Izincazelo zesignali ye-PCI SLOT

Izincazelo zesignali ye-PCI SLOT
I-PCI SLOT, noma i-PCI expansion slot, isebenzisa isethi yemigqa yesignali evumela ukuxhumana nokulawula phakathi kwamadivayisi axhunywe ebhasini le-PCI. Lezi zimpawu zibalulekile ekuqinisekiseni ukuthi amadivayisi angadlulisa idatha futhi aphathe izimo zawo ngokwephrothokholi ye-PCI. Nazi izici eziyinhloko zezincazelo zesignali ye-PCI SLOT:
Imigqa Yesignali Ebalulekile
1. Ibhasi Lekheli/Idatha (AD[31:0]):
Lona umugqa oyinhloko wokudlulisa idatha ebhasini le-PCI. Uhlanganisiwe ukuze uthwale amakheli womabili (ngesikhathi sezigaba zamakheli) kanye nedatha (ngesikhathi sezigaba zedatha) phakathi kwedivayisi kanye nomphathi.
2. UHLELO #:
Iqhutshwa yidivayisi eyinhloko yamanje, i-FRAME# ikhombisa ukuqala kanye nobude bokufinyelela. Ukuqinisekiswa kwayo kuphawula ukuqala kokudluliselwa, futhi ukuphikelela kwayo kubonisa ukuthi ukudluliselwa kwedatha kuyaqhubeka. Ukwehliswa kokuqinisekiswa kukhombisa ukuphela kwesigaba sokugcina sedatha.
3. IRDY# (Isiqalisi Silungele):
Kubonisa ukuthi idivayisi eyinhloko isilungele ukudlulisa idatha. Phakathi nomjikelezo ngamunye wewashi lokudlulisa idatha, uma i-master ingashayela idatha ebhasini, iqinisekisa i-IRDY#.
4. I-DEVSEL# (Ukukhetha Idivayisi):
Iqhutshwa yidivayisi yesigqila eqondiwe, i-DEVSEL# isho ukuthi idivayisi isilungele ukuphendula ekusebenzeni kwebhasi. Ukubambezeleka ekuqinisekiseni i-DEVSEL# kuchaza ukuthi kuthatha isikhathi esingakanani idivayisi yesigqila ukulungiselela ukuphendula umyalo webhasi.
5. MISA# (Ongakukhetha):
Isiginali yokuzikhethela esetshenziswa ukwazisa idivayisi eyinhloko ukuthi iyeke ukudluliswa kwedatha kwamanje ezimweni ezingavamile, njengalapho idivayisi eqondiwe ingakwazi ukuqedela ukudluliswa.
6. I-PERR# (Iphutha Lokulingana):
Iqhutshwa yidivayisi yesigqila ukubika amaphutha okulingana atholwe ngesikhathi sokudluliswa kwedatha.
7. I-SERR# (Iphutha Lesistimu):
Kusetshenziswa ukubika amaphutha ezingeni lesistimu angabangela imiphumela emibi kakhulu, njengokubhekana namaphutha okulingana noma amaphutha okulingana ngokulandelana kwemiyalo ekhethekile.
Imigqa Yesignali Yokulawula
1. I-Command/Byte Enable Multiplex (C/BE[3:0]#):
Iphatha imiyalo yebhasi ngesikhathi sezigaba zekheli futhi i-byte ivumela amasignali ngesikhathi sezigaba zedatha, inquma ukuthi yimaphi ama-byte ebhasini le-AD[31:0] ayidatha evumelekile.
2. I-REQ# (Isicelo Sokusebenzisa Ibhasi):
Iqhutshwa yidivayisi efisa ukulawula ibhasi, ikhombisa isicelo sayo kumlamuli.
3. I-GNT# (Imvume Yokusebenzisa Ibhasi):
Iqhutshwa ngumlamuli, i-GNT# ikhombisa kudivayisi ecelayo ukuthi isicelo sayo sokusebenzisa ibhasi sivunyiwe.
Eminye Imigqa Yesiginali
Izimpawu Zokulamula:
Faka amasignali asetshenziselwa ukuxazulula izinkinga zamabhasi, ukuqinisekisa ukwabiwa okufanele kwezinsizakusebenza zamabhasi phakathi kwamadivayisi amaningi acela ukufinyelela ngasikhathi sinye.
Izimpawu Zokuphazamisa (INTA#, INTB#, INTC#, INTD#):
Kusetshenziswa amadivayisi agqila ukuthumela izicelo zokuphazamiseka kumphathi, ekwazisa ngemicimbi ethile noma izinguquko zesimo.
Ngamafuphi, izincazelo zesignali ye-PCI SLOT zihlanganisa uhlelo oluyinkimbinkimbi lwemigqa yesignali olunesibopho sokudluliswa kwedatha, ukulawula idivayisi, ukubika amaphutha, kanye nokuphazamiseka kokuphathwa kwebhasi le-PCI. Nakuba ibhasi le-PCI lithathelwe indawo amabhasi e-PCIe asebenza kahle kakhulu, i-PCI SLOT kanye nezincazelo zayo zesignali zihlala zibalulekile ezinhlelweni eziningi ezindala kanye nezinhlelo zokusebenza ezithile.
