Inkcazo yemiqondiso ye-PCI

Inkcazo yemiqondiso ye-PCI
I-PCI Slot, okanye ukwandiswa kwe-PCI ekwanti, isebenzisa iseti yemigca evumela unxibelelwano nolawulo phakathi kwezixhobo ezinxulumene nebhasi yePCI. Olu phawu lubalulekile ekuqinisekiseni ukuba izixhobo zinokudlulisela idatha kwaye zilawule amazwe abo ngokomgaqo wePCI. Nazi izinto eziphambili zenkcazo yemiqondiso ye-PCI yeSlot:
Imigca ebalulekileyo yomqondiso
I-1. Idilesi / ibhasi yedatha (intengiso [31: 0]):
Lo ngumgca wokuqala wothungelwano kwiBhasi yePCI. I-Coultingd ukuthwala iidilesi zombini (ngexesha leedilesi) kunye nedatha (ngexesha ledatha) phakathi kwesixhobo kunye nenginginya.
2. Isakhelo #:
Iqhutywa sisixhobo senkosi yangoku, isakhelo # sibonisa ukuqala kunye nokufikelela. Ingcaciso yayo iphawula ukuqala kotshintsho, kwaye ukuzingisa kwayo kubonisa ukuba ukuhanjiswa kwedatha kuyaqhubeka. I-De-Acturetion ibonisa ukuphela kwesigaba sokugqibela sedatha.
I-3. I-Irdy # (i-initiator ilungile):
Ibonisa ukuba isixhobo senkosi sikulungele ukuhambisa idatha. Ngexesha lomjikelo ngamnye wewotshi yokudluliselwa kwedatha, ukuba inkosi inokuqhuba idatha ebhasini, iphakamisa irdy #.
I-4. I-Devsel # (isixhobo Khetha):
Ukuqhutywa sisixhobo sekhoboka ekujoliswe kulo, i-Devsel # ichaza ukuba isixhobo sikulungele ukuphendula umsebenzi webhasi. Ukulibaziseka ekucaciseni i-vrincel # ichaza ukuba kuthatha ixesha elingakanani ukuba isixhobo sekhoboka silungiselela ukuphendula kumyalelo webhasi.
5. Yima # (ngokuzithandela):
Umqondiso wokukhetha osetyenziselwa ukwazisa isixhobo senkosi ukuba iyeke ukudluliselwa kwedatha yangoku kwiimeko ezizodwa, njengaxa isixhobo ekujoliswe kuzo singenakuwugqiba ukudluliselwa.
I-6. I-Perr # (Impazamo yeParity):
Iqhutywa sisixhobo sekhoboka ukuba sixele iimpazamo zotyhutywe zifunyenwe ngexesha lokudluliselwa kwedatha.
7. Iserr # (impazamo yenkqubo):
Isetyenziselwa ukunika ingxelo ngeempazamo zenkqubo ezinokubangela iziphumo zentlekele, ezinjengeempazamo zesamente okanye iimpazamo zePagety kwi-parimer kwilandelelwano lomyalelo okhethekileyo.
Imigca yokulawula
I-1. Umyalelo / Byte unika amandla (c / ube [3: 0] #):
I-Commalls yebhasi ngexesha leedilesi zedilesi kunye ne-Byte yenza ukuba imiqondiso ngexesha lezigaba zedatha, ukumisela ukuba yeyiphi i-AD [31: 0] ibhasi yidatha esebenzayo.
2. I-Req # (isicelo sokusebenzisa ibhasi):
Ukuqhutywa sisixhobo esinqwenela ukufumana ulawulo lwebhasi, libonisa isicelo salo.
I-3. GNT # (isibonelelo sokusebenzisa ibhasi):
Ukuqhutywa yi-Arbiter, i-GNT # ibonisa isixhobo esicela ukuba isicelo sayo siyisebenzisile ibhasi.
Eminye imigca
Imiqondiso yokuLawula:
Faka imiqondiso esetyenziselwa ukulamla ibhasi, ukuqinisekisa ukwabiwa ngokufanelekileyo kwezixhobo zebhasi phakathi kwezixhobo ezininzi ezicela ukuFikelela kwangaxeshanye.
Iimpawu eziphazamisayo (i-intsa #, i-intb #, i-Intc #, Intd #):):
Isetyenziswe ngamaziko ekhoboka ukuthumela izicelo eziphazamisayo kumniniyo, zazise kwimisitho ethile okanye utshintsho olukhethekileyo.
Isishwankathelo, iNkcazo yoMqondiso yePCO Slot ibandakanya inkqubo entsonkothileyo yemigca yokudluliselwa kwedatha, ulawulo lwesixhobo, ukunika ingxelo ngebhasi yePCI. Nangona ibhasi ye-PCI iye yanikezelwa ziibhasi zePCIE ephezulu, iPCI Slot kwaye iinkcazo zayo zemiqondiso zihlala zibalulekile kwiinkqubo ezininzi zelifa kunye nezicelo ezithile.
