PCI slot iinkcazelo zomqondiso

PCI slot iinkcazelo zomqondiso
I-PCI SLOT, okanye i-PCI yokwandisa i-slot, isebenzisa isethi yemigca yesignali eyenza unxibelelwano kunye nolawulo phakathi kwezixhobo eziqhagamshelwe kwibhasi ye-PCI. Le miqondiso ibalulekile ekuqinisekiseni ukuba izixhobo zinokudlulisela idatha kwaye zilawule amazwe azo ngokwenkqubo yePCI. Nantsi imiba ephambili yenkcazelo yomqondiso we-PCI Slot:
Imigca yeMiqondiso ebalulekileyo
1. Idilesi/Ibhasi Yedatha (AD[31:0]):
Lo ngowona mgca wokuqala wothumelo lwedatha kwibhasi yePCI. I-multiplex ukuthwala zombini iidilesi (ngexesha lezigaba zeedilesi) kunye nedatha (ngexesha lezigaba zedatha) phakathi kwesixhobo kunye nomamkeli.
2. ISAKHIWO#:
Iqhutywa sisixhobo esingundoqo sangoku, FRAME# ibonisa ukuqala kunye nobude bexesha lofikelelo. Ukutsho kwayo kubonisa ukuqala kokudluliselwa, kwaye ukuphikelela kwayo kubonisa ukuba ukuhanjiswa kwedatha kuyaqhubeka. I-De-assertion ibonisa ukuphela kwesigaba sokugqibela sedatha.
3. IRDY# (Umqalisi ulungile):
Ibonisa ukuba isixhobo esiyintloko sikulungele ukudlulisa idatha. Ngexesha lomjikelo wewotshi nganye yokudluliselwa kwedatha, ukuba inkosi inokuqhuba idatha kwibhasi, ithi IRDY#.
4. DEVSEL# (Isixhobo Khetha):
Iqhutywa sisixhobo sekhoboka ekujoliswe kuso, i-DEVSEL# ibonisa ukuba isixhobo sikulungele ukuphendula kumsebenzi webhasi. Ukulibaziseka ekuqinisekiseni i-DEVSEL# ichaza ukuba kuthatha ixesha elingakanani isixhobo samakhoboka ukulungiselela ukuphendula kumyalelo webhasi.
5. YIMA# (Ngokhetho):
Umqondiso ozikhethelayo osetyenziselwa ukwazisa isixhobo esikhulu ukumisa ugqithiso lwedatha lwangoku kwiimeko ezizodwa, njengaxa isixhobo ekujoliswe kuso singakwazi ukugqiba ugqithiselo.
6. PERR# (Impazamo yokuLingana):
Iqhutywa sisixhobo sobukhoboka ukuchaza iimpazamo zokulingana ezifunyenwe ngexesha lokudluliselwa kwedatha.
7. SERR# (Impazamo yeNkqubo):
Isetyenziselwa ukuchaza iimpazamo zenqanaba lenkqubo ezinokubangela iziphumo eziyingozi, ezifana neempazamo zokulinganisa okanye iimpazamo zokulingana kulandelelwano lomyalelo okhethekileyo.
Lawula iilayini zeSiqondiso
1. Umyalelo/Byte Yenza iMultiplex (C/BE[3:0]#):
Ithwala imiyalelo yebhasi ngexesha leedilesi kunye ne-byte yenza izibonakaliso ngexesha lezigaba zedatha, ukugqiba ukuba yiyiphi i-bytes kwi-AD [31: 0] ibhasi idatha esebenzayo.
2. REQ# (Isicelo sokuSebenzisa iBhasi):
Iqhutywe sisixhobo esinqwenela ukufumana ulawulo lwebhasi, ibonakalisa isicelo sayo kwi-arbiter.
3. GNT# (ISibonelelo sokuSebenzisa iBhasi):
Iqhutywa ngumlamli, i-GNT# ibonisa kwisixhobo esicelayo ukuba isicelo sayo sokusebenzisa ibhasi sivunyiwe.
Eminye iMiqondiso yeMilayini
Imiqondiso yolamlo:
Bandakanya imiqondiso esetyenziselwa ulamlo lwebhasi, ukuqinisekisa ulwabiwo olufanelekileyo lwezibonelelo zebhasi phakathi kwezixhobo ezininzi ezicela ukufikelela ngaxeshanye.
Imiqondiso yokuphazamisa (INTA#, INTB#, INTC#, INTD#):
Isetyenziswe zizixhobo zekhoboka ukuthumela izicelo zokuphazamiseka kumamkeli, ukwazisa ngeziganeko ezithile okanye utshintsho lwelizwe.
Isishwankathelo, iinkcazo zesignali ye-PCI SLOT zibandakanya inkqubo enzima yemigca yesiginali enoxanduva lokudluliselwa kwedatha, ulawulo lwesixhobo, ingxelo yempazamo, kunye nokuphazamiseka kokuphatha kwibhasi yePCI. Nangona ibhasi ye-PCI iye yathatyathelwa indawo ziibhasi ze-PCIe ezisebenza kakhulu, i-PCI SLOT kunye neenkcazo zayo zomqondiso zihlala zibalulekile kwiinkqubo ezininzi zelifa kunye nezicelo ezithile.
