I-Alibaba, enye yeenkampani ezinkulu ze-IT zaseTshayina, ibhengeze ukufunyanwa kophuhliso olunxulumene ne-XuanTie E902, E906, C906 kunye ne-C910 processor cores, eyakhelwe kwisiseko se-64-bit ye-RISC-V ye-architecture ye-architecture. Iicores ezivulekileyo zikaXuanTie ziya kuphuhliswa phantsi kwamagama amatsha i-OpenE902, i-OpenE906, i-OpenC906 kunye ne-OpenC910.
Imizobo, iinkcazo zeeyunithi ze-hardware kwi-Verilog, i-simulator kunye namaxwebhu oyilo olukhaphayo apapashwa kwi-GitHub phantsi kwelayisensi ye-Apache 2.0. Zipapashwe ngokwahlukeneyo iinguqulelo ze-GCC kunye ne-LLVM compilers ezilungiselelwe ukusebenza ngeechips ze-XuanTie, ilayibrari ye-Glibc, i-Binutils toolkit, i-U-Boot loader, i-Linux kernel, i-OpenSBI (i-RISC-V Supervisor Binary Interface), iqonga lokudala Iinkqubo zeLinux ezizinzisiweyo iYocto, kunye neepetshi zokusebenzisa iqonga le-Android.
I-XuanTie C910, eyona nto inamandla kakhulu kwiichips ezivulekileyo, iveliswa yicandelo le-T-Head usebenzisa iteknoloji yenkqubo ye-12 nm kwi-16-core variant esebenza kwi-2.5 GHz. Ukusebenza kwe-chip kuvavanyo lwe-Coremark kufikelela kwi-7.1 Coremark / MHz, ephezulu kune-ARM Cortex-A73 processors. I-Alibaba iphuhlise iitshiphusi ezili-11 ezahlukeneyo ze-RISC-V, apho ngaphezulu kwe-2.5 yeebhiliyoni sele zivelisiwe, kwaye inkampani isebenza ukuseka inkqubo yendalo ukuqhubela phambili ulwakhiwo lwe-RISC-V kungekuphela nje kwizixhobo ze-IoT, kodwa nakwizinto eziphilayo. ezinye iintlobo zeenkqubo zekhompyutha.
Khumbula ukuba i-RISC-V ibonelela ngenkqubo yomyalelo womatshini ovulekileyo kunye noguquguqukayo ovumela ukuba i-microprocessors yakhelwe usetyenziso olungenasizathu ngaphandle kokufuna imali yokuhlawula okanye ukubeka iimeko zokusetyenziswa. I-RISC-V ikuvumela ukuba wenze ii-SoCs ezivuleleke ngokupheleleyo kunye neeprosesa. Okwangoku, ngokusekwe kwinkcazo ye-RISC-V, iinkampani ezahlukeneyo kunye noluntu oluphantsi kweelayisensi ezahlukeneyo zasimahla (BSD, MIT, Apache 2.0) ziphuhlisa iindidi ezininzi ze-microprocessor cores, ii-SoCs kunye neechips esele zenziwe. Iinkqubo zokusebenza ezinenkxaso ephezulu ye-RISC-V ziquka i-GNU/Linux (ekhoyo ukususela ekukhutshweni kwe-Glibc 2.27, i-binutils 2.30, i-gcc 7 kunye ne-Linux kernel 4.15), i-FreeBSD kunye ne-OpenBSD.
Ukongeza kwi-RISC-V, i-Alibaba iphinda iphuhlise iinkqubo ezisekwe kwi-ARM64 ye-architecture. Umzekelo, ngaxeshanye kunye nokufunyanwa kobuchwepheshe be-XuanTie, iseva entsha ye-SoC Yitian 710 yaziswa, iqulethe i-128 proprietary ARMv9 cores esebenza kwi-frequency ye-3.2 GHz. I-chip ineendlela zememori ze-8 DDR5 kunye ne-96 PCIe 5.0 imizila. I-chip yaveliswa kusetyenziswa iteknoloji yenkqubo ye-5 nm, eyenza ukuba kube lula ukudibanisa malunga ne-628 yezigidigidi ze-transistors kwi-60 mmΒ² substrate. Ngokubhekiselele ekusebenzeni, i-Yitian 710 imalunga nama-20% ngokukhawuleza kuneetshiphusi ze-ARM ezikhawulezayo, kwaye malunga ne-50% esebenzayo ngakumbi ekusebenziseni amandla.
