Qib ntawm CPU Cache:

  • L1 Cache . L1 cache nyob hauv txhua lub hauv paus.
  • L2 Cache . L2 cache loj dua thiab qeeb dua L1 cache .
  • L3 Cache . Nws yog tus loj tshaj cache andresided sab nraum lub hauv paus.
  • Intel® Core™ i7–4770S processor . Intel® Core™ i7–4770S processor Internal Diam duab.
  • Ntaus tus nqi thiab Miss tus nqi.

Ntawm no, qhov loj tshaj cache nco yog dab tsi?

L3 (Qib 3) cache yog cov loj tshaj cachemory unit, thiab kuj yog qhov qeeb tshaj plaws. Nws muaj peev xwm nyob nruab nrab ntawm 4MB mus txog 50MB.

Cache loj npaum li cas cuam tshuam rau CPU kev ua tau zoo? Qib 2 (L2) cache muaj qhov loj nco loj thiab yog siv los khaws cov lus qhia tam sim ntawd. L2/L3 cache plays qhov loj tshaj plaws hauv kev txhim kho cov kev ua tau zoo ntawm cov processors. Qhov loj dua cachesize , qhov ceev cov ntaub ntawv hloov lwm lub tsev thiab qhov zoo dua qhov CPU kev ua tau zoo . Txawm li cas los xij, cache yog kim heev.

Dhau li ntawd, dab tsi yog qhov loj tshaj thiab qeeb cache?

L1 cache yog cov ceev tshaj plaws thiab tsawg tshaj plaws; L2 yog loj dua thiab qeeb dua , thiab L3 ntau. L1 caches aregenerally ntxiv faib rau hauv kev qhia caches thiab cov ntaub ntawv, lub npe hu ua "Harvard Architecture" tom qab relay raws li HarvardMark-1 computer uas qhia nws.

Puas yog CPU cache tseem ceeb?

A CPU cache yog hardware cache siv los ntawm qhov chaw ua haujlwm hauv nruab nrab ( CPU ) ntawm lub khoos phis tawj kom txo qis tus nqi nruab nrab (lub sijhawm lossis lub zog) kom nkag mus rau cov ntaub ntawv los ntawm lub ntsiab lus tseem ceeb. A cache yog lub cim xeeb me me, nrawm dua, nyob ze dua a processor core, uas khaws cov ntawv theej ntawm cov ntaub ntawv los ntawm kev siv lub cim xeeb loj.
