Intangiriro PCIe 6.0

Umuryango PCI-SIG watangaje ko hasohotse kumugaragaro PCIe 6.0 ibipimo ngenderwaho v1.0, bitangaza ko byarangiye.

Gukomeza amahwaniro, umuvuduko wumurongo ukomeza gukuba kabiri, kugeza kuri 128GB / s (uterekejwe) kuri x16, kandi kuva tekinoroji ya PCIe yemerera amakuru yuzuye-duplex ibyerekezo byombi, inzira ebyiri zose zinjira ni 256GB / s.Ukurikije gahunda, hazabaho ingero zubucuruzi nyuma y amezi 12 kugeza 18 nyuma yo gutangaza ibipimo ngenderwaho, nko muri 2023, bigomba kubanza kuba kumurongo wa seriveri.PCIe 6.0 izaza mu mpera zumwaka hakiri kare, hamwe nubunini bwa 256GB / s

Tugarutse ku ikoranabuhanga ubwaryo, PCIe 6.0 ifatwa nkimpinduka nini mumateka ya PCIe mumyaka hafi 20.Mvugishije ukuri, PCIe 4.0 / 5.0 ni ihinduka rito rya 3.0, nka kodegisi ya 128b / 130b ishingiye kuri NRZ (Kudasubira kuri Zeru).

PCIe 6.0 yahinduye kuri PAM4 pulse AM ikimenyetso, 1B-1B code, ikimenyetso kimwe gishobora kuba kodegisi enye (00/01/10/11), zikubye kabiri, zemerera inshuro zigera kuri 30GHz.Ariko, kubera ko ikimenyetso cya PAM4 cyoroshye kurusha NRZ, gifite ibikoresho bya FEC byambere byo gukosora amakosa yo gukosora amakosa yibimenyetso mumurongo no kwemeza ubudakemwa bwamakuru.

Usibye PAM4 na FEC, tekinoroji yanyuma iheruka muri PCIe 6.0 ni ugukoresha FLIT (Flow Control Unit) kodegisi kurwego rwumvikana.Mubyukuri, PAM4, FLIT ntabwo ari tekinolojiya mishya, muri 200G + ultra-yihuta yihuta ya Ethernet imaze igihe kinini ikoreshwa, PAM4 yananiwe guteza imbere cyane impamvu ni uko igiciro cyumubiri kiri hejuru cyane.

Mubyongeyeho, PCIe 6.0 ikomeza gusubira inyuma.

PCIe 6.0 ikomeje gukuba kabiri umurongo wa I / O kugeza kuri 64GT / s ukurikije umuco, ikoreshwa kuri PCIe 6.0X1 umurongo mugari wa 8GB / s, PCIe 6.0 × 16 umurongo uterekanwa wa 128GB / s, na pcie 6.0 × 16 byerekezo byerekezo ya 256GB / s.PCIe 4.0 x4 SSDS, ikoreshwa cyane muri iki gihe, izakenera gusa PCIe 6.0 x1 kubikora.

PCIe 6.0 izakomeza kodegisi ya 128b / 130b yatangijwe mugihe cya PCIe 3.0.Usibye CRC yumwimerere, birashimishije kumenya ko protocole nshya ya protocole nayo ishyigikira kodegisi ya PAM-4 ikoreshwa muri Ethernet na GDDR6x, igasimbuza PCIe 5.0 NRZ.Ibisobanuro byinshi birashobora gupakirwa mumurongo umwe mugihe kingana, kimwe nuburyo bwihuse bwo gukosora amakuru azwi nkikosora ryimbere ikosora (FEC) kugirango ubwiyongere bwumurongo bushoboka kandi bwizewe.

Abantu benshi barashobora kwibaza, PCIe 3.0 umurongo mugari ntukoreshwa, PCIe 6.0 nikihe?Bitewe n'ubwiyongere bwa porogaramu zashonje amakuru, harimo n'ubwenge bw'ubukorikori, imiyoboro ya IO ifite umuvuduko wo kohereza byihuse igenda iba icyifuzo cy'abakiriya ku isoko ry'umwuga, kandi umurongo mwinshi wa tekinoroji ya PCIe 6.0 urashobora gufungura byimazeyo imikorere y'ibicuruzwa bisaba IO yo hejuru. umurongo mugari urimo kwihuta, kwiga imashini hamwe na HPC.PCI-SIG yizera kandi ko izungukira mu nganda zikoresha amamodoka agenda yiyongera, akaba ari ahantu hashyushye ku bice bya semiconductor, kandi PCI-idasanzwe ishinzwe inyungu yashizeho itsinda rishya ry’ikoranabuhanga rya PCIe ryibanda ku buryo bwo kongera ikoreshwa rya tekinoloji ya PCIe mu modoka. inganda, nkuko urusobe rwibinyabuzima rwiyongera ku muyoboro ugaragara.Ariko, nkuko microprocessor, GPU, igikoresho cya IO hamwe nububiko bwamakuru bishobora guhuzwa numuyoboro wamakuru, PC kugirango ibone inkunga ya interineti ya PCIe 6.0, abakora ikibaho cyababyeyi bakeneye kwitonda cyane kugirango bategure umugozi ushobora gukoresha ibimenyetso byihuta, n'abakora chipset nabo bakeneye gukora imyiteguro ijyanye.Umuvugizi wa Intel yanze kuvuga igihe inkunga ya PCIe 6.0 izongerwa ku bikoresho, ariko yemeza ko umuguzi Alder Lake hamwe na seriveri ya Sapphire Rapids na Ponte Vecchio bazashyigikira PCIe 5.0.NVIDIA yanze kandi kuvuga igihe PCIe 6.0 izatangirwa.Ariko, BlueField-3 Dpus kubigo byamakuru bimaze gushyigikira PCIe 5.0;PCIe yihariye igaragaza gusa imikorere, imikorere, nibipimo bigomba gushyirwa mubikorwa kurwego rwumubiri, ariko ntibisobanura uburyo bwo kubishyira mubikorwa.Muyandi magambo, abayikora barashobora gushushanya imiterere yumubiri wa PCIe ukurikije ibyo bakeneye hamwe nibisabwa kugirango barebe imikorere!Abakora insinga barashobora gukina umwanya munini!
