I-Alibaba, enye yezinkampani ezinkulu zaseShayina ze-IT, imemezele ukutholwa kwentuthuko ehlobene nama-processor cores i-XuanTie E902, E906, C906 kanye ne-C910, eyakhelwe kusisekelo sesethi ye-64-bit RISC-V yesethi yezakhiwo. Ama-cores avuliwe we-XuanTie azothuthukiswa ngaphansi kwamagama amasha i-OpenE902, i-OpenE906, i-OpenC906 ne-OpenC910.
Imidwebo, izincazelo zamayunithi ezingxenyekazi zekhompuyutha ku-Verilog, isifanisi kanye nemibhalo yokuklama ehambisana naso kushicilelwa ku-GitHub ngaphansi kwelayisensi ye-Apache 2.0. Okushicilelwe ngokwehlukana izinguqulo ze-GCC kanye ne-LLVM compilers eziguqulelwe ukusebenza ngama-chips e-XuanTie, umtapo wezincwadi we-Glibc, ikhithi yamathuluzi ye-Binutils, isilayishi se-U-Boot, i-Linux kernel, i-OpenSBI (RISC-V Supervisor Binary Interface), inkundla yokwakha Amasistimu e-Linux ashumekiwe i-Yocto, kanye nama-patches okusebenzisa inkundla ye-Android.
I-XuanTie C910, enamandla kakhulu kuma-chips avulekile, ikhiqizwa yi-T-Head division isebenzisa ubuchwepheshe benqubo ye-12 nm ekuhlukeni kwe-16-core esebenza ku-2.5 GHz. Ukusebenza kwe-chip ekuhlolweni kwe-Coremark kufinyelela ku-7.1 Coremark/MHz, ephakeme kune-ARM Cortex-A73 processors. I-Alibaba isungule ingqikithi yama-chips e-RISC-V ayi-11 ahlukene, asekhiqiziwe angaphezu kwezigidigidi ezi-2.5, futhi inkampani isebenzela ukusungula uhlelo lwezemvelo ukuze kuthuthukiswe ukwakhiwa kwe-RISC-V hhayi kuphela kumadivayisi we-IoT, kodwa futhi ezinye izinhlobo zamasistimu ekhompyutha.
Khumbula ukuthi i-RISC-V ihlinzeka ngohlelo lokufundisa ngomshini oluvulekile noluguquguqukayo oluvumela ama-microprocessors ukuthi akhelwe izinhlelo zokusebenza ngokungafanele ngaphandle kokudinga izinkokhelo noma ukubeka izimo zokusebenzisa. I-RISC-V ikuvumela ukuthi udale ama-SoC namaphrosesa avuleke ngokuphelele. Njengamanje, ngokusekelwe ekucacisweni kwe-RISC-V, izinkampani ezahlukene nemiphakathi engaphansi kwamalayisense ahlukahlukene amahhala (i-BSD, i-MIT, i-Apache 2.0) zakha izinhlobo eziningana ezihlukene zama-microprocessor cores, ama-SoC kanye nama-chips asevele akhiqizwa. Amasistimu okusebenza anokusekelwa kwekhwalithi ephezulu kwe-RISC-V afaka i-GNU/Linux (ekhona kusukela kwakhishwa i-Glibc 2.27, binutils 2.30, gcc 7 kanye ne-Linux kernel 4.15), 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-SoC Yitian 710, equkethe ama-ARMv128 cores okuphathelene angu-9 asebenza ngemvamisa engu-3.2 GHz. I-chip ineziteshi zememori eziyi-8 DDR5 nemizila engu-96 PCIe 5.0. I-chip yakhiqizwa kusetshenziswa ubuchwepheshe benqubo ye-5 nm, okwenze kwaba nokwenzeka ukuhlanganisa ama-transistors angaba yizigidi eziyizinkulungwane ezingama-628 ku-60 mmΒ² substrate. Mayelana nokusebenza, i-Yitian 710 ishesha cishe ngo-20% kunama-chips e-ARM ashesha kakhulu, futhi cishe ngo-50% isebenza kahle kakhulu ekusebenziseni amandla.
