ICoral Dev Board
Uma sikhuluma ngamakhompyutha, wonke umuntu ucabanga ngama-laptops noma ama-desktops. Asivamisile ukubheka ama-mini-laptops ayi-10 or noma, esikhuluma ngakho kakhulu ku-HWLibre, amabhodi afana neRaspberri Pi noma i-Arduino. Lawa mabhodi, iphakethe lawo eliyisisekelo elingafaki okunye okunye, lisebenza njengobuchopho nganoma yini, njengesikhungo semultimedia, a isivinini noma a ikhamera yokuhlola. Kepha kuthiwani uma sidinga "ubuchopho obuningi"? Kubukeka sengathi yilokhu iGoogle ebikucabanga ngakho lapho yethula i- ICoral Dev Board.
Liyini iphuzu lebhodi elisha uma le makethe ilawulwa yiRaspberry Pi ne-Arduino? Ngaphezu kwalokho ebesingakucabanga ekuqaleni. Amabhodi anamuhla enzelwe ukusetshenziswa kumadivayisi anomsebenzi ojwayelekile. Phakathi kwale misebenzi singaba nohlelo lokusebenza, inqobo nje uma ingeyona enzima kakhulu. Izinhlelo zokusebenza, engicabanga ukuthi ziyinkimbinkimbi kakhulu amabhodi akhona angazenza, zingaba yinkimbinkimbi, kepha azilutho uma ziqhathaniswa ne-AI. Ibhodi LeCoral Dev Yenziwe nge-Artificial Intelligence engqondweni, ukuze onjiniyela bakwazi ukwenza amaphrojekthi abo kulo mkhakha.
Imininingwane ye-Coral Dev Board
Kuthatha ukubheka nje ukubona ukuthi i-Coral Dev Board akuyona "i-Google Raspberry." Kungani? Ngoba fan eyakhelwe ngaphakathi isobala ukugwema ukushisa ngokweqile. Ngaphezu kwalesi sakhi, esikhulu kunazo zonke, sine:
Imodyuli ye-Edge TPU

Isizathu sentengo yayo
I-Coral Baseboard
Ngicabanga ukuthi intengo ifanele isigaba esikhethekile, noma ngabe sifushane. Njengamanje, uma siya e-Amazon sithola ifayela le- I-Raspberry Pi 3 Isibonelo B + ngaphansi kuka- € 40. I-Coral Dev Board ayitholakali kwezinye izitolo okwamanje, kuphela iyatholakala esitolo sakho esisemthethweni, futhi intengo yayo ingu- $ 149.99, cishe u- € 133 ukushintsha. Isizathu silula: Ibhodi ye-Coral Dev ayidlali kuligi efanayo ne-Raspberry noma i-Arduino. Uma sibheka i-RAM, amanye amachweba, njll, singacabanga kanjalo, kepha ibhodi elisha le-Google linakho konke okudingekayo konjiniyela ukuthi bakusebenzise kumaphrojekthi abo we-Artificial Intelligence neML (Machine Learning).
Umehluko phakathi kwalokho esingakwenza phakathi kweCoral namanye amapuleti ukuthi iCoral ibheka ikusasa, kuyilapho amapuleti esazi sonke ukuthi akhona manje. Ngaleso sikhathi esizayo kuzoba nemishini ye-IoT (i-intanethi yezinto) kuwo wonke amagumbi endlu yethu nangaphandle kwayo nalokhu amadivayisi azofunda imikhuba yethu ukusisiza ukuthi senze noma yimuphi umsebenzi ngokushesha, ngempumelelo nangaphezulu Ngamafuphi, yenza impilo ibe ntofontofo.
