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.
