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.

Laa azụ na teknụzụ n'onwe ya, a na-ewere PCIe 6.0 dị ka mgbanwe kachasị ukwuu na akụkọ ihe mere eme nke PCIe fọrọ nke nta ka ọ bụrụ afọ 20. Iji kwuo eziokwu, PCIe 4.0/5.0 bụ obere mgbanwe nke 3.0, dị ka ntinye 128b/130b dabere na NRZ (Na-alaghachighị-na-efu).

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.

Na mgbakwunye na PAM4 na FEC, teknụzụ ikpeazụ ikpeazụ na PCIe 6.0 bụ iji FLIT (Flow Control Unit) na-edobe na ọkwa ezi uche dị na ya. N'ezie, PAM4, FLIT abụghị nkà na ụzụ ọhụrụ, na 200G + ultra-high-speed Ethernet ka etinyere ya ogologo oge, nke PAM4 na-emezughị nnukwu nkwalite nke ihe kpatara ya bụ na ụgwọ oyi akwa anụ ahụ dị oke elu.

Na mgbakwunye, PCIe 6.0 ka na-adakọ azụ azụ.

PCIe 6.0 na-aga n'ihu na-eme ka bandwidth I / O okpukpu abụọ gaa na 64GT / s dị ka omenala si dị, nke a na-etinye na bandwidth PCIe 6.0X1 unidirectional nke 8GB / s, PCIe 6.0 × 16 bandwidth unidirectional nke 128GB / s, na pcie 6.0 × 16 bidirectional bandwidth / .5. PCIe 4.0 x4 SSDS, nke a na-ejikarị taa, ga-achọ naanị PCIe 6.0 x1 ime ya.

PCIe 6.0 ga-aga n'ihu na ntinye koodu 128b/130b ewepụtara na oge PCIe 3.0. Na mgbakwunye na CRC mbụ, ọ bụ ihe na-adọrọ mmasị ịmara na usoro ọwa ọhụrụ ahụ na-akwadokwa PAM-4 koodu ejiri na Ethernet na GDDR6x, dochie PCIe 5.0 NRZ. Enwere ike ịkwakọba data ndị ọzọ n'otu ọwa n'otu oge ahụ, yana usoro mgbazi njehie data dị ala nke a maara dị ka mmezi njehie na-aga n'ihu (FEC) iji mee ka ịba ụba bandwidth kwe omume na ntụkwasị obi.

Ọtụtụ ndị mmadụ nwere ike ịjụ, PCIe 3.0 bandwit anaghị ejikarị eme ihe, PCIe 6.0 bụ ihe ọ bụ?
