Alibaba, imwe yemakambani makuru eChinese IT, yakazivisa kuwanikwa kwezvinoitika zvine chekuita neXuanTie E902, E906, C906 uye C910 processor cores, yakavakirwa pahwaro hwe64-bit RISC-V yekuraira seti yekuvaka. XuanTie's open cores ichagadzirwa pasi pemazita matsva OpenE902, OpenE906, OpenC906 uye OpenC910.
Madhayagiramu, tsananguro yemayuniti ehardware muVerilog, simulator uye anoperekedza dhizaini zvinyorwa zvinoburitswa paGitHub pasi peApache 2.0 rezinesi. Akadhindwa akapatsanurwa mavhezheni eGCC neLLVM compiler akagadziridzwa kushanda neXuanTie chip, iyo Glibc raibhurari, Binutils toolkit, U-Boot loader, Linux kernel, OpenSBI (RISC-V Supervisor Binary Interface), chikuva chekugadzira. yakamisikidzwa Linux masisitimu Yocto, uye zvakare zvigamba zvekumhanyisa iyo Android chikuva.
XuanTie C910, iyo yakanyanya simba yemachipi akavhurika, inogadzirwa neiyo T-Head division ichishandisa 12 nm process tekinoroji mune gumi nematanhatu-core variant inoshanda pa16 GHz. Kuita kwechip muCoremark bvunzo kunosvika 2.5 Coremark/MHz, iri nani kune ARM Cortex-A7.1 processors. Alibaba yakagadzira gumi nerimwe akasiyana RISC-V machipisi, ayo anopfuura bhiriyoni maviri nemazana mashanu akatogadzirwa, uye kambani iri kushanda kumisa ecosystem kuti ienderere mberi neRISC-V yekuvakisa kwete yemidziyo yeIoT chete, asiwo ye. mamwe marudzi emakomputa masisitimu.
Rangarira kuti RISC-V inopa yakavhurika uye inochinjika yekuraira sisitimu inobvumira mamicroprocessors kuvakirwa zvikumbiro zvemanyorero pasina kuda mari kana kuisa mamiriro ekushandisa. RISC-V inokutendera iwe kuti ugadzire akavhurika SoCs uye processors. Parizvino, zvichibva pane zvakatemwa zveRISC-V, makambani akasiyana nenharaunda dziri pasi pemarezinesi emahara akasiyana (BSD, MIT, Apache 2.0) vari kugadzira akati wandei akasiyana e microprocessor cores, SoCs uye akatogadzirwa machipisi. Masisitimu anoshanda ane emhando yepamusoro rutsigiro rweRISC-V anosanganisira GNU/Linux (iripo kubva pakaburitswa Glibc 2.27, binutils 2.30, gcc 7 uye Linux kernel 4.15), FreeBSD uye OpenBSD.
Pamusoro peRISC-V, Alibaba zvakare iri kugadzira masisitimu anoenderana neiyo ARM64 yekuvaka. Semuenzaniso, panguva imwe chete nekuwanikwa kweXuanTie tekinoroji, sevha nyowani SoC Yitian 710 yakaunzwa, ine 128 proprietary ARMv9 cores inoshanda pafrequency ye3.2 GHz. Iyo chip ine 8 DDR5 ndangariro nzira uye 96 PCIe 5.0 nzira. Iyo chip yakagadzirwa uchishandisa 5 nm process tekinoroji, iyo yakaita kuti ikwanise kubatanidza anenge 628 bhiriyoni transistors pane 60 mmΒ² substrate. Panyaya yekushanda, Yitian 710 inosvika makumi maviri muzana nekukurumidza kupfuura machipisi eARM anokurumidza, uye anosvika makumi mashanu muzana anoshanda zvakanyanya mukushandisa simba.
