FPGA Xilinx K7 Kintex7 PCIe optical fiber kev sib txuas lus

Nov yog ib qho kev piav qhia dav dav ntawm cov kauj ruam uas koom nrog:

1. Xaiv qhov tsim nyog optical transceiver module: Nyob ntawm cov kev cai tshwj xeeb ntawm koj qhov kev sib txuas lus kho qhov muag, koj yuav tsum xaiv qhov optical transceiver module uas txhawb nqa qhov xav tau wavelength, cov ntaub ntawv tus nqi, thiab lwm yam ntxwv. Cov kev xaiv muaj xws li modules txhawb Gigabit Ethernet (piv txwv li, SFP / SFP + modules) lossis cov qauv kev sib txuas lus ceev dua (piv txwv li, QSFP / QSFP + modules).
2. Txuas lub optical transceiver mus rau FPGA: FPGA feem ntau cuam tshuam nrog optical transceiver module los ntawm kev sib txuas ceev ceev. FPGA's integrated transceivers lossis nplooj siab I / O pins tsim rau kev sib txuas lus ceev ceev tuaj yeem siv rau lub hom phiaj no. Koj yuav tsum tau ua raws li cov transceiver module cov ntaub ntawv cov ntaub ntawv thiab siv cov txheej txheem tsim kom zoo txuas rau FPGA.
3. Ua raws li cov txheej txheem tsim nyog thiab kev ua cov teeb liab: Thaum lub cev kev sib txuas tau tsim, koj yuav tsum tsim lossis teeb tsa cov txheej txheem tsim nyog thiab teeb tsa ua cov txheej txheem rau cov ntaub ntawv xa mus thiab txais tos. Qhov no tuaj yeem suav nrog kev siv cov txheej txheem PCIe tsim nyog rau kev sib txuas lus nrog tus tswv tsev, nrog rau cov teeb liab ua haujlwm ntxiv uas yuav tsum tau ua rau encoding / decoding, modulation / demodulation, kho qhov yuam kev, lossis lwm yam haujlwm tshwj xeeb rau koj daim ntawv thov.
4. Kev koom ua ke nrog PCIe interface: Xilinx K7 Kintex7 FPGA muaj ib lub PCIe maub los uas tso cai rau nws sib txuas lus nrog tus tswv tsev siv lub npav PCIe. Koj yuav tsum tau teeb tsa thiab hloov kho PCIe interface kom tau raws li cov cai tshwj xeeb ntawm koj qhov kev sib txuas lus kho qhov muag.
5. Kuaj thiab txheeb xyuas qhov kev sib txuas lus: Thaum ua tiav, koj yuav tsum tau sim thiab txheeb xyuas qhov ua haujlwm ntawm kev sib txuas lus fiber ntau siv cov cuab yeej ntsuas thiab cov txheej txheem tsim nyog. Qhov no tuaj yeem suav nrog kev txheeb xyuas cov ntaub ntawv tus nqi, qhov yuam kev me ntsis, thiab kev ua haujlwm tag nrho ntawm lub cev.
