I-FPGA Xilinx K7 Kintex7 PCIe optical fiber communication

Nakhu ukubuka konke okujwayelekile kwezinyathelo ezihilelekile:

1. Khetha imojula ye-optical transceiver efanelekile: Ngokuya ngezidingo ezithile zohlelo lwakho lokuxhumana olubonayo, uzodinga ukukhetha imojuli ye-optical transceiver esekela ubude begagasi obufunekayo, isilinganiso sedatha, nezinye izici. Izinketho ezivamile zihlanganisa amamojula asekela i-Gigabit Ethernet (isb., amamojula e-SFP/SFP+) noma amazinga okuxhumana abona ngesivinini esiphezulu (isb, amamojula e-QSFP/QSFP+).
2. Xhuma i-transceiver ebonakalayo ku-FPGA: I-FPGA ivamise ukuxhumana nemojuli ye-optical transceiver ngokusebenzisa izixhumanisi ze-serial ezinesivinini esikhulu. Ama-transceivers ahlanganisiwe e-FPGA noma izikhonkwane ze-I/O ezizinikele eziklanyelwe ukuxhumana kwe-serial okunesivinini esiphezulu zingasetshenziselwa le njongo. Kuzodingeka ulandele imininingwane yemojuli ye-transceiver kanye nemihlahlandlela yokuklama eyireferensi ukuze uyixhume kahle ku-FPGA.
3. Sebenzisa izivumelwano ezidingekayo kanye nokucutshungulwa kwesignali: Uma uxhumano olubonakalayo selumisiwe, uzodinga ukuthuthukisa noma ukulungisa izivumelwano ezidingekayo kanye nama-algorithms okucubungula isignali ukuze kudluliselwe idatha nokwamukela. Lokhu kungafaka ukusebenzisa iphrothokholi edingekayo ye-PCIe yokuxhumana nohlelo lomsingathi, kanye nanoma imaphi ama-algorithms engeziwe okucubungula isignali adingekayo ekubhalweni kwekhodi/ukukhipha ikhodi, ukumodulisa/ukwehlisa, ukulungisa amaphutha, noma eminye imisebenzi eqondene nohlelo lwakho lokusebenza.
4. Hlanganisa ne-PCIe interface: I-Xilinx K7 Kintex7 FPGA inesilawuli se-PCIe esakhelwe ngaphakathi esivumela ukuthi ixhumane nesistimu yokusingatha isebenzisa ibhasi le-PCIe. Kuzodingeka ulungise futhi uvumelanise isixhumi esibonakalayo se-PCIe ukuze uhlangabezane nezidingo ezithile zohlelo lwakho lokuxhumana olubonakalayo.
5. Hlola futhi uqinisekise ukuxhumana: Uma sekuqaliwe, uzodinga ukuhlola futhi uqinisekise ukusebenza kokuxhumana kwe-fiber optical usebenzisa amathuluzi okuhlola afanelekile kanye nezindlela. Lokhu kungabandakanya ukuqinisekisa izinga ledatha, izinga lephutha elincane, nokusebenza kwesistimu kukonke.
