Pamodzi ndi purosesa yatsopano ARM inayambitsa purosesa yojambula yopangidwira m'badwo wotsatira wa single-chip system. Mali-G77, zomwe siziyenera kusokonezedwa ndi purosesa yatsopano yowonetsera , ikuwonetsa kusintha kuchokera ku zomangamanga za ARM Bifrost kupita ku Valhall.
ARM yalengeza kuwonjezeka kwakukulu kwa zojambulajambula za Mali-G77 - ndi 40% poyerekeza ndi m'badwo waposachedwa wa Mali-G76. Izi zidatheka kudzera munjira zamaukadaulo komanso kukonza zomangamanga. Mali-G77 akhoza kukhala ndi ma cores 7 mpaka 16 (kukweza kuchokera ku 1 mpaka 32 n'kotheka m'tsogolomu), ndipo aliyense wa iwo ali pafupifupi ofanana ndi G76. Chifukwa chake, mafoni apamwamba amatha kukhala ndi kuchuluka komweko kwa ma GPU cores.
M'masewera, mutha kuyembekezera kusintha kwa magwiridwe antchito pakati pa 20 ndi 40%, kutengera mtundu wazithunzi zojambulidwa. Potengera zotsatira za mayeso odziwika a Manhattan GFXBench, kukwera kwakukulu kwa GPU yatsopano kuposa m'badwo wapano kukakamiza opikisana nawo a Qualcomm kudandaula za kusintha kwakukulu kwa magwiridwe antchito a Adreno.
Pazokha, zomanga zatsopano za Mali-G77 zimapereka kusintha kwapakati pa 30 peresenti pakuchita bwino kwamagetsi kapena magwiridwe antchito, ikutero ARM. M'badwo wachiwiri wa zomangamanga za ARM Valhall zimalola GPU kuchita malangizo 16 pamzere uliwonse molingana ndi CU, poyerekeza ndi eyiti ku Bifrost (Mali-G76). Zatsopano zina zikuphatikiza kuwongolera malangizo oyendetsedwa ndi Hardware komanso malangizo atsopano pomwe mukukhalabe ogwirizana ndi Bifrost. Thandizo la mawonekedwe a compression a ARM AFBC1.3 ndi zina zatsopano (FP16 render targets, layered rendering and vertex shader outputs) nawonso awonjezedwa.
Bifrost CU inali ndi injini zopha 3, iliyonse yomwe inali ndi cache ya malangizo, kaundula, ndi Warp control unit. Kugawidwa m'mainjini atatuwa kunalola kuti malangizo a 24 FMA achitidwe pa 32-bit floating point precision (FP32). Ku Valhall, CU iliyonse ili ndi injini imodzi yokha yophera, yogawidwa pakati pa mayunitsi awiri a compute omwe amatha kukonza malangizo a Warp 16 pa wotchi, zomwe zimapangitsa kuti pakhale 32 FMA FP32 malangizo pa CU. Chifukwa cha kusintha kwa kamangidwe kameneka, Mali-G77 ikhoza kuwerengera gawo limodzi mwa magawo atatu a masamu poyerekezera ndi Mali-G76.
Kuphatikiza apo, iliyonse mwa ma CU awa ili ndi zida ziwiri zatsopano zamasamu. Injini yatsopano yosinthira (CVT) imagwira ntchito zoyambira, zomveka, nthambi, ndi malangizo osinthika. Special Function Unit (SFU) imafulumizitsa kuchulukitsa, kugawa, square root, logarithms, ndi ntchito zina zovuta.
Malo okhazikika a FMA ali ndi zoikamo zingapo zomwe zimathandizira 16 FP32 malangizo pa kuzungulira, 32 kwa FP16, kapena 64 kwa INT8 Dot Product. Kukhathamiritsa uku kungathe kupititsa patsogolo magwiridwe antchito mpaka 60% pamapulogalamu ophunzirira makina.
Kusintha kwina kofunikira mu Mali-G77 ndikuchulukirachulukira kwa magwiridwe antchito a injini, yomwe tsopano imagwiritsa ntchito ma texel 4 pa wotchi iliyonse poyerekeza ndi ma texel awiri am'mbuyo, ma texel 2 atatu pa wotchi, ndikupangitsa kusefa mwachangu kwa FP16 ndi FP32.
ARM yasinthanso zina zambiri, pomwe Mali-G77 ndi Valhall akulonjeza kusintha kwakukulu pamachitidwe amasewera ndi makina ophunzirira makina. Chofunika kwambiri, kugwiritsa ntchito mphamvu ndi malo a chip amasungidwa pamiyezo ya Bifrost, kulonjeza zida zam'manja zomwe zimakhala ndi ntchito yapamwamba kwambiri popanda kuwonjezera kugwiritsa ntchito mphamvu, kutayika kwa kutentha komanso kukula kwakufunika.
