I-Raspberry Pi Foundation yasungula ibhodi yayo yokuqala ye-Pi Pico microcontroller ngoJanuwari ophelileyo, oxabisa i-$ 4. Ngokusekelwe kwisiseko se-RP2040 SoC, i-Pi Pico sele ithengise iikopi ze-250.000 kwaye i-750.000 iyaliwe.
Kwinkomfa yamva nje encinci yeNtetho yeML, umseki weRaspberry Pi isiseko, Eben Upton, ubonelele ngekamva leqonga. Ndikunye noPi Pico, isiseko sibonise umdla waso kubukrelekrele bokwenziwa kwaye uphindaphindo lwexesha elizayo kulindeleke ukuba luzise uphuculo olubalulekileyo lokufunda koomatshini.
Izilayidi ezinikezelwe ngu-Eben Upton kumsitho zibonisa ukuba uPi Pico unokusebenza njengebhloko yokwakha ukuyila iidashbhodi ezikhethekileyo zokufunda koomatshini (ML).
Enyanisweni, I-Pi Pico yibhodi encinci, engabizi kakhulu edibanisa inkqubo ye-RP2040 kwitshiphu (SoC) eyilwe sisiseko ngokwaso.
Le SoC idibanisa i-chip ye-Arm Cortex-M0+ ene-dual-core esebenza ukuya kuthi ga kwi-133 MHz, kunye ne-264 KB yememori yokufikelela okungahleliweyo (SRAM) kunye ne-2 MB ye-flash yokugcina. Incinci ngobukhulu (21 x 51 mm), ikhadi likwabandakanya i-port ye-USB enezikhonkwane ezingama-26 ze-I / O.
Ndicinga ukuba kunokwenzeka ukuba kukho enye intwana yesilicon efana neRaspberry Pi's [RP2040]. Ndicinga ukuba kukho ithuba elikhulu apha: ngenxa yesidingo sayo sokusebenza ngokufanelekileyo kwiiprosesa, umhlaba omncinci weML uqhube ugxininiso lokwenyani kwizinto zokuqala ezaneleyo. Into enika umdla ngeli hlabathi kuthi kukuba lilizwe elime kakhulu ngokwendlela imbonakalo yamandulo, ke kukho umdla omncinci wophando ngoku kwinto enokwakhiwa ngendlela yokuphunyezwa okungcono, into ekusenokwenzeka ukuba inakho. akukho ntsebenzo ye-arithmetic ngaphezu kwesiseko seprosesa, kodwa ayinayo yonke i-scaffolding ejikeleze kuyo. "
Isidibanisi se-I/O esikhoyo kwiikhomputha zebhodi enye asikho kwibhodi ye-microcontroller, enokuba yingxaki. Endaweni yoko, isiseko sibonelela ngeepads ezinemingxuma ezinemiphetho engaqhelekanga, ngokungathi kukuqaqambisa apho le microcontroller ingasetyenziswa kakhulu.
Iqonga likwathengiswa ngeereli zeeyunithi ze-600 zokudibanisa kwimigca yendibano ezenzekelayo. Ibhodi entsha ye-microcontroller iyacwangciswa ngolwimi lwe-C. Ikhithi yophuhliso edibanisa neVisual Studio ibonelelwa ngale njongo.
ICortex M0+ ayinayo iprosesa yenombolo edadayo. Lo mba ulawulwa nge-SDK yenkqubo yolwimi lwe-C. I-MicroPython port iyafumaneka kwikhadi lokuphatha isoftware yolwimi lwePython. Kwinkomfa yeNtetho ye-tinyML, izithethi ziqaphele ukuba amakhadi amaninzi anikwe amandla yi-RP2040 system-on-a-chip ayafuneka. Ke iinkampani ezifana ne-Adafruit, i-Pimoroni, kunye ne-Sparkfun zikhulula i-hardware yazo, uninzi lwazo oluneempawu ezingafumanekiyo kwiPi Pico.
U-Upton uthe kulo msitho iqela langaphakathi leSicelo esiDityanisiweyo seeSekethe (ASIC) yeRaspberry Pi isebenza kwiphindaphindo elilandelayo.
Ukunikezelwa kwe U-Upton ucebisa ukuba iqela libonakala ligxile kwii-accelerators zokukhanya kwizicelo zokufunda koomatshini bamandla asezantsi kakhulu. Ebudeni bentetho yakhe e-Upton, wabonisa isilayidi esinomxholo othi “Ulwalathiso Lwekamva.” Isilayidi sibonisa iibhodi ezintathu zesizukulwana sangoku "Pi Silicon", ezimbini zazo zivela kumaqabane ebhodi, i-MicroMod RP2040 esuka kwi-SparkFun kunye ne-Nano RP2040 Connect esuka kwi-Arduino.
Owesithathu uvela kwi-ArduCam, umenzi weekhamera ezisekelwe kwi-platform ye-Raspberry Pi. I-ArduCam okwangoku isebenza kwi-ArduCam Pico4ML edibanisa ukufundwa komatshini, ikhamera, imakrofoni kunye nemisebenzi yokubonisa kwibhokisi yePico.
Inqaku lokugqibela libonisa ukuba yintoni iprojekthi ezayo, enokuthi ifike kwimo ye-accelerators yokukhanya, mhlawumbi i-4 ukuya kwi-8 accumulations multiple (MAC) ngomjikelezo wewashi. Kwintetho yakhe, u-Upton wathi "kunokwenzeka ukuba kubekho elinye icandelo le-silicon elivela kwi-Raspberry Pi."
Okokugqibela, ukuba unomdla wokwazi okungakumbi ngale nguqulo intsha, unokujonga iinkcukacha Kule khonkco ilandelayo.
