Coral Dev Board: makwikwi eiyo Raspberry Pi, asi akatarisana neAI

Kana tichitaura nezvemakomputa, munhu wese anofunga malaptop kana desktops. Isu hatiwanzo kufunga nezve 10- mini-malaptop kana, izvo zvatinotaura nezvazvo zvakanyanya paHWLibre, mabhodhi akaita saRaspberri Pi kana Arduino. Aya mabhodhi, ane hombe package haasanganisi chimwe chinhu, anoshanda sehuropi kune chero chinhu, senge multimedia centre, a Speedometer kana a spy kamera. Asi ko kana isu tichida "humwe huropi"? Zvinotaridza sekunge izvi ndizvo zvakafungwa neGoogle pamusoro pekutanga iyo Coral Dev Bhodhi.

Ndeipi poindi yebhodhi nyowani kana uyu musika uchitongwa neRaspberry Pi uye Arduino? Zvakawanda kupfuura zvataigona kufunga nezvazvo pakutanga. Mabhodhi anhasi anoitirwa kushandiswa mumidziyo ine mabasa akajairika. Pakati peaya mabasa isu tinogona kuve neanoshanda system inomhanya, chero bedzi isiri iyo inorema kwazvo. Maitiro ekushanda, ayo andinofunga kuti ndicho chinhu chakaomesesa zviripo mabhodhi aripo, anogona kunge akaomarara, asi iwo hapana kana achienzaniswa neAI. Iyo Coral Dev Bhodhi Yakave yakagadzirwa neArtificial Intelligence mupfungwa, kuitira kuti vagadziri vakwanise kuita zvirongwa zvavo mundima iyi.

Coral Dev Board technical technical tsananguro

Zvinongotora kutarisa kuti uone kuti Coral Dev Board haisi "Google Raspberry." Sei? Nekuti fan yakavakirwa iri pachena kudzivirira kupisa zvakanyanya. Pamusoro pechinhu ichi, chikuru nekure, isu tine:

Chikonzero chemutengo wayo

Ini ndinofunga mutengo unofanirwa chikamu chakakosha, kunyangwe kana chiri chipfupi. Parizvino, kana tichienda kuAmazon tinowana iyo Raspberry Pi 3 Mhando B + pasi pe € 40. Iyo Coral Dev Board haisati yawanikwa mune zvimwe zvitoro, zvinongova chete inowanikwa muchitoro chako chepamutemouye mutengo wayo i $ 149.99, inenge € 133 yekuchinja. Icho chikonzero chiri nyore: iyo Coral Dev Board haitambi mune imwechete ligi seRaspberry kana Arduino. Kana isu tikatarisa pa RAM, mamwe madoko, nezvimwe, tinogona kufunga kudaro, asi bhodhi idzva reGoogle rine zvese zvinodiwa kune vanogadzira kuti vazvishandise pamabasa avo eArtificial Intelligence neML (Machine Kudzidza).

Musiyano uripo pakati pezvatinogona kuita pakati peCoral nemamwe mahwendefa ndewekuti Coral inotarisa kune ramangwana, nepo mahwendefa ayo isu tese tinoziva aripo. Mune iro ramangwana pachave neIoT zvishandiso (internet yezvinhu) mumakona ese eimba yedu uye kunze kwayo uye izvi zvishandiso zvinodzidza maitiro edu kutibatsira kuti tiite chero basa nekukurumidza, rinoshanda zvakanyanya uye nyore. Muchidimbu, ita kuti hupenyu huve nyore.

Ndiine Mendel inoshanda sisitimu, yakavakirwa paDebian

Chimwe chezvakanaka zvebhodhi iri ndechekuti hazvidi kuti utange mapurojekiti kubva pakutanga. Iyo "Coral Developer Board" (ndiyo "Dev Board") inosanganisira rutsigiro rwe TensorFlow Lite, mhando dzinogona kuverengerwa kumhanya paCoral Dev Board. Iyo bhodhi inouya iine yakazara inoshanda sisitimu yakaiswa, uye iyi ndeimwe yemasimba ayo kwandiri. Iyo inoshanda sisitimu yarinosanganisira is Mendel, Debian-yakavakirwa sisitimu yekushandisa. Kana Debian isinganzwike senge iwe, zvirokwazvo Ubuntu inonzwika senge iwe, imwe yemhando dzinozivikanwa dzeLinux iyo yakavakirwa pane iyo Debian iyo kune vamwe isingazivikanwe.

Izvo zvinosanganisira iyo Debian-based operating system zvinoreva kuti iwe unozogona kushandisa ese (kana angangoita ese) maturusi anowanikwa kuLinux. Muchokwadi, Ubuntu inonyanyozivikanwa inoshanda sisitimu pakati pevagadziri uye zvese zvinogona kuitwa neUbuntu zvinogona kuitwa neMendel. Semushandisi weLinux, ini ndinogona kuvimbisa kuti pakati pemisiyano mishoma ichasangana nevashandisi veMendel ichave mushandisi interface uye uko kudzvanya kwega kwega kuchafanirwa kuitwa.

Coral USB Accelerator: huropi hwakabatana ne USB

Panguva imwechete seDev Board, Google yatangawo iyo Coral USB Accelerator. Ini ndinofunga mutengo wayo unotsanangura zvishoma musiyano mumutengo pakati peCoral Dev Board neRaspberry Pi kana Arduino. Iyo usb accelerator inokosha $ 74.99 uye mukati mayo mune yakakosha yeDev Board, ndiko kuti, izvo zvatingati uropi izvo zvichatibvumidza isu kugadzira Artificial Intelligence uye Machine Kudzidza mapurojekiti. Kana kune iyo € 66 isu tichiwedzera iyo ingangoita makumi mana € iyo iyo Raspberry Pi yakakosha, isu tanga tatova neinenge € 40, ingangoita € 100 isingasviki pamutengo webhodhi izere. Ehezve, isu tinofanirwa kuziva kuti neaya maeuro e30 isu tanga tatova nendiro yakaiswa. Kubva panguva ino yekutarisa uye uchifunga nezvekuti iyo vimbiso inopihwa neGoogle, mutengo uri padanho remusika kana kungokwirira padiki.

Inotarisirwa kune vanogadzira

Sezvinoreva zita iri, iyo Coral Dev Board uye iyo USB Accelerator zvakasikwa nevagadziri mupfungwa. Mushandisi chaiye haadi izvo zvikamu zve "huropi" zvinobvumidza kuita Artificial Intelligence kana Machine Kudzidza mapurojekiti. Ini ndinotsanangura izvi nekuti hatifanire kutorwa nekutenga zvinhu uye kutenga ndiro yatinozotambisa kana izvo zvatiri kuda kugadzira nzvimbo yemultimedia kana chinomhanyisa. Muchokwadi, ini pachangu ndakafunga kutenga Raspberri Pi yeyangu multimedia centre, asi kune zvishoma zvishoma, ndakatenga set-yepamusoro bhokisi ine Android TV, iyo inondipa zvese zvandinoda uye zvimwe zvakawanda.

Kune rimwe divi, uye sekune mamwe mahwendefa erudzi urwu, zvinofanirwa kutariswa izvo haina kusanganisira chero bhokisi rekuisa, saka isu tichafanirwa kushanda nebhodhi rakasununguka, kugadzira bhokisi kwariri, kumirira mumwe munhu kutengesa zvishongedzo kana seti iyo inosanganisira imwe mhando yerutsigiro, magetsi, nezvimwe, sezvinoita Raspberry Pi.

Iwe unofungei nezve iyo Coral Dev Board uye hama yayo iyo USB Accelerator?
