FPGA Xilinx K7 Kintex7 PCIe unxibelelwano lwefiber optical

Nantsi isishwankathelo samanyathelo abandakanyekayo:

1. Khetha imodyuli efanelekileyo ye-optical transceiver: Kuxhomekeke kwiimfuno ezithile zenkqubo yakho yonxibelelwano lwamehlo, kuya kufuneka ukhethe imodyuli ye-optical transceiver exhasa ubude obufunekayo, izinga ledatha, kunye nezinye iimpawu.Izinketho eziqhelekileyo ziquka iimodyuli ezixhasa i-Gigabit Ethernet (umzekelo, iimodyuli ze-SFP / SFP +) okanye imigangatho yonxibelelwano ye-optical ephezulu (umzekelo, iimodyuli ze-QSFP / QSFP +).
2. Xhuma i-transceiver ye-optical kwi-FPGA: I-FPGA ngokuqhelekileyo idibanisa kunye nemodyuli ye-transceiver optical ngokusebenzisa i-serial-speed serial links.Ii-transceivers ezihlanganisiweyo zeFPGA okanye izikhonkwane ze-I/O ezizinikeleyo ezilungiselelwe unxibelelwano olukhawulezayo lwe-serial zingasetyenziselwa le njongo.Kuya kufuneka ulandele idatha yemodyuli yetransceiver kunye nezikhokelo zoyilo lwereferensi ukuyidibanisa ngokufanelekileyo kwiFPGA.
3. Phumeza iiprothokholi eziyimfuneko kunye nokusetyenzwa komqondiso: Nje ukuba uqhagamshelo lomzimba lusekiwe, kuya kufuneka uphuhlise okanye ulungiselele iiprothokholi eziyimfuneko kunye ne-algorithms yokusetyenzwa komqondiso wogqithiso lwedatha kunye nolwamkelo.Oku kunokubandakanya ukuphumeza i-protocol ye-PCIe eyimfuneko yonxibelelwano kunye nenkqubo yokusingatha, kunye nayo nayiphi na i-algorithms yokulungiswa kwesignali eyongezelelweyo efunekayo kwi-encoding / decoding, imodulation / demodulation, ukulungiswa kwempazamo, okanye eminye imisebenzi ethile kwisicelo sakho.
4. Hlanganisa ne-PCIe interface: I-Xilinx K7 Kintex7 FPGA inomlawuli we-PCIe eyakhelweyo evumela ukuba inxibelelane nenkqubo yokusingatha usebenzisa ibhasi ye-PCIe.Kuya kufuneka uqwalasele kwaye uhlengahlengise ujongano lwePCIe ukuhlangabezana neemfuno ezithile zenkqubo yakho yonxibelelwano lwamehlo.
5. Uvavanye kwaye uqinisekise unxibelelwano: Nje ukuba luphunyeziwe, kuya kufuneka uvavanye kwaye uqinisekise ukusebenza konxibelelwano lwefiber optical fiber usebenzisa izixhobo ezifanelekileyo zovavanyo kunye neendlela.Oku kunokubandakanya ukuqinisekisa izinga ledatha, izinga lempazamo encinci, kunye nokusebenza kwenkqubo iyonke.
