Matanthauzidwe a chizindikiro cha PCI SLOT
PCI SLOT, kapena malo owonjezera a PCI, amagwiritsa ntchito mizere ya zizindikiro zomwe zimathandiza kulumikizana ndi kuwongolera pakati pa zipangizo zolumikizidwa ku basi ya PCI. Zizindikiro izi ndizofunikira kwambiri poonetsetsa kuti zipangizo zimatha kusamutsa deta ndikuwongolera momwe zilili malinga ndi protocol ya PCI. Nazi mfundo zazikulu za matanthauzidwe a chizindikiro cha PCI SLOT:
Mizere Yofunikira ya Zizindikiro
1. Adilesi/Basi ya Deta (AD[31:0]):
Iyi ndi njira yoyamba yotumizira deta pa basi ya PCI. Imapangidwa kuti inyamule maadiresi onse awiri (nthawi ya ma adilesi) ndi deta (nthawi ya data) pakati pa chipangizocho ndi wolandila.
2. CHITHUNZI CHA FRAME:
Motsogozedwa ndi chipangizo chachikulu chomwe chilipo, FRAME# imasonyeza kuyamba ndi nthawi yofikira. Kutsimikizira kwake kumasonyeza kuyamba kwa kusamutsa, ndipo kupirira kwake kumasonyeza kuti kutumiza deta kukupitirira. Kusiya kutsimikizira kumasonyeza kutha kwa gawo lomaliza la deta.
3. IRDY# (Wokonzeka kuyambitsa):
Zimasonyeza kuti chipangizo chachikulu chili chokonzeka kusamutsa deta. Pa nthawi iliyonse yotumizira deta, ngati master ikhoza kuyendetsa deta mu basi, imanena kuti IRDY#.
4. DEVSEL# (Kusankha Chipangizo):
Motsogozedwa ndi chipangizo cha kapolo chomwe chikufunidwa, DEVSEL# imatanthauza kuti chipangizocho chili chokonzeka kuyankha ku ntchito ya basi. Kuchedwa kutsimikizira DEVSEL# kumatanthauza nthawi yomwe chipangizo cha kapolocho chimatenga kukonzekera kuyankha ku lamulo la basi.
5. IMANI # (Mwasankha):
Chizindikiro chosankha chomwe chimagwiritsidwa ntchito kudziwitsa chipangizo chachikulu kuti chiyimitse kusamutsa deta komwe kukuchitika nthawi zina, monga pamene chipangizocho sichingathe kumaliza kusamutsa.
6. PERR# (Cholakwika cha Parity):
Choyendetsedwa ndi chipangizo cha kapolo kuti chifotokoze zolakwika za parity zomwe zapezeka panthawi yotumiza deta.
7. SERR# (Cholakwika cha System):
Amagwiritsidwa ntchito pofotokoza zolakwika za pamlingo wa dongosolo zomwe zingayambitse zotsatira zoopsa, monga kuyankha zolakwika za parity kapena zolakwika za parity muzotsatira zapadera za malamulo.
Mizere ya Zizindikiro Zowongolera
1. Command/Byte Yambitsani Multiplex (C/BE[3:0]#):
Imanyamula malamulo a basi panthawi ya ma adilesi ndipo byte imayatsa zizindikiro panthawi ya data, zomwe zimatsimikiza kuti ndi ma byte ati omwe ali pa AD[31:0] basi omwe ndi deta yolondola.
2. REQ# (Pempho Logwiritsa Ntchito Basi):
Kuyendetsedwa ndi chipangizo chomwe chikufuna kulamulira basi, chikuwonetsa pempho lake kwa woweruza milandu.
3. GNT# (Basi Yogwiritsidwa Ntchito):
Motsogozedwa ndi woweruza milandu, GNT# imauza chipangizo chopempha kuti pempho lake logwiritsa ntchito basi lavomerezedwa.
Mizere Ina ya Zizindikiro
Zizindikiro za Kuthetsa Mikangano:
Phatikizani zizindikiro zomwe zimagwiritsidwa ntchito pokonza mabasi, kuonetsetsa kuti zinthu za basi zikugawidwa bwino pakati pa zipangizo zingapo zomwe zikupempha kuti zilowe nthawi imodzi.
Zizindikiro Zosokoneza (INTA#, INTB#, INTC#, INTD#):
Amagwiritsidwa ntchito ndi zida zogwirira ntchito kutumiza zopempha zosokoneza kwa wolandila, kumudziwitsa za zochitika zinazake kapena kusintha kwa boma.
Mwachidule, matanthauzidwe a chizindikiro cha PCI SLOT akuphatikizapo dongosolo lovuta la mizere ya chizindikiro lomwe limayang'anira kusamutsa deta, kuwongolera chipangizo, kupereka malipoti a zolakwika, ndi kusokoneza magwiridwe antchito pa basi ya PCI. Ngakhale basi ya PCI yalowedwa m'malo ndi mabasi a PCIe ogwira ntchito bwino, PCI SLOT ndi matanthauzidwe ake a chizindikiro akadali ofunikira m'makina ambiri akale ndi ntchito zinazake.
