x86-platvormide arhitektuuris on tekkinud kaks vastastikku t\u00e4iendavat suunda. \u00dche versiooni kohaselt tuleb liikuda integreerimise suunas, kus arvutus- ja juhtimisressursid on \u00fches kristallis.

Peamine erinevus eelneva Intel C610 kiibistiku ees on protsessori ja PCH mikrokiibi perifeeria suhtluse kanali laiendamine, kasutades PCIe-linke koos traditsioonilise DMI-bussiga.<\/p>\n

\nVaatame l\u00e4hemalt Intel Lewisburg'i l\u00f5unaj\u00f5e silda: milliste evolutsiooniliste ja revolutsiooniliste l\u00e4henemiste kaudu on laiendatud tema volitusi suhtluses protsessoritega?<\/p>\n

Evolutsioonilised muutused CPU-PCH suhtluses<\/h2>\n

\nEvolutsioonilise l\u00e4henemise raames on CPU peamine suhtluskanal l\u00f5una sillaga, milleks on DMI (Direct Media Interface) buss, saanud PCIe x4 Gen3 re\u017eiimi toe, mille tulemuslikkus on 8.0 GT\/S. Varem k\u00e4idi Intel C610 PCH puhul CPU ja s\u00fcsteemilogika suhtlus PCIe x4 Gen 2 re\u017eiimis, mille ribalaius oli 5.0 GT\/S.<\/p>\n

\"T\u00e4iendavad
\n
\nIntel C610 ja C620 s\u00fcsteemilogika funktsionaalsuse v\u00f5rdlus<\/em><\/p>\n

Tuleb m\u00e4rkida, et see alams\u00fcsteem on oluliselt konservatiivsem kui CPU sisseehitatud PCIe sadamad, mida tavaliselt kasutatakse GPU ja NVMe hoidlate \u00fchendamiseks, kus on juba pikka aega kasutusel PCIe 3.0 ja on kavandatud \u00fcleminek PCI Express Gen4-le.<\/p>\n

Revolutsioonilised muudatused CPU-PCH suhtluses<\/h2>\n

\nRevolutsiooniliste muudatuste hulka kuulub uute PCIe suhtluskanalite lisamine CPU-PCH, mida nimetatakse t\u00e4iendavateks uplinkideks. F\u00fc\u00fcsiliselt on need kaks PCI Express porti, mis t\u00f6\u00f6tavad PCIe x8 Gen3 ja PCIe x16 Gen3 re\u017eiimides, m\u00f5lema tulemuslikkus on 8.0 GT\/S.<\/p>\n

\"T\u00e4iendavad

\nCPU ja Intel C620 PCH suhtlemiseks kasutatakse 3 bussi: DMI ja kaks PCI Express porti<\/em><\/p>\n

Miks oli vajalik \u00fclevaade olemasolevast Intel C620 kommunikatsioonitopoloogiast? Esiteks, PCH koostises v\u00f5ib olla integreeritud kuni 4x 10GbE v\u00f5rgu kontrollerit RDMA funktsionaalsusega. Teiseks vastutab uue ja kiirema Intel QuickAssist Technology (QAT) kooprotsessorite p\u00f5lvkond v\u00f5rgu liikluse ja salvestuss\u00fcsteemiga suhtlemise kr\u00fcpteerimise eest, pakkudes riistvaralist tuge kompressioonile ja kr\u00fcpteerimisele. Ja l\u00f5puks, \"innovatsioonimootor\" \u2014 Innovatsioonimootor<\/a><\/noindex>, mis on saadaval ainult OEM tootjatele.<\/p>\n

Skaleeritavus ja paindlikkus<\/h2>\n

\nOluline omadus on mitte ainult PCH \u00fchendustopoloogia valik, vaid ka mikrokiibi sisemiste ressursside prioriteetide seadmine juurdep\u00e4\u00e4suks keskprotsessori (protsessorite) kiiretele andmeside kanalitele. Lisaks, spetsiaalses EPO (EndPoint Only Mode) re\u017eiimis toimub PCH \u00fchendamine tavalise PCI Express seadmena, sisaldades 10 GbE ja Intel QAT ressursse. Samuti on klassikaline DMI liides ja mitmed Legacy alams\u00fcsteemid, mis on diagrammil esitatud musta v\u00e4rviga, v\u00e4lja l\u00fclitatud.<\/p>\n

\"T\u00e4iendavad
\n
\nIntel C620 PCH sisemine arhitektuur<\/em><\/p>\n

Teoreetiliselt annab see v\u00f5imaluse s\u00fcsteemis kasutada rohkem kui \u00fchte Intel C620 PCH kiipi, laiendades 10 GbE funktsionaalsust ja Intel QAT vastavalt j\u00f5udluse n\u00f5uetele. Samal ajal saavad Legacy-funktsioonid, mis on vajalikud vaid \u00fches eksemplaris, olla aktiveeritud ainult \u00fchel installitud PCH kiibist.<\/p>\n

Nii et l\u00f5plik s\u00f5na disainis kuulub platvormi arendajale, kes tegutseb tehnoloogiliste ja turunduslike tegurite alusel vastavalt iga konkreetse toote positsioneerimisele.
