I-SiFive X280 yi-multi-core ekwaziyo i-RISC-V iprosesa enezandiso ze-vector, ifanelekile kwizicelo ezifuna ukusebenza okuphezulu.
SiFive, umseki kunye nenkokeli yekhompyutha RISC-V, ibhengezwe kwiwebhusayithi yabo Yesikhokelo ekhethwe yi-NASA ukuba ukubonelela undoqo we iprosesa yekhompyutha yenqwelomoya ukusebenza okuphezulu (HPSC) isizukulwana esilandelayo.
Iprojekthi ye-NASA ye-HPSC iphuhlisa ubuchwepheshe bekhompyutha ye-flight ukuba iya kubonelela ngokuphindwe kalikhulu amandla okubambisa yeekhompyuter zanamhlanje zokubhabha. I-NASA yayibhengeze ngoJuni ukuba iprojekthi yayo ye-HPSC iya kubonelela ngeetshiphusi ezintsha eziyilwe nge-multicore, ezinee-cores ezininzi zokusetyenzwa kwi-chip nganye, kunye nesoftware esebenzayo ukuziqhuba.
Iqela leenjineli zeNASA lilawula indlela yokuphuhlisa i-HPSC kwaye inikezela ngolawulo lobugcisa bokuyila kunye nokuhanjiswa kweetshiphu zekhompyutha. lImitha yendalo esemajukujukwini iyonakalisa iindawo zombanes, ekugqibeleni kubangele ukuba basilele, kwaye nokwazisa iimpazamo kwizibalo ezenziwe apho. Ukongezelela, ngenxa yexesha elithathwayo ukuze imiqondiso ihambe ukusuka eMhlabeni isiya kwiindawo ezikude emajukujukwini, imisebenzi emininzi yasesibhakabhakeni imele yenziwe ngaphandle koncedo lwezixhobo ezisemhlabeni.
I-HPSC iya kuyilwa ngokukodwa ukuba ilingane kwisithuba kwaye iya kuba neempawu ezivumela ukuba isebenze kwaye ibonelele ngeziphumo ezithembekileyo ezinokuthi zisetyenziselwe eyona misebenzi ibaluleke kakhulu: umzekelo, ukuhla ngerobhothi okanye ukubhabha kwenye iplanethi, ukunceda oosomajukujuku ukuba bahambe bemke eMhlabeni, okanye ukusebenza kufutshane nemizimba emincinci inkqubo yelanga engaphandle.
Kuba amandla ombane asoloko enqongophele. I-HPSC yenzelwe ukuba ikwazi ukucubungula idatha amaxesha angama-100 ngokukhawuleza kuneekhompyuter zangoku ezilungele isithuba usebenzisa umlinganiselo ofanayo wamandla. Ikwavumela iifitsha ukuba zicinywe xa zingasetyenziswa kwaye amandla ancitshiswe xa engafunwa.
I-HPSC kulindeleke ukuba isetyenziswe phantse kuyo yonke imisebenzi yasemajukujukwini yexesha elizayo, ukusuka ekuhloleni iplanethi ukuya kwimishini yenyanga kunye neMartian. HPSC uizakusebenzisa i-280-core SiFive Intelligence X8 RISC-V vector core, kunye ne-SiFive RISC-V cores ezine ezongezelelweyo, ukwandisa umthamo wekhompyutha we-spacecraft yangoku ngamaxesha angama-100. Olu lwando lukhulu ekusebenzeni kwekhompyutha luya kunceda ukuvula amathuba amatsha kwizinto ezahlukeneyo zobuthunywa, ezinje ngeerovers ezizimeleyo, ukusetyenzwa kombono, ukubhabha emkhathini, iinkqubo zesikhokelo, unxibelelwano, kunye nezinye izicelo.
"Njengenkokeli yase-US kwi-semiconductors ye-RISC-V, sinelunda kakhulu ukuba sikhethwe yi-arhente ye-space ehamba phambili emhlabeni ukuba inike amandla ezona zicelo zibalulekileyo," kusho uJack Kang, usekela-mongameli ophezulu wophuhliso lwezoshishino kwi-SiFive. “I Besisoloko sisithi ngeSiFive, ikamva alinamida kwaye kuyasivuyisa ukubona ifuthe leenguqulelo zethu lidlulela ngaphaya kwesi sijikelezi-langa sethu. »
Isigqibo seNASA kunye neMicrochip ukukhetha uyilo lweRISC-V Asiyonto nje entsha eseti yomyalelo evulekileyo, esimahla yeRISC-V (ISA). Ngokutsho kukaKang, i-RISC-V ye-architecture es enye yazo izakuba nesiseko esikhulu somphuhlisi kwi-10, 15 okanye nakwi-20 iminyaka kwaye, ke, eKukubheja okukhuselekileyo kweNASA.
“Ukuba ujonga iitshiphusi zePowerPC zangoku, kudala sizisebenzisa amashumi eminyaka, bangaphi abaprogram bePowerPC abakhoyo ngoku?” utshilo. Ngelixa ngoku sisazi ulwakhiwo olusisiseko lwe-NASA's HPSC processor, kufuneka silinde kwaye sibone ukuba uyilo luya kuphunyezwa njani na ekugqibeleni, njengokuba kuya kusetyenziswa ukuqina kwemitha, kunye nayo nayiphi na enye inkqubo ekhethekileyo efunwa yi-semiconductors ebotshelelwe kwindawo.
Kuba zonke iintlobo zemishini ye-NASA zifuna ukukwazi ukusebenzisa i-computing, le chip ihlaziywayo inokuxhamla kuyo yonke imizamo ye-NASA yexesha elizayo, nokuba yimishini yesayensi esekwe emhlabeni, i-mission space, okanye iinqwelomoya zabantu.
Ukongeza, ubume obuvulekileyo kunye nentsebenziswano ye-RISC-V iya kuvumela uluntu olubanzi lwabaphuhlisi besoftware yezemfundo kunye nesayensi ukuba banikele kwaye baphuhlise i-algorithms yesayensi kunye nokusetyenziswa, kunye nokwandisa imisebenzi emininzi yemathematika, izihluzi, ukuguqula iilayibrari zeneural network, kunye nabanye.
