Kua pānuitia e te Whakahaere PCI-SIG te tukunga mana o te paerewa whakatakotoranga PCIe 6.0 v1.0, me te kī kua oti.
Hei te haere tonu o te tikanga, ka piki haere tonu te tere o te whānui o te hononga, tae atu ki te 128GB/s (kotahi te ahunga) i te x16, ā, nā te mea ka taea e te hangarau PCIe te rere raraunga takirua-katoa, ko te tapeke o te whakawhiti raraunga e rua-ara he 256GB/s. E ai ki te mahere, ka puta ngā tauira arumoni 12 ki te 18 marama i muri i te whakaputanga o te paerewa, arā, i te tau 2023 pea, me puta tuatahi ki te tūāpapa tūmau. Ka tae mai te PCIe 6.0 i te mutunga o te tau i te wā tōmua, me te whānui o te hononga o te 256GB/s.
Hoki atu ki te hangarau tonu, e kiia ana ko te PCIe 6.0 te panonitanga nui rawa atu i roto i te hītori tata ki te 20 tau o te PCIe. Ki te pono, he whakarerekētanga iti noa iho te PCIe 4.0/5.0 o te 3.0, pērā i te whakawaehere 128b/130b i runga i te NRZ (Non-Return-to-Zero).
Kua huri te PCIe 6.0 ki te tohu PAM4 pulse AM, te waehere 1B-1B, ka taea e te tohu kotahi te whakakōwae i ngā āhua e whā (00/01/10/11), te rua o te o mua, ka taea te auau tae atu ki te 30GHz. Heoi, nā te mea he pakarukaru ake te tohu PAM4 i te NRZ, kua rite ki te tikanga whakatika hapa whakamua FEC hei whakatika i ngā hapa tohu i roto i te hononga me te whakarite i te pono o ngā raraunga.
Haunga te PAM4 me te FEC, ko te hangarau nui whakamutunga i roto i te PCIe 6.0 ko te whakamahinga o te FLIT (Flow Control Unit) i te taumata arorau. Inaa, ehara te PAM4, te FLIT i te hangarau hou, kua roa te whakamahinga o te Ethernet tere-rahi 200G+, kāore i taea e te PAM4 te whakatairanga nui i te take he nui rawa te utu o te paparanga tinana.
Hei tāpiri, kei te hototahi tonu te PCIe 6.0 ki ngā pūnaha whakamuri.
Kei te haere tonu te PCIe 6.0 ki te whakaneke rua i te whānui o te I/O ki te 64GT/s e ai ki te tikanga tuku iho, e pā ana ki te whānui o te PCIe 6.0X1 kotahi-ara o te 8GB/s, te whānui o te PCIe 6.0×16 kotahi-ara o te 128GB/s, me te whānui o te pcie 6.0×16 rua-ara o te 256GB/s. Ko ngā SSD PCIe 4.0 x4, e whakamahia whānuitia ana i ēnei rā, me PCIe 6.0 x1 anake hei mahi i tēnei.
Ka haere tonu te PCIe 6.0 i te whakakōwae 128b/130b i whakaurua mai i te wā o PCIe 3.0. Haunga te CRC taketake, he mea whakamere ki te mōhio kei te tautoko hoki te kawa hongere hou i te whakakōwae PAM-4 e whakamahia ana i roto i te Ethernet me te GDDR6x, hei whakakapi i te PCIe 5.0 NRZ. Ka taea te tākai i ngā raraunga maha atu i roto i te hongere kotahi i roto i te wā kotahi, me te tikanga whakatika hapa raraunga iti-roa e mōhiotia ana ko te whakatika hapa whakamua (FEC) hei whakahaere me te pono i te whakanui ake i te whānui o te hononga.
He maha ngā tāngata e pātai ana, kāore i te whakamahia te whānui o te PCIe 3.0, he aha te whakamahinga o te PCIe 6.0? Nā te pikinga ake o ngā tono e hiahia ana ki ngā raraunga, tae atu ki te matauranga horihori, ko ngā hongere IO me ngā tere tuku tere kei te piki haere te hiahia o ngā kiritaki i te mākete ngaio, ā, ka taea e te whānui teitei o te hangarau PCIe 6.0 te wetewete katoa i te mahi o ngā hua e hiahia ana ki te whānui teitei o te IO tae atu ki ngā whakatere, te ako mīhini me ngā tono HPC. Ko te tumanako hoki a PCI-SIG kia whai hua mai i te tipu haere o te umanga motuka, he wāhi wera mō ngā semiconductors, ā, kua whakatū te PCI-Special Interest Group i tētahi rōpū mahi Hangarau PCIe hou hei arotahi ki te whakanui ake i te tangohanga o te hangarau PCIe i roto i te umanga motuka, i te mea e kitea ana te pikinga ake o te hiahia o te pūnaha mō te whānui. Heoi, i te mea ka taea te hono i te tukatuka iti, te GPU, te taputapu IO me te rokiroki raraunga ki te hongere raraunga, PC ki te whiwhi tautoko o te atanga PCIe 6.0, me tino tupato ngā kaihanga papahoahoa ki te whakarite i te taura ka taea te whakahaere i ngā tohu tere-tiketike, me te whakarite hoki i ngā kaihanga chipset. Kāore te kaikorero a Intel i pai ki te kī āhea ka tāpirihia te tautoko PCIe 6.0 ki ngā taputapu, engari i whakaū ka tautokona e te kaihoko a Alder Lake me te taha tūmau a Sapphire Rapids me Ponte Vecchio te PCIe 5.0. Kāore hoki a NVIDIA i pai ki te kī āhea ka whakaurua mai te PCIe 6.0. Heoi, kua tautokona kētia e te BlueField-3 Dpus mō ngā pokapū raraunga te PCIe 5.0; Ko te PCIe Spec anake e tohu ana i ngā mahi, te mahi, me ngā tawhā e tika ana kia whakatinanahia ki te paparanga ā-tinana, engari kāore e tohu me pēhea te whakatinana i ēnei. Arā, ka taea e ngā kaihanga te hoahoa i te hanganga paparanga ā-tinana o te PCIe kia rite ki ā rātou ake hiahia me ngā āhuatanga tūturu kia pai ai te mahi! Ka taea e ngā kaihanga taura te tākaro i te wāhi nui ake!
