Alibaba, enye yezinkampani ezinkulu ze-IT eChina, ulwazi olusanda kumenyezelwa mayelana nentuthuko yalo ehlobene ne ama-cores of the processors «I-XuanTie E902, E906, C906 ne-C910»Okusekelwe ekwakhiweni kwe-64-bit yesethi yemiyalelo ye-RISC-V.
Intuthuko yalawa maphrosesa ingaphansi kwekhodi yomthombo ovulekile we-XuanTie futhi izothuthukiswa ngamagama amasha i-OpenE902, i-OpenE906, i-OpenC906 ne-OpenC910.
Mayelana nolwazi olukhishiwe imidwebo, izincazelo ze-hardware blocks zichazwe ngolimi lwe-Verilog, i-simulator kanye nemibhalo yephrojekthi okunamathiselwe kushicilelwe ku-GitHub ngaphansi kwelayisensi ye-Apache 2.0.
Ngaphezu kwalokhu futhi kwashicilelwa ngokwehlukana, iguqulelwe ukusebenza nezinguqulo ze-XuanTie chips GCC kanye ne-LLVM compiler, Umtapo wezincwadi we-Glibc wamathuluzi e-Binutils, i-U-the Boot loader, i-Linux kernel, i-OpenSBI middleware interface (imishini ye-Supervisor Binary Interface RISC-la V), inkundla yokwakha amasistimu ashumekiwe asekelwe ku-Linux Yocto Project kanye neziqephu zokuqalisa inkundla ye-Android.
Engqungqutheleni, uZhang wagqamisa inqubekelaphambili yakhe ekuthuthukisweni kwe-RISC-V, ehlanganisa ama-cores ayo amane asebenza kahle e-RISC-V XuanTie E902, E906, C906 kanye ne-C910. I-Alibaba imemezele ukuthi ivule lawo ma-cores manje azongena ngaphansi kwegama elisha elibizwa nge-OpenE902, OpenE906, OpenC906 kanye ne-OpenC910 ngokulandelana. Lawo ma-cores manje ayatholakala ku-T-Head Semiconductor GitHub.
I-Alibaba ithi ithumele ngaphezu kwe-2.500 billion yalawo ma-IP. “Namuhla semukela i-RISC-V. Sibe nama-chips angu-11 ahlukene e-RISC-V futhi siyibonile leyo mikhiqizo isekela amasistimu wokusebenza amaningi. Iba ngokushesha iqembu elikhulu lemikhiqizo. Sisebenzela ukudala i-ecosystem embonini nabalingani bethu, hhayi kuphela ohlangothini lwe-IoT kodwa futhi ohlangothini lwekhompyutha, kuzoba nenqubekelaphambili enkulu futhi namuhla i-Alibaba e-RISC-V ihola umhlaba. Sinamakhasimende amaningi kanye namakhulu ozakwethu abakha i-ecosystem kanye nathi, ”kwengeza uZhang.
I-XuanTie C910, i-chip enamandla kunazo zonke evulekile, yakhiwe yi-T-Head division. usebenzisa inqubo ye-12nm kunguqulo ye-16-core, imvamisa ye-2,5 GHz. Ukusebenza kwe-chip ekuhlolweni kwe-Coremark kufinyelela ku-7.1 Coremark / MHz, ephakeme kune-ARM Cortex-A73 processors. Sekukonke, i-Alibaba isungule ama-chips e-RISC-V ayi-11 ahlukene, sekukhishwe amakhophi angaphezu kwezigidi eziyizinkulungwane ezingama-2.5, futhi inkampani isebenza ukusungula uhlelo lwezemvelo ukuze kuthuthukiswe ukwakhiwa kwe-RISC-V hhayi nje kumadivayisi we-IoT, kodwa futhi. kwezinye izinhlobo zamasistimu ekhompyutha.
Okwalabo namanje abangazi I-RISC-V, ngingakutshela ukuthi lokhu inikeza uhlelo lokufundisa ngomshini ovulekile futhi kuyavumelana nalokho ivumela ukudala ama-microprocessors ngezicelo ezingafanele ngaphandle kokudinga ama-royalty noma ukubeka imibandela yokusebenzisa. I-RISC-V ikuvumela ukuthi udale ama-SoC namaphrosesa avuleke ngokuphelele.
Njengamanje, ngokusekelwe ekucacisweni kwe-RISC-V, izinkampani nemiphakathi eyahlukene ngaphansi kwamalayisensi ahlukahlukene amahhala (BSD, MIT, Apache 2.0) zakha ishumi nambili elihlukile lama-microprocessor cores, i-SoC nama-chips asevele ekhiqiziwe. Izinhlelo zokusebenza ezisekelwayo zekhwalithi ephezulu ze-RISC-V zifaka i-GNU / Linux (ekhona kusukela ku-Glibc 2.27, binutils 2.30, gcc 7, ne-Linux 4.15 kernel), i-FreeBSD, ne-OpenBSD.
Ngokungeziwe ku-RISC-V, i-Alibaba iphinde ithuthukise amasistimu asekelwe ekwakhiweni kwe-ARM64. Isibonelo, ngasikhathi sinye nokutholwa kobuchwepheshe be-XuanTie, kwethulwa iseva entsha ye-Yitian 710 SoC, equkethe ama-cores angu-128 ARMv9 omklamo wethu, osebenza ngemvamisa engu-3.2 GHz.
I-chip ifakwe iziteshi eziyi-8 zememori engu-DDR5 kanye nemizila engama-96 ye-PCIe 5.0. I-chip yakhiwe kusetshenziswa ubuchwepheshe benqubo ye-5nm, okwenze kwaba nokwenzeka ukuhlanganisa ama-transistors acishe abe yizigidi eziyizinkulungwane ezingama-60 ku-substrate engu-628mm². Mayelana nokusebenza, i-Yitian 710 idlula ama-ARM asheshayo cishe ngo-20%, futhi mayelana nokusetshenziswa kwamandla isebenza kahle kakhulu cishe ngo-50%.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
