Alibaba, o se tasi o kamupani tele Saina IT, faalauiloaina le mauaina o atinae e faatatau i le XuanTie E902, E906, C906 ma C910 processor cores, fausia i luga o le faavae o le 64-bit RISC-V faatonuga seti fausaga. XuanTie's open cores o le a fausia i lalo o igoa fou OpenE902, OpenE906, OpenC906 ma OpenC910.
Ata, faʻamatalaga o iunite meafaigaluega i Verilog, o se simulator ma faʻamaumauga faʻapipiʻi faʻatasi o loʻo faʻasalalau ile GitHub i lalo ole laisene Apache 2.0. O loʻo faʻasalalau faʻasalalau faʻasalalauga o le GCC ma le LLVM tuʻufaʻatasia ua faʻatulagaina mo le galulue faatasi ma XuanTie chips, le Glibc library, le Binutils toolkit, le U-Boot loader, le Linux kernel, le OpenSBI (RISC-V Supervisor Binary Interface), le faʻavae mo le fatuina. fa'apipi'i Linux faiga Yocto, fa'apea fo'i ma patches mo le fa'agaioia o le Android platform.
XuanTie C910, le sili ona malosi o tupe meataalo tatala, e gaosia e le vaega T-Head e faʻaaoga ai le 12 nm tekinolosi faʻagasologa i se 16-core variant o loʻo galue ile 2.5 GHz. O le gaioiga a le pu i le suʻega Coremark e oʻo atu i le 7.1 Coremark / MHz, lea e sili atu nai lo le ARM Cortex-A73 processors. Ua fausia e Alibaba le aofaʻi o 11 eseese RISC-V chips, lea e sili atu nai lo le 2.5 piliona ua uma ona gaosia, ma o loʻo galue le kamupani e faʻavae se faʻalapotopotoga faʻanatura e faʻalautele atili ai le fausaga o le RISC-V e le gata mo masini IoT, ae faʻapea foi mo isi ituaiga faiga komepiuta.
Manatua o le RISC-V o loʻo tuʻuina atu se masini matala ma fetuutuunai faiga faʻatonuga e mafai ai ona fausia microprocessors mo talosaga faʻapitoa e aunoa ma le manaʻomia o totogi poʻo le faʻamalosia o aiaiga ile faʻaaogaina. RISC-V faʻatagaina oe e fatuina SoCs ma faʻagaioiga matala atoatoa. I le taimi nei, e faʻavae i luga o le RISC-V faʻamatalaga, kamupani eseese ma nuʻu i lalo o laisene saoloto eseese (BSD, MIT, Apache 2.0) o loʻo atinaʻeina le tele o le tele o fesuiaiga o microprocessor cores, SoCs ma ua uma ona gaosia meataalo. O faiga fa'aoga ma le lagolago maualuga mo le RISC-V e aofia ai le GNU/Linux (o lo'o i ai talu mai le fa'asalalauga o Glibc 2.27, binutils 2.30, gcc 7 ma le Linux kernel 4.15), FreeBSD ma OpenBSD.
I le faʻaopoopoga i le RISC-V, o loʻo atinaʻe foi e Alibaba faiga faʻavae i luga o le fausaga o le ARM64. Mo se faʻataʻitaʻiga, i le taimi lava e tasi ma le mauaina o tekinolosi XuanTie, na faʻaalia ai se server fou SoC Yitian 710, o loʻo iai 128 faʻapitoa ARMv9 cores o loʻo faʻaogaina i le taimi ole 3.2 GHz. O le pu o loʻo i ai 8 DDR5 memory channels ma 96 PCIe 5.0 lanes. O le pu na gaosia e faʻaaoga ai le 5 nm process technology, lea na mafai ai ona tuʻufaʻatasia pe tusa ma le 628 piliona transistors i luga o le 60 mm² substrate. I tulaga o le faʻatinoga, Yitian 710 e tusa ma le 20% sili atu le saoasaoa nai lo le televave o tupe meataalo ARM, ma e tusa ma le 50% sili atu le lelei i le faʻaaogaina o le eletise.
