Alibaba, enye yeenkampani ezinkulu ze-IT eTshayina, ulwazi olusanda kubhengezwa malunga nophuhliso olunxulumene ne iicores zeprosesa «XuanTie E902, E906, C906 kunye neC910»Ezisekelwe kwi-64-bit ye-architecture ye-RISC-V iseti yomyalelo.
Uphuhliso lwaba baqhubekekisi luphantsi kweXuanTie ikhowudi yomthombo ovulekileyo kwaye iya kuphuhliswa ngamagama amatsha i-OpenE902, i-OpenE906, i-OpenC906 kunye ne-OpenC910.
Ngokumalunga nolwazi olukhutshiweyo imizobo, iinkcazo zeebhloko ze-hardware zichazwe ngolwimi lwaseVerilog, isifanisi kunye namaxwebhu eprojekthi eziqhotyoshelweyo zipapashwa kwi-GitHub phantsi kwelayisensi ye-Apache 2.0.
Ukongeza koku kwaye ipapashwe ngokwahlukeneyo, iye yalungiselelwa ukusebenza ngeetships ze-XuanTie ze-GCC kunye neenguqulelo ze-LLVM compiler, ilayibrari ye-Glibc yezixhobo ze-Binutils, i-U-the Boot loader, i-Linux kernel, i-OpenSBI i-middleware interface (i-Supervisor Binary Interface RISC-la V oomatshini), iqonga lokwakha iinkqubo ezifakwe kwi-Linux Yocto Project kunye neepatches zokuqalisa iqonga le-Android.
Kwinkomfa, uZhang ugxininise inkqubela yakhe ekuphuhliseni i-RISC-V, equka ezine ezine-high-performance RISC-V cores XuanTie E902, E906, C906 kunye neC910. U-Alibaba ubhengeze ukuba uvule ezo cores eziza kuhamba phantsi kwegama elitsha elibizwa ngokuba yi-OpenE902, OpenE906, OpenC906 kunye ne-OpenC910 ngokulandelelanayo. Ezo cores ngoku ziyafumaneka kwi-T-Head Semiconductor GitHub.
U-Alibaba uthi uthumele ngaphezu kwe-2.500 yezigidigidi zezo IPs. “Namhlanje samkela iRISC-V. Sine-11 ezahlukeneyo ze-RISC-V chips kwaye sizibonile ezo mveliso zixhasa iinkqubo ezininzi zokusebenza. Iyakhawuleza ukuba liqela elikhulu lemveliso. Sisebenzela ukudala i-ecosystem kwishishini kunye namaqabane ethu, kungekhona kuphela kwicala le-IoT kodwa nakwi-computing side, kuya kuba nenkqubela phambili enkulu kwaye namhlanje i-Alibaba kwi-RISC-V ikhokela ihlabathi. Sinabathengi abaninzi kunye namakhulu amahlakani akha i-ecosystem kunye nathi, ”wongeze watsho uZhang.
I-XuanTie C910, eyona chip inamandla evulekileyo, yenziwe licandelo le-T-Head. usebenzisa inkqubo ye-12nm kwinguqulo ye-16-core, kunye frequency 2,5 GHz. Ukusebenza kwe-chip kuvavanyo lwe-Coremark kufikelela kwi-7.1 Coremark / MHz, ephezulu kune-ARM Cortex-A73 processors. Lilonke, i-Alibaba iphuhlise iitshiphusi ezili-11 ezahlukeneyo zeRISC-V, apho ngaphezulu kwe-2.5 yeebhiliyoni zeekopi sele zikhutshiwe, kwaye inkampani isebenza ukuseka inkqubo yendalo ukuqhubela phambili ulwakhiwo lwe-RISC-V hayi nje kwizixhobo ze-IoT, kodwa kwakhona. kwezinye iintlobo zeenkqubo zekhompyutha.
Kulungiselelwe abo bangakhange bazi RISC-V, ndingakuxelela ukuba oku ibonelela ngenkqubo yomyalelo kamatshini ovulekileyo kwaye bhetyebhetye ukuba ivumela ukwenza microprocessors ngezicelo ezingafunekiyo ngaphandle kokufuna imali yokuhlawula okanye ukubeka imiqathango yokusetyenziswa. I-RISC-V ikuvumela ukuba wenze ii-SoCs ezivuleleke ngokupheleleyo kunye neeprosesa.
Okwangoku, ngokusekwe kwinkcazo yeRISC-V, iinkampani ezahlukeneyo kunye noluntu phantsi kweemvume ezahlukeneyo zasimahla (BSD, MIT, Apache 2.0) baphuhlisa ishumi elinambini lahlukeneyo le-microprocessor cores, i-SoC kunye neetshiphusi esele zenziwe. Umgangatho ophezulu we-RISC-V weenkqubo zokusebenza ezixhaswayo ziquka i-GNU / Linux (ekhoyo ukususela kwi-Glibc 2.27, i-binutils 2.30, i-gcc 7, kunye ne-Linux 4.15 kernel), i-FreeBSD, kunye ne-OpenBSD.
Ukongeza kwi-RISC-V, i-Alibaba ikwaphuhlisa iinkqubo ezisekwe kuyilo lwe-ARM64. Umzekelo, ngaxeshanye kunye nokufunyanwa kwetekhnoloji yeXuanTie, iseva entsha ye-Yitian 710 SoC ibonisiwe, equlathe i-128 ARMv9 cores yoyilo lwethu, esebenza rhoqo kwi-3.2 GHz.
I-chip ixhotyiswe ngeeshaneli ezi-8 zememori ye-DDR5 kunye neendlela ze-96 ze-PCIe 5.0. Itshiphu yaveliswa kusetyenziswa inkqubo yeteknoloji ye-5nm, eyenze ukuba kwenzeke ukudibanisa malunga nama-60 eebhiliyoni zeetransistors kwi-628mm² substrate. Ngokubhekiselele ekusebenzeni, i-Yitian 710 igqwesa i-chips ze-ARM ezikhawulezayo malunga ne-20%, kwaye ngokubhekiselele kusetyenziso lwamandla lusebenza kakuhle malunga ne-50%.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo, ungajonga iinkcukacha Kule khonkco ilandelayo.
