Daniel Hruska Ngenkathi lokhu kuwa, i-Apple yethula entsha iPhone 5s,umsindo omkhulu wawuzungeza engabuyiseleki izinzwa zeminwe I-ID yokuthinta, amavidiyo ahamba kancane, okuhlukile kwemibala emisha kanye 64-bit iprosesa A7. Kodwa kanye ne-double core enamandla, umzimba we-iPhone 5s ufihla enye iphrosesa, ngokuqondile i-coprocessor ye-M7. Nakuba kungabonakali ngathi ekuqaleni, lokhu kuwuguquko oluncane kumadivayisi eselula.
M7 njengengxenye
Uma sikhuluma ngobuchwepheshe, i-M7 iyikhompyutha ene-single-chip ebizwa nge-LPC18A1. Isekelwe kukhompyutha ye-NXP LPC1800 ye-single-chip, lapho i-ARM Cortex-M3 processor ishaya khona. I-M7 yadalwa ngokulungisa lezi zingxenye ngokwezidingo ze-Apple. I-M7 ye-Apple yakhiwe ngabakwa-NXP Semiconductors.
I-M7 isebenzisa imvamisa ye-150 MHz, eyanele ngezinjongo zayo, okungukuthi ukuqoqa idatha yokunyakaza. Ngenxa yezinga eliphansi lewashi, lithambile ebhethrini. Ngokusho kwabakhi bezakhiwo, i-M7 idinga kuphela u-1% wamandla i-A7 ezowadinga ukuze isebenze. Ngaphezu kwejubane lewashi eliphansi uma liqhathaniswa ne-A7, i-M7 iphinde ithathe indawo encane, eyodwa kuphela yamashumi amabili.
Okwenziwa yi-M7
I-co-processor ye-M7 iqapha i-gyroscope, i-accelerometer nekhampasi kagesi, okungukuthi yonke idatha ehlobene nokunyakaza. Irekhoda le datha ngemuva njalo ngesekhondi, usuku nosuku. Iwagcina izinsuku eziyisikhombisa, lapho noma yiluphi uhlelo lokusebenza lwenkampani yangaphandle engakwazi ukuwafinyelela, bese ewasusa.
I-M7 ayigcini nje ngokurekhoda idatha yokunyakaza, kodwa inembe ngokwanele ukuhlukanisa isivinini phakathi kwedatha eqoqiwe. Lokhu kusho ukuthini uma sekwenziwa ukuthi i-M7 iyakwazi ukuthi uhamba ngezinyawo, ugijima noma uhamba ngemoto. Yileli khono, elihlanganiswe nonjiniyela abanamakhono, elidala izinhlelo zokusebenza ezintsha ezinhle zemidlalo nokuqina.
Kusho ukuthini u-M7 ezicelweni
Ngaphambi kwe-M7, zonke izinhlelo zokusebenza "ezinempilo" kwakudingeka zisebenzise ulwazi oluvela ku-accelerometer ne-GPS. Ngesikhathi esifanayo, bekufanele usebenzise uhlelo lokusebenza kuqala ukuze lusebenze ngemuva futhi ucele njalo futhi urekhode idatha. Uma ungazange uyisebenzise, cishe ngeke wazi ukuthi ugijime ibanga elingakanani noma mangaki amakholori owashisile.
Ngenxa ye-M7, inkinga yokuthi uqalise uhlelo lokusebenza lokuqopha umsebenzi isusiwe. Ngenxa yokuthi ukunyakaza kwamarekhodi e-M7 ngaso sonke isikhathi, noma yiluphi uhlelo lokusebenza oluvumelayo ukuthi lufinyelele idatha ye-M7 lungalucubungula ngokushesha lapho yethulwa futhi likubonise ukuthi mangaki amakhilomitha owahambe ngosuku noma zingaki izinyathelo ozithathile, ngisho noma Angitshelanga uhlelo lokusebenza ukuthi liqophe noma yini.
Lokhu kuqeda isidingo sokusebenzisa amabhendi okuqina afana ne-Fitbit, i-Nike FuelBand noma i-Jawbone. I-M7 inenzuzo eyodwa enkulu phezu kwabo, osekushiwo kakade - ingakwazi ukuhlukanisa uhlobo lokunyakaza (ukuhamba, ukugijima, ukushayela imoto). Izinhlelo zokusebenza zokufaneleka zangaphambilini zingacabanga ngephutha ukuthi uyanyakaza, noma ngabe ubuhlezi nje unganyakazi ku-tram. Lokhu kuholele emiphumeleni etshekile.
