Alibaba yakaunza itsva RISC-V XuanTie processors

Alibaba, imwe yemakambani makuru eIT muChina, ichangobva kuziviswa ruzivo nezve budiriro yayo ine chekuita ne macores e processors «XuanTie E902, E906, C906 uye C910»Izvo zvakavakirwa pa64-bit dhizaini yeRISC-V yekuraira set.

Magadzirirwo ema processors aya ari pasi peXuanTie open source code uye achagadzirwa aine mazita matsva OpenE902, OpenE906, OpenC906 uye OpenC910.

Nezve ruzivo rwakaburitswa dhayagiramu, tsananguro dzezvivharo zvehardware zvinotsanangurwa mumutauro weVerilog, iyo simulator uye zvinyorwa zveprojekiti zvakabatanidzwa zvakaburitswa paGitHub pasi peApache 2.0 rezinesi.

Pamusoro peizvi uye zvakaburitswa zvakasiyana, yakagadziridzwa kushanda neXuanTie chips GCC uye LLVM compiler shanduro, Glibc raibhurari yeBinutils maturusi, U-the Boot loader, Linux kernel, OpenSBI middleware interface (Supervisor Binary Interface RISC-la V michina), ipuratifomu yekugadzira yakadzamirirwa masisitimu yakavakirwa paLinux Yocto Project uye zvakare zvigamba zvekutanga Android chikuva.

Pamusangano uyu, Zhang akasimbisa kufambira mberi kwake mukuvandudza kweRISC-V, iyo inosanganisira yayo ina yepamusoro-soro yeRISC-V cores XuanTie E902, E906, C906 uye C910. Alibaba yakazivisa kuti yakavhura iwo macores ayo zvino achaenda pasi pezita idzva rinonzi OpenE902, OpenE906, OpenC906 uye OpenC910 zvakateerana. Iwo macores ave kuwanikwa paT-Head Semiconductor GitHub.

Alibaba anoti yakatumira zvinopfuura 2.500 bhiriyoni yeaya IPs. "Nhasi tiri kutora RISC-V. Isu takave negumi nerimwe akasiyana RISC-V machipi uye takaona izvo zvigadzirwa zvichitsigira akawanda anoshanda masisitimu. Iri kukurumidza kuita boka guru rezvigadzirwa. Tiri kushanda kuti tigadzire ecosystem muindasitiri nevatinodyidzana navo, kwete kudivi reIoT chete asiwo kudivi remakomputa, kuchave nekufambira mberi kukuru uye nhasi Alibaba muRISC-V ari kutungamira pasirese. Tine vatengi vazhinji uye mazana evadyidzani vanovaka ecosystem pamwe chete nesu, ”Zhang akawedzera.

Iyo XuanTie C910, iyo yakasimba kwazvo yakavhurika chip, inogadzirwa neiyo T-Head division. uchishandisa 12nm maitiro mune 16-core vhezheni, ine frequency ye2,5 GHz. Kuita kwechip muCoremark bvunzo kunosvika 7.1 Coremark / MHz, iri pamusoro peiyo ARM Cortex-A73 processors. Pakazara, Alibaba yakagadzira gumi nerimwe akasiyana RISC-V machipisi, ayo anopfuura bhiriyoni maviri nemazana mashanu emakopi akatoburitswa, uye kambani iri kushanda kumisa ecosystem kufambisira mberi iyo RISC-V yekuvakisa kwete yemidziyo yeIoT chete, asiwo. kune mamwe marudzi emakombuta masisitimu.

Kune avo vachiri kusaziva RISC-V, ndinogona kukuudzai kuti izvi inopa yakavhurika muchina kuraira system uye flexible kuti inobvumira kugadzira microprocessors zvekushandisa zvisina tsarukano pasina kuda kubhadharwa kana kuisa mamiriro ekushandiswa. RISC-V inokutendera iwe kuti ugadzire akavhurika SoCs uye processors.

Parizvino, zvichibva pane iyo RISC-V yakatarwa, makambani akasiyana siyana nenharaunda pasi pemarezinesi akasiyana emahara (BSD, MIT, Apache 2.0) vari kugadzira gumi nemaviri akasiyana e microprocessor cores, SoC uye machipisi akatogadzirwa. Yepamusoro-mhando RISC-V inotsigirwa masisitimu anoshanda anosanganisira GNU / Linux (iripo kubva Glibc 2.27, binutils 2.30, gcc 7, uye Linux 4.15 kernel), FreeBSD, uye OpenBSD.

Pamusoro peRISC-V, Alibaba zvakare inogadzira masisitimu akavakirwa pane iyo ARM64 yekuvaka. Semuenzaniso, panguva imwe chete nekuwanikwa kweXuanTie tekinoroji, itsva Yitian 710 SoC server inoratidzwa, ine 128 ARMv9 cores yedhizaini yedu, inoshanda pafrequency ye3.2 GHz.

Iyo chip ine 8 chiteshi cheDDR5 ndangariro uye 96 nzira dzePCIe 5.0. Iyo chip yakagadzirwa uchishandisa 5nm process tekinoroji, izvo zvakaita kuti zvikwanise kubatanidza zvakatenderedza 60 bhiriyoni transistors pane 628mm² substrate. Panyaya yekushanda, Yitian 710 inokunda machipisi eARM anokurumidza kusvika makumi maviri kubva muzana, uye maererano nekushandiswa kwesimba rinonyanya kushanda ne20%.

Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
