Okwu mmalite PCIe 6.0

Òtù PCI-SIG ekwupụtala mwepụta gọọmentị nke ọkọlọtọ PCIe 6.0 nkọwapụta v1.0, na-ekwupụta mmecha.

N'ịga n'ihu mgbakọ ahụ, ọsọ bandwidth na-aga n'ihu na okpukpu abụọ, ruo 128GB / s (unidirectional) na x16, na ebe ọ bụ na nkà na ụzụ PCIe na-enye ohere ịnweta data bidirectional zuru ezu, ngụkọta ụzọ abụọ bụ 256GB / s.Dị ka atụmatụ ahụ si dị, a ga-enwe ihe atụ azụmahịa 12 ruo 18 ọnwa mgbe e bipụtachara ọkọlọtọ, nke bụ ihe dị ka 2023, kwesịrị ibu ụzọ na-adị na ikpo okwu nkesa.PCIe 6.0 ga-abịa na njedebe nke afọ na mbụ, yana bandwit nke 256GB / s.

PCIe 6.0 gbanwere na PAM4 pulse AM signaling, 1B-1B codeing, otu mgbaama nwere ike ịbụ koodu ntinye anọ (00/01/10/11), okpukpu abụọ nke gara aga, na-enye ohere ruo ugboro 30GHz.Agbanyeghị, n'ihi na akara PAM4 na-emebi emebi karịa NRZ, ejiri FEC na-ebugharị usoro mgbazi njehie iji dozie njehie mgbaàmà na njikọ ahụ wee hụ na data ziri ezi.
