Isingeniso PCIe 6.0

Inhlangano ye-PCI-SIG imemezele ukukhishwa okusemthethweni kwe-PCIe 6.0 ejwayelekile ye-v1.0, ememezela ukuqedwa.

Ngokuqhubeka nomhlangano, isivinini somkhawulokudonsa siyaqhubeka siphindeka kabili, size sifike ku-128GB/s(unidirectional) ku-x16, futhi njengoba ubuchwepheshe be-PCIe buvumela ukugeleza kwedatha ye-bidirectional ye-duplex egcwele, ingqikithi yokuphuma kwezindlela ezimbili ingu-256GB/s.Ngokwalolu hlelo, kuzoba nezibonelo zezentengiselwano ezinyangeni eziyi-12 kuye kweziyi-18 ngemuva kokushicilelwa kwezinga, okungaba ngu-2023, kufanele kube kupulatifomu yeseva kuqala.I-PCIe 6.0 izofika ekupheleni konyaka ekuqaleni, ne-bandwidth engu-256GB/s

Emuva kubuchwepheshe uqobo, i-PCIe 6.0 ithathwa njengoshintsho olukhulu kakhulu emlandweni we-PCIe weminyaka ecishe ibe ngama-20.Ukukhuluma iqiniso, i-PCIe 4.0/5.0 iwushintsho oluncane lwe-3.0, olufana nombhalo wekhodi we-128b/130b osuselwe ku-NRZ (Non-Return-to-Zero).

I-PCIe 6.0 ishintshele ku-PAM4 pulse AM signaling, 1B-1B ikhodi, isignali eyodwa ingaba ikhodi yombhalo emine (00/01/10/11), iphinde kabili eyangaphambili, ivumele imvamisa efika ku-30GHz.Kodwa-ke, ngenxa yokuthi isignali ye-PAM4 intekenteke kakhulu kune-NRZ, ifakwe indlela yokulungisa iphutha le-FEC phambili ukuze ilungise amaphutha esignali kusixhumanisi nokuqinisekisa ubuqotho bedatha.

Ngaphezu kwe-PAM4 ne-FEC, ubuchwepheshe bokugcina obukhulu ku-PCIe 6.0 ukusetshenziswa kombhalo wekhodi we-FLIT (Flow Control Unit) ezingeni elinengqondo.Eqinisweni, i-PAM4, i-FLIT akuyona ubuchwepheshe obusha, ku-200G + Ethernet ye-ultra-high-speed sekuyisikhathi eside isetshenziswe, i-PAM4 yehlulekile ukukhuthazwa okukhulu kwesizathu ukuthi izindleko zesendlalelo somzimba ziphezulu kakhulu.

Ngaphezu kwalokho, i-PCIe 6.0 ihlala ibuyela emuva iyahambisana.

I-PCIe 6.0 iyaqhubeka nokuphinda kabili i-bandwidth ye-I/O ku-64GT/s ngokwesiko, esetshenziswa kumkhawulokudonsa wangempela we-PCIe 6.0X1 we-8GB/s, i-PCIe 6.0 × 16 umkhawulokudonsa ongaqondile we-128GB/s, kanye ne-pcie 6.0 × 16 umkhawulokudonsa ophindwe kabili we-256GB/s.I-PCIe 4.0 x4 SSDS, esetshenziswa kabanzi namuhla, izodinga kuphela i-PCIe 6.0 x1 ukuze ikwenze.

I-PCIe 6.0 izoqhubeka nombhalo wekhodi we-128b/130b owethulwe enkathini ye-PCIe 3.0.Ngokungeziwe ku-CRC yasekuqaleni, kuyathakazelisa ukuqaphela ukuthi umthetho olandelwayo omusha wesiteshi futhi usekela umbhalo wekhodi we-PAM-4 osetshenziswa ku-Ethernet naku-GDDR6x, esikhundleni se-PCIe 5.0 NRZ.Idatha eyengeziwe ingapakishwa esiteshini esisodwa ngesikhathi esifanayo, kanye nendlela yokulungiswa kwamaphutha edatha yokubambezeleka okuphansi eyaziwa ngokuthi ukulungiswa kwamaphutha angaphambili (i-FEC) ukuze kwenziwe umkhawulokudonsa okhulayo ufezeke futhi uthembeke.

Abantu abaningi bangase babuze, i-PCIe 3.0 bandwidth ngokuvamile ayisetshenziswanga, i-PCIe 6.0 iyini ukusetshenziswa?Ngenxa yokwanda kwezinhlelo zokusebenza ezilambele idatha, okuhlanganisa ubuhlakani bokwenziwa, iziteshi ze-IO ezinamazinga okudlulisela ngokushesha ziya ngokuya ziba isidingo samakhasimende emakethe yobungcweti, kanye nomkhawulokudonsa ophezulu wobuchwepheshe be-PCIe 6.0 ungavula ngokugcwele ukusebenza kwemikhiqizo edinga i-IO ephezulu. umkhawulokudonsa ohlanganisa ama-accelerator, ukufunda ngomshini kanye nezinhlelo zokusebenza ze-HPC.I-PCI-SIG futhi inethemba lokuzuza embonini yezimoto ekhulayo, okuyindawo eshisayo yama-semiconductors, kanti i-PCI-Special Interest Group isungule iqembu elisha le-PCIe Technology elizogxila ekukhuliseni ukwamukelwa kobuchwepheshe be-PCIe ezimotweni. imboni, njengoba ukwanda kwesidingo se-ecosystem somkhawulokudonsa kubonakala.Kodwa-ke, njengoba i-microprocessor, i-GPU, idivayisi ye-IO kanye nokugcinwa kwedatha kungaxhunywa esiteshini sedatha, i-PC ukuze ithole ukusekelwa kwe-interface ye-PCIe 6.0, abakhiqizi be-motherboard badinga ukuqaphela okwengeziwe ukuze bahlele ikhebula elingakwazi ukuphatha izimpawu zesivinini esikhulu, kanye nabakhiqizi be-chipset nabo badinga ukwenza amalungiselelo afanele.Umkhulumeli we-Intel unqabile ukusho ukuthi ukusekelwa kwe-PCIe 6.0 kuzokwengezwa nini kumadivayisi, kodwa ukuqinisekisile ukuthi umthengi i-Alder Lake kanye nohlangothi lweseva iSapphire Rapids kanye nePonte Vecchio zizoyisekela i-PCIe 5.0.I-NVIDIA iphinde yenqabile ukusho ukuthi izokwethulwa nini i-PCIe 6.0.Nokho, i-BlueField-3 Dpus yezikhungo zedatha isivele isekela i-PCIe 5.0;I-PCIe Spec icacisa kuphela imisebenzi, ukusebenza, namapharamitha okudingeka asetshenziswe kusendlalelo esibonakalayo, kodwa ayicacisi ukuthi lokhu kufakwa kanjani.Ngamanye amazwi, abakhiqizi bangaklama uhlaka olubonakalayo lwe-PCIe ngokwezidingo zabo kanye nezimo zangempela zokuqinisekisa ukusebenza!Abakhiqizi bekhebula bangadlala indawo eyengeziwe!
