PCI Slot chiratidzo tsananguro
Iyo PCI SLOT, kana PCI yekuwedzera slot, inoshandisa seti yemitsara yemasaini inogonesa kutaurirana uye kutonga pakati pemidziyo yakabatana nePCI bhazi. Aya masaini akakosha pakuona kuti zvishandiso zvinokwanisa kuendesa data uye kutonga nyika dzazvo zvinoenderana nePCI protocol. Heano iwo makuru maficha ePCI SLOT masaini tsananguro:
Essential Signal Lines
1. Kero/Data Bus (AD[31:0]):
Iyi ndiyo yekutanga data data line paPCI bhazi. Iyo yakapetwa kaviri kutakura ese kero (panguva yekero nhanho) uye data (panguva yedata data) pakati pemudziyo nemugamuchiri.
2. FRAME#:
Inotungamirwa neyazvino master mudziyo, FRAME# inoratidza kutanga uye nguva yekuwana. Kutaura kwayo kunoratidza kutanga kwekutamisa, uye kushingirira kwayo kunoratidza kuti kuendesa data kunoenderera. De-assertion inoratidza kupera kwechikamu chekupedzisira che data.
3. IRDY# (Initiator Yakagadzirira):
Inoratidza kuti iyo master mudziyo yakagadzirira kuendesa data. Munguva yega yega kutenderera kwekufambisa data, kana tenzi achigona kutyaira data mubhazi, inoti IRDY#.
4. DEVSEL# (Chishandiso Sarudza):
Inotyairwa nechishandiso chakanangwa chenhapwa, DEVSEL# inoratidza kuti chishandiso chagadzirira kupindura kushanda kwebhazi. Kunonoka kutaura DEVSEL# kunotsanangura kuti zvinotora nguva yakareba sei mudziyo wenhapwa kugadzirira kupindura murairo webhazi.
5. MIRA# (Sarudzo):
Chiratidzo chekusarudzika chinoshandiswa kuzivisa iyo master mudziyo kumisa yazvino data kuendesa mune akasarudzika kesi, senge kana iyo yakanangwa mudziyo usingakwanise kupedzisa kutamisa.
6. PERR# (Parity Error):
Inotyairwa nemudziyo wevaranda kutaurira zvikanganiso zvakaonekwa panguva yekuendesa data.
7. SERR# (Kukanganisa kweSystem):
Inoshandiswa kushuma kukanganisa-level kukanganisa izvo zvinogona kukonzera njodzi, senge kero zvikanganiso zveparity kana zvikanganiso zveparity mukutevedzana kwemirairo.
Kudzora Mitsetse Yechiratidzo
1. Raira/Byte Gonesa Multiplex (C/BE[3:0]#):
Inotakura mirairo yebhazi panguva yekero nhanho uye byte inogonesa masaini panguva yedata data, kuona kuti ndeapi mabhaiti paAD[31:0] bhazi idata rechokwadi.
2. REQ# (Chikumbiro Chekushandisa Bhazi):
Inotyairwa nemudziyo unoda kutora kutonga kwebhazi, zvichiratidza chikumbiro chayo kune arbiter.
3. GNT# (Chipo cheKushandisa Bhazi):
Inotyairwa nearbiter, GNT# inoratidza kune mudziyo unokumbira kuti chikumbiro chayo chekushandisa bhazi chapihwa.
Mamwe Masignal Lines
Arbitration Signals:
Sanganisira masiginecha anoshandiswa pakugadzirisa mabhazi, kuve nechokwadi chekugovewa kwakanaka kwezviwanikwa zvemabhazi pakati pemidziyo yakawanda inokumbira kupinda panguva imwe chete.
Kuvhiringidza Zviratidzo (INTA#, INTB#, INTC#, INTD#):
Inoshandiswa nemidziyo yevaranda kutumira zvikumbiro zvekuvhiringidza kune muenzi, achizivisa nezve zviitiko chaizvo kana shanduko yenyika.
Muchidimbu, iyo PCI SLOT chiratidzo chetsanangudzo dzinosanganisira yakaoma sisitimu yemitsara yemasaini ine mutoro wekufambisa data, kutonga kwemudziyo, kukanganisa kukanganisa, uye kukanganisa kubata paPCI bhazi. Kunyangwe bhazi rePCI rakatsiviwa nemabhazi ePCIe epamusoro, iyo PCI SLOT uye tsananguro dzayo dzechiratidzo dzinoramba dzakakosha mumasisitimu mazhinji enhaka uye mashandisirwo chaiwo.
