Vs. video zaub processors thiab graphics ua chav nyob

Mar 14, 2019

Qhov sib txawv ntawm cov maub los tso IC (hu ua zaub maub, video saib maub, tso saib cav, zaub processor, zaub interface, etc.) thiab graphics accelerator IC (hu ua 3D engine) ua cov lus teb hais txog 2D lossis 3D rendering (duab cim) thiab IC ua muab xam txog video compression / decompression algorithms yog technically ntawm chav kawm yog lossis loj. Tab sis txij li tag nrho cov ntawm no logic feem ntau pom nyob ntawm tus ntiv tes ntawm ib chav ua haujlwm thiab feem ntau tsis muaj nyias mus rau qhov kawg-qhua muaj ntau yam tsis meej pem txog cov kev ua haujlwm zoo sib xws heev.


VDCs feem ntau muaj kev kho tshwj xeeb rau kev tsim cov "sprites", muaj nuj nqi uas niaj hnub VDP chips tiav nrog lub "Bit Blitter" siv qhov "Blit blit" function .


Ib qho piv txwv ntawm tus qauv video cam yog "VDP2 32-bit keeb kwm yav dhau thiab txav dav hlau video tso processor" ntawm Sega Saturn. Ib qho piv txwv ntxiv yog Cov Kev Txheeb Zej Nruab Loj Zoo (AGA) ntsa uas yog siv rau kev paub duab ntawm cov cim tom qab Amiga computers.


Qhov no hais tias, nws tsis yog txhua nrho meej thaum ib "video nti" yog ib qho "duab tso saib video" thiab thaum nws yog "video tso duab processor". Piv txwv, lub TMS9918 qee zaum hu ua "video displaylerler" thiab qee zaum "video display processor". Txawm li cas los, tus "video display processor" muaj qee lub zog rau "txheej txheem" ntawm cov ntaub ntawv ntawm RAM (sau thaj tsam ntawm RAM piv txwv), thaum lub sij hawm "cov yeeb yaj duab video" tsuas yog kev tswj cov sij hawm ntawm cov video synchronization Pib ntsais koj teeb thiab nkag mus rau RAM video.


Chav tsev ua haujlwm (GPU) mus rau ib kauj ruam ntxiv dua VDP thiab feem ntau kuj txhawb 3D functionality. Nws yog lub nti uas yog tam sim no siv rau hauv cov tshuab hlwb hlau niaj hnub nim no.
