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 × i-16 i-unidirectional 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, kubandakanywa nobukrelekrele bokwenziwa, amajelo e-IO anamazinga othumelo olukhawulezayo ayanda abe yimfuno yabathengi kwimarike yobuchwephesha, kwaye i-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 kushishino lweemoto olukhulayo, oluyindawo eshushu ye-semiconductors, kunye neqela le-PCI-Special Interest Group liye laqulunqa iqela elitsha elisebenzayo 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 ikhankanya kuphela imisebenzi, ukusebenza, kunye neeparamitha ekufuneka ziphunyezwe kumaleko womzimba, kodwa ayicacisi indlela yokuphumeza ezi.Ngamanye amazwi, abavelisi banokuyila ubume bomzimba bePCIe ngokweemfuno zabo kunye neemeko zokwenyani zokuqinisekisa ukusebenza!Abavelisi beentambo banokudlala indawo eninzi!
