Ua hoʻolaha ʻo Alibaba, kekahi o nā hui IT Kina nui loa, i ka loaʻa ʻana o nā hanana e pili ana i ka XuanTie E902, E906, C906 a me C910 cores processor, i kūkulu ʻia ma ke kumu o ka 64-bit RISC-V instruction set architecture. E hoʻomohala ʻia nā cores wehe o XuanTie ma lalo o nā inoa hou OpenE902, OpenE906, OpenC906 a me OpenC910.
Hoʻopuka ʻia nā kiʻi, nā wehewehe ʻana o nā ʻāpana lako ma Verilog, kahi simulator a me nā palapala hoʻolālā e pili pū ana ma GitHub ma lalo o ka laikini Apache 2.0. Hoʻopuka kaʻawale ʻia nā mana o ka GCC a me LLVM compilers i hoʻololi ʻia no ka hana ʻana me nā chips XuanTie, ka hale waihona puke Glibc, ka pahu hana Binutils, ka U-Boot loader, ka Linux kernel, ka OpenSBI (RISC-V Supervisor Binary Interface), ke kahua no ka hana ʻana. hoʻokomo i nā ʻōnaehana Linux ʻo Yocto, a me nā pākia no ka holo ʻana i ka paepae Android.
ʻO XuanTie C910, ka mea ikaika loa o nā pahu hāmama, i hana ʻia e ka māhele T-Head me ka hoʻohana ʻana i ka ʻenehana kaʻina hana 12 nm i kahi ʻano 16-core e hana ana ma 2.5 GHz. ʻO ka hana o ka chip i ka hōʻike Coremark a hiki i ka 7.1 Coremark / MHz, ʻoi aku ka maikaʻi ma mua o nā kaʻina hana ARM Cortex-A73. Ua hoʻomohala ʻo Alibaba i 11 mau ʻāpana RISC-V ʻokoʻa, a ʻoi aku ka nui o 2.5 biliona i hana ʻia, a ke hana nei ka ʻoihana e hoʻokumu i kahi kaiaola e holomua hou i ka hoʻolālā RISC-V ʻaʻole wale no nā mea IoT, akā no nā mea hoʻi. nā ʻano ʻōnaehana kamepiula ʻē aʻe.
E hoʻomanaʻo i ka hāʻawi ʻana o RISC-V i kahi ʻōnaehana aʻoaʻo mīkini wehe a maʻalahi e hiki ai i nā microprocessors ke kūkulu ʻia no nā noi ʻokoʻa me ka ʻole o ke koi ʻana i nā aliʻi a i ʻole ke kau ʻana i nā kūlana i ka hoʻohana ʻana. ʻAe ʻo RISC-V iā ʻoe e hana i nā SoC a me nā kaʻina hana. I kēia manawa, e pili ana i ka kikoʻī RISC-V, nā hui like ʻole a me nā kaiāulu ma lalo o nā laikini manuahi like ʻole (BSD, MIT, Apache 2.0) e hoʻomohala nei i nā ʻano ʻokoʻa he nui o nā microprocessor cores, SoCs a i hana mua ʻia nā chips. ʻO nā ʻōnaehana hana me ke kākoʻo kiʻekiʻe no RISC-V e komo pū me GNU/Linux (i kēia manawa mai ka hoʻokuʻu ʻana o Glibc 2.27, binutils 2.30, gcc 7 a me ka Linux kernel 4.15), FreeBSD a me OpenBSD.
Ma kahi o RISC-V, ke hoʻomohala nei ʻo Alibaba i nā ʻōnaehana e pili ana i ka hoʻolālā ARM64. No ka laʻana, i ka manawa like me ka loaʻa ʻana o nā ʻenehana XuanTie, ua hoʻokomo ʻia kahi kikowaena hou SoC Yitian 710, nona nā cores ARMv128 proprietary 9 e hana ana ma ke alapine o 3.2 GHz. Loaʻa i ka chip he 8 DDR5 memo memo a me 96 PCIe 5.0 mau ala. Ua hana ʻia ka chip me ka ʻenehana kaʻina hana 5 nm, i hiki ai ke hoʻohui i kahi 628 biliona transistors ma kahi substrate 60 mm². Ma ke ʻano o ka hana, ʻo Yitian 710 ka 20% ʻoi aku ka wikiwiki ma mua o ka wikiwiki ARM chips, a ma kahi o 50% ʻoi aku ka maikaʻi i ka hoʻohana mana.
