I-PCI Slot Signal Deserts

I-PCI Slot Signal Deserts
I-PCI Slot, noma i-PCI Expansion Slot, isebenzisa isethi yemigqa yesiginali enika amandla ukuxhumana nokulawula phakathi kwamadivayisi axhunywe ebhasini le-PCI. Lezi zimpawu zibalulekile ekuqinisekiseni ukuthi amadivaysi angadlulisa idatha futhi aphathe izifundazwe zawo ngokusho kwephrothokholi ye-PCI. Nazi izici eziphambili zezincazelo zesiginali ye-PCI Slot:
Imigqa yesiginali ebalulekile
1. Ikheli / Ibhasi ledatha (AD [31: 0]):
Lona umugqa wokuhambisa idatha oyinhloko ebhasini le-PCI. Kuningi okuphindwe kabili ukuthwala womabili amakheli (ngesikhathi sezigaba zekheli) nedatha (ngesikhathi sezigaba zedatha) phakathi kwensiza nomgcini.
2. Uhlaka #:
Iqhutshwa yidivaysi yamanje ye-master master, ifreyimu # ikhombisa ukuqala nokufika kwesikhathi sokufinyelela. Ukuvuma kwalo kuphawula ukuqala kokudluliselwa, futhi ukuphikelela kwalo kukhombisa ukuthi ukudluliswa kwedatha kuyaqhubeka. Amasignali wokuqinisekisa ukuphela kwesigaba sedatha yokugcina.
3. I-IRDY # (Inistiator Ready):
Ibonisa ukuthi idivaysi enkulu isilungele ukudlulisa idatha. Ngesikhathi somjikelezo ngamunye wokudluliswa kwedatha, uma inkosi ingashayela idatha ebhasini, igcizelela i-IRDY #.
4. I-Devsel # (Khetha Idivayisi):
Iqhutshwa yithuluzi lesigqila elihlosiwe, i-devsel # # libonisa ukuthi idivaysi isilungele ukuphendula ekusebenzeni kwebhasi. Ukubambezeleka ekubizeleni i-devsel # kuchazwa ukuthi kuthatha isikhathi esingakanani idivaysi yenceku ukulungiselela ukuphendula umyalo webhasi.
5. Misa # (ngokuzithandela):
Isiginali ongayikhetha esetshenziselwa ukwazisa idivaysi eyi-master ukumisa ukudluliswa kwedatha yamanje ezimweni ezihlukile, njengokuthi lapho idivaysi eqondisiwe ingakwazi ukuqeda ukudluliswa.
6. I-Perr # (Iphutha lePartity):
Iqhutshwa yithuluzi lesigqila ukubika amaphutha engane atholwe ngesikhathi sokudluliswa kwedatha.
7. I-SERR # (Iphutha lesistimu):
Kusetshenziselwa ukubika amaphutha weleveli yohlelo olungadala imiphumela eyinhlekelele, efana namaphutha entengo noma amaphutha e-parity ngokulandelana okukhethekile komyalo.
Lawula imigqa yesiginali
1. Umyalo / Byte Nika amandla i-Multiplex (C / Be [3: 0] #):
Iphatha imiyalo yebhasi ngesikhathi sezigaba zekheli kanye ne-Byte Nika amandla amasiginali ngesikhathi sezigaba zedatha, ukunquma ukuthi yimaphi amabhasi ku-AD [31: 0] Ibhasi livumelekile.
2. # (Isicelo sokusebenzisa ibhasi):
Iqhutshwa yithuluzi elifisa ukuthola ukulawula ibhasi, ukusayina isicelo salo kwi-arbiter.
3. I-GNT # (nikeza ukusebenzisa ibhasi):
Iqhutshwa yi-arbiter, i-GNT # ikhombisa kudivayisi ecelayo ukuthi isicelo sayo sokusebenzisa ibhasi selinikezwe.
Eminye imigqa yesiginali
Amasiginali okulamula:
Faka amasiginali asetshenziselwa ukulamula ngebhasi, aqinisekise ukwabiwa okulungile kwezinsizakusebenza zamabhasi phakathi kwamadivayisi amaningi acela ukufinyelela ngasikhathi sinye.
Izimpawu eziphazamisayo (I-ITA #, Intb #, Intc #, Intd #):
Kusetshenziswa amadivaysi ezinceku ukuthumela izicelo eziphazamisa umgcini, zikwazisa ngemicimbi ethile noma izinguquko zombuso.
Ngamafuphi, izincazelo zesiginali ye-PCI slot zifaka uhlelo oluyinkimbinkimbi lwemigqa yesiginali ebhekele ukudluliswa kwedatha, ukulawulwa kwamadivayisi, ukubikwa kwephutha, nokuphazamisa ukuphazamiseka ebhasini le-PCI. Yize ibhasi le-PCI lidluliselwe amabhasi e-PCIE aphezulu ngokusebenza okuphezulu, i-PCI Slot nezincazelo zalo zesiginali zihlala zibalulekile ezinhlelweni eziningi zefa nezinhlelo ezithile.
