Qualcomm Adreno 305: izici, ukusebenza, ukubuyekezwa

Uyini Qualcomm Adreno 305, bambalwa bayazi. Futhi ngisho nalabo abe inkomba abanye ukuthi lokhu into, ingabe ngaso sonke isikhathi ukuqonda ukuthi yini kwaba ngoba. Kusukela ngesikhathi ezimpilweni zethu beqhumuka amafoni smart, kwadingeka ukuba asheshe abheke izindlela ukuthuthukisa uhlelo encishisiwe. Ngakho kwakukhona zonke izilimi zeselula ihluzo encane accelerators.

Kuyini lokhu?

Ngakho, a ihluzo processor, engesiyo kuphela PC, kodwa futhi 'wahlala phansi "Amadivayisi zethu mobile abhekana nezinselele wesimanje. Bobani ezivamile:

• PowerVR;
• mali;
• Adreno;
• GeForce ULP.

Lona izinkampani adumile kakade kungase kutholakale ukuzinza kanye nokusebenza yonkana Smartphones kanye amaphilisi. Ngaphambi kokucabangela le Adreno 305, kubalulekile ukuqonda ukuthi yini imingcele zinezikhathi izilimi ezifana.

amapharamitha

Ngakho, ukuqonda izinto esibhekene nazo ihluzo namafutha, futhi ukusho okuthile mayelana nokusebenza kwakhe, udinga ukubheka ezintathu ongakhetha:

• Isibalo onxantathu ngomzuzwana.
• Inombolo yama-pixels ngomzuzwana.
• Isibalo elintantayo iphuzu imisebenzi.

Yiqiniso, ukuthi lonke ulwazi kungenziwa ihlaziye kuphela ngochwepheshe. Umsebenzisi isilinganiso uzothi ukuthi izibalo kancane kulezi nemingcele. Ngakho ake uthole ilungelo ngqo sethu mobile Adreno 305.

Qualcomm

Le nkampani iye yasungula ezingaphezu kweyodwa processor ephathekayo. Ngokwesibonelo, Smartphones eziningi kungaba ukuziqhayisa kokuba omunye Snapdragon umndeni imifanekiso. Umugqa yakhelwe Smartphones kanye amaphilisi, it is ukusebenza izakhiwo ARM, nokuxhumana amamojuli. Kuyinto lezi izinhlelo mobile ku esitolo chip a chipset, lapho libhekisela hero ukubuyekeza kwethu.

Ngokuvamile, i-Snapdragon uvezwa ezimbili chungechunge, eyokuqala wathola izinkomba S1 / S2 / S3 / S4, kanti eyesibili - 2xx / 4xx / 6xx / 8xx. Kwakuwusuku uchungechunge yesibili Adreno 305. Kuyinto "ocashe" emndenini Snapdragon 400 futhi seyenziwe inqwaba kokushintshwa.

Snapdragon 400

Ngokuvamile, labo abanomkhuba ukuzwisisa model of the processor, chipset, umongo, izinkundla kanye nezinye izinto, ngeke ngokushesha ukuthi iqhinga ezingcolile. Lo mndeni umelwe hhayi imodeli owodwa. Kukhona izinguqulo eziningana nge architectures ezahlukene, cores kanye amaza. Kodwa jikelele, yilowo nalowo kubo kuyinto graphic-nucleus 305-th. Kuyinto zonke, ngakho-ke, uhlolo lokubuka ihlale ifana - 1280x800.

eseyintsha

Imodeli sokuqala "adrenergic" 305 wathola inombolo 8225. Le chipset senziwe 28 nm inqubo nobuchwepheshe ongaphakeme amandla nobuchwepheshe. Processor baba Cortex-A7 ku cores ezine nge imvamisa 1200MHz. Ihluzo namafutha isekela uhla uxhumano olungenantambo: EDGE, i-Bluetooth, i-Wi-Fi, i-GSM, HSPA + ne-GPRS. Lolu khetho bazinza onobuhle eziningi kudivayisi, phakathi okuyinto - Samsung Galaxy S5, le S3 kanye Tab 4, Sony Xperia M2, kanye Microsoft le Lumia 640 XL.

Ukuguqulwa elandelayo cishe zilethe ushintsho ku izici ukushintsha Adreno kuphela 305. CPU imvamisa kusuka 1.2 GHz ukuba 1.4 GHz, kanye namafutha waya Samsung Galaxy S3 SS.

izinguquko

Le nguqulo wesithathu chipset wayaziwa ngekwata yesine ka-2013. Yingaleso sikhathi-ke waqala ekukhiqizweni. amadivaysi kuloluhla abane Nokia Lumia onobuhle chipset futhi zaqala ukusetshenziswa ku izinhlobo of Smartphones Huawei, HTC futhi Acer. Uphiko lobuchwepheshe washintsha futhi kancane. imvamisa Kwabuya 1.2 GHz, kanye nohlu ebuyekeziwe amanethiwekhi wireless esisekelayo: i-DC-HSPA + ne-LTE. Ubuchwepheshe inkumbulo futhi icutshungulwe ngesikhathi LPDDR2 LPDDR3.

