Daniel Hruska Thaum lub caij nplooj zeeg no, Apple tau tshaj tawm qhov tshiab iPhone 5s, feem ntau ntawm fuss revolved nyob ib ncig ntawm irreplaceable ntiv tes sensors Kuaj ID, slow-motion videos, tshiab xim variants thiab 64-ntsis processor A7. Tab sis nrog rau cov tub ntxhais muaj zog dual, lub cev ntawm iPhone 5s zais lwm tus processor, ntau qhov tseeb ntawm M7 coprocessor. Txawm hais tias nws tsis zoo li nws thaum xub thawj siab ib muag, qhov no yog kev hloov pauv me me hauv cov khoom siv txawb.
M7 ua ib feem
Kev hais lus, M7 yog ib lub khoos phis tawj nkaus xwb hu ua LPC18A1. Nws yog raws li NXP LPC1800 ib leeg-chip computer, uas ARM Cortex-M3 processor ntaus. M7 tau tsim los ntawm kev hloov kho cov khoom no raws li Apple cov kev xav tau. M7 rau Apple yog tsim los ntawm NXP Semiconductors.
M7 khiav ntawm qhov zaus ntawm 150 MHz, uas txaus rau nws lub hom phiaj, piv txwv li sau cov ntaub ntawv tawm suab. Ua tsaug rau xws li lub moos qis, nws maj mam ntawm lub roj teeb. Raws li cov kws tsim vaj tsev lawv tus kheej, M7 tsuas yog xav tau 1% ntawm lub zog uas A7 xav tau rau tib txoj haujlwm. Ntxiv nrog rau lub moos qis dua piv rau A7, M7 kuj siv qhov chaw tsawg dua, tsuas yog ib tus nees nkaum.
Qhov M7 ua li cas
M7 co-processor saib xyuas lub gyroscope, accelerometer thiab electromagnetic compass, piv txwv li tag nrho cov ntaub ntawv hais txog kev txav mus los. Nws sau cov ntaub ntawv no hauv keeb kwm yav dhau txhua ob, ib hnub dhau ib hnub. Nws khaws lawv rau xya hnub, thaum twg cov neeg thib peb app tuaj yeem nkag mus rau lawv, thiab tom qab ntawd tshem tawm lawv.
M7 tsis tsuas yog sau cov ntaub ntawv txav, tab sis muaj tseeb txaus kom paub qhov nrawm ntawm cov ntaub ntawv sau. Qhov no txhais tau li cas hauv kev xyaum yog tias M7 paub seb koj tab tom taug kev, khiav lossis tsav tsheb. Nws yog lub peev xwm no, ua ke nrog cov neeg tsim khoom txawj ntse, uas ua rau muaj kev siv zoo tshiab rau kev ua kis las thiab kev tawm dag zog.
M7 txhais li cas rau daim ntawv thov
Ua ntej M7, txhua daim ntawv thov "kev noj qab haus huv" yuav tsum tau siv cov ntaub ntawv los ntawm accelerometer thiab GPS. Nyob rau tib lub sijhawm, koj yuav tsum khiav lub app ua ntej kom nws khiav hauv keeb kwm yav dhau thiab thov thiab sau cov ntaub ntawv tas li. Yog tias koj tsis tau khiav nws, koj yuav tsis paub tias koj tau khiav deb npaum li cas lossis pes tsawg calories koj tau hlawv.
Ua tsaug rau M7, qhov teeb meem ntawm yuav tsum tau tshaj tawm cov haujlwm kaw tseg app raug tshem tawm. Vim tias M7 cov ntaub ntawv txav mus txhua lub sijhawm, txhua lub app uas koj tso cai rau nkag mus rau M7 cov ntaub ntawv tuaj yeem ua tiav nws tam sim ntawd thaum tso tawm thiab qhia koj tias koj tau taug kev ntau npaum li cas hauv ib hnub lossis ntau npaum li cas koj tau ua, txawm tias koj tau mus. 'tsis tau hais kom lub app kaw ib yam dab tsi.
Qhov no tshem tawm qhov yuav tsum tau siv lub cev qoj ib ce xws li Fitbit, Nike FuelBand lossis Jawbone. M7 muaj ib qho txiaj ntsig zoo rau lawv, uas twb tau hais lawm - nws tuaj yeem paub qhov txawv ntawm kev txav mus los (taug kev, khiav, tsav tsheb hauv tsheb). Yav dhau los cov kev tawm dag zog tuaj yeem ua yuam kev xav tias koj tsiv mus, txawm tias koj tsuas yog zaum ntawm lub tsheb ciav hlau. Qhov no ntawm chav kawm ua rau skewed tau.
