Google yatulutsa Mendel Linux 4.0 yogawa kwa ma Coral board

Google представила Kusintha kogawa Sinthani Linux, yogwiritsidwa ntchito pamatabwa Makoralimonga Dev Board и SoM. Dev Board ndi nsanja yopangira ma prototypes a machitidwe a Hardware kutengera Google Edge TPU (Tensor Processing Unit) kuti ifulumizitse ntchito zokhudzana ndi kuphunzira kwamakina ndi ma neural network. SoM (System-on-Module) ndi imodzi mwamayankho okonzeka ogwiritsira ntchito makina okhudzana ndi kuphunzira.

Kugawa kwa Linux Mendel maziko kutengera gawo la phukusi la Debian ndipo limagwirizana kwathunthu ndi nkhokwe za pulojekitiyi (maphukusi osasinthidwa a binary ndi zosintha zochokera kuzinthu zazikulu za Debian zimagwiritsidwa ntchito). Zosinthazo zimagwera pakupanga chithunzi chomwe chimachokera ku makadi a eMMC ndikuphatikiza zigawo zothandizira zigawo za hardware za nsanja ya Coral. Zigawo za korali kufalitsa zololedwa pansi pa Apache 2.0.

MendelLinux 4.0 wakhala kutulutsidwa koyamba kusinthidwa kukhala Debian 10 ("buster"). Msonkhanowu umakongoletsedwa ndi machitidwe ophatikizidwa ndipo ulibe zinthu zosafunika, kuphatikizapo Debian 10 zatsopano zokhudzana ndi chithandizo cha SecureBoot ndi AppArmor. Zatsopano zikuphatikiza chithandizo cha OpenCV ndi OpenCL, kugwiritsa ntchito zokutira kwa Device Tree, komanso zosintha za GStreamer, Python 3.7, Linux kernel 4.14 ndi U-Boot bootloader 2017.03.3.

Zina mwazatsopano, kuthekera kogwiritsa ntchito Coral GPU (Vivante GC7000) yomwe idayikidwa pamatabwa imanenedwa kuti imathandizira kutembenuka kwa ma pixel kuchokera ku mtundu wa YUV kupita ku RGB ndikuchita mpaka mafelemu 130 pamphindikati pa kanema wokhala ndi lingaliro. ya 1080p, yomwe ingakhale yothandiza mukamagwiritsa ntchito matabwa pokonza kanema kuchokera ku makamera , kupanga mtsinje mu mtundu wa YUV. Kuti mugwiritse ntchito kuphunzira pamakina kuti muzitha kutsitsa makanema ndi ma audio pa ntchentche, akufunsidwa kugwiritsa ntchito chimango chotseguka MediaPipe. Mwachitsanzo, pamaziko ake mungathe khazikitsani kachitidwe kozindikira ndi kutsata zinthu kapena nkhope mu kanema kuchokera ku kamera yowunikira.

Makina ophunzirira okonzeka komanso ophunzitsidwa kale opangidwa ndi ma processor a Edge TPU omwe amagwiritsidwa ntchito pama board a Coral akupitilizabe kutumizidwa ku tsamba la polojekiti, koma pang'onopang'ono amasamutsidwa ku kabukhu wamba wa zitsanzo zopezeka poyera TensorFlow Hub. Kuti muchepetse njira zothetsera mayankho anu kutengera ma Coral ndi Mendel Linux board, takonzekera kalozera, kuwonetsa momwe mungasonkhanitsire chosankha mwanzeru kuchokera ku zinthu zakale zomwe zimagawa mipira yamitundu ndi yoyera m'mabasiketi osiyanasiyana pogwiritsa ntchito Raspberry Pi ndi Coral USB Accelerator.
