ARM kuulutab v\u00e4lja m\u00e4rkimisv\u00e4\u00e4rset graafika j\u00f5udluse kasvu Mali-G77 puhul \u2014 40% v\u00f5rreldes praeguse Mali-G76 p\u00f5lvkonnaga. See on saavutatud nii protsessitehnoloogia kui ka arhitektuursete t\u00e4iustuste kaudu. Mali-G77 v\u00f5ib sisaldada 7 kuni 16 tuuma (tulevikus on v\u00f5imalik skaleerimine 1-st kuni 32-ni), kusjuures iga\u00fche suurus on peaaegu sama nagu G76-l. Seet\u00f5ttu varustatakse t\u00f5en\u00e4oliselt k\u00f5rge j\u00f5udlusega nutitelefone sama arvu GPU tuumadega.<\/p>\n

\"Graafikaprotsessor<\/p>\n

M\u00e4ngudes v\u00f5ib ootusp\u00e4rast taset t\u00f5usu oodata 20 kuni 40% ulatuses, olenevalt graafilistest koormustest. Populaarse Manhattan GFXBench testi tulemuste p\u00f5hjal sunnib uue graafikaprotsessori m\u00e4rgatav \u00fclemuslikkus praeguse p\u00f5lvkonna \u00fcle konkurenti Qualcomm'i muretsema Adreno graafika j\u00f5udluse m\u00e4rkimisv\u00e4\u00e4rse paranemise p\u00e4rast.<\/p>\n

ARM-i s\u00f5nul pakub uus Mali-G77 arhitektuur keskmiselt 30-protsendilist energiat\u00f5hususe v\u00f5i j\u00f5udluse paranemist. Teise p\u00f5lvkonna ARM Valhall skalaari arhitektuur v\u00f5imaldab graafikaprotsessoril t\u00e4ita s\u00fcnkroonselt 16 k\u00e4sku ts\u00fckli kohta CU-l, v\u00f5rreldes kaheksa Bifrostis (Mali-G76). Muud uuendused h\u00f5lmavad t\u00e4ielikult riistvara juhtimist d\u00fcnaamilise k\u00e4skude planeerimisega ning t\u00e4iesti uut k\u00e4skude kogumit, mis s\u00e4ilitab tagasip\u00f6\u00f6rdumise \u00fchilduvuse Bifrostiga. Lisatud on ka ARM AFBC1.3 kompressiooniformaadi tugi ning muid uuendusi (FP16 render targets, layered rendering ja vertex shader outputs).<\/p>\n

Bifrost CU sisaldas 3 k\u00e4su t\u00e4itmise mootorrati, millest iga\u00fchel oli k\u00e4skude vahem\u00e4lu, register ja Warp kontroller. Selline jaotus v\u00f5imaldas t\u00e4ita 24 FMA k\u00e4sku 32-bitise floti t\u00e4psusega (FP32). Valhallis on igal CU-l vaid \u00fcks k\u00e4su t\u00e4itmise mootorratas, mis jagatakse kahe arvutusmooduli vahel, mis suudavad iga taktiga t\u00f6\u00f6delda 16 Warp k\u00e4sku, tagades seega 32 FMA FP32 k\u00e4sku CU kohta. T\u00e4nu nendele arhitektuurilistele muudatustele suudab Mali-G77 paralleelsetes arvutustes teostada kolmandiku v\u00f5rra rohkem matemaatilisi arvutusi v\u00f5rreldes Mali-G76-ga.<\/p>\n

\"Graafikaprotsessor<\/p>\n

\"Graafikaprotsessor<\/p>\n

Lisaks sisaldab iga\u00fche neist arvutusmoodulitest CU kahte uut matemaatilist funktsionaalplokki. Uus muunduriplokk (CVT) t\u00f6\u00f6tleb p\u00f5hilisi t\u00e4isarvulisi, loogilisi, harutamis- ja muundurite k\u00e4ske. Erifunktsioonide plokk (SFU) kiirendab t\u00e4isarvude korrutamise, jagamise, ruutjuure, logaritmide ja muude keeruliste t\u00e4isarvufunktsioonide tehingute sooritamist.<\/p>\n

\"Graafikaprotsessor<\/p>\n

\"Graafikaprotsessor<\/p>\n

Tavalises FMA plokis on mitmeid seadeid, mis toetavad 16 FP32 k\u00e4su t\u00e4itmist ts\u00fckli kohta, 32 FP16 v\u00f5i 64 INT8 Dot Product. Need optimeerimised v\u00f5ivad pakkuda kuni 60% suurenenud j\u00f5udlust masin\u00f5ppetehnoloogiates.<\/p>\n

\"Graafikaprotsessor<\/p>\n

\"Graafikaprotsessor<\/p>\n

Teine oluline muudatus Mali-G77-s on tekstuurimooduli j\u00f5udluse kahekordistamine, mis n\u00fc\u00fcd t\u00f6\u00f6tleb 4 bilineaarset tekstuuri ts\u00fckli kohta v\u00f5rreldes varasemate kahega, 2 trilineaarset tekstuuri ts\u00fckli kohta, pakkudes kiiremat FP16 ja FP32 filtreerimist.<\/p>\n

\"Graafikaprotsessor<\/p>\n

\"Graafikaprotsessor<\/p>\n

ARM on teinud ka mitmeid muid muudatusi, mis lubavad Mali-G77 ja Valhalli jaoks olulist j\u00f5udluse kasvu m\u00e4ngukoormustes ja masin\u00f5ppe \u00fclesannetes. Oluline on m\u00e4rkida, et energiatarve ja kiibi pindala on s\u00e4ilinud Bifrosti tasemel, mis lubab pakkuda mobiilseid seadmeid, mille tipptasemel j\u00f5udlus on k\u00f5rgem, ilma energiatarbe, jahutuse ja suuruse n\u00f5udmiste t\u00f5usuta.<\/p>\n
