FPGA Xilinx K7 Kintex7 PCIe itumanaho rya fibre optique

Dore rusange muri rusange intambwe zirimo:

1. Hitamo icyiciro gikwiye cyo guhinduranya module: Ukurikije ibisabwa byihariye bya sisitemu y'itumanaho rya optique, wakenera guhitamo optique ya transceiver module ishyigikira uburebure bwifuzwa, igipimo cyamakuru, nibindi biranga. Amahitamo asanzwe arimo module ishyigikira Ethernet ya Gigabit (urugero, SFP / SFP + modules) cyangwa ibipimo byihuta byitumanaho ryiza (urugero, QSFP / QSFP + modules).
2. Huza optique ya optique kuri FPGA: Ubusanzwe FPGA irahuza na optique ya transceiver module binyuze mumurongo wihuse wihuta. FPGA ihuriweho na transcevers cyangwa I / O byabugenewe byabugenewe byihuta byitumanaho byihuta birashobora gukoreshwa kubwiyi ntego. Uzakenera gukurikiza module ya transceiver module ya datasheet hamwe nubuyobozi bwo gushushanya kugirango uyihuze neza na FPGA.
3. Shyira mubikorwa protocole ikenewe no gutunganya ibimenyetso: Iyo ihuza ryumubiri rimaze gushingwa, wakenera gukora cyangwa gushiraho protocole ikenewe hamwe no gutunganya ibimenyetso bya algorithm yo kohereza amakuru no kwakira. Ibi birashobora kubamo gushyira mubikorwa protocole ya PCIe ikenewe kugirango itumanaho hamwe na sisitemu yakiriye, kimwe n’ibindi bikoresho byongeweho gutunganya ibimenyetso bisabwa kuri kodegisi / decoding, modulation / demodulation, gukosora amakosa, cyangwa indi mirimo yihariye isaba.
4. Kwinjiza hamwe na interineti ya PCIe: Xilinx K7 Kintex7 FPGA ifite imashini yubatswe ya PCIe ituma ivugana na sisitemu yakira ikoresheje bisi ya PCIe. Uzakenera gushiraho no guhuza PCIe kugirango uhuze ibisabwa byihariye bya sisitemu y'itumanaho rya optique.
5. Gerageza kandi ugenzure itumanaho: Numara gushyirwa mubikorwa, ugomba kugerageza no kugenzura imikorere ya fibre optique ukoresheje ibikoresho byikizamini hamwe nuburyo bukwiye. Ibi birashobora kubamo kugenzura igipimo cyamakuru, igipimo cyamakosa, hamwe nibikorwa bya sisitemu muri rusange.
