Alibaba, e leng e 'ngoe ea lik'hamphani tse kholo ka ho fetisisa tsa China tsa IT, e phatlalalitse ho sibolloa ha tsoelo-pele e amanang le XuanTie E902, E906, C906 le C910 processor cores, e hahiloeng motheong oa meralo ea 64-bit RISC-V ea sete ea litaelo. Li-cores tse bulehileng tsa XuanTie li tla ntlafatsoa ka mabitso a macha OpenE902, OpenE906, OpenC906 le OpenC910.
Litšoantšo, litlhaloso tsa likarolo tsa hardware ho Verilog, simulator le litokomane tse tsamaeang le moralo li hatisoa ho GitHub tlas'a laesense ea Apache 2.0. E phatlalalitsoeng ka thoko ke liphetolelo tsa li-compilers tsa GCC le LLVM tse etselitsoeng ho sebetsa ka lichifi tsa XuanTie, laeborari ea Glibc, sesebelisoa sa Binutils, U-Boot loader, Linux kernel, OpenSBI (RISC-V Supervisor Binary Interface), sethala sa ho theha. Sistimi ea Linux e kenelletseng Yocto, le li-patches tsa ho tsamaisa sethala sa Android.
XuanTie C910, e matla ka ho fetisisa ea li-chips tse bulehileng, e hlahisoa ke karohano ea T-Head e sebelisa theknoloji ea ts'ebetso ea 12 nm ka 16-core variant e sebetsang ho 2.5 GHz. Ts'ebetso ea chip tekong ea Coremark e fihla ho 7.1 Coremark/MHz, e phahametseng li-processor tsa ARM Cortex-A73. Alibaba e hlahisitse kakaretso ea li-chips tse 11 tse fapaneng tsa RISC-V, tseo ho tsona tse fetang limilione tse likete tse 2.5 li seng li hlahisitsoe, mme k'hamphani e ntse e sebeletsa ho theha tikoloho ea tikoloho ho ntšetsa pele meralo ea RISC-V eseng feela bakeng sa lisebelisoa tsa IoT, empa le bakeng sa mefuta e meng ea sistimi ea komporo.
Hopola hore RISC-V e fana ka sistimi ea litaelo ea mochini e bulehileng le e tenyetsehang e lumellang li-microprocessors ho hahuoa bakeng sa lits'ebetso tse ikemetseng ntle le ho hloka meputso kapa ho beha maemo a ts'ebeliso. RISC-V e u lumella ho theha li-SoC le li-processor tse bulehileng ka botlalo. Hajoale, ho ipapisitsoe le tlhaloso ea RISC-V, lik'hamphani le sechaba se fapaneng tlasa lilaesense tse fapaneng tsa mahala (BSD, MIT, Apache 2.0) li ntse li nts'etsapele mefuta e mengata ea li-microprocessor cores, SoCs le lichifi tse seng li hlahisitsoe. Sistimi ea ts'ebetso e nang le ts'ehetso ea boleng bo holimo bakeng sa RISC-V e kenyelletsa GNU/Linux (e teng ho tloha ha ho lokolloa Glibc 2.27, binutils 2.30, gcc 7 le Linux kernel 4.15), FreeBSD le OpenBSD.
Ntle le RISC-V, Alibaba e boetse e nts'etsapele lits'ebetso tse ipapisitseng le meralo ea ARM64. Mohlala, ka nako e ts'oanang le ho sibolloa ha mahlale a XuanTie, ho ile ha hlahisoa seva e ncha ea SoC Yitian 710, e nang le li-cores tse 128 tsa ARMv9 tse sebetsang ka lebelo la 3.2 GHz. Chip e na le liteishene tsa memori tse 8 DDR5 le litselana tse 96 tsa PCIe 5.0. Chip e ile ea hlahisoa ho sebelisoa theknoloji ea 5 nm process, e entseng hore ho khonehe ho kopanya li-transistors tse ka bang limilione tse likete tse 628 holim'a substrate ea 60 mm². Mabapi le ts'ebetso, Yitian 710 e batla e le 20% ka potlako ho feta li-chips tsa ARM tse potlakileng, 'me hoo e ka bang 50% e sebetsa hantle haholoanyane tšebelisong ea matla.