Uzokulethela ini uM7
Njengamanje, abantu abakhuthele abanentshisekelo yokuthi mangaki amakhilomitha abahamba ngawo ngosuku, mangaki amakholori abawashisile noma bangaki izinyathelo abazihambile bazojabula nge-M7. Njengoba i-M7 isebenza ngokuqhubekayo futhi iqoqa idatha yokunyakaza ngaphandle kokuphazamiseka, imiphumela inembe kakhulu. Okusho ukuthi, ucabanga ukuthi ugcina i-iPhone yakho nawe ngangokunokwenzeka.
Ezinye izinhlelo zokusebenza sezivele zisebenzisa ngokugcwele amandla e-M7. Ngingasho isibonelo I-RunKeeper noma Uyanyakaza. Ngokuhamba kwesikhathi, iningi lezinhlelo zokusebenza zokufaneleka zizongeza ukwesekwa kwe-M7 ngoba kufanele, ngaphandle kwalokho abasebenzisi bazoshintshela emqhudelwaneni. Ukonga ibhethri nokuqoqwa kwedatha okuzenzakalelayo nokuhlaziywa yizizathu ezimbili ezinamandla.
Okulethwe yi-M7 ku-Apple
I-Apple ithanda ukugqamisa ama-chips ayo. Iqale ngo-2010 lapho yethula i-iPhone 4 enikwa amandla yi-A4 processor. I-Apple ihlale izama ukusitshela ukuthi ngenxa yama-chips ayo ingakhipha ukusebenza okuphezulu ngokusetshenziswa kwamandla okuphansi kunomncintiswano. Ngesikhathi esifanayo, ukucaciswa kwezinye i-hardware kuvame ukunganakwa. Ingabe isilinganiso somsebenzisi siyakhathalela, ngokwesibonelo, mayelana nosayizi wememori yokusebenza? Cha. Kwanele ukuba azi ukuthi i-iPhone inamandla futhi ngesikhathi esifanayo ihlala usuku lonke ngokukhokhiswa okukodwa.
Lokhu kuhlobana kanjani ne-M7? Lokhu kumane kuyisiqinisekiso sokuthi uhlelo lwesofthiwe yangokwezifiso lusebenza kahle ku-hardware yangokwezifiso, ebonakala kangcono kumamodeli asezingeni eliphezulu. I-Apple ene-M7 yawubalekela umncintiswano ngezinyanga eziningi. Nakuba abasebenzisi be-iPhone 5s bekwazile ukujabulela ngokugcwele izinhlelo zokusebenza ezinikwe amandla i-M7 amasonto amaningi, umncintiswano unikeza kuphela ama-coprocessors ku-Nexus 5 ne-Motorola X. Umbuzo usasele ukuthi ingabe i-Google inikeza i-API kubathuthukisi noma ingabe isixazululo sobunikazi.
Ngokuhamba kwesikhathi, i-Samsung izofika (ayikho i-pun ehlosiwe) ne-Galaxy S V nge-co-processor entsha bese mhlawumbe i-HTC One Mega. Nansi inkinga. Womabili amamodeli azosebenzisa i-co-processor ehlukile futhi bobabili abakhiqizi bazongeza izinhlelo zabo zokusebenza zokufaneleka. Kodwa ngaphandle kohlaka olufanele njenge-Core Motion ye-iOS, abathuthukisi bazovaleleka. Yilapho i-Google kufanele ingene futhi isethe imithetho ethile. Kuzothatha isikhathi esingakanani ukuthi lokho kwenzeke? Khonamanjalo, umncintiswano uzokwandisa okungenani inani lama-cores, ama-megapixel, amayintshi namagigabhayithi e-RAM. Kodwa-ke, i-Apple iyaqhubeka nokuba nendlela yayo phambili-ukucabanga ngisendleleni
Le ndlela yama-chips akhethekile akungabazeki ukuthi yinhle kakhulu futhi ingcono kakhulu kunendlela yama-CPU angu-4 noma ngaphezulu, umsebenzisi akanalo ithuba lokuyazi, ikakhulukazi imayelana nokusebenza kumongo owodwa noma kunjalo.
Kodwa... Yiqiniso, izinhlelo zokusebenza zikwazi ukubona umongo wokunyakaza kakade ku-drive, kodwa kwakudingeka basebenzise ama-algorithms abo kulokhu, inzuzo yalokhu ukuthi iqondile ku-HW, ngakho-ke iyashesha futhi ukonga okwengeziwe, futhi asikho isidingo sokusebenzisa uhlelo ngemuva.