Dab tsi M7 yuav coj koj
Tam sim no, cov neeg nquag uas xav paub ntau npaum li cas lawv taug kev hauv ib hnub, pes tsawg calories lawv hlawv lossis pes tsawg kauj ruam lawv taug kev yuav zoo siab rau M7. Txij li thaum M7 khiav tsis tu ncua thiab sau cov ntaub ntawv tawm suab yam tsis muaj kev cuam tshuam, cov txiaj ntsig tau raug heev. Ntawd yog, piv txwv tias koj khaws koj iPhone nrog koj ntau li ntau tau.
Qee daim ntawv thov twb tau siv tag nrho lub peev xwm ntawm M7. Kuv yuav npe piv txwv Nyiaj Pov Vaj los yog Txav Mus. Sij hawm dhau mus, feem ntau ntawm cov kev tawm dag zog yuav ntxiv M7 kev txhawb nqa vim lawv yuav tsum, txwv tsis pub cov neeg siv yuav hloov mus rau kev sib tw. Roj teeb txuag thiab tsis siv neeg sau cov ntaub ntawv thiab tshuaj xyuas yog ob qho laj thawj.
Dab tsi M7 coj rau Apple
Apple nyiam qhia txog nws tus kheej chips. Nws pib hauv 2010 thaum nws qhia lub iPhone 4 uas siv los ntawm A4 processor. Apple tas li sim qhia peb tias ua tsaug rau nws cov chips nws tuaj yeem tshem tawm qhov ua tau zoo tshaj plaws nrog kev siv hluav taws xob qis dua li kev sib tw. Nyob rau tib lub sijhawm, cov lus qhia tshwj xeeb ntawm lwm yam khoom siv feem ntau tsis quav ntsej. Puas yog tus neeg siv nruab nrab saib xyuas, piv txwv li, txog qhov loj ntawm lub cim xeeb ua haujlwm? Tsis muaj. Nws yog txaus rau nws kom paub tias lub iPhone muaj zog thiab nyob rau tib lub sij hawm kav ib hnub rau ib tug xwb.
Qhov no cuam tshuam li cas rau M7? Qhov no tsuas yog ib qho kev lees paub tias kev cai software system ua haujlwm zoo ntawm cov khoom siv kho mob, uas pom zoo tshaj plaws hauv cov qauv high-end. Kua nrog M7 khiav tawm ntawm kev sib tw los ntawm ntau lub hlis. Thaum cov neeg siv iPhone 5s muaj peev xwm txaus siab rau M7-enabled apps rau lub lis piam, qhov kev sib tw tsuas yog muab cov coprocessors ntawm Nexus 5 thiab Motorola X. Cov lus nug tseem nyob seb Google puas muab API rau cov neeg tsim khoom lossis seb nws puas yog kev daws teeb meem.
Nyob rau qee lub sijhawm, Samsung yuav tuaj (tsis muaj lub siab xav) nrog Galaxy S V nrog tus txheej txheem tshiab thiab tom qab ntawd tej zaum HTC One Mega. Thiab ntawm no yog qhov teeb meem. Ob tus qauv yuav siv tus txheej txheem sib txawv thiab ob tus neeg tsim khoom yuav zaum ntxiv lawv cov apps qoj. Tab sis tsis muaj lub moj khaum zoo li Core Motion rau iOS, cov neeg tsim khoom yuav raug daig. Qhov no yog qhov uas Google yuav tsum tau los thiab teeb tsa qee txoj cai. Yuav siv sijhawm ntev npaum li cas rau qhov tshwm sim? Lub caij no, kev sib tw tsawg kawg yuav nce tus naj npawb ntawm cov cores, megapixels, nti thiab gigabytes ntawm RAM. Txawm li cas los xij, Apple tseem muaj nws txoj hauv kev xav txog pem hauv ntej ntawm txoj kev
Txoj kev ntawm cov chips tshwj xeeb no yog qhov tsis ntseeg tau zoo heev thiab zoo dua li txoj hauv kev ntawm 4 lossis ntau dua cov tub ntxhais CPUs, tus neeg siv tsis muaj sijhawm los paub nws, feem ntau nws yog hais txog kev ua haujlwm ntawm ib qho tseem ceeb.
Tab sis ... Tau kawg, cov ntawv thov tuaj yeem txheeb xyuas cov ntsiab lus ntawm lub zog uas twb muaj lawm ntawm tus tsav, tab sis lawv yuav tsum siv lawv tus kheej algorithms rau qhov no, qhov zoo ntawm qhov no yog qhov ncaj qha rau HW, yog li nws nrawm dua thiab. kev lag luam ntau dua, ntxiv rau tsis tas yuav tsum khiav daim ntawv thov hauv keeb kwm yav dhau.
