Iinkcazo zesignali ye-PCI SLOT

Iinkcazo zesignali ye-PCI SLOT
I-PCI SLOT, okanye i-PCI expansion slot, isebenzisa iseti yemigca yesignali evumela unxibelelwano kunye nolawulo phakathi kwezixhobo eziqhagamshelwe kwibhasi ye-PCI. Ezi signali zibalulekile ekuqinisekiseni ukuba izixhobo zinokudlulisela idatha kwaye zilawule imeko yazo ngokweprotocol ye-PCI. Nazi iinkalo eziphambili zeenkcazo zesignali ye-PCI SLOT:
Imigca yeSignali ebalulekileyo
1. Ibhasi yeDilesi/yeDatha (AD[31:0]):
Lo ngumgca ophambili wokuhambisa idatha kwibhasi ye-PCI. Udityaniswe ukuze uthwale zombini iidilesi (ngexesha leedilesi) kunye nedatha (ngexesha leedatha) phakathi kwesixhobo kunye nomphathi.
2. IFRAME#:
Iqhutywa sisixhobo esiphambili sangoku, i-FRAME# ibonisa ukuqala kunye nobude bokufikelela. Ukuqinisekiswa kwayo kubonisa ukuqala kokudluliselwa, kwaye ukuqhubeka kwayo kubonisa ukuba ukudluliselwa kwedatha kuyaqhubeka. Ukuyeka ukuqinisekiswa kubonisa ukuphela kwesigaba sokugqibela sedatha.
3. IRDY# (Ukulungele ukuqalisa):
Ibonisa ukuba isixhobo esiyintloko sikulungele ukudlulisa idatha. Ngexesha lomjikelo ngamnye wewotshi yokudlulisa idatha, ukuba i-master inokuqhuba idatha ebhasini, ithi IRDY#.
4. I-DEVSEL# (Ukukhetha isixhobo):
Iqhutywa sisixhobo sekhoboka esijoliswe kuso, i-DEVSEL# ibonisa ukuba isixhobo sikulungele ukuphendula ekusebenzeni kwebhasi. Ukulibaziseka ekuqinisekiseni i-DEVSEL# kuchazwa ukuba kuthatha ixesha elingakanani isixhobo sekhoboka ukulungiselela ukuphendula kumyalelo webhasi.
5. YIMA# (Ukhetho):
Isignali yokuzikhethela esetyenziselwa ukwazisa isixhobo esiphambili ukuba siyeke ukudluliselwa kwedatha yangoku kwiimeko ezikhethekileyo, njengaxa isixhobo ekujoliswe kuso singakwazi ukugqiba ukudluliselwa.
6. I-PERR# (Impazamo yokulingana):
Iqhutywa sisixhobo sekhoboka ukuxela iimpazamo zokulingana ezifunyenweyo ngexesha lokudluliselwa kwedatha.
7. I-SERR# (Impazamo yeNkqubo):
Isetyenziselwa ukuxela iimpazamo kwinqanaba lenkqubo ezinokubangela iziphumo ezibi kakhulu, ezifana neempazamo ze-parity okanye iimpazamo ze-parity kulandelelwano olukhethekileyo lomyalelo.
Imigca yeSignali yoLawulo
1. Umyalelo/Ibhayithi Yenza i-Multiplex ibe lula (C/BE[3:0]#):
Ithwala imiyalelo yebhasi ngexesha leedilesi kwaye i-byte ivumela imiqondiso ngexesha leedatha, imisela ukuba zeziphi ii-byte kwibhasi ye-AD[31:0] eziyidatha esebenzayo.
2. I-REQ# (Isicelo sokusebenzisa iBhasi):
Iqhutywa sisixhobo esifuna ukulawula ibhasi, sibonakalisa isicelo sayo kumlamli.
3. I-GNT# (Imvume yokusebenzisa ibhasi):
Iqhutywa ngumlamli, i-GNT# ibonisa kwisixhobo esicelayo ukuba isicelo sayo sokusebenzisa ibhasi sivunyiwe.
Eminye Imigca Yesiginali
Iimpawu zoLwahlulelwano:
Faka imiqondiso esetyenziselwa ukusombulula iingxaki zeebhasi, ukuqinisekisa ukwabiwa ngokufanelekileyo kwezixhobo zeebhasi phakathi kwezixhobo ezininzi ezicela ukufikelela ngaxeshanye.
Iimpawu zokuphazamisa (INTA#, INTB#, INTC#, INTD#):
Isetyenziswa zizixhobo zekhoboka ukuthumela izicelo zokuphazamiseka kumphathi, ezazisa ngeziganeko ezithile okanye utshintsho lwemeko.
Ngamafutshane, iinkcazo zesignali ye-PCI SLOT ziquka inkqubo entsonkothileyo yemigca yesignali enoxanduva lokudluliselwa kwedatha, ulawulo lwesixhobo, ingxelo yeempazamo, kunye nokuphazamiseka kokuphathwa kwebhasi ye-PCI. Nangona ibhasi ye-PCI ithathelwe indawo ziibhasi ze-PCIe ezisebenza kakuhle, i-PCI SLOT kunye neenkcazo zayo zesignali zihlala zibalulekile kwiinkqubo ezininzi ezindala kunye nezicelo ezithile.
