Ib yam li ntawd, tej zaum koj yuav nug, dab tsi yog txhais los ntawm cov kav xa dej?

Hauv kev tsim cov kav dej hauv computer processors, a kav khw yog qhov ncua sij hawm ntawm kev ua raws li cov lus qhia txhawm rau daws qhov teeb meem. Nws kuj cov khw cov lus qhia nyob rau hauv lub fetch theem, los tiv thaiv cov kev qhia nyob rau hauv lub theem ntawm tsis tau overwritten los ntawm cov kev qhia tom ntej nyob rau hauv qhov kev pab cuam.

Kuj Paub, dab tsi yog pipelined architecture? Cov kav dej yog tus txheej txheem ntawm accumulating kev qhia los ntawm lub processor los ntawm a cov kav dej . Cov kav dej yog ib qho txheej txheem uas ntau cov lus qhia sib tshooj thaum ua tiav. Cov kav dej tau muab faib ua cov theem thiab cov theem no txuas nrog ib leeg los tsim cov yeeb nkab zoo li cov qauv.

Qhov thib ob, qhov cuam tshuam ntawm lub kav dej yog dab tsi?

Vim cov kav dej txo cov processor qhov nruab nrab cov lus qhia dhau los, lawv nce lub sij hawm uas nws yuav siv los ua qhov kev pab cuam tam sim no.

Dab tsi yog pipeline npuas thiab cov ntaub ntawv txaus ntshai?

Cov ntaub ntawv txaus ntshai ntxig a lub raj xa dej npuas Thaum twg qhov kev nyeem ntawv tom qab sau ntawv (RAW) tau ntsib, lav kom nce latency, lossis. siv qhov kev txiav txim tawm ntawm kev txiav txim kom muaj peev xwm tiv thaiv qhov xav tau pipeline npuas . siv operand forwarding mus siv cov ntaub ntawv los ntawm cov theem tom ntej nyob rau hauv lub cov kav dej.
