Ibhodi yeCoral Dev
Xa sithetha ngeekhompyuter, wonke umntu ucinga ngeelaptops okanye iidesktops. Asisoloko sithathela ingqalelo i-10- ii-laptops ezincinci okanye, into esithetha ngayo kakhulu kwi-HWLibre, iibhodi ezinje ngeRaspberri Pi okanye iArduino. Ezi bhodi, ezineephakheji ezisisiseko ezingabandakanyi enye into, zisebenza njengengqondo kuyo nayiphi na into, njengeziko lemultimedia, a isantya sejubane okanye ispy cam. Kodwa kuya kuthini ukuba sifuna "ingqondo engaphezulu"? Kubonakala ngathi yile nto uGoogle anayo engqondweni xa kusungulwa ifayile ye- Ibhodi yeCoral Dev.
Ithini ibhodi entsha ukuba le ntengiso ilawulwa yiRaspberry Pi kunye neArduino? Ngaphezulu kunokuba besinokucinga ekuqaleni. Iibhodi zanamhlanje zenzelwe ukuba zisetyenziswe kwizixhobo ezinemisebenzi eqhelekileyo. Phakathi kwale misebenzi kungafuneka sisebenzise inkqubo yokusebenza, ukuba ayisiyonto inzima kakhulu. Iinkqubo zokusebenza, endicinga ukuba zezona zinto zinzima kakhulu ezinokwenziwa ziibhodi ezikhoyo, zinokuba nzima, kodwa aziyonto xa ithelekiswa ne-AI. Ibhodi yeCoral Dev Yenziwe ngobukrelekrele bobugcisa engqondweni, ukuze abaphuhlisi bakwazi ukwenza iiprojekthi zabo kule ndawo.
Iinkcukacha zobuchwephesha beBhodi yeCoral Dev
Kuthatha kuphela ukujonga ukubona ukuba iBhodi yeCoral Dev ayisiyo "iRaspberry kaGoogle." Ngoba? Kuba ifeni eyakhelwe-ngaphakathi icacile ukunqanda ukugqithisa. Ukongeza kweli candelo, eyona inkulu ukuza kuthi ga ngoku, sine:

- Ubukhulu: 88mm x 60mm x 24mm
Isizathu sexabiso laso
Ibhodi yesiseko yeCoral
Ndicinga ukuba ixabiso lifanele icandelo elikhethekileyo, nokuba lifutshane. Okwangoku, ukuba siya eAmazon siyifumana I-Raspberry Pi 3 Model B + ngaphantsi kwe- € 40. Ibhodi yeCoral Dev ayikafumaneki kwezinye iivenkile, kuphela iyafumaneka kwivenkile yakho esemthethweni, kwaye ixabiso layo $ 149.99, malunga ne- € 133 yokutshintsha. Isizathu silula: iBhodi yeCoral Dev ayidlali kwiligi efanayo neRaspberry okanye iArduino. Ukuba sijonga kwi-RAM, ezinye izibuko, njl., Sinokucinga njalo, kodwa ibhodi entsha kaGoogle inayo yonke into eyimfuneko kubaphuhlisi ukuba bayisebenzise kwi-Artificial Intelligence kunye neeprojekthi ze-ML (zokuFunda ngomatshini).
Umahluko phakathi kwento esinokuyenza phakathi kweCoral kunye nezinye iipleyiti kukuba iCoral ijonge kwikamva, ngelixa iipleyiti esaziyo sonke ukuba zikhona ngoku. Kwilixa elizayo kuya kubakho izixhobo ze-IoT (intanethi yezinto) kuzo zonke iimbombo zendlu yethu nangaphandle kwayo kunye nezi izixhobo ziya kufunda imikhwa yethu ukusinceda senze nawuphi na umsebenzi ngokukhawuleza, ngokufanelekileyo nangakumbi. Ngamafutshane, yenza ubomi bube lula ngakumbi.
