LFE5U-25F-6BG256C - Akabatanidzwa Masekete, Akaiswa, FPGAs (Field Programmable Gate Array)

FPGAs

suma:
Field Programmable Gate Arrays (FPGAs) yabuda seyepamusoro tekinoroji mudhijitari redunhu dhizaini.Aya anorongwa akasanganiswa maseketi anopa vagadziri vane kusati kwamboitika kuchinjika uye kugona kugadzirisa.Muchinyorwa chino, isu tinonyura munyika yeFPGAs, tichiongorora maitiro avo, mabhenefiti, uye mashandisiro.Nekunzwisisa kugona uye kugona kweFPGAs, tinogona kunzwisisa kuti vakashandura sei ndima yedhijitari yedunhu dhizaini.

Chimiro uye basa:
FPGAs anogadzirika edhijitari maseketi anogadzirwa neanorongeka logic mabhuroko, anobatana, uye ekuisa / kubuda (I/O) zvidhinha.Aya mabhuroki anogona kurongwa uchishandisa hardware tsananguro mutauro (HDL) seVHDL kana Verilog, zvichibvumira mugadziri kuti ataure basa redunhu.Logic blocks inogona kugadziridzwa kuti iite akasiyana mashandiro, senge arithmetic kuverenga kana logic mabasa, nekugadzira tafura yekutarisa (LUT) mukati meiyo logic block.Interconnects inoshanda semakwara anobatanidza akasiyana logic blocks, achifambisa kutaurirana pakati pavo.Iyo I/O module inopa chinongedzo chemidziyo yekunze yekudyidzana neFPGA.Ichi chimiro chinochinjika zvakanyanya chinoita kuti vagadziri vagadzire akaomarara edhijitari maseketi anogona kugadziridzwa kana kurongwa zvakare.

Zvakanakira zveFPGAs:
Mukana mukuru weFPGAs kuchinjika kwavo.Kusiyana neapplication-specific integrated circuits (ASICs), ayo akaomeswa kune chaiwo mabasa, maFPGA anogona kugadziridzwa zvakare sezvinodiwa.Izvi zvinobvumira vagadziri kukurumidza prototype, kuyedza uye kugadzirisa maseketi pasina muripo wekugadzira tsika ASIC.FPGAs inopawo mapfupi ekusimudzira denderedzwa, kuderedza nguva-ku-kumusika kune akaomarara emagetsi masisitimu.Pamusoro pezvo, maFPGA anoenderana zvakanyanya muchisikigo, achiita kuti ave akakodzera kune computationally yakadzika maapplication akadai sehungwaru hwekunyepedzera, encryption yedata, uye chaiyo-nguva chiratidzo chekugadzirisa.Pamusoro pezvo, maFPGA ane simba-rinoshanda pane zvakajairika-chinangwa processors nekuti anogona kunyatsogadzirirwa kune yaunoda mashandiro, kuderedza kushandiswa kwesimba kusingakoshi.

Zvikumbiro mumaindasitiri akasiyana:
Nekuda kwekusiyana-siyana kwavo, maFPGA anoshandiswa mumaindasitiri akasiyana.Mukufambiswa kwemashoko, maFPGA anoshandiswa muzviteshi zvepasi uye netiweki ma routers kugadzirisa yakakwirira-kumhanya data, kuwedzera kuchengetedzeka kwedata, uye kutsigira software-yakatsanangurwa network.Mune mota masisitimu, FPGAs inogonesa yepamberi yekubatsira mutyairi maficha akadai sekudzivirira kudhumhana uye inogadzirisa rwendo rwekufamba.Iwo zvakare anoshandiswa mune chaiyo-nguva yekugadzirisa mufananidzo, diagnostics uye kutarisa kwevarwere mumidziyo yekurapa.Pamusoro pezvo, maFPGA akakosha kune aerospace nekudzivirira maapplication, simba radar masisitimu, avionics, uye kutaurirana kwakachengeteka.Kuchinjika kwayo uye hunhu hwakasarudzika hwekuita hunoita kuti FPGA ive chikamu chakakosha chekucheka-kumucheto tekinoroji munzvimbo dzakasiyana siyana.

Zvinetso uye mafambiro emangwana:
Kunyangwe maFPGA aine akawanda mabhenefiti, ivo vanopawo yavo seti yezvinetso.Iyo FPGA dhizaini maitiro inogona kuve yakaoma, ichida hunyanzvi uye hunyanzvi mumitauro yekutsanangura Hardware uye FPGA yekuvaka.Pamusoro pezvo, maFPGA anoshandisa simba rakawanda kupfuura maASIC paanenge achiita basa rimwe chete.Nekudaro, kuenderera mberi kwekutsvagisa nekusimudzira kuri kugadzirisa matambudziko aya.Zvishandiso zvitsva uye nzira dziri kugadzirwa kurerutsa FPGA dhizaini uye kuderedza mashandisiro emagetsi.Sezvo tekinoroji ichiramba ichifambira mberi, maFPGA anotarisirwa kuve ane simba, akawedzera simba-anoshanda, uye kuwanikwa kune yakafararira yevagadziri.

Mukupedzisa:
Field Programmable Gate Arrays yakashandura munda wedhijitari wedunhu dhizaini.Kuchinjika kwavo, kugadzirisika uye kuita zvakasiyana-siyana kunoita kuti zvive zvakakosha mumaindasitiri akasiyana.Kubva panharembozha kuenda kumota uye aerospace, FPGAs inogonesa kushanda kwepamberi uye kuita kwepamusoro.Pasinei nematambudziko, kuenderera mberi kunovimbisa kuzvikunda uye kuwedzera hunyanzvi uye mashandisiro ezvishandiso izvi zvinoshamisa.Nekukura kuri kudiwa kweakaomesesa uye akajairika emagetsi masisitimu, maFPGA pasina mubvunzo achaita basa rakakosha mukugadzira ramangwana redhijitari redunhu dhizaini.
