hauv paus ntsiab lus ntawm cov lag luam

Lub cache nco ncaj qha muaj feem xyuam rau cov kev ceev ntawm lub ntau yam hauj lwm, raws li khw muag khoom noj nyob rau hauv ua ntej qhov xav cov ntaub ntawv. Lub hauv paus ntsiab lus ntawm nws cov lag luam yuav tsum tau piav nrog ib tug piv txwv yooj yim. Ib tug neeg twg rau optimize lawv ua hauj lwm ua mus rau qhov chaw nyob rau hauv koj desktop khoom nyob rau hauv ib tug tej yam zajlus kom kev txiav txim. Feem ntau cov yuav, lub tom ntej no yuav lis, xov tooj, yam txoj kev, tam sim no cov ntaub ntawv, thiab thiaj li nyob. D. Nws yog tsis zoo li hais tias ib tug neeg hides txhua txhua lub sij hawm nws yuav tsum tau cov ntaub ntawv rau lub niaj xyoo tshaj qhia tsib lub xyoos dhau los, vim hais tias nws yuav siv sij hawm lub sij hawm thiab kev rau siab. Nws yog nyob rau txoj ntsiab cai no thiab ua hauj lwm cache. Yuav ua li cas qhov no txhais tau nyob rau hauv lub tshuab theem? Nyob rau hauv qhov tseeb, ib tug zoo xws li cov txheej txheem. Tag nrho cov ntaub ntawv muaj nyob rau hauv lub PC mus rau ib tug tej yam hierarchy. Yog hais tias ib co lus qhia no yuav tsum tau ntau tshaj li lwm leej lwm tus, lawv, ntsig txog, yog los ze zog.

theem

Tus thawj Piv txwv li, uas yog koom nyob rau hauv lub me nyuam ntawm cov ntaub ntawv mus rau ib tug processor ntawm ib tug tus kheej lub computer, ua lub cim xeeb. Txawm li cas los, txawm hais tias nws yog ntau lub sij hawm sai tshaj li ib tug disk, nws tsis nco ntsoov cia kom nrog cov kev xav tau kev pab ntawm no nti. Uas yog vim li cas cov ntaub ntawv uas yog siv ntau dua lwm tus, yog pauv mus rau lub thib ob theem cache. Yuav ua li cas yog nws? Nyob rau hauv cov ntaub ntawv no, lub cim xeeb yog nyob rau ntawm ib tug nyias muaj nyias ib nti, ultra-high ceev, uas yog muab tso ze rau hauv lub processor, thiab nyob rau hauv tshiab computers thiab feem ntau kev mus rau hauv lub nti nws tus kheej.

Cov ntaub ntawv siv ntau feem ntau, piv txwv li, tib pab neeg, tsiv mus rau ib tug tshwj xeeb ntawm tes processor thiab pib nws tus kheej cache ntawm cov thawj theem. Qhov no yog tus ceev tshaj cim xeeb nyob rau hauv ib tug tus kheej lub computer.

ib theem zuj zus ntawm kev ua

Sai li sai tau raws li lub processor yuav tsum tau ua ib tug yam hauj lwm, nws ua ntej ntsuam cov ntaub ntawv nyob rau hauv lub register. Yog hais tias cov ntaub ntawv yog tsis muaj, nws hloov mus rau lub cache ntawm cov thawj theem, ces - mus rau lub thib ob-theem cache. Yog hais tias muaj yog ntaub ntawv, dhau lawm, yog nrhiav tsis tau, lub processor hais txog cov RAM. Nyob rau hauv lub kawg version, yog hais tias tus tsim nyog cov ntaub ntawv twb tsis pom nyob qhov twg lwm, tus ntaus ntawv nyeem cov ntaub ntawv los ntawm lub hard drive. Raws li, qhov sim ua ntej lub processor pom qhov tsim nyog cov ntaub ntawv, tus ceev nws yuav ua tau nws cov hauj lwm.

Number of misses thiab hits, thiab qhia txog cov kev ceev ntawm lub CPU nyob rau hauv relation mus rau qhov hauj lwm rau nws.
• cache loj yog ntau me tshaj lub ntsiab cim xeeb los yog muaj peev xwm, uas muaj ib tug nyuaj tsav ntawm koj tus kheej lub computer.
