Dhawaan hoosta gogosha Linux Foundation mashruuc cusub ayaa la sameeyay, Isbahaysiga CHIPS "Qalabka Guud ee Isku-xidhka, Processor-ka iyo Nidaamyada"(Qalabka guud ee loogu talagalay isdhexgalka, processor-yada iyo nidaamyada), oo loogu talagalay in lagu dhiirrigeliyo nidaamyada qalabka furan iyo horumariyo xalal ku saleysan qaab dhismeedka RISC-V.
Aasaasayaasha tan mashruuc cusub "Isbahaysiga CHIPS" waa Google, SiFive, Western Digital iyo Esperanto Technologies. Isbahaysiga CHIPS waxaa loogu talagalay inuu isku muujiyo madal dhexdhexaad ah oo madax bannaan.
Muxuu yahay Isbahaysiga CHIPS?
Madalkan u oggolaan doonaa soo saarayaasha qalabka kala duwan (Qalabka) waxay si wadajir ah u horumarin karaan mashaariicdooda si ay u abuuraan processor furan oo ka baxsan fulinta sanduuqa iyo hal nidaam (chip) oo loo adeegsado naqshadaha RISC-V.
RISC-V (oo loogu magacdaray "Risk-Five") waa qalab casri ah oo lagu dejiyo qaab dhismeedka (ISA) oo ku saleysan qaab u eg RISC. Si ka duwan noocyada waxbarista badankood, RISC-Vs waa lacag la'aan waana furan tahay waxaana loo isticmaali karaa ujeeddo kasta.
U oggolow qof kasta inuu naqshadeeyo, soo saaro oo iibiyo qalabka 'RISC-V' iyo barnaamijyada 'RISC-V'. In kasta oo aysan ahayn naqshad dhismeedka ugu horreeya ee ISA, laakiin waa mid muhiim ah maxaa yeelay waxaa loogu talagalay inay faa'iido u yeelato qalab ballaaran.
In kastoo hadda abaabulka RISC-V Foundation wuxuu la macaamilaa kaliya qaabeynta laga bilaabo tilmaamaha la dejiyey, laakiin ma khuseyso hirgelinta gaarka ah.
Taasi waa sababta aasaaskan cusub u dhashay iyo hawsha Isbahaysiga CHIPS waa in loo diyaariyo naqshad jilicsan oo furan oo loogu talagalay qalabka moobiilka, nidaamyada kombiyuutarka, elektarooniga macaamiisha iyo internetka waxyaabaha.
"Wada shaqeynta furan waxaa si isdaba joog ah loo muujiyey inay ka caawineyso warshadaha inay dardar geliyaan waqtiga suuqa, ayna gaaraan dayactirka muddada dheer, ayna abuuraan heerarka dhabta ah," ayuu yiri Mike Dolan, madaxweyne ku xigeenka barnaamijyada istiraatiijiyadeed ee aasaaska Linux. "
Sida tabarucaada bilowga ah, aasaasayaashii Isbahaysiga CHIPS waxay soo bandhigeen mashaariicdan soo socda ee horumarka wadajirka ah.
SweRV Core
Este waa processor-ka RISC-V oo 32-bit ah oo ay soo saartay shirkadda Western Digital. Chip wuxuu ku shaqeeyaa inta jeer ee 1,8 GHz, Waxaa lagu dhisay qaab dhismeed leh 8-heer dhuumaha labada jir (2-way superscale) waxaana loogu talagalay wax soo saar iyadoo la adeegsanayo tiknoolajiyada nidaamka 28nm CMOS.
Jadwalka, dukumiintiyada, moodooyinka CAD, naqshadeynta jubbada, microcode, iyo hirgelinta buuxda ee luuqadda Verilog waxay ku furan yihiin shatiga Apache 2.0
OmniXtend
Es borotokool shabakadeed oo bixiya isku xirnaanta kaydinta markii lagu wareejinayo xogta Ethernet.
OmniXtend ayaa sameyn doona wuxuu kuu ogolaanayaa inaad si toos ah fariimaha ugu dhaafsato keydka processor-ka waxaana loo isticmaali karaa in lagu xiro xawaareyaasha kala duwan, aaladaha keydinta, aaladaha xusuusta (NVDIMMs) iyo isdhexgalka shabakadaha ee SoC, iyo sidoo kale in la abuuro nidaamyo leh jajabyo badan oo RISC-V ah. Mashruuca waxaa wareejiyay Western Digital.
UVM
Google waxay wareejisay hirgelinta Habka Xaqiijinta Caalamiga (UVM) tijaabinta walbahaarka walxaha xisaabinta RISC-V iyo qalabka naqshadeynta.
Gaar ahaan, waxaan ka hadleynaa koronto-dhaliye socodka socodka ah, oo loo isticmaali karo in lagu aqoonsado cilladaha iyo dhibaatooyinka ka jira dhismaha iyo heerka microarchitecture.
Shirkadda Shan, oo ay aasaaseen hal abuurayaasha RISC-V waxay diyaariyeen noocii ugu horreeyay ee processor ee ku saleysan RISC-V, marka lagu daro sameynta luqad cusub oo tilmaanta qalabka 'Chisel' oo ay weheliso UC Berkeley.
Ku wareejin doonaa matoorka 'RocketChip SoC' mashruuca, sii-deynta bilowga ah ee is-waafajinta TileLink ee isku xidhka qaybaha SoC iyo qaab-dhismeedka Diblomaasiyadda.
Iyada oo qayb ka ah mashruuca wadajirka ah, SiFive waxay sidoo kale sii wadi doontaa horumarinta luqadda Chisel iyo soo bandhigidda ku meel gaarka ah ee FIRRTL.
Hadda, Iyada oo ku saleysan qeexitaanka RISC-V, shirkado iyo jaaliyado kala duwan oo hoos yimaada shatiyada bilaashka ah ee bilaashka ah (BSD, MIT, Apache 2.0) ayaa horumarinaya 21 nooc oo micros microroscessor cores ah:
10 SoCs iyo 6 jajab oo horey ganacsi ahaan loo heli jiray (SiFive FE310-G000, SiFive Freedom U540, GreenWaves GAP 8, Kendryte K210, NXP RV32M1 iyo RavenRV32).
Taageerada RISC-V waxay jirtay ilaa iyo markii ay sii daayeen Glibc 2.27, binutils 2.30, gcc 7, iyo Linux kernel 4.15.
