Yuav ua li cas yog kev kho vajtse acceleration?

Nyob rau hauv niaj hnub lub computer technology kho vajtse acceleration yog siv qhov txhia chaw. Nws tau ua raws li paub thiab tej yam ntuj tso, raws li ib tug extension ntawm CPU MMX cov lus qhia. Tab sis nws tsis yog ib txwm. Tus thawj ceev faj cov kauj ruam developers thiab programmers los txhawb cov tshiab nta, ib tug tov kev ntsuam xyuas ntawm lub computer lub zej zog, thiab ces - paub ... nws yog. Tam sim no, hardware acceleration yog tam sim no nyob rau hauv yuav luag txhua txhua ntaus ntawv thiab cov kev pab cuam. Tej zaum, txawm nyob qhov twg nws thiab tsis txhob nrhiav ib tug siab nyiam. Koj puas xav tau ib tug video card uas txhawb nqa kev kho vajtse acceleration? Thov! A suab card? Yes, kom txaus! Zoo, cov network card? Thiab nws muaj lub peev xwm los offload cov CPU los ntawm niaj hnub ua hauj lwm uas muaj ntaub ntawv packets!

Kho vajtse acceleration yog dav siv nyob rau hauv ntau yam kev pab cuam rau cov zauv multimedia ntws. Vim qhov no nws yog ua tau rau txo tau lub sij hawm siv. Tsis yog txhua tus paub hais tias browser developers tau ntev tau siv rau hauv lawv cov khoom rau hauv lub sij hawm los mus leeb ua hauj lwm nrog graphics (rendering complex nplooj ntawv) los ntawm kev siv ntawm kho vajtse acceleration los ntawm cov yooj yim zog rau daim video card.

Yuav ua li cas hom ntawm acceleration nws? Nyob rau hauv qhov tseeb, txhua yam yog yooj yim. Raws li cov kev tswvyim ntawm lub computer ntaus ntawv, tag nrho cov zauv ua CPU (CPU). Yog li ntawd, pab neeg no xam tus nqi ntawm cov "2 + 2" qhov kev pab cuam yog hloov dua siab tshiab rau lub tshuab code thiab xa nws rau ua. Tab sis raws li txhua ob processor executes ib tug lossis loj tus naj npawb ntawm suav, ces muaj qhov sib ntxiv ntawm ib tug tshiab ua hauj lwm nws cov kev ua tau zoo yog me ntsis txo - lub noob pob kws yog loaded. Developers tau ntev nrhiav kom nce cov kev ceev ntawm lub laij, tsis ua CPU lub hwj chim, thiab cov kev taw qhia ntawm ancillary kho vajtse tuition muab lub sij hawm.

Xav txog tej yam ib tug video card ntawm ib xyoo caum dhau los. Nws yog ib tug logic thiab cov video nco. Tej ntaub ntawv cas muaj feem xyuam rau cov dluab kaw nrog ib tug array ntawm lub cim xeeb hlwb, thiab nyob rau hauv ib txoj kev hloov mus rau hauv ib lub teeb liab "ntshiab" schemes saib xyuas.

Tej kev hloov nyob rau hauv cov duab, txawm tsis tseem ceeb xaav ntawm lub taw tes rau lub keeb kwm yav dhau xim - qhov tshwm sim ntawm cov CPU. Nws yuav tsum coordinates, lub offset thiab lub voj voog yog rov qab. Yog hais tias tus taw tes tsis yog ib tug, tus xov tooj ntawm suav yuav tsub kom. Nyob rau hauv tas li ntawd, lub processor yog twb muaj "yuav ua li cas". Cov - qeeb.
Nyob rau qhov no nyob rau hauv cov video card pib mus rau qhov chaw ib tug tshwj xeeb processor uas yog koom xwb nyob rau hauv graphics, uas tso cai rau dawb pab universal CPU. Ib tug zoo xws li cov txoj kev twb tau muab siv rau lub suab - suab nti "kawm" mus rau leeb ib co ntawm cov yam ntxwv; Network - Adapters tau txais ib tug tshwj xeeb lub hom phiaj processor thiab li ntawd.

Lov tes taw los yog pab kho vajtse acceleration nyob rau hauv daim ntawv thov, koj ua tau, tab sis tsuas yog xws li ib tug feature yog muab los ntawm lub programmer. Piv txwv li, tswj graphics acceleration nyob rau hauv lub qhov rais XP raws li nram no: koj yuav tsum hu cov cuab yeej rau lub desktop thiab ua raws li txoj kev "tej chaw - Advanced - Mob". Lub slider yog nyob rau hauv no qhov rais tso cai rau koj mus tag nrho los yog lov tes taw kho vajtse acceleration ntawm lub tag nrho qhov system. Tej zaum nws yog tsim nyog los daws tau qhov compatibility teeb meem.