Enye into ukuthi i-Motorola X iqukethe ngisho nama-co-processors amabili, enye eyokuqopha idatha kusuka ku-accelerometer, enye eyokuqaphela inkulumo, ngakho-ke i-Apple cishe ayinaso isiqalo esinjalo njengoba kungase kubonakale kusihloko.
Ngokufanayo, i-Android 4.4 ine-API entsha yokuhlanganiswa komcimbi, efanayo ngokuyisisekelo (angazi, kodwa imininingwane eqondile, ukukhuluma iqiniso) - lokhu kuphinde kudinga ukusekelwa ku-HW - i-Nexus 5 inayo lapha, futhi mhlawumbe i-Moto X lapho futhi, uma bengacabanganga njengokuphathelene nayo.
Ngandlela thize ngiyishaye indiva i-Moto X, futhi yilapho-ke ngafunda isibuyekezo sayo. Ngifunde kuphela ngokuqashelwa kwenkulumo lapho. Kungaba isibuyekezo esibi noma ukumaketha okubi kwe-Google.
I-Nexus 5 ihlanganisa ne-coprocessor efanayo:

Ngiyabonga Dan; Ngacabanga ukuthi kuzomele ngicwaninge ukuthi i-M7 ingasiza ngani, futhi ngasola ukuthi ingase ibe mnandi. Siyabonga ngolwazi oluthokozisayo!
I-HTC One-> I-HTC One Max-> I-HTC One Mega- > I-HTC One Giga -> Akukho okunye engikucabangayo :DZ ngokwalo mbono, ngiyajabula ukuthi i-Apple imane nje i-Apple! ;)
Yilokho kanye... Noma nini lapho engifunda nabo beqala "ukungigcona" ngokuthi isitolo sami sezinkulungwane ezingama-20 sine-8 mpx kanye ne-1 GB yenqama, ngivele ngimamatheke, ngoba ngokungafani ne-HTC yabo ethuthukisiwe noma i-Galaxy Cosi, akuvamile ukuthi kwenzeke kimi. ukuthi uhlelo lokusebenza luphahlazekile noma okuthile akusebenzanga, futhi izithombe zami zisezingeni elingcono le-10x kunamakhamera abo anesixazululo esiphindwe kabili, abangakwazi ukushaya indlwabu kuphela, ngoba zisabonisa izithombe kumonitha ngesinqumo se-1280 × 960 . :)
Isihloko esihle kakhulu! Okuningi kwabo, kungcono. Ngibonga kakhulu umbhali :). Lapho ngiqala ukuyibuka, ngacabanga ukuthi i-5S kwakumane kuyifoni esheshayo enesifundi sezigxivizo zeminwe, kodwa "izinto ezincane" ezinjalo zenza umehluko. Nokho, ngeshwa, lokhu akulishintshi iqiniso lokuthi i-5S iseyifoni enenani lezinkanyezi. Ngizimisele ukukhokha i-40 ye-MacBook, kanye ne-10-14 ye-iPad, kodwa cishe i-20 ngefoni engenza okuningi, kodwa hhayi ngempela. I-iPhone yami yokugcina kwakuyi-4S, engayithenga kwaVodafone ngaleso sikhathi nge-9500CZK ngenkontileka yezinyanga eziyisithupha, kodwa kusukela lapho angizange ngibe nayo futhi angihleli ngisho nokuhlela, uma kubhekwa amanani ahlanya.
Ngemva kwamakhilomitha angu-10 omgwaqo ogijimayo, u-Runkeeper ungibonisa ubude obungu-6 km, ngakho-ke angikwazi ukubona ukusetshenziswa okungokoqobo :-( ukuphela kwenketho ukusebenzisa i-GPS ukukala ibanga elihanjiwe...
Hmm ngisebenzisa uhlelo lokusebenza lwe-Moves, lusebenza kahle. Noma ngingazange ngigibele ibhayisikili futhi nginohambo lwebhayisikili olurekhodiwe lapho :D Kufanele ngabe nginyathele izilwane eziyi-100 :D Kodwa angifuni ukubuyekeza lapho ngicisha uhlelo lokusebenza futhi ngilivula ngemva kwezinsuku ezimbili. Angikwazi ukulayisha noma iyiphi idatha. Okwamanje angixhumekile ku-inthanethi. Futhi ngine-iPhone 5s..Angazi ukuthi inkinga ikuphi?
