Zimbalwa izinsuku ezedlule imininingwane ikhishwe mayelana ukuhlanganiswa kwemininingwane eveza uhlobo lwesoftware ne-hardware esetshenziswa ku-SpaceX, amasistimu okusebenza asetshenziswa kurokhethi le-Falcon 9 kuhlobo lwehadiwe elisetshenziswayo. Lonke lolu lwazi lususelwa kokucashunwe okushiwo ngabasebenzi be-SpaceX ezingxoxweni ezahlukahlukene.
Ngenxa yalokho, ngaphakathi kolwazi oludaluliwe Kushiwo ukuthi amasistimu ashumekiwe we-Falcon 9 asebenzisa i-Linux eyenziwe lula y amakhompyutha amathathu ayimpinda ngokuya ngamaprosesa ajwayelekile omndeni okubili okubili x86.
Ngaphezu kokuthi ngaphakathi kwemishini esetshenzisiwe, ukusetshenziswa kwama-chips akhethekile akudingeki ngokuvikelwa okukhethekile kwemisebe yamakhompyutha we-Falcon 9, ngoba isigaba sokuqala sokubuya asikho esikhaleni esingaphandle isikhathi eside futhi ukuncipha kwezinhlelo kwanele.
Ingxenye engazaziswanga uqobo, imayelana nokuthi iyiphi i-chip ethile esetshenziswayo e-Falcon 9, kepha ukusetshenziswa kwe-CPU ejwayelekile kungumkhuba ojwayelekile, ngokwesibonelo, i-Intel 80386SX 20 MHz CPU ekuqaleni yayihlonyelwe i-International Space Station control multiplexer ne-demultiplexer (C&C MDM) kanye nezincwadi zokubhalela ze-HP ZBook zisetshenziswa emsebenzini wansuku zonke Ama-ISS 15s ane- Ukusatshalaliswa kwe- "Debian" Linux, i-Scientific Linux noma i-Windows 10.
Okwezinhlelo zeLinux, zisetshenziswa njengamatheminali akude we-C & C MDM neWindows ye i-leer ama-imeyili, hlola iwebhu bese uzijabulisa (Iqiniso elinelukuluku lokwazi, kepha liyaqondakala uma kukhulunywa ngokuvikela amapulatifomu amakhulu kusuka "ephutheni lomuntu" elidumile manje).
Ngokuqondene ne Isoftware yokulawula indiza yeFalcon 9 ibhalwe ku-C / C ++ futhi isebenza ngokufana kukhompyutha ngayinye kulawa amathathu.
Kudingeka amakhompyutha amathathu angasebenzi ukuqinisekisa izinga elifanele lokuthembeka ngenxa yezipele eziningi. Umphumela wesinqumo ngasinye uqhathaniswa nomphumela otholwe kwamanye amakhompyutha, futhi kuphela uma ama-node amathathu ehlangana, umyalo wamukelwa yi-microcontroller elawula ama-motors kanye nama-rudder rudders.
Kungani ama-processor amathathu? Lokhu kungenxa yokuthi, njengoba kuchaziwe ku-StackExchange Space Exploration, i-SpaceX isebenzisa uhlelo lwe-Actor-Judge ukuhlinzeka ukuphepha ngokudilizwa. Kulolu hlelo, isikhathi ngasinye lapho kwenziwa isinqumo, kuqhathaniswa nemiphumela yamanye ama-cores. Uma kukhona ukungavumelani, isinqumo siyalahlwa bese inqubo iqala kabusha. Kulapho kuphela lapho iprosesa ngalinye lithola impendulo efanayo lapho umyalo uthunyelwa kuma-microcontroller e-PowerPC.
Laba balawuli, abathatha izinqumo zama-rocket motors kanye namaphiko kunethiwekhi, bathola imiyalo emithathu kunqubo ngayinye ye-x86. Uma zonke izintambo zomyalo ezintathu ziyefana, khona-ke i-microcontroller isebenzisa umyalo, kepha uma eyodwa yalezi zinto ezintathu ingalungile, isilawuli silandela umyalo wokugcina olungile ongenhla. Uma izinto zingahambi kahle ngokuphelele, i-Falcon 9 iyishaya indiva imiyalo evela ku-chip ehlulekayo.
Ithimba elihlanganisa abantu ababalelwa ku-35 ithuthukise isoftware ethile yezinhlelo ugibele i-Falcon 9, i-rocket simulator, amathuluzi wokuhlola ikhodi yokulawula indiza, ikhodi yokuxhumana kanye nesoftware yokuhlaziya izindiza ezivela ezinhlelweni zomhlaba.
Ngaphambi kokukhishwa kwangempela kwesoftware yokulawula indiza kanye nemishini, ihlolwa kusimulator, lapho kulingiswa izimo ezahlukahlukene zokundiza nezimo eziphuthumayo.
Umkhumbi-mkhathi ophethwe i-Crew Dragon uhanjiswe naku-orbit sebenzisa isoftware yendiza yeLinux ne-C ++. Izazi ze-interface zisebenza nazo kwenziwa ngesisekelo se- Vula uhlelo lokusebenza olususelwa kuwebhu ku-Chromium. Ukuphathwa kudlula esikrinini sokuthinta, kepha uma kwenzeka kwehluleka kunekhibhodi yokulawula umkhumbi-mkhathi.
Ekugcineni, uma ufuna ukwazi kabanzi ngolwazi oluqoqiwe, ungathinta inothi yoqobo ngokuya kusixhumanisi esilandelayo.
