IRaspberry Pi Foundation yakhipha ibhodi yayo yokuqala yePi Pico microcontroller ngoJanuwari odlule, yabiza u- $ 4 nje kuphela. Ngokuya nge-RP2040 SoC yesisekelo, iPi Pico isivele ithengise amakhophi angama-250.000 kwathi i-750.000 iyalelwe.
Engqungqutheleni yakamuva ye-SmallML Talk, umsunguli wesisekelo se-Raspberry Pi foundation, U-Eben Upton, unikeze umbono ngekusasa lesikhulumi. NginoPi Pico, isisekelo sikhombisile intshisekelo yaso ekuhlakanipheni okufakelwayo Futhi ukuphindwaphindwa okulandelayo kulindeleke ukuthi kulethe ukuthuthuka okukhulu ekufundeni komshini.
Amaslayidi athulwe ngu-Eben Upton kulo mcimbi akhombisa ukuthi iPi Pico ingasebenza njengesakhiwo sokwakha amabhodi akhethekile okufundela umshini (ML).
Eqinisweni, IPi Pico yikhadi elincane futhi elingabizi kakhulu elihlanganisa uhlelo lwe-RP2040 ku-chip (SoC) eyenzelwe isisekelo uqobo.
Le SoC ihlanganisa i-chip-dual-core Arm Cortex-M0 + chip esebenza kuze kufike ku-133 MHz, ene-264 KB yememori yokufinyelela engahleliwe engahleliwe (i-SRAM) ne-2 MB yesitoreji se-onboard flash. Ngosayizi omncane (21 x 51 mm), ikhadi lifaka ne-USB port enezikhonkwane ezingama-26 ze-I / O.
“Ngicabanga ukuthi maningi amathuba okuthi kukhona olunye ucezu lwesilicon njengo [RP2040] ovela kuRaspberry Pi. Ngicabanga ukuthi kunethuba elikhulu lapha: ngenxa yesidingo salo sokusebenza kahle kuma-processor, umhlaba omncane we-ML ududulele ukugxila kwangempela kuma-primitives anele ngokwanele. Into ethokozisayo ngalo mhlaba kithi ukuthi umhlaba omile kakhulu maqondana nokuthi ama-primitives abukeka kanjani, ngakho-ke kukhona intshisekelo yocwaningo okwamanje kulokho okungakhiwa ngendlela yokusetshenziswa okungcono, into mhlawumbe ayinakho ukusebenza kwezibalo ngaphezu komgogodla weprosesa, kepha ayinakho konke ukusika okuzungezile.
Isixhumi se-I / O esikhona kumakhompyutha webhodi eyodwa asikho ebhodini le-microcontroller, okungaba nzima. Esikhundleni salokho, isisekelo sinikela ngamaphayiphu anezinhlaka anemiphetho emangele, sengathi ukugqamisa lapho le microcontroller ingasetshenziswa khona kakhulu.
Ipulatifomu ibuye ithengiswe ngama-reels amayunithi angama-600 ukuthi ahlanganiswe nolayini abazenzakalelayo bomhlangano. Ibhodi le-microcontroller elisha lingahlelwa ngolimi lwe-C. Ikhithi yentuthuko ehlangana neVisual Studio inikezwa ngale njongo.
ICortex M0 + ayinayo iprosesa yenombolo yokuntanta. Lesi sici sisingathwa nge-C language programming SDK. Imbobo ye-MicroPython iyatholakala ekhadini lokuphatha isoftware yolimi lwe-Python. Engqungqutheleni ye-tinyML Talk, izipikha ziqaphele ukuthi amakhadi amaningi anikwe amandla wesistimu ayadingeka ku-chip ye-RP2040. Ngakho-ke izinkampani ezinjenge-Adafruit, iPimoroni, neSparkfun zikhipha i-hardware yazo, eziningi zazo ezinezici ezingatholakali ePi Pico.
Upton uthe kulo mcimbi iqembu langaphakathi le-Application Specific ICs I-Raspberry Pi (ASIC) isebenza ku-iteration elandelayo.
Ukwethulwa kwe- Upton uphakamisa ukuthi iqembu libukeka ligxile kuma-accelerator wokukhanya yezinhlelo zokufunda zomshini we-ultra-low. Ngesikhathi ekhuluma e-Upton, wethule isilayidi esithi "Izikhombisi-ndlela Ezizayo." Isilayidi sikhombisa amabhodi amathathu esizukulwane samanje "I-Pi Silicon", amabili awo avela kubalingani bebhodi, iSparkFun's MicroMod RP2040 kanye ne-Arduino's Nano RP2040 Connect.
Owesithathu uvela kwa-ArduCam, umkhiqizi wamakhamera asuselwa endaweni yesikhulumi se-Raspberry Pi. I-ArduCam okwamanje isebenza ku-ArduCam Pico4ML ehlanganisa ukufunda komshini, ikhamera, imakrofoni nemisebenzi yokubonisa ebhokisini lePico.
Iphuzu lokugcina lisikisela ukuthi iphrojekthi yesikhathi esizayo ingaba yini, engaqhamuka ngesimo sama-accelerator wokukhanya, mhlawumbe ama-accumulations amaningi ama-4 kuya kwangu-8 (ama-MAC) ngomjikelezo wewashi ngalinye. Enkulumweni yakhe, u-Upton uthe "kungenzeka kakhulu ukuthi kunesinye isigaba se-silicon esivela ku-Raspberry Pi."
Ekugcineni, uma unentshisekelo yokwazi okwengeziwe ngale nguqulo entsha, ungaxhumana nemininingwane Kulesi sixhumanisi esilandelayo.
