LFE5U-25F-6BG256C - Madera Ophatikizidwa, Ophatikizidwa, FPGAs (Field Programmable Gate Array)

FPGAs

Tsegulani:
Field Programmable Gate Arrays (FPGAs) atuluka ngati ukadaulo wapamwamba pamapangidwe a digito.Mabwalo ophatikizikawa omwe amatha kutha amapatsa opanga kusinthasintha kosayerekezeka komanso kuthekera kosintha mwamakonda.Munkhaniyi, tikuyang'ana dziko la FPGAs, ndikuwunika momwe amagwirira ntchito, mapindu, komanso momwe amagwiritsira ntchito.Pomvetsetsa kuthekera ndi kuthekera kwa ma FPGA, titha kumvetsetsa momwe asinthira gawo lakapangidwe ka digito.

Kapangidwe ndi ntchito:
Ma FPGA ndi mabwalo a digito osinthika omwe amapangidwa ndi midadada yosinthika, zolumikizirana, ndi midadada yolowetsa/zotulutsa (I/O).Mipiringidzoyi ikhoza kukonzedwa pogwiritsa ntchito chinenero chofotokozera za hardware (HDL) monga VHDL kapena Verilog, zomwe zimalola wopanga kuti afotokoze ntchito ya dera.Ma block block amatha kukhazikitsidwa kuti azichita zinthu zosiyanasiyana, monga kuwerengera masamu kapena ntchito zomveka, popanga tebulo loyang'ana (LUT) mkati mwa logic block.Ma interconnects amakhala ngati njira zolumikizira midadada yosiyanasiyana yamalingaliro, kupangitsa kulumikizana pakati pawo.Module ya I / O imapereka mawonekedwe a zida zakunja kuti zigwirizane ndi FPGA.Mapangidwe osinthika kwambiriwa amathandizira opanga kupanga mabwalo ovuta a digito omwe amatha kusinthidwa kapena kukonzedwanso.

Ubwino wa FPGAs:
Ubwino waukulu wa ma FPGA ndikusinthasintha kwawo.Mosiyana ndi ma circuit-specific integrated circuits (ASICs), omwe ndi olimba kuti azigwira ntchito zinazake, ma FPGA amatha kusinthidwanso ngati pakufunika.Izi zimalola opanga kupanga mawonekedwe mwachangu, kuyesa ndikusintha mabwalo popanda ndalama zopangira ASIC.Ma FPGA amaperekanso njira zazifupi zachitukuko, kuchepetsa nthawi kupita kumsika pamakina ovuta amagetsi.Kuphatikiza apo, ma FPGA amafanana kwambiri m'chilengedwe, kuwapangitsa kukhala oyenera kugwiritsa ntchito mozama kwambiri monga luntha lochita kupanga, kubisa kwa data, komanso kukonza ma siginecha munthawi yeniyeni.Kuphatikiza apo, ma FPGA ndiogwiritsa ntchito mphamvu zambiri kuposa mapurosesa azinthu zonse chifukwa amatha kusinthidwa ndendende momwe akufunira, kuchepetsa kugwiritsa ntchito mphamvu kosafunikira.

Ntchito m'mafakitale osiyanasiyana:
Chifukwa cha kusinthasintha kwawo, ma FPGA amagwiritsidwa ntchito m'mafakitale osiyanasiyana.Pakulumikizana patelefoni, ma FPGA amagwiritsidwa ntchito m'malo oyambira ndi ma netiweki ma routers kuti azitha kusanthula zidziwitso zothamanga kwambiri, kupititsa patsogolo chitetezo cha data, ndikuthandizira maukonde ofotokozedwa ndi mapulogalamu.M'makina amagalimoto, ma FPGA amathandizira zida zotsogola zoyendetsa monga kupewa kugundana komanso kuwongolera maulendo apanyanja.Amagwiritsidwanso ntchito pokonza zithunzi zenizeni, zowunikira komanso kuyang'anira odwala pazida zamankhwala.Kuphatikiza apo, ma FPGA ndi ofunikira pazamlengalenga ndi chitetezo, makina opangira ma radar, ma avionics, ndi kulumikizana kotetezeka.Kusinthasintha kwake komanso magwiridwe antchito apamwamba kumapangitsa FPGA kukhala gawo lofunikira paukadaulo wapamwamba kwambiri m'magawo osiyanasiyana.

Mavuto ndi mayendedwe amtsogolo:
Ngakhale ma FPGA ali ndi zabwino zambiri, amaperekanso zovuta zawo.Mapangidwe a FPGA amatha kukhala ovuta, ofunikira ukatswiri komanso ukadaulo wazilankhulo zofotokozera za Hardware ndi kamangidwe ka FPGA.Kuphatikiza apo, ma FPGA amadya mphamvu zambiri kuposa ma ASIC akamagwira ntchito yomweyo.Komabe, kafukufuku wopitilira ndi chitukuko akuthana ndi zovuta izi.Zida zatsopano ndi njira zikupangidwa kuti zifewetse mapangidwe a FPGA ndikuchepetsa kugwiritsa ntchito mphamvu.Pomwe ukadaulo ukupitilira kupita patsogolo, ma FPGA akuyembekezeka kukhala amphamvu kwambiri, osagwiritsa ntchito mphamvu, komanso kupezeka kwa opanga ambiri.

Pomaliza:
Field Programmable Gate Arrays yasintha gawo la kapangidwe ka digito.Kusinthasintha kwawo, kusinthika komanso kusinthika kwawo kumawapangitsa kukhala ofunikira m'mafakitale osiyanasiyana.Kuchokera pamatelefoni kupita pamagalimoto ndi ndege, ma FPGA amathandizira magwiridwe antchito apamwamba komanso magwiridwe antchito apamwamba.Ngakhale zili zovuta, kupita patsogolo kopitilira muyeso kumalonjeza kuthana nazo ndikupititsa patsogolo luso ndi kugwiritsa ntchito zida zodabwitsazi.Pakuchulukirachulukira kwamagetsi ovuta komanso okhazikika, ma FPGA mosakayikira atenga gawo lofunikira pakukonza tsogolo lakapangidwe ka digito.