Lwm qhov yog tias Motorola X txawm muaj ob tus neeg ua haujlwm sib koom ua ke, ib qho rau sau cov ntaub ntawv los ntawm lub ntsuas ntsuas, lwm qhov rau kev paub hais lus, yog li Apple tej zaum tsis muaj lub taub hau zoo li nws yuav zoo li los ntawm tsab xov xwm.
Ib yam li ntawd, Android 4.4 muaj API tshiab rau kev tshwm sim batching, uas yog qhov pib zoo ib yam (Kuv tsis paub, tab sis cov ntsiab lus tseeb, kom ncaj ncees) - qhov no dua yuav tsum muaj kev txhawb nqa hauv HW - Nexus 5 muaj nws ntawm no, thiab tej zaum lub Moto X nyob ntawd ib yam nkaus, yog tias lawv tsis xav tias nws yog tus tswv.
Kuv ua li cas overlooked Moto X, thiab qhov ntawd yog thaum kuv nyeem nws qhov kev tshuaj xyuas. Kuv tsuas nyeem txog kev paub hais lus nyob ntawd. Nws yog qhov kev tshuaj xyuas tsis zoo lossis kev lag luam tsis zoo los ntawm Google.
Nexus 5 kuj muaj xws li ib tug coprocessor zoo sib xws:

Ua tsaug Dan; Kuv xav tias kuv yuav tau tshawb fawb txog qhov M7 tuaj yeem ua tau zoo rau, thiab kuv xav tias nws yuav nthuav. Tsaug rau cov ntaub ntawv nthuav!
HTC One-> HTC One Max-> HTC One Mega-> HTC One Giga -> Kuv tsis tuaj yeem xav txog lwm yam :DZ los ntawm qhov kev pom no, Kuv zoo siab tias Apple tsuas yog Kua! ;)
Thiab qhov ntawd yog qhov tseeb ... Thaum twg kuv cov phooj ywg pib "taunting" kuv tias kuv lub khw rau 20 txhiab tsuas muaj 8 mpx thiab 1 GB ntawm ram, kuv tsuas yog luag nyav, vim tsis zoo li lawv cov super txhawb HTC lossis Galaxy Cosi, nws tsis tshua muaj tshwm sim rau kuv. tias daim ntawv thov poob lossis qee yam tsis ua haujlwm, thiab kuv cov duab yog kwv yees li 10x zoo dua li lawv lub koob yees duab nrog ob zaug qhov kev daws teeb meem, uas lawv tsuas tuaj yeem ua kom zoo dua, vim tias lawv tseem tso cov duab ntawm lub monitor nrog kev daws teeb meem ntawm 1280 × 960. . :)
Cov lus zoo heev! Qhov ntau ntawm lawv, qhov zoo dua. Kuv txaus siab rau tus sau :). Thaum kuv xub saib nws, kuv xav tias 5S tsuas yog lub xov tooj nrawm dua nrog tus nyeem ntiv tes, tab sis cov "me me" ua qhov txawv. Txawm li cas los xij, hmoov tsis, qhov no tsis hloov qhov tseeb tias 5S tseem yog lub xov tooj astronomically luv nqi. Kuv txaus siab them 40 rau MacBook, nrog rau 10-14 rau iPad, tab sis yuav luag 20 rau lub xov tooj uas tuaj yeem ua tau ntau, tab sis tsis yog tiag tiag. Kuv lub iPhone kawg yog 4S, uas kuv yuav los ntawm Vodafone rov qab los rau 9500CZK nrog rau daim ntawv cog lus rau lub hlis, tab sis txij li thaum ntawd kuv tsis muaj ib qho thiab kuv tsis tau npaj rau, muab cov nqi vwm.
Tom qab 10 km ntawm txoj kev khiav, Runkeeper qhia kuv 6 km luv, yog li kuv tsis tuaj yeem pom qhov kev siv :-( tib qho kev xaiv yog siv GPS ntsuas qhov kev ncua deb ...
Hmm Kuv siv Moves app, ua haujlwm zoo heev. Txawm tias kuv tsis tau caij tsheb kauj vab thiab kuv muaj ib lub tsheb kauj vab uas sau tseg rau ntawd :D Kuv yuav tsum tau nce 100 tus tsiaj :D Tab sis kuv tsis xav hloov tshiab thaum kuv kaw lub app thiab tig nws tom qab ob hnub. Kuv tsis tuaj yeem thauj cov ntaub ntawv. Kuv tam sim no offline. Thiab kuv muaj ib tug iPhone 5s..Tsis paub tias qhov teeb meem yog dab tsi?
