x86-platvormide arhitektuuris on tekkinud kaks suunda, mis \u00fcksteist t\u00e4iendavad. \u00dche versiooni kohaselt tuleb liikuda suunas, kus arvutus- ja juhtimisressursid on integreeritud \u00fchte kristalli. Teine l\u00e4henemine pooldab \u00fclesannete jaotamist: protsessor varustatakse v\u00f5imsa bussiga, mis loob perifeersete skalaarset \u00f6kos\u00fcsteemi. See on aluseks Intel C620 s\u00fcsteemilogika topoloogiale k\u00f5rgetasemelistele platvormidele.<\/a><\/noindex><\/p>\n

P\u00f5him\u00f5tteline erinevus eelneva Intel C610 kiibistiku puhul seisneb protsessori ja PCH mikrokiibi perifeeria vahelise suhtluse kanali laiendamises, kasutades PCIe-linke koos traditsioonilise DMI-bussiga.<\/p>\n

\"Additional
\n
\nVaadakem l\u00e4hemalt Intel Lewisburgi l\u00f5una silla uuendusi: milliseid evolutsioonilisi ja revolutsioonilisi l\u00e4henemisi on laiendatud selle volitustes suhtlemisel protsessoritega?<\/p>\n

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

\nEvolutsioonilise l\u00e4henemise raames sai peamine suhtluskanal CPU ja l\u00f5una silla vahel, milleks on DMI buss (Direct Media Interface), PCIe x4 Gen3 re\u017eiimi toetuse ja 8.0 GT\/S j\u00f5udluse. Varem, Intel C610 PCH puhul viidi protsessori ja s\u00fcsteemilogika suhtlus l\u00e4bi PCIe x4 Gen 2 re\u017eiimis, mille ribalaius oli 5.0 GT\/S.<\/p>\n

\"Additional
\n
\nIntel C610 ja C620 s\u00fcsteemilogika funktsionaalsuse v\u00f5rdlemine<\/em><\/p>\n

Tuleb m\u00e4rkida, et see alams\u00fcsteem on oluliselt konservatiivsem kui protsessori sisse ehitatud PCIe-porte, mida tavaliselt kasutatakse GPU ja NVMe seadmete \u00fchendamiseks, kus juba ammu on kasutusele v\u00f5etud PCIe 3.0 ning plaanitakse \u00fcleminekut PCI Express Gen4-le.<\/p>\n

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

\nRevolutsiooniliste muudatuste hulka kuulub uute PCIe suhtluskanalite lisamine CPU-PCH vahel, mida nimetatakse t\u00e4iendavateks t\u00f5stikuteks. F\u00fc\u00fcsiliselt on need kaks PCI Express porti, mis t\u00f6\u00f6tavad PCIe x8 Gen3 ja PCIe x16 Gen3 re\u017eiimides, m\u00f5lemad - 8.0 GT\/S.<\/p>\n

\"Additional
\n
\nCPU ja Intel C620 PCH vaheliseks suhtlemiseks kasutatakse 3 bussi: DMI ja kahte PCI Express porti.<\/em><\/p>\n

Miks oli vajalik olemasoleva suhtlusstruktuuri \u00fclevaatamine Intel C620-ga? Esiteks, PCH koosseisus v\u00f5ib olla integreeritud kuni 4 10GbE v\u00f5rgu kontrollerit, millel on RDMA funktsionaalsus. Teiseks, v\u00f5rgu liikluse ja salvestuss\u00fcsteemiga suhtluse kr\u00fcptimise eest vastutab uus ja kiirem p\u00f5lvkond Intel QuickAssist Technology (QAT) kooprotsessoreid, mis pakuvad riistvara tuge kompressioonile ja kr\u00fcptimisele. Ja l\u00f5puks - \"uuenduste mootor\" - Innovation Engine<\/a><\/noindex>, mis on saadaval ainult OEM-tootjatele.<\/p>\n

Skaleeritavus ja paindlikkus<\/h2>\n

\nOluline omadus on mitte ainult PCH-\u00fchenduse topoloogia valiku, vaid ka mikrokiibi sisemiste ressursi prioriteetide valik, v\u00f5imalus p\u00e4\u00e4seda kiiresti keskprotsessori (protsessorite) sidekanalitele. Lisaks, spetsiaalses EPO (EndPoint Only Mode) re\u017eiimis, toimub PCH-\u00fchendus tavalise PCI Express seadmena, mis sisaldab 10 GbE ja Intel QAT ressursse. Selle tulemusena on klassikaline DMI liides ning mitmed Legacy-alas\u00fcsteemid, mis on diagrammil mustaga kujutatud, v\u00e4lja l\u00fclitatud.<\/p>\n

\"Additional
\n
\nIntel C620 PCH mikrokiibi sisemine arhitektuur<\/em><\/p>\n

Teoreetiliselt annab see s\u00fcsteemis kasutada rohkem kui \u00fchte Intel C620 PCH mikrokiipi, skaleerides 10 GbE ja Intel QAT funktsionaalsust vastavalt j\u00f5udlusn\u00f5uetele. Samal ajal v\u00f5ivad Legacy-funktsioonid, mis on vajalikud vaid \u00fches eksemplaris, olla lubatud ainult \u00fches paigaldatud PCH mikrokiibis.<\/p>\n

Nii et viimased s\u00f5nad disainis kuuluvad platvormi arendajale, kes tegutseb tehnoloogiliste ja turunduslike tegurite alusel vastavalt iga konkreetse toote positsioneerimisele.
