Intangiriro kuri PCIe 5.0

• Intangiriro kuri PCIe 5.0

Ibisobanuro bya PCIe 4.0 byarangiye muri 2017, ariko ntibyashyigikiwe nu mbuga z’abaguzi kugeza igihe AMD ya 7nm Rydragon 3000 ikurikirana, kandi mbere ibicuruzwa gusa nka supercomputing, ububiko bwihuse bwo mu rwego rwo hejuru, hamwe n’ibikoresho by’urusobe byakoreshaga ikoranabuhanga rya PCIe 4.0.Nubwo tekinoroji ya PCIe 4.0 itarakoreshwa murwego runini, umuryango PCI-SIG umaze igihe kinini utezimbere PCIe 5.0 yihuse, igipimo cyibimenyetso cyikubye kabiri kuva kuri 16GT / s kugeza kuri 32GT / s, umurongo wa interineti urashobora kugera kuri 128GB / s, na verisiyo 0.9 / 1.0 ibisobanuro byarangiye.v0.7 verisiyo ya PCIe 6.0 isanzwe yoherejwe kubanyamuryango, kandi iterambere ryibipimo riri munzira.Igipimo cya pin ya PCIe 6.0 cyongerewe kugera kuri 64 GT / s, cyikubye inshuro 8 icya PCIe 3.0, kandi umurongo mugari wa x16 urashobora kuba munini kurenza 256GB / s.Muyandi magambo, umuvuduko wubu wa PCIe 3.0 x8 bisaba umuyoboro umwe gusa PCIe 6.0 kugirango ubigereho.Kubijyanye na v0.7, PCIe 6.0 yageze kubintu byinshi byatangajwe mbere, ariko gukoresha ingufu biracyakomeza gutera imbered, hamwe nibisanzwe byatangije ibikoresho bya L0p ibikoresho.Birumvikana ko nyuma yo gutangazwa muri 2021, PCIe 6.0 irashobora kuboneka mubucuruzi muri 2023 cyangwa 2024 hakiri kare.Kurugero, PCIe 5.0 yemejwe muri 2019, kandi ubu niho hari imanza zisaba

Ugereranije nibisanzwe byabanje gusobanurwa, PCIe 4.0 ibisobanuro byaje bitinze.PCIe 3.0 ibisobanuro byatangijwe muri 2010, nyuma yimyaka 7 hashyizweho PCIe 4.0, bityo ubuzima bwibisobanuro bya PCIe 4.0 bushobora kuba bugufi.By'umwihariko, abacuruzi bamwe batangiye gukora PCIe 5.0 PHY ibikoresho bifatika.

Ishyirahamwe PCI-SIG riteganya ko amahame yombi azabana mugihe runaka, kandi PCIe 5.0 ikoreshwa cyane cyane mubikoresho bikora cyane hamwe nibisabwa byinjira cyane, nka Gpus kuri AI, ibikoresho byurusobe, nibindi, bivuze ko PCIe 5.0 ari birashoboka cyane kugaragara muri data center, urusobe, hamwe na HPC ibidukikije.Ibikoresho bifite umuvuduko muke usabwa, nka desktop, birashobora gukoresha PCIe 4.0.

Kuri PCIe 5.0, igipimo cyibimenyetso cyongerewe kuva PCIe 4.0′s 16GT / s kigera kuri 32GT / s, kiracyakoresha kodegisi 128/130, kandi umurongo wa x16 wongerewe kuva kuri 64GB / s ugera kuri 128GB / s.

Usibye gukuba kabiri umurongo, PCIe 5.0 izana izindi mpinduka, guhindura igishushanyo cyamashanyarazi kugirango ubashe kunoza ibimenyetso, guhuza inyuma na PCIe, nibindi byinshi.Mubyongeyeho, PCIe 5.0 yateguwe hamwe nibipimo bishya bigabanya ubukererwe hamwe nibimenyetso byerekana intera ndende.

Ishyirahamwe PCI-SIG riteganya kuzuza verisiyo ya 1.0 yerekana muri Q1 uyu mwaka, ariko barashobora guteza imbere ibipimo, ariko ntibashobora kugenzura igihe igikoresho cya terefone cyinjijwe ku isoko, kandi biteganijwe ko PCIe yambere 5.0 ibikoresho bizatangira uyu mwaka, nibindi bicuruzwa bizagaragara muri 2020. Ariko, gukenera umuvuduko mwinshi byatumye umubiri usanzwe usobanura igisekuru kizaza cya PCI Express.Intego ya PCIe 5.0 nukwongera umuvuduko wibisanzwe mugihe gito gishoboka.Kubwibyo, PCIe 5.0 yashizweho kugirango yongere gusa umuvuduko kuri PCIe 4.0 ntayindi mikorere mishya ihambaye.

Kurugero, PCIe 5.0 ntabwo ishigikira ibimenyetso bya PAM 4 kandi ikubiyemo gusa ibintu bishya bikenewe kugirango ubushobozi bwa PCIe bushyigikire 32 GT / s mugihe gito gishoboka.

Ibibazo byibyuma

Ikibazo gikomeye mugutegura ibicuruzwa byo gushyigikira PCI Express 5.0 bizaba bifitanye isano n'uburebure bwumurongo.Umuvuduko wikimenyetso cyihuta, niko umutware wikurikiranwa ryibimenyetso byanyuze kubuyobozi bwa PC.Ubwoko bubiri bwangirika bwumubiri bugabanya urugero abajenjeri bashobora gukwirakwiza ibimenyetso bya PCIe:

· 1. Kumenyekanisha umuyoboro

· 2. Ibitekerezo bibera kumuyoboro bitewe no guhagarika inzitizi mumapine, umuhuza, unyuze mu mwobo nizindi nzego.

Ibisobanuro bya PCIe 5.0 ikoresha imiyoboro ifite -36dB attenuation kuri 16 GHz.Umuyoboro wa 16 GHz ugereranya Nyquist inshuro ya 32 GT / s ibimenyetso bya digitale.Kurugero, mugihe ibimenyetso bya PCIe5.0 bitangiye, birashobora kugira ingufu zisanzwe zingana na 800 mV.Ariko, nyuma yo kunyura kumuyoboro wasabwe -36dB, ikintu cyose gisa nijisho rifunguye.Gusa ukoresheje transmitter ishingiye kuringaniza (de-accentuating) hamwe no kuringaniza kwakirwa (guhuza CTLE na DFE) ibimenyetso bya PCIe5.0 byanyura kumuyoboro wa sisitemu kandi bigasobanurwa neza nuwakiriye.Uburebure bw'amaso buteganijwe bwa PCIe 5.0 ni 10mV (nyuma yo kunganya).Ndetse hamwe na transmitter yegeranye-yuzuye neza, kwiyegereza kwinshi kumuyoboro bigabanya amplitude yikimenyetso kugeza aho ubundi bwoko bwibimenyetso byangiritse biterwa no gutekereza hamwe ninzira nyabagendwa bishobora gufungwa kugirango ijisho risubizwe.