Ngenkqubo yokusebenza kaMendel, esekwe kwiDebian
Elinye lawona manqaku alungileyo ale bhodi kukuba akukho mfuneko yokuba kuqalwe ekuqaleni ngeeprojekthi. I- "Coral Developer Board" (leyo "yiBhodi yeDev") ibandakanya inkxaso ye- I-TensorFlow Lite, iimodeli ezinokudityaniswa ukuba zisebenze kwiBhodi yeCoral Dev. Ibhodi iza nenkqubo yokusebenza epheleleyo efakiweyo, kwaye le yenye yamandla ayo kum. Inkqubo yokusebenza ibandakanyiwe Mendel, inkqubo esekwe eDebian. Ukuba iDebian ayivakali njengawe, ngokuqinisekileyo Ubuntu buya kuvakala njengawe, enye yeenguqulelo ezidumileyo zeLinux esekwe kwiDebian leyo kwabanye ayaziwa.
Oko kubandakanya inkqubo yokusebenza esekwe kwi-Debian kuthetha ukuba Uyakwazi ukusebenzisa zonke (okanye phantse zonke) izixhobo ezikhoyo zeLinux. Ngapha koko, Ubuntu yinkqubo yokusebenza ethandwa kakhulu phakathi kwabaphuhlisi kwaye yonke into enokwenziwa ngoBuntu inokwenziwa ngoMendel. Njengomsebenzisi we-Linux, ndingaphantse ndiqinisekise ukuba phakathi kweeyantlukwano ezimbalwa abasebenzisi be-Mendel abaza kudibana nazo iya kuba yi-interface yomsebenzisi kwaye apho unqakrazo ngalunye luya kufuneka lwenziwe.
I-Coral Accelerator ye-Coral: ingqondo edityaniswe yi-USB
Isantya seCorce Accelerator
Kwangelo xesha njengeBhodi yeDev, uGoogle ukwazile ukwazisa Isantya seCorce Accelerator. Ndicinga ukuba ixabiso layo lichaza kancinci umahluko phakathi kweBhodi yeCoral Dev kunye neRaspberry Pi okanye iArduino. Inkqubo ye- Isongezelelo se-USB ixabisa i $ 74.99 kwaye ngaphakathi ibaluleke kakhulu kwiBhodi ye-Dev, oko kukuthi, into esinokuyibiza ngokuba yingqondo eya kusivumela ukuba senze i-Artificial Intelligence kunye neeprojekthi zokuFunda ngomatshini. Ukuba sidibanisa phantse i-66 ye- € ukuba i-Raspberry Pi ixabise i-40 yeeRandi, besele sinee-100 zeerandi, malunga ne- € 30 engaphantsi kweendleko zebhodi epheleleyo. Ewe kunjalo, kufuneka siyikhumbule into yokuba nge-30 Euro ngesele sinayo ipleyiti ebekiweyo. Ukusuka kule ndawo yokujonga kunye nokuthathela ingqalelo ukuba isiqinisekiso sinikezwe nguGoogle, ixabiso likwinqanaba lentengiso okanye liphezulu nje.
Injongo yabaphuhlisi
Njengoko igama lisitsho, iBhodi yeCoral Dev kunye ne-USB Accelerator zenziwe kunye nabaphuhlisi engqondweni. Umsebenzisi oqhelekileyo akafuneki ezo ndawo "zobuchopho" ezikuvumela ukuba usebenze iArtificial Intelligence okanye iiprojekthi zokuFunda ngomatshini. Ndiyicacisa le nto kuba akufuneki sithwalwe kukuthenga abathengi kwaye sithenge ipleyiti esiza kuyimosha ukuba into esiyifunayo kukwenza iziko lemultimedia okanye isantya. Ngapha koko, ndaye ndacinga ukuthenga iRaspberri Pi yeziko lam lemultimedia, kodwa ngaphezulu kancinci, ndathenga ibhokisi eseti ephezulu ene-Android TV, endinika yonke into endiyifunayo nokunye okuninzi.
Kwelinye icala, kwaye njengazo zonke iipleyiti zolu hlobo, kufuneka kuthathelwe ingqalelo oko ayibandakanyi nayiphi na ibhokisi ukuyibeka, ke kuyakufuneka sisebenze nebhodi evulekileyo, siyenzele ibhokisi, silinde umntu ukuba athengise izixhobo okanye iseti ebandakanya uhlobo oluthile lwenkxaso, unikezelo lwamandla, njlnjl.
