Intshayelelo PCIe 6.0

Umbutho we-PCI-SIG ubhengeze ukukhutshwa ngokusemthethweni komgangatho we-PCIe 6.0 we-v1.0, ukuvakalisa ukugqitywa.

Ukuqhubela phambili ingqungquthela, isantya se-bandwidth siyaqhubeka siphindwe kabini, ukuya kuthi ga kwi-128GB / s (unidirectional) kwi-x16, kwaye ekubeni iteknoloji ye-PCIe ivumela ukuhamba kwedatha ye-bidirectional epheleleyo, i-256GB / s.Ngokutsho kwesicwangciso, kuya kuba nemizekelo yorhwebo kwiinyanga ezili-12 ukuya kwii-18 emva kokupapashwa komgangatho, malunga ne-2023, kufuneka ibe kwi-platform yomncedisi kuqala.I-PCIe 6.0 iya kuza ekupheleni konyaka kwasekuqaleni, kunye ne-bandwidth ye-256GB / s.

Ukubuyela kwitekhnoloji ngokwayo, i-PCIe 6.0 ithathwa njengolona tshintsho lukhulu kwimbali ye-PCIe ephantse ibe yi-20 yeminyaka.Ukuthetha ngokunyanisekileyo, i-PCIe 4.0/5.0 yinto encinci yokuguqulwa kwe-3.0, njenge-encoding ye-128b / 130b esekelwe kwi-NRZ (i-Non-Return-to-Zero).

I-PCIe 6.0 itshintshele kwi-PAM4 i-pulse AM, i-coding ye-1B-1B, isignali enye ingaba ne-encoding emine (00/01/10/11) ithi, iphindwe kabini yangaphambili, ivumela ukuya kuthi ga kwi-30GHz.Nangona kunjalo, ngenxa yokuba isignali ye-PAM4 ibuthathaka ngakumbi kune-NRZ, ixhotyiswe nge-FEC phambili yokulungiswa kwempazamo ukulungisa iimpazamo zesignali kwikhonkco kunye nokuqinisekisa imfezeko yedatha.

Ukongeza kwi-PAM4 kunye ne-FEC, iteknoloji yokugqibela enkulu kwi-PCIe 6.0 kukusetyenziswa kwe-FLIT (i-Flow Control Unit) encoding kwinqanaba elinengqiqo.Enyanisweni, i-PAM4, i-FLIT ayiyona iteknoloji entsha, kwi-200G + i-ultra-high-speed Ethernet sele isetyenziswe ixesha elide, apho i-PAM4 yahluleka ukunyuswa okukhulu kwesizathu kukuba indleko yomgangatho womzimba iphezulu kakhulu.

Ukongeza, i-PCIe 6.0 ihlala ngasemva iyahambelana.

I-PCIe 6.0 iyaqhubeka nokuphindaphinda i-I / O i-bandwidth kwi-64GT / s ngokwesithethe, esetyenziswe kwi-PCIe yangempela ye-6.0X1 i-bandwidth ye-8GB / s, i-PCIe 6.0 × 16 i-unidirectional bandwidth ye-128GB / s, kunye ne-pcie 6.0 × I-16 ye-bidirectional bandwidth ye-256GB / s.I-PCIe 4.0 x4 SSDS, esetyenziswa ngokubanzi namhlanje, iya kufuna kuphela i-PCIe 6.0 x1 ukuyenza.

I-PCIe 6.0 iya kuqhubeka ne-128b/130b encoding eqaliswe kwixesha le-PCIe 3.0.Ukongeza kwi-CRC yoqobo, kunomdla ukuqaphela ukuba iprotocol entsha yesitishi ikwaxhasa i-PAM-4 encoding esetyenziswa kwi-Ethernet kunye ne-GDDR6x, ithatha indawo yePCIe 5.0 NRZ.Idatha eyongezelelweyo inokupakishwa kwitshaneli enye ngexesha elifanayo, kunye nendlela yokulungiswa kwempazamo yedatha ephantsi eyaziwa ngokuba yi-forward error correction (FEC) ukwenza ukunyuka kwe-bandwidth yenzeke kwaye inokwethenjelwa.

Abantu abaninzi banokubuza, i-PCIe 3.0 bandwidth ayisoloko isetyenziswa, iPCIe 6.0 yintoni esetyenziswayo?Ngenxa yokwanda kwezicelo ezilambele idatha, kubandakanya nobukrelekrele bokwenziwa, iziteshi ze-IO ezinamazinga othumelo olukhawulezayo ziya zisiba yimfuno yabathengi kwimarike yobuchwephesha, kunye ne-bandwidth ephezulu ye-PCIe 6.0 yetekhnoloji inokuvula ngokupheleleyo ukusebenza kweemveliso ezifuna i-IO ephezulu. i-bandwidth equka i-accelerators, ukufunda ngomatshini kunye nezicelo ze-HPC.I-PCI-SIG inethemba lokuxhamla kwishishini elikhulayo leemoto, eliyindawo eshushu ye-semiconductors, kunye neqela le-PCI-Special Interest Group lenze iqela elitsha lokusebenza le-PCIe Technology ukugxila kwindlela yokwandisa ukwamkelwa kweteknoloji ye-PCIe kwi-automotive. kushishino, njengoko i-ikhosistim yokwanda kwemfuno ye-bandwidth ibonakala.Nangona kunjalo, njengoko i-microprocessor, i-GPU, isixhobo se-IO kunye nokugcinwa kwedatha kunokudityaniswa kwitshaneli yedatha, iPC ukufumana inkxaso ye-PCIe 6.0 interface, abavelisi bebhodi ye-motherboard kufuneka balumke ngakumbi ukulungiselela ikhebula elinokuphatha imiqondiso enesantya esiphezulu, kunye nabavelisi be-chipset nabo kufuneka benze amalungiselelo afanelekileyo.Isithethi se-Intel sinqabile ukutsho ukuba inkxaso ye-PCIe 6.0 iya kongezwa nini kwizixhobo, kodwa yaqinisekisa ukuba umthengi we-Alder Lake kunye necala leseva iSapphire Rapids kunye nePonte Vecchio ziya kuxhasa iPCIe 5.0.I-NVIDIA ikwalile ukutsho ukuba iPCIe 6.0 iya kwaziswa nini.Nangona kunjalo, iBlueField-3 Dpus yamaziko edatha sele ixhasa i-PCIe 5.0;I-PCIe Spec ichaza kuphela imisebenzi, ukusebenza, kunye neeparamitha ekufuneka ziphunyezwe kumaleko womzimba, kodwa ayicacisi indlela yokuphumeza ezi.Ngamanye amazwi, abavelisi banokuyila ukwakheka kwe-PCIe ngokweemfuno zabo kunye neemeko zokwenyani zokuqinisekisa ukusebenza!Abavelisi beentambo banokudlala indawo eninzi!
