Iwo magiraidhi makadhi (kana GPU) emafoni terminals ane Android ari kuwedzera kukosha kana zvasvika pakuyera mashandiro avo, sezvo maitiro kana uchitamba mitambo zvinoenderana neizvi - kunyanya kana iine matatu-dimensional girafu uye, zvakare, yezviri nani kana zvakanyanya. manejimendi emifananidzo inoratidzwa pachiratidziri. Icho chokwadi ndechekuti modhi nyowani inobata pamusika: ARM Mali-G71. Tichakuudza zvese nezvechikamu ichi.
Iyi GPU yaive mberi kweMali yazvino (T880, inogona kuwanikwa mumidziyo yakaita seye Galaxy S7, neExynos processor yayo), saka inotsvaga kuwedzera mashandiro uye, hongu, kuderedza kushandiswa. Uye, nokuda kweizvi, chivakwa chitsva chakaverengerwa, chinonzi Bifrost - Kusiya shure, saka iyo inonzi Midgard-. Naizvozvo, mazita ane nongedzero kungano dzeNorse anochengetwa.
Mune chaiyo yekuvandudza data, kambani yakazivisa kuti iyo ARM Mali-G71 iri 20% inoshanda zvakanyanya muchikamu chesimba -mubvunzo dzinoitwa pasi pemamiriro akafanana pane neT880-, saka mabhatiri haanyanye kumhanya. Uyezve, kugona kwavo kubata ruzivo zvakare kuri pamusoro, vakamira pa40%. Nekudaro, zvinogoneka kuti nzvimbo diki iyo maGPU ane mukati me processors inoshandiswa zvirinani uye inotaura nezvebasa rakanaka chaizvo nemugadziri uye mugadziri.
Izvi zvinoitwa sei?
Zvakanaka, kuwedzera zvinhu zvakakosha zvinoumba kadhi yemifananidzo kana uchishanda, se "cores shader". Izvi zvakabva ku16 yemhando yemazuva ano kusvika ku32, iyo inowedzera simba rayo uye simba rekushanda. Zvimwe zvakakosha zveiyo ARM Mali-G71 nyowani ndeyekuti inobvumira kushanda ne 120 Hz yakawanda frequency -ideal for virtual reality environments- uye, mukuwedzera, inokwanisa kushanda ne4K resolutions uye kugadzira akawanda-sample mhando yekuderedza muganhu (anti-aliasing). Padhuze uye padhuze nemitambo consoles, hapana kupokana.
Sezvo zvisingaite neimwe nzira, iyo ARM Mali-G71 inoenderana neAPI rinoputika -izvo zvichave zvakakosha munguva pfupi iri kutevera yenharembozha nekusunungura maCPU ebasa-. Mukuwedzera, inosanganisira teknolojia CoreLink CCI-550, iyo inobvumira kadhi yemifananidzo uye processor cores kushandisa chiyeuchidzo chimwechete, iyo inoderedza nguva yekushanda ne data (kuwedzera kushanda ne 1,5 kana ichienzaniswa neT80).
Quad Vectorization uye nezvimwe
Ichi ndicho chimwe chezvakanakisa zveArM Mali-G71 GPU, sezvo ichibvumira basa mukutenderera kwewachi kuti riitwe nekumhanya kukuru pasina kurasikirwa nekugadzikana kana kuwedzera tembiricha. Zvinoreva izvi ndezvekuti kusikwa kwegiraidhi mumativi matatu (X, Y uye Z axes) kunoitwa kare, izvo zvinofarirwa kuti kushanda kwacho kwakawanda. nekukurumidza. Nokudaro, huwandu hwemashoko hunotungamirirwa kare, hunokosha kune madhigirii epamusoro.
Imwe tekinoroji inoshandiswa neARM Mali-G71 inonzi Quad Manager. Nekufambira mberi uku, mirairo inoitwa inoiswa mumapoka nenzira inobudirira, kuitira kuti kuunganidza kwavo uye kutumira kunotevera kuchiratidziro kuve nyore kune hardware uye, naizvozvo, kugadzikana kwakanyanya uye kushandiswa kwesimba kwakaderera. Pamusoro pezvo, mimvuri uye zvimwe zvepamberi mhedzisiro inofarirwawo.
Mukuziviswa kweiyo itsva ARM Mali-G71 GPU zvakaratidzwa kuti mhando dzekutanga dzichashandisa ma processor ane chikamu ichi dzichasvika mukati. 2017, saka vagadziri vari kutoshanda pakuita kwayo. Saka, kufunga kuti Samsung Galaxy S8 inoshandisa iyo inogoneka zvachose. Uye, uku kunogona kuve kusvetuka kwehunhu kana uchitamba uye, hongu, kune iyo Virtual Reality.
