Pakumanga kwa nsanja za x86, njira ziwiri zatulukira zomwe zimagwirizana. Malinga ndi mtundu wina, tikuyenera kusunthira kukuphatikizira zinthu zamakompyuta ndikuwongolera kukhala chip chimodzi. Njira yachiwiri imalimbikitsa kugawa kwa maudindo: purosesa ili ndi basi yogwira ntchito kwambiri yomwe imapanga chilengedwe chozungulira. Zimapanga maziko a Intel C620 system logic topology pamapulatifomu apamwamba.
Kusiyana kwakukulu kuchokera ku chipangizo cham'mbuyo cha Intel C610 ndikukulitsa njira yolumikizirana pakati pa purosesa ndi zotumphukira zomwe zikuphatikizidwa mu chipangizo cha PCH pogwiritsa ntchito maulalo a PCIe limodzi ndi basi yachikhalidwe ya DMI.
Tiyeni tiwone mwatsatanetsatane za zatsopano za Intel Lewisburg kum'mwera mlatho: ndi njira ziti zachisinthiko ndi zosinthika zomwe zakulitsa mphamvu zake polumikizana ndi mapurosesa?
Kusintha kwachisinthiko mu kulumikizana kwa CPU-PCH
Monga gawo lachisinthiko, njira yayikulu yolumikizirana pakati pa CPU ndi mlatho wakumwera, womwe ndi basi ya DMI (Direct Media Interface), idalandira chithandizo cha PCIe x4 Gen3 mode ndikuchita kwa 8.0 GT/S. M'mbuyomu, mu Intel C610 PCH, kulumikizana pakati pa purosesa ndi malingaliro adongosolo kunkachitika mu PCIe x4 Gen 2 mode pa 5.0 GT/S bandwidth.
Kuyerekeza kwa magwiridwe antchito a Intel C610 ndi C620
Zindikirani kuti kachitidwe kameneka kamakhala kosamala kwambiri kuposa madoko omangidwa a PCIe a purosesa, omwe nthawi zambiri amagwiritsidwa ntchito kulumikiza ma GPU ndi ma drive a NVMe, pomwe PCIe 3.0 yakhala ikugwiritsidwa ntchito kwa nthawi yayitali ndipo kusintha kwa PCI Express Gen4 kukukonzekera.
Kusintha kwakusintha kwa kulumikizana kwa CPU-PCH
Kusintha kwakusintha kumaphatikizapo kuwonjezera njira zatsopano zoyankhulirana za PCIe CPU-PCH, zotchedwa Zowonjezera Uplink. Mwathupi, awa ndi madoko awiri a PCI Express omwe akugwira ntchito mu PCIe x8 Gen3 ndi PCIe x16 Gen3 modes, onse 8.0 GT/S.
Pakuyanjana pakati pa CPU ndi Intel C620 PCH, mabasi atatu amagwiritsidwa ntchito: DMI ndi madoko awiri a PCI Express.
Chifukwa chiyani kunali kofunikira kuwunikiranso njira yolumikizirana yomwe ilipo ndi Intel C620? Choyamba, mpaka olamulira a 4x 10GbE omwe ali ndi machitidwe a RDMA akhoza kuphatikizidwa mu PCH. Kachiwiri, m'badwo watsopano komanso wachangu wa Intel QuickAssist Technology (QAT) ma coprocessors, omwe amapereka chithandizo cha Hardware pakukakamiza ndi kubisa, ali ndi udindo wosunga kuchuluka kwa magalimoto pamaneti ndikusinthana ndi makina osungira. Ndipo potsiriza, "injini ya innovation" - , yomwe ipezeka kwa ma OEM okha.
Scalability ndi kusinthasintha
Chinthu chofunika kwambiri ndi kuthekera kosankha osati kokha PCH kugwirizana topology, komanso zinthu zofunika kwambiri za mkati mwa chip kuti apeze njira zoyankhulirana zothamanga kwambiri ndi purosesa yapakati (mapurosesa). Kuphatikiza apo, mu EPO yapadera (EndPoint Only Mode), kulumikizana kwa PCH kumachitika ngati chipangizo chokhazikika cha PCI Express chokhala ndi 10 GbE zothandizira ndi Intel QAT. Nthawi yomweyo, mawonekedwe apamwamba a DMI, komanso magawo angapo a Legacy, omwe akuwonetsedwa mukuda pachithunzichi, amayimitsidwa.
Zomangamanga zamkati za Intel C620 PCH chip
Mwachidziwitso, izi zimapangitsa kuti zitheke kugwiritsa ntchito chipangizo chimodzi cha Intel C620 PCH mu dongosolo, kukweza 10 GbE ndi Intel QAT magwiridwe antchito kuti akwaniritse zofunikira. Nthawi yomweyo, ntchito za Legacy zomwe zimafunikira mukope limodzi zitha kuthandizidwa pa imodzi mwa tchipisi ta PCH.
Chifukwa chake, mawu omaliza pamapangidwe adzakhala a wopanga nsanja, azichita pazifukwa zaukadaulo komanso zamalonda molingana ndi kuyika kwa chinthu chilichonse.
