kuwedzera mirayiridzo kadambari zvinodiwa uye zvimwe data, izvo zvinogona kuuya kana zvakananga nomusoro uye kubva nechitarisiko namano.

Somugumisiro imwe chikwata kuwana Izvi zvinofanira kuchengetwa imwe nzvimbo. Zvino kune mbiri zvokusarudza - kutumira mugumisiro mundangariro kana kusiya mumukadzi processor, sezvo riri zvichida, ichi mugumisiro haisi wokupedzisira uye richashandiswa zvimwe Masvomhu. Muchiitiko chokutanga pane imwe huru "HO" - in exchanges dzakadaro nendangariro rakadini rebei uye, saka, kunoderedza hurongwa unongotaura. Kana yechipiri, processor anofanira ane mu nechivako yavo inonzi ndangariro okunze - the processor evoruzhinji. Ava namano kuti vanoshumira kuti kugamuchira, kuchengeta uye kuparadzira multi-ikakuruma binary mashoko. CPU evoruzhinji vari rakakamurwa mhando mbiri: mukuru-chinangwa evoruzhinji uye chinokosha evoruzhinji.

General chinangwa zvenhoroondo processor yaishandiswa kuchengeta zvenguva migumisiro Masvomhu. The zvimwe zvenhoroondo izvi mukati processor, saka kashoma anotaura gondohwe, ndiko, usapedza nguva pamusoro payo, uye saka havazotadzi unongotaura. Asi kune rumwe ruoko nhamba evoruzhinji ndeyevanyori munzvimbo processor achifa. kuwedzera nhamba yavo havagoni kuva ziendanakuenda. Evoruzhinji kuchengeta data, kazhinji vane vanokwanisa akaenzana date bhazi upamhi. Mumwe remazita processor ane zita rayo rakasiyana nemamwe pachake nako kunyoresa anogona kuwanikwa kuburikidza bumbiro.

Mumwe nomumwe anokosha evoruzhinji ane chinangwa chaicho. Somuenzaniso, pane mazita kuchengeta murayiridzo kero mundangariro kuti verenga unotevera kero. remazita ichi anonzi - mirayiridzo kero remazita. Mumwe muenzaniso womumwe unyanzvi evoruzhinji - ichi chizenga kunyoresa. Mune imwe nzira, kunonzi chinzvimbo shoko processor (Processor ari Status Shoko -. Pfupi PSW). Kusiyana nezvimwe zvose CPU zvenhoroondo, zviri izvo runoonekwa seboka, mumwe vachitova chizenga mazita ane rakasiyana zita uye imwe nzvimbo. Pakati unhu somuenzaniso zvikwanisike govera inonzi chiratidzo ane razero (wemasaini razero mugumisiro). Kana somugumisiro timu kuwana razero Saka processor vanogona 'kudzidza "nezvazvo, ongorora zvishoma vanoti kunyoresa.

CPU evoruzhinji vari kuyeuka yokutsanya chaizvo (dzichimhanya kupfuura cache ndangariro), sezvo vari yepakarepo pedyo ane kadambari neerekitironi anoshanda wachi kakawanda pakati CPU womukati bhazi.
