Ibisobanuro by'ikimenyetso cya PCI SLOT
PCI SLOT, cyangwa PCI expansion slot, ikoresha umurongo w'ibimenyetso bifasha itumanaho no kugenzura hagati y'ibikoresho bihujwe na PCI bisi. Ibi bimenyetso ni ingenzi cyane kugira ngo ibikoresho bishobore kohereza amakuru no gucunga imiterere yabyo hakurikijwe protocole ya PCI. Dore ingingo z'ingenzi z'ibisobanuro bya PCI SLOT:
Imirongo y'Ibimenyetso by'Ingenzi
1. Aderesi/Ibiro by'amakuru (AD [31:0]):
Uyu ni wo murongo w'ibanze wo kohereza amakuru kuri bisi ya PCI. Ugizwe n'ibice byinshi kugira ngo utware aderesi zombi (mu gihe cy'aderesi) n'amakuru (mu gihe cy'amakuru) hagati y'igikoresho n'umukozi wacyo.
2. IFREMU #:
Iyobowe n'igikoresho gikuru kiriho ubu, FRAME# yerekana intangiriro n'igihe cyo kwinjira. Ibyemeza bigaragaza intangiriro yo kohereza amakuru, kandi gukomeza kwayo bigaragaza ko kohereza amakuru bikomeje. Guhagarika kwemeza bigaragaza iherezo ry'icyiciro cya nyuma cy'amakuru.
3. IRDY# (Itangiriro ryiteguye):
Bigaragaza ko igikoresho cya master cyiteguye kohereza amakuru. Muri buri saha yo kohereza amakuru, iyo master ishobora gushyira amakuru muri bisi, ishimangira IRDY#.
4. DEVSEL# (Guhitamo igikoresho):
Iyobowe n'igikoresho cya serve kigamije, DEVSEL# igaragaza ko igikoresho cyiteguye gusubiza imikorere ya bisi. Gutinda kwemeza DEVSEL# bigena igihe igikoresho cya serve gifata kugira ngo cyitegure gusubiza itegeko rya bisi.
5. GUHAGARARA # (Uburyo bwo guhitamo):
Ikimenyetso cy’ubudakemwa gikoreshwa mu kumenyesha igikoresho gikuru guhagarika kohereza amakuru mu bihe bidasanzwe, nko mu gihe igikoresho kidashoboye kurangiza kohereza amakuru.
6. PERR# (Ikosa ry'ubusumbane):
Biterwa n'igikoresho cya slave kugira ngo gitange raporo ku makosa ya parite yabonetse mu gihe cyo kohereza amakuru.
7. SERR# (Ikosa rya sisitemu):
Byakoreshejwe mu gutanga raporo ku makosa yo ku rwego rwa sisitemu ashobora guteza ingaruka mbi, nko gukemura amakosa y’uburinganire cyangwa amakosa y’uburinganire mu buryo bwihariye bw’amabwiriza.
Imirongo y'ibimenyetso byo kugenzura
1. Gukoresha command/byte (C/BE[3:0]#) mu gukora Multiplex (Command/Byte Enable Multiplex):
Itwara amabwiriza ya bisi mu gihe cy'aderesi na byte ikoresha ibimenyetso mu gihe cy'amakuru, ikagena byte kuri bisi ya AD[31:0] ari amakuru yemewe.
2. REQ# (Gusaba gukoresha bisi):
Itwarwa n'igikoresho cyifuza kugenzura bisi, kimenyesha umukemurampaka icyifuzo cyacyo.
3. GNT# (Inguzanyo yo gukoresha bisi):
Iyobowe n'umukemurampaka, GNT# ibwira igikoresho gisaba ko icyifuzo cyayo cyo gukoresha bisi cyemejwe.
Indi mirongo y'ibimenyetso
Ibimenyetso by'Ubukemurampaka:
Shyiramo ibimenyetso bikoreshwa mu guca imanza za bisi, urebe neza ko umutungo wa bisi utangwa mu buryo buboneye hagati y’ibikoresho byinshi bisaba kwinjira icyarimwe.
Ibimenyetso byo guhagarika (INTA#, INTB#, INTC#, INTD#):
Ibikoresho by'ubucakara bikoreshwa mu kohereza ubusabe bwo guhagarika amakuru kuri nyir'urubuga, bimenyesha ibintu byihariye cyangwa impinduka za leta.
Muri make, ibisobanuro bya PCI SLOT birimo uburyo bugoye bw'imirongo y'ibimenyetso ishinzwe kohereza amakuru, kugenzura igikoresho, gutanga raporo y'amakosa, no guhagarika imikorere ya bisi ya PCI. Nubwo bisi ya PCI yasimbuwe na bisi za PCIe zikora neza, PCI SLOT n'ibisobanuro byayo bya signal biracyari ingenzi muri sisitemu nyinshi za kera no mu buryo bwihariye.