Ngohlelo lokusebenza lukaMendel, olususelwa kuDebian
Elinye lamaphuzu amahle aleli bhodi ukuthi akudingekile ukuqala amaphrojekthi zisuka. I- "Coral Developer Board" (lelo "Ibhodi Le-Dev") ifaka ukusekelwa kwe- I-TensorFlow Lite, amamodeli angahlanganiswa ukuze asebenze kwiCoral Dev Board. Ibhodi liza nohlelo olugcwele lokusebenza olufakiwe, futhi lokhu kungenye yamandla alo kimi. Uhlelo olusebenzayo olufaka phakathi Mendel, uhlelo olususelwa ku-Debian. Uma iDebian ingazwakali njengawe, ngokuqinisekile Ubuntu izwakala njengawe, enye yezinguqulo ezaziwa kakhulu zeLinux esekwe kuleyo Debian yokuthi kwabanye ayaziwa.
Ukuthi kufaka uhlelo olususelwa ku-Debian kusho ukuthi uzokwazi ukusebenzisa wonke (noma cishe wonke) amathuluzi atholakala ku-Linux. Eqinisweni, Ubuntu wuhlelo olusebenzayo oluthandwa kakhulu phakathi kwabathuthukisi futhi konke okungenziwa ngo-Ubuntu kungenziwa nge-Mendel. Njengomsebenzisi we-Linux, ngingacishe ngiqinisekise ukuthi phakathi kwemehluko embalwa abasebenzisi be-Mendel abazohlangana nayo kuzoba isixhumi esibonakalayo somsebenzisi nalapho ukuchofoza ngakunye kuyodingeka kwenziwe.
ICoral USB Accelerator: ubuchopho obuxhunywe yi-USB
I-Coral USB Accelerator
Ngesikhathi esifanayo neBhodi ye-Dev, iGoogle nayo yethule i- I-Coral USB Accelerator. Ngicabanga ukuthi intengo yayo ichaza kancane umehluko wentengo phakathi kweCoral Dev Board neRaspberry Pi noma i-Arduino. I- I-USB Accelerator kubiza u- $ 74.99 futhi ngaphakathi kunebhodi ebaluleke kunazo zonke ye-Dev Board, okungukuthi, lokho esingakubiza ngokuthi ubuchopho obuzosivumela ukuthi senze amaphrojekthi we-Artificial Intelligence neMishini yokufunda. Uma sifaka cishe ama-euro angama-66 ukuthi i-Raspberry Pi ibaluleke ku- € 40, besizobe sesivele sinama- € 100, cishe ama- € 30 ngaphansi kwezindleko zebhodi eligcwele. Vele, kufanele sikhumbule ukuthi ngalezo € 30 sizobe sesivele sifaka ipuleti. Ngokwalokhu kubuka futhi ucabangela ukuthi isiqinisekiso sinikezwa i-Google, intengo isezingeni lemakethe noma iphakeme nje kancane.
Kuhloselwe onjiniyela
Njengoba igama lisho, iCoral Dev Board kanye ne-USB Accelerator zidalwe kucatshangelwa onjiniyela. Umsebenzisi ojwayelekile akazidingi lezo zingxenye "zobuchopho" ezivumela ukwenza amaphrojekthi we-Artificial Intelligence noma we-Machine Learning. Lokhu ngikuchaza ngoba akumele sithathwe wumthengi futhi sithenge ipuleti esizolichitha uma esikufunayo ukudala isikhungo semultimedia noma i-speedometer. Eqinisweni, nami ngacabanga ukuthenga i-Raspberri Pi ngesikhungo sami semultimedia, kepha ngokuncane, ngathenga ibhokisi lokusetha nge-Android TV, enginika konke engikudingayo nokunye okuningi.
Ngakolunye uhlangothi, futhi njengamanye amapuleti alolu hlobo, kufanele kubhekelwe lokho ayifaki ibhokisi lokuyibeka, ngakho-ke kuzofanele sisebenzisane nebhodi evulekile, siyakhele ibhokisi, silinde umuntu ozothengisa izesekeli noma isethi efaka uhlobo oluthile lokusekelwa, ukunikezwa kwamandla, njll, njengoba kwenza i-Raspberry Pi.
Ucabangani ngeCoral Dev Board kanye nomfowabo i-USB Accelerator?
