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 duab kos duab, cov lus piav qhia ntawm cov khoom siv kho vajtse hauv Verilog, lub simulator thiab cov ntaub ntawv tsim qauv tau luam tawm ntawm GitHub raws li Apache 2.0 daim ntawv tso cai. Cais luam tawm yog versions ntawm GCC thiab LLVM compilers yoog rau kev ua haujlwm nrog XuanTie chips, Glibc tsev qiv ntawv, Binutils toolkit, U-Boot loader, Linux ntsiav, OpenSBI (RISC-V Supervisor Binary Interface), lub platform tsim embedded Linux systems Yocto, thiab kuj thaj ua rau thaj rau kev khiav ntawm Android platform.
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.
Nco qab tias RISC-V muab cov lus qhia qhib thiab hloov pauv lub tshuab uas tso cai rau cov microprocessors tsim rau cov ntawv thov tsis tas yuav tsum tau muaj nuj nqis lossis ua rau muaj kev cuam tshuam rau kev siv. RISC-V tso cai rau koj los tsim qhib SoCs thiab cov txheej txheem. Tam sim no, raws li RISC-V specification, cov tuam txhab sib txawv thiab cov zej zog nyob rau hauv ntau daim ntawv tso cai pub dawb (BSD, MIT, Apache 2.0) tab tom tsim ntau lub kaum os ntawm microprocessor cores, SoCs thiab twb tau tsim cov chips. Cov tshuab ua haujlwm nrog kev txhawb nqa zoo rau RISC-V suav nrog GNU / Linux (tam sim no txij li kev tshaj tawm ntawm Glibc 2.27, binutils 2.30, gcc 7 thiab Linux ntsiav 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 mmΒ² 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.
