Alibaba, imodzi mwamakampani akuluakulu aku China a IT, adalengeza za kupezeka kwazinthu zokhudzana ndi ma processor a XuanTie E902, E906, C906 ndi C910, omwe adamangidwa pamaziko a kamangidwe ka 64-bit RISC-V. Ma cores otseguka a XuanTie adzapangidwa pansi pa mayina atsopano OpenE902, OpenE906, OpenC906 ndi OpenC910.
Zithunzi, mafotokozedwe a magawo a hardware ku Verilog, simulator ndi zolemba zotsagana nazo zimasindikizidwa pa GitHub pansi pa chilolezo cha Apache 2.0. Osindikizidwa padera ndi mitundu ya opanga GCC ndi LLVM osinthidwa kuti azigwira ntchito ndi tchipisi XuanTie, laibulale ya Glibc, zida za Binutils, U-Boot loader, Linux kernel, OpenSBI (RISC-V Supervisor Binary Interface), nsanja yopanga ophatikizidwa machitidwe a Linux Yocto, komanso zigamba zoyendetsera nsanja ya Android.
XuanTie C910, yamphamvu kwambiri ya tchipisi zotseguka, imapangidwa ndi gawo la T-Head pogwiritsa ntchito ukadaulo wa 12 nm mumitundu 16 yogwira ntchito pa 2.5 GHz. Kuchita kwa chip mu mayeso a Coremark kumafika 7.1 Coremark/MHz, yomwe ili yoposa mapurosesa a ARM Cortex-A73. Alibaba yapanga ma chips 11 osiyanasiyana a RISC-V, omwe oposa 2.5 biliyoni apangidwa kale, ndipo kampaniyo ikuyesetsa kukhazikitsa chilengedwe kuti ipititse patsogolo kamangidwe ka RISC-V osati pazida za IoT zokha, komanso zida za IoT. mitundu ina yamakina a makompyuta.
Kumbukirani kuti RISC-V imapereka makina otseguka komanso osinthika owongolera makina omwe amalola kuti ma microprocessors amangidwe kuti agwiritse ntchito mosasamala popanda kulipidwa kapena kuyika mikhalidwe yogwiritsidwa ntchito. RISC-V imakupatsani mwayi wopanga ma SoC ndi mapurosesa otseguka. Pakadali pano, kutengera tsatanetsatane wa RISC-V, makampani osiyanasiyana ndi madera omwe ali ndi zilolezo zosiyanasiyana zaulere (BSD, MIT, Apache 2.0) akupanga mitundu ingapo ya ma microprocessor cores, SoCs ndi tchipisi topangidwa kale. Makina ogwiritsira ntchito omwe ali ndi chithandizo chapamwamba kwambiri cha RISC-V akuphatikiza GNU/Linux (yomwe ilipo kuyambira kutulutsidwa kwa Glibc 2.27, binutils 2.30, gcc 7 ndi Linux kernel 4.15), FreeBSD ndi OpenBSD.
Kuphatikiza pa RISC-V, Alibaba ikupanganso machitidwe otengera kamangidwe ka ARM64. Mwachitsanzo, nthawi imodzi ndi kupezeka kwa matekinoloje a XuanTie, seva yatsopano ya SoC Yitian 710 idayambitsidwa, yomwe ili ndi ma cores 128 a ARMv9 omwe amagwira ntchito pafupipafupi 3.2 GHz. Chipchi chili ndi ma 8 DDR5 memory channels ndi 96 PCIe 5.0 misewu. Chipchi chinapangidwa pogwiritsa ntchito ukadaulo wa 5 nm, womwe udapangitsa kuti azitha kuphatikiza ma transistors pafupifupi 628 biliyoni pagawo la 60 mmΒ². Pankhani ya magwiridwe antchito, Yitian 710 ndi pafupifupi 20% mwachangu kuposa tchipisi ta ARM tachangu, komanso pafupifupi 50% yogwira ntchito bwino pakugwiritsa ntchito mphamvu.
