Alibaba, yog ib lub tuam txhab loj tshaj plaws hauv Suav teb, tshaj tawm qhov kev tshawb pom ntawm kev txhim kho ntsig txog XuanTie E902, E906, C906 thiab C910 processor cores, tsim los ntawm 64-ntsis RISC-V kev qhia teeb tsa. XuanTie's qhib cores yuav tsim nyob rau hauv cov npe tshiab OpenE902, OpenE906, OpenC906 thiab OpenC910.
Cov schematics, cov lus piav qhia txog cov khoom siv hauv Verilog, simulator, thiab cov ntaub ntawv tsim qauv nrog tau tshaj tawm rau ntawm GitHub raws li daim ntawv tso cai Apache 2.0. Cov qauv ntawm GCC thiab LLVM compilers, Glibc tsev qiv ntawv, Binutils toolkit, U-Boot bootloader, thiab lub kernel hloov kho rau kev siv nrog XuanTie chips tau tshaj tawm cais. Linux, OpenSBI (RISC-V Supervisor Binary Interface) interface, ib lub platform rau kev tsim cov embedded Linux-Yocto systems, nrog rau cov patches rau kev tso tawm lub platform Android.
XuanTie C910, lub zog tshaj plaws ntawm cov chips qhib, yog tsim los ntawm T-Head faib siv 12 nm txheej txheem thev naus laus zis hauv 16-core variant ua haujlwm ntawm 2.5 GHz. Lub nti qhov kev ua tau zoo hauv kev ntsuas Coremark nce mus txog 7.1 Coremark / MHz, uas zoo dua rau ARM Cortex-A73 processors. Alibaba tau tsim tag nrho ntawm 11 qhov sib txawv RISC-V chips, uas ntau dua 2.5 billion tau tsim tawm, thiab lub tuam txhab tab tom ua haujlwm los tsim kom muaj ib qho ecosystem kom nce qib ntawm RISC-V architecture tsis yog rau IoT li xwb, tab sis kuj rau lwm hom kev siv computer.
Ua ib qho kev ceeb toom, RISC-V muab cov lus qhia qhib thiab yooj ywm, ua rau muaj peev xwm tsim cov microprocessors rau txhua daim ntawv thov yam tsis tas yuav muaj cov nqi them lossis cov nqe lus siv. RISC-V ua rau muaj peev xwm tsim cov SoCs thiab processors qhib tag nrho. Tam sim no, ntau lub kaum ob hom microprocessor cores, SoCs, thiab cov chips uas twb muaj lawm tab tom raug tsim raws li RISC-V specification los ntawm ntau lub tuam txhab thiab cov zej zog nyob rau hauv ntau daim ntawv tso cai dawb (BSD, MIT, Apache 2.0). Cov txheej txheem ua haujlwm nrog kev txhawb nqa RISC-V zoo suav nrog GNU / Linux.Linux (tam sim no txij li Glibc 2.27, binutils 2.30, gcc 7, thiab kernel tso tawm) Linux 4.15), FreeBSD thiab OpenBSD.
Ntxiv rau RISC-V, Alibaba tseem tab tom tsim cov tshuab raws li ARM64 architecture. Piv txwv li, ib txhij nrog kev tshawb pom ntawm XuanTie thev naus laus zis, lub server tshiab SoC Yitian 710 tau qhia, muaj 128 tus tswv ARMv9 cores ua haujlwm ntawm zaus ntawm 3.2 GHz. Lub nti muaj 8 DDR5 lub cim xeeb raws thiab 96 PCIe 5.0 kab. Cov nti tau tsim los siv 5 nm txheej txheem thev naus laus zis, uas ua rau nws tuaj yeem ua ke txog 628 billion transistors ntawm 60 mm² substrate. Hais txog kev ua tau zoo, Yitian 710 yog kwv yees li 20% sai dua li qhov ceev tshaj plaws ARM chips, thiab kwv yees li 50% ntau dua hauv kev siv hluav taws xob.
