LFE5U-25F-6BG256C - Imirongo ihuriweho, yashyizwemo, FPGAs (Field Programmable Gate Array)

FPGAs

Intangiriro:
Field Programmable Gate Arrays (FPGAs) yagaragaye nkikoranabuhanga ryateye imbere muburyo bwa sisitemu.Izi porogaramu zishobora guhurizwa hamwe zitanga abashushanya ibintu byoroshye kandi bitigeze bibaho.Muri iyi ngingo, twinjiye mu isi ya FPGAs, dushakisha imiterere, inyungu, nibisabwa.Mugusobanukirwa ubushobozi nubushobozi bwa FPGAs, dushobora kumva uburyo bahinduye murwego rwo gushushanya sisitemu.

Imiterere n'imikorere:
FPGAs nisubirwamo ryumuzunguruko wa digitale ugizwe na porogaramu zishobora gukoreshwa, guhuza, hamwe no kwinjiza / ibisohoka (I / O).Izi bloks zirashobora gutegurwa hakoreshejwe imvugo isobanura ibyuma (HDL) nka VHDL cyangwa Verilog, bigatuma uwashizeho ibishushanyo mbonera byerekana imikorere yumuzunguruko.Guhagarika ibitekerezo birashobora gushyirwaho kugirango bikore ibikorwa bitandukanye, nkibara ryimibare cyangwa ibikorwa bya logique, mugutegura gahunda yo kureba (LUT) murwego rwo guhagarika ibitekerezo.Guhuza bikora nkinzira zihuza ibitekerezo bitandukanye, byorohereza itumanaho hagati yabo.Module ya I / O itanga intera kubikoresho byo hanze kugirango bikorane na FPGA.Iyi miterere ihindagurika cyane ituma abashushanya gukora sisitemu igoye ishobora guhindurwa byoroshye cyangwa ikongera ikandikwa.

Ibyiza bya FPGAs:
Inyungu nyamukuru ya FPGAs nuburyo bworoshye.Bitandukanye na porogaramu yihariye ihuriweho (ASICs), itoroshye kubikorwa byihariye, FPGAs irashobora guhindurwa ukundi nkuko bikenewe.Ibi bituma abashushanya gukora prototype byihuse, kugerageza no guhindura imirongo nta kiguzi cyo gukora ASIC yihariye.FPGAs itanga kandi ibihe bigufi byiterambere, bikagabanya igihe-ku isoko rya sisitemu ya elegitoroniki igoye.Byongeye kandi, FPGAs irasa cyane muri kamere, bigatuma ikoreshwa muburyo bwo kubara cyane nkubwenge bwubuhanga, kubika amakuru, no gutunganya ibimenyetso nyabyo.Byongeye kandi, FPGAs ikoresha ingufu nyinshi kuruta gutunganya-intego rusange kuko irashobora guhuzwa neza nigikorwa cyifuzwa, kugabanya ingufu zitari ngombwa.

Gusaba mu nganda zitandukanye:
Bitewe nuburyo bwinshi, FPGAs ikoreshwa mubikorwa bitandukanye.Mu itumanaho, FPGAs ikoreshwa muri sitasiyo fatizo hamwe nu murongo wa rezo yo gutunganya amakuru yihuta, kuzamura umutekano wamakuru, no gushyigikira imiyoboro isobanurwa na software.Muri sisitemu yimodoka, FPGAs ituma ubufasha bugezweho bwo gufasha abashoferi nko kwirinda kugongana no kugenzura imiterere yo guhuza n'imiterere.Zikoreshwa kandi mugutunganya amashusho-nyayo, gusuzuma no gukurikirana abarwayi mubikoresho byubuvuzi.Byongeye kandi, FPGAs ni ntangarugero mu kirere no mu birindiro, ikoresha sisitemu ya radar, indege, n’itumanaho ryizewe.Guhuza n'imiterere n'imikorere idasanzwe bituma FPGA igice cyingenzi cyikoranabuhanga rigezweho mubice bitandukanye.

Inzitizi n'icyerekezo kizaza:
Nubwo FPGAs ifite ibyiza byinshi, irerekana kandi ibibazo byabo bwite.Igishushanyo mbonera cya FPGA kirashobora kuba ingorabahizi, bisaba ubuhanga nubuhanga mu ndimi zisobanura ibyuma hamwe nubwubatsi bwa FPGA.Byongeye kandi, FPGAs ikoresha imbaraga zirenze ASIC mugihe ikora umurimo umwe.Nyamara, ubushakashatsi niterambere bikomeje gukemura ibyo bibazo.Hateguwe ibikoresho bishya nuburyo bworoshye kugirango byorohereze igishushanyo cya FPGA no kugabanya gukoresha ingufu.Mugihe ikoranabuhanga rikomeje gutera imbere, FPGAs ziteganijwe kurushaho gukomera, gukoresha ingufu, no kuboneka kubantu benshi bashushanya.

Mu gusoza:
Field Programmable Gate Arrays yahinduye umurima wububiko bwa sisitemu.Guhinduka kwabo, guhindurwa neza no guhuza byinshi bituma biba ingenzi mubikorwa bitandukanye.Kuva mu itumanaho kugera ku binyabiziga no mu kirere, FPGAs itanga imikorere igezweho kandi ikora neza.Nubwo hari ibibazo, gukomeza iterambere byizeza kubitsinda no kurushaho kunoza ubushobozi no gukoresha ibyo bikoresho bidasanzwe.Hamwe nogukenera gukenera sisitemu ya elegitoroniki igoye kandi yihariye, FPGAs ntagushidikanya izagira uruhare runini mugushiraho ejo hazaza hifashishijwe ibizunguruka.
