Hordhac PCIe 6.0

Ururka PCI-SIG ayaa ku dhawaaqay siidaynta rasmiga ah ee PCIe 6.0 tafatirka heerka v1.0, isagoo ku dhawaaqay dhamaystirka.

Sii wadida heshiiska, xawaaraha xawaaruhu wuxuu sii wadaa inuu labanlaabo, ilaa 128GB/s(unidirectional) x16, iyo tan iyo markii tignoolajiyada PCIe ay u ogolaato socodka xogta laba-geesoodka ah ee buuxa, wadarta wax soo saarka labada dhinac waa 256GB/s.Sida qorshuhu yahay, waxaa jiri doona tusaalooyin ganacsi 12 ilaa 18 bilood ka dib daabacaadda heerka, oo ku saabsan 2023, waa inay marka hore ku jiraan goobta server-ka.PCIe 6.0 waxay imaan doontaa dhamaadka sanadka ugu horrayn, oo leh xajmi dhan 256GB/s

Dib ugu noqoshada tignoolajiyada lafteeda, PCIe 6.0 waxaa loo arkaa inuu yahay isbeddelka ugu weyn ee PCIe ee ku dhawaad ​​​​20-sano ee taariikhda.Si daacadnimo loo sheego, PCIe 4.0/5.0 waa wax ka beddel yar oo 3.0 ah, sida 128b/130b codaynta oo ku salaysan NRZ (Non-Return-to-Zero).

PCIe 6.0 waxay u wareegtay PAM4 pulse AM signaling, 1B-1B codeing, hal calaamad waxay noqon kartaa afar codayn (00/01/10/11), labanlaaban kii hore, taas oo u oggolaanaysa ilaa 30GHz soo noqnoqda.Si kastaba ha noqotee, sababta oo ah calaamadda PAM4 ayaa ka jilicsan NRZ, waxay ku qalabaysan tahay FEC habka sixitaanka qaladka hore si loo saxo khaladaadka calaamadaha ee isku xirka loona hubiyo daacadnimada xogta

Marka lagu daro PAM4 iyo FEC, tignoolajiyada ugu dambeysa ee ugu weyn ee PCIe 6.0 waa isticmaalka FLIT (Cutubka Xakamaynta Socodka) ee codaynta heerka macquulka ah.Dhab ahaantii, PAM4, FLIT ma aha tiknoolajiyad cusub, 200G + 200G + ultra-xawaaraha sare ee Ethernet ayaa muddo dheer la dabaqay, taas oo PAM4 ay ku guuldareysatay inay kor u qaaddo baaxadda weyn ee sababta ayaa ah in kharashka lakabka jireed uu aad u sarreeyo.

Intaa waxaa dheer, PCIe 6.0 waxay ahaanaysaa mid dib u soconaysa.

PCIe 6.0 waxay sii wadaa inay labanlaabto xawaaraha I / O ilaa 64GT / s marka loo eego dhaqanka, kaas oo lagu dabaqo xawaaraha dhabta ah ee PCIe 6.0X1 bandwidth unidirectional ee 8GB/s, PCIe 6.0 × 16 bandwidth unidirectional of 128GB/s, iyo pcie 6.0 × 16 bandwidth laba jiho ah oo ah 256GB/s.PCIe 4.0 x4 SSDS, oo si weyn loo isticmaalo maanta, waxay u baahan doontaa oo kaliya PCIe 6.0 x1 si ay u sameyso.

PCIe 6.0 waxay sii wadi doontaa 128b/130b codaynta lagu soo bandhigay xilligii PCIe 3.0.Marka lagu daro CRC-da asalka ah, waxaa xiiso leh in la ogaado in borotokoolka kanaalka cusub uu sidoo kale taageerayo PAM-4 codeed ee loo isticmaalo Ethernet iyo GDDR6x, beddelaya PCIe 5.0 NRZ.Xog dheeraad ah ayaa lagu soo ururin karaa hal kanaal isla waqti isku mid ah, iyo sidoo kale habka saxda ah ee khaladaadka xogta ee hooseeya ee loo yaqaan sixitaanka qaladka hore (FEC) si loo sameeyo kordhinta xajmiyeedka mid macquul ah oo la isku halayn karo.

Dad badan ayaa laga yaabaa inay su'aalaan, PCIe 3.0 bandwidth inta badan lama isticmaalo, PCIe 6.0 waa maxay isticmaalka?Sababtoo ah kororka codsiyada gaajaysan ee xogta, oo ay ku jiraan sirdoonka macmal ah, kanaalka IO ee leh heerarka gudbinta degdega ah ayaa sii kordhaya inay noqdaan baahida macaamiisha suuqa xirfadeed, iyo baaxadda sare ee tignoolajiyada PCIe 6.0 waxay si buuxda u furi kartaa waxqabadka alaabada u baahan IO sare. bandwidth oo ay ku jiraan dardargeliyayaasha, barashada mashiinka iyo codsiyada HPC.PCI-SIG waxay sidoo kale rajeyneysaa inay ka faa'iideysato warshadaha baabuurta ee sii kordhaya, taas oo ah meel kulul oo loogu talagalay semiconductors, kooxda PCI-Special Interest Group waxay sameeyeen koox cusub oo ka shaqeysa farsamada PCIe si ay diiradda u saaraan sidii loo kordhin lahaa qaadashada tignoolajiyada PCIe ee baabuurta. warshadaha, sida kororka baahida loo qabo baaxadda deegaanka ay muuqato.Si kastaba ha noqotee, sida microprocessor-ka, GPU, aaladda IO iyo kaydinta xogta lagu xidhi karo kanaalka xogta, PC si loo helo taageerada interface PCIe 6.0, soosaarayaasha Motherboard-ku waxay u baahan yihiin inay taxaddar dheeraad ah muujiyaan si ay u habeeyaan fiilada xamili kara calaamadaha xawaaraha sare leh, iyo soosaarayaasha chipset sidoo kale waxay u baahan yihiin inay sameeyaan diyaargarow ku habboon.Afhayeenka Intel ayaa diiday inuu sheego goorta taageerada PCIe 6.0 lagu dari doono aaladaha, laakiin wuxuu xaqiijiyay in macaamiisha Alder Lake iyo dhinaca server-ka Sapphire Rapids iyo Ponte Vecchio ay taageeri doonaan PCIe 5.0.NVIDIA sidoo kale way diiday inay sheegto goorta PCIe 6.0 la soo bandhigi doono.Si kastaba ha noqotee, BlueField-3 Dpus ee xarumaha xogta waxay horey u taageereen PCIe 5.0;Specific-ka PCIe kaliya wuxuu qeexayaa shaqooyinka, waxqabadka, iyo cabirrada loo baahan yahay in lagu fuliyo lakabka jireed, laakiin ma qeexdo sida kuwan loo hirgeliyo.Si kale haddii loo dhigo, soosaarayaashu waxay naqshadayn karaan qaab dhismeedka lakabka jirka ee PCIe iyadoo loo eegayo baahiyahooda iyo xaaladaha dhabta ah si loo hubiyo shaqeynta!Soosaarayaasha fiilooyinka ayaa ciyaari kara boos badan!
