Simultaneous multithreading (SMT) yog ib txheej txheem rau kev txhim kho tag nrho cov efficiency ntawm superscalar CPUs nrog hardware multithreading. SMT tso cai ntau kev ywj pheej threads ntawm kev ua kom zoo dua siv cov peev txheej muab los ntawm niaj hnub processor architectures.

Yog li ntawd, plaub lub hom phiaj CPU sau npe yog dab tsi?

Muaj plaub lub hom phiaj sau npe uas yog AX, BX, CX thiab DX. Txhua tus tuaj yeem siv los tswj tag nrho 16-ntsis lo lus lossis nrog ob qhov sib cais 8-ntsis bytes. Cov bytes no hu ua qis thiab sab sauv txiav txim bytes.

Tom qab ntawd, lo lus nug yog, hom dab tsi ntawm lub qhov (socket) siv Intel processors? Lub PGA pob yog siv los ntawm Intel Xeon® processor , uas muaj 603 pins. PPGA luv luv rau Yas Pin Grid Array, thiab cov no processors muaj pins uas tau muab tso rau hauv ib lub qhov (socket) ..

Kuj kom paub yog, qhov twg cache ntawm CPU siv ua ntej?

Ntau theem caches feem ntau ua haujlwm los ntawm kev kuaj xyuas qhov ceev tshaj plaws, qib 1 (L1) cache ua ntej ; yog nws hits, lub processor ua tiav ntawm kev kub ceev. Yog tias me dua cache nco, tus ceev tshaj tom ntej cache (theem 2, L2) raug kuaj xyuas, thiab lwm yam, ua ntej nkag mus rau lwm lub cim xeeb.

Dab tsi ntawm RAM suav nrog cache?

Nco Caching A nco cache , qee zaum hu ua a cache khw los yog RAM cache , yog ib feem ntawm nco ua los ntawm high-speed static RAM (SRAM) es tsis txhob qeeb thiab pheej yig dua dynamic RAM (DRAM) siv rau lub ntsiab nco . Nco caching muaj txiaj ntsig vim tias feem ntau cov kev pabcuam nkag mus rau tib cov ntaub ntawv lossis cov lus qhia ntau dhau.
