FPGA Xilinx K7 Kintex7 PCIe optical fiber communication

Kufotokozera Kwachidule:

Nawa mwachidule masitepe omwe akukhudzidwa:

Sankhani gawo loyenera la transceiver optical transceiver: Kutengera ndi zofunikira za njira yanu yolumikizirana ndi kuwala, mungafunike kusankha gawo la transceiver optical lomwe limathandizira kutalika komwe mukufuna, kuchuluka kwa data, ndi mawonekedwe ena. Zosankha zodziwika bwino zimaphatikizapo ma module othandizira Gigabit Ethernet (mwachitsanzo, ma module a SFP/SFP+) kapena njira zolumikizirana zothamanga kwambiri (mwachitsanzo, ma module a QSFP/QSFP+).
Lumikizani transceiver ya kuwala ku FPGA: FPGA nthawi zambiri imalumikizana ndi gawo la transceiver optical kudzera pamalumikizidwe othamanga kwambiri. Ma transceivers ophatikizika a FPGA kapena mapini odzipatulira a I/O opangidwa kuti azilankhulana mothamanga kwambiri atha kugwiritsidwa ntchito pachifukwa ichi. Muyenera kutsatira tsatanetsatane wa gawo la transceiver ndi malangizo a kamangidwe kuti mulumikize bwino ku FPGA.
Khazikitsani ma protocol ofunikira ndikuwongolera ma siginecha: Kulumikizana kwakuthupi kukakhazikitsidwa, muyenera kupanga kapena kukonza ma protocol ofunikira ndi ma aligorivimu opangira ma siginecha potumiza ndi kulandira. Izi zitha kuphatikizira kugwiritsa ntchito protocol yofunikira ya PCIe yolumikizirana ndi wolandila, komanso ma aligorivimu owonjezera amasinthidwe omwe amafunikira pakubisa / kutsitsa, kusinthira / kutsitsa, kukonza zolakwika, kapena ntchito zina zokhudzana ndi pulogalamu yanu.
Phatikizani ndi mawonekedwe a PCIe: Xilinx K7 Kintex7 FPGA ili ndi chowongolera cha PCIe chomwe chimalola kuti ilumikizane ndi makina ochezera pogwiritsa ntchito basi ya PCIe. Mufunika kukonza ndikusintha mawonekedwe a PCIe kuti mukwaniritse zofunikira zamakina anu olumikizirana.
Yesani ndikutsimikizira kulumikizanako: Mukangokhazikitsidwa, muyenera kuyesa ndikutsimikizira magwiridwe antchito a fiber optical pogwiritsa ntchito zida zoyenera zoyesera ndi njira. Izi zitha kuphatikizira kutsimikizira kuchuluka kwa data, kuchuluka kwa zolakwika pang'ono, ndi machitidwe onse adongosolo.

Mafotokozedwe Akatundu:

DDR3 SDRAM: 16GB DDR3 64bit basi, mlingo wa data 1600Mbps
QSPI Flash: Chidutswa cha 128mbit QSPIFLASH, chomwe chitha kugwiritsidwa ntchito pamafayilo osintha a FPGA ndikusunga deta ya ogwiritsa ntchito.
Mawonekedwe a PCLEX8: Mawonekedwe okhazikika a PCLEX8 amagwiritsidwa ntchito polumikizana ndi kulumikizana kwa PCIE pa bolodi lamakompyuta. Imathandizira PCI, Express 2.0 muyezo. Mlingo wolumikizana ndi njira imodzi ukhoza kukhala wokwera mpaka 5Gbps
USB UART siriyo doko: doko siriyo, kulumikiza kwa PC kudzera miniusb chingwe kuchita serial kulankhulana
Khadi la Micro SD: Mpando wa khadi la Microsd njira yonse, mutha kulumikiza khadi ya Microsd
Sensor Kutentha: Sensor Sensor Sensor Chip LM75, yomwe imatha kuyang'anira kutentha kwa chilengedwe kuzungulira gulu lachitukuko
FMC kutambasuka doko: ndi FMC HPC ndi FMCLPC, amene akhoza n'zogwirizana ndi osiyanasiyana makhadi kukula gulu kukula
ERF8 mkulu -speed kugwirizana terminal: 2 ERF8 madoko, amene amathandiza kopitilira muyeso -high -liwiro chizindikiro kufala 40pin kutambasuka: osungika ambiri ukugwirizana IO mawonekedwe ndi 2.54mm40pin, ogwira O ali 17 awiriawiri, thandizo 3.3V
Kulumikizana kwapang'onopang'ono kwa mulingo ndi mulingo wa 5V kumatha kulumikiza zotumphukira zamitundu yosiyanasiyana -cholinga cha 1O
SMA terminal; Mitu 13 yapamwamba kwambiri ya golide -yokutidwa ndi SMA, yomwe ndi yabwino kwa ogwiritsa ntchito kuti agwirizane ndi makhadi okulitsa a AD/DA FMC kuti atolere ma sign ndi kukonza.
Kuwongolera koloko: Gwero la mawotchi angapo. Izi zikuphatikiza gwero la wotchi ya 200MHz SIT9102