Yesikhulumi entsha

Ukuguqulwa elandelayo chipset sezishiye izinguquko ezinqala. Ngakho, isikwele Cortex-A7 esikhundleni ezimbili Krait 200 elinendawo imvamisa 1.2-1.4 GHz. Kukhona idatha ivolumu yokuqala ezingeni isilondolozi 32 KB, kwesibili - 1 MB. Thuthukisa ubuchwepheshe inkumbulo. Kule minyaka emine izinguqulo processor izinguquko Krait 300 futhi isebenza imvamisa ka 1700 MHz. Kulokhu, isikhathi ngasinye ohlwini lamadivayisi ezisebenza chipset, kukhuphuke ngo 3-5 onobuhle.

ukuqhathanisa

Qhathanisa Adreno 305 Adreno 225 - okuvame kakhulu. Lokhu kungenxa yokuthi inguqulo endala kuliragelo lomncane. Eqinisweni, imodeli 305-th - lokhu kuvuselelwa 225th. Wayeqale uvele Snapdragon S4 Pro, kodwa impumelelo enkulu ufinyelelwe ngezindlela umndeni Snapdragon 400. I eseyintsha umehluko itholakala yesimanjemanje yayo. Isekela inombolo enkulu ubuchwepheshe obusha, kulula ukubhekana ne-API, Direct3D 9.3, OpenGL ES 3.0 CL 1.2.

ukuhlolwa

Ukusebenza Adreno 305 kungenziwa kuphela eliqinisekisiwe yimiphumela yokuhlolwa. Yiqiniso, okuningi kuncike kulokho yesikhulumi ibekwe chipset futhi processor okusebenza ngayo ndawonye. Core iwashi imvamisa ifinyelela 450 MHz. flops sepharamitha luphakathi 0.02 futhi kubonisa GPU ukucutshungulwa amandla processor.

0.8 GPixel / s - kuyinto ngesivinini pixels. Lokhu ipharamitha inquma inani Amaphikseli ukuthi ayaboniswa ngomzuzwana. Njengoba kushiwo ngaphambili, imodeli isekela 9.3 nguqulo ye iDirectX, okuyinto kakhulu ngcono ihluzo in imidlalo. Inguqulo ka OpenCL 1.1 - ubuchwepheshe evumela ezinye isofthiwe ukusebenzisa ihluzo namafutha ngezinjongo okungezona sokuqhafaza.

TechProcess ikhenela - 28 NM. Kuqhathaniswa inguqulo yangaphambi zanamuhla is a sibalo esikhulu, kodwa ngo-2013 kwaba wamavukelambuso chipset Ubukhulu.

Izici

Adreno 305 - lena isiqophi processor okuhle, kwaduma 2013. Yingaleso sikhathi lapho kumadivayisi eselula babé ngokushesha ifakwe kule modeli. Wazamukela elinobunye shader izakhiwo. Ngokwesilinganiso imvamisa isiqophi ifinyelela 266 MHz, kodwa empeleni ayaziwa kakade uvusa 450 MHz.

Chipset has a core olulodwa. Ukusetshenziswa kwememori sifinyelela 256 MB. Ngaphakathi ezimbili shader ukucutshungulwa Amaphikseli, omunye geometry processor vertex shaders. Ukusebenza ifinyelela izigidi ezingu-98 onxantathu ngomzuzwana kanye 2.5 billion Amaphikseli esikhathini esifanayo.

Adreno 305 angase aqhube tessellation hardware usebenza nge isikrini esigcwele anti-aliasing isithombe, uhlukanisa yesehlakalo ngakuthathu ku tile, ukukhanyisa kudala hardware isebenza nge-alpha Blanding futhi wathola Z sesikhashana ne-24-bit. Manje angaphezu kuka-50 amafoni smart kanye amaphilisi nge umsebenzi kweshumi nalezi ihluzo namafutha. Iningi amagajethi out of umkhiqizo.

Izibuyekezo

Qualcomm ubelokhu esebenza isikhathi eside nge-GPU Adreno. Izinguqulo zokuqala yaqala ukubonakala ngo-2009 futhi kakade phezu emakethe kanye nabasebenzisi ukunakwa. Manje kukhona izilimi eziyisikhombisa nale ihluzo namafutha. Ngokuvamile, abazi ihluke nomunye. Ngezinye izikhathi vibration lubonakale amaza.

Kusekhona abantu abanayo amafoni smart nge Adreno 305. Izibuyekezo wokugaya isiqophi izinto eziningi ezincane. Sibangelwa yokuthi kuba yingxenye ebalulekile idivayisi yeselula, ngakho-ke uthola Izibuyekezo smartphone, kunokuba izingxenye zalo ngabanye.

Kuyaziwa ukuthi imodeli 2013, okuyinto wathola chipset libhekisela sokwenyusa amanani ingxenye eyaziwa, futhi yabonisa ukusebenza ezinzile, elalingelona ligqame into ekhethekile. Uhlelo nale core wasebenza kahle, sibonga amandla amasu Lean alondoloze ukuzimela idivayisi isikhathi eside.

Ububi oyinhloko ukuthenga leli thuluzi kubhekwa ukuthi umsebenzisi angakwazi sinake Snapdragon 400 atholakala ezibekiweko Inthanethi, ibheka konke nokuwenza. Kodwa eqinisweni kwathi chipset Kuthi buthaka kwezinye izimo ethubeni lokuba ukwehluleka test. Lezi zinkinga zazibangelwa yokuthi a emfushane Snapdragon 400 ngokuvamile kungasho ezimbalwa ezenezelwe, okuyinto, nakuba kwaba Adreno 305, nezinye izinkomba ungase nemikhuba yazo ihluke kakhulu.

Sekukonke, ihluzo kwakukuhle. Wayengakwazi ukukhulelwa wadonsa kwamathoyizi amahle, kodwa izilungiselelo ongaphakeme sibhekane ngokuphumelelayo cishe wonke amaphrojekthi we "Play Store". I ethile eyinhloko ihluzo futhi zonke izilimi kusukela Qualcomm kubhekwe okweqile namuhla. Ngakho manje, abakhiqizi idivayisi eziningi mobile senqabe imikhiqizo wale nkampani futhi makudle Mali.
