Nhanganyaya PCIe 6.0

Iyo PCI-SIG Organisation yakazivisa kuburitswa zviri pamutemo kwePCIe 6.0 yakatarwa standard v1.0, ichizivisa kupera.

Kuenderera mberi negungano, iyo bandwidth yekumhanyisa inoramba ichipeta, kusvika ku128GB/s(unidirectional) pax16, uye sezvo tekinoroji yePCIe ichibvumira kuyerera kwedata kuzere-duplex, iyo nzira mbiri-yakazara ndeye 256GB/s.Zvinoenderana nehurongwa, pachava nemienzaniso yekutengeserana 12 kusvika 18 mwedzi mushure mekuburitswa kweiyo chiyero, iyo inenge 2023, inofanira kunge iri pachikuva che server kutanga.PCIe 6.0 ichauya mukupera kwegore pakutanga, ine bandwidth ye256GB/s.

Kudzokera kune tekinoroji pachayo, PCIe 6.0 inoonekwa seyakanyanya shanduko muPCIe angangoita makore makumi maviri nhoroondo.Kutaura chokwadi, PCIe 4.0/5.0 igadziriso diki ye3.0, senge 128b/130b encoding yakavakirwa paNRZ (Non-Return-to-Zero).

PCIe 6.0 yakachinjirwa kuPAM4 pulse AM siginecha, 1B-1B coding, chiratidzo chimwe chete chinogona kuita ina encoding (00/01/10/11) inoti, yakapetwa kaviri yapfuura, ichibvumira kusvika ku30GHz frequency.Nekudaro, nekuti PAM4 siginecha haina kusimba kupfuura NRZ, yakashongedzerwa neFEC yekumberi yekururamisa nzira yekururamisa zvikanganiso zvechiratidzo mune chinongedzo uye kuve nechokwadi chekuvimbika kwedata.

Pamusoro pePAM4 neFEC, tekinoroji yakakura yekupedzisira muPCIe 6.0 ndeye kushandiswa kweFLIT (Flow Control Unit) encoding padanho rinonzwisisika.Kutaura zvazviri, PAM4, FLIT haisi teknolojia itsva, mu 200G + ultra-high-speed Ethernet yakashandiswa kwenguva refu, iyo PAM4 yakakundikana kukurudzirwa kukuru kwechikonzero ndechokuti mutengo wemuviri wepamusoro wakanyanya kukwirira.

Uye zvakare, PCIe 6.0 inoramba iri kumashure inoenderana.

PCIe 6.0 inoramba ichiwedzera kaviri I / O bandwidth kusvika 64GT / s maererano netsika, iyo inoshandiswa kune chaiyo PCIe 6.0X1 unidirectional bandwidth ye8GB / s, PCIe 6.0 × 16 unidirectional bandwidth ye128GB / s, uye pcie 6.0 × 16 bidirectional bandwidth ye256GB/s.PCIe 4.0 x4 SSDS, iyo inoshandiswa zvakanyanya nhasi, inongoda PCIe 6.0 x1 kuti iite.

PCIe 6.0 ichaenderera mberi ne128b/130b encoding yakaunzwa munguva yePCIe 3.0.Pamusoro peiyo CRC yepakutanga, zvinonakidza kuziva kuti itsva chiteshi protocol inotsigirawo PAM-4 encoding inoshandiswa muEthernet uye GDDR6x, ichitsiva PCIe 5.0 NRZ.Mamwe data anogona kutakurwa mune imwe chiteshi mune imwe nguva yenguva, pamwe neakaderera-latency data kukanganisa kururamisa nzira inozivikanwa sekumberi kukanganisa kururamisa (FEC) kuita kuti kuwedzera bandwidth kugoneke uye kwakavimbika.

Vanhu vazhinji vanogona kubvunza, PCIe 3.0 bandwidth kazhinji haishandiswe kumusoro, PCIe 6.0 ndiyo inoshandiswa?Nekuda kwekuwedzera kwemaapplication ane nzara yedata, kusanganisira hungwaru hwekunyepedzera, nzira dzeIO dzine kukurumidza kutapurirana mitengo dziri kuwedzera kuve kudiwa kwevatengi mumusika wehunyanzvi, uye yakakwirira bandwidth yePCIe 6.0 tekinoroji inogona kuvhura zvizere mashandiro ezvigadzirwa zvinoda yakakwira IO. bandwidth inosanganisira accelerators, kudzidza muchina uye HPC application.PCI-SIG inotarisirawo kubatsirwa kubva muindasitiri yemotokari iri kukura, inova nzvimbo inopisa yemasemiconductors, uye PCI-Special Interest Group yakagadzira boka idzva rekushanda rePCIe Technology kuti ritarise nzira yekuwedzera kutorwa kwePCIe tekinoroji mumotokari. indasitiri, sezvo ecosystem yakawedzera kudiwa kwebandwidth inoonekwa.Nekudaro, seiyo microprocessor, GPU, IO mudziyo uye kuchengetedza data kunogona kubatanidzwa kune data chiteshi, PC kuwana rutsigiro rwePCIe 6.0 interface, vagadziri vebhodhi reamai vanofanirwa kungwarisa kuronga tambo inokwanisa kubata masaini ekumhanya, uye vanogadzira chipset vanofanirwawo kuita gadziriro dzakakodzera.Mutauriri weIntel akaramba kutaura kuti PCIe 6.0 rutsigiro ichawedzerwa riini kumidziyo, asi akasimbisa kuti mutengi Alder Lake uye server side Sapphire Rapids uye Ponte Vecchio ichatsigira PCIe 5.0.NVIDIA yarambawo kutaura kuti PCIe 6.0 ichaunzwa rinhi.Nekudaro, BlueField-3 Dpus yedata data yatove inotsigira PCIe 5.0;Iyo PCIe Spec inongo tsanangura mabasa, kuita, uye ma paramita anoda kuitwa pachikamu chemuviri, asi haataure maitiro ekuita izvi.Mune mamwe mazwi, vagadziri vanogona kugadzira iyo yemuviri layer yePCIe zvinoenderana nezvavanoda uye chaiwo mamiriro ekuona kushanda!Vagadziri vetambo vanogona kutamba yakawanda nzvimbo!
