XCVU9P-2FLGA2104I - Imirongo ihuriweho, yashyizwemo, FPGAs (Field Programmable Gate Array)

Ihame ry'imikorere:
FPGAs ikoresha igitekerezo nka Logic Cell Array (LCA), imbere igizwe nibice bitatu: Configurable Logic Block (CLB), Ibisohoka Byinjira (IOB) hamwe na Imbere Imbere.Field Programmable Gate Arrays (FPGAs) nibikoresho byogushobora gukoreshwa hamwe nubwubatsi butandukanye nubwoko bwa logique gakondo hamwe n amarembo nkibikoresho bya PAL, GAL na CPLD.Logic ya FPGA ishyirwa mubikorwa mugupakira imbere muri selile yibuka ya selile hamwe na data programme, indangagaciro zibitswe muri selile yibuka zigena imikorere ya logique ya selile ya logique nuburyo modules zahujwe cyangwa kuri I / O.Indangagaciro zibitswe muri selile yibuka zigena imikorere yumvikana ya selile ya logique nuburyo modules zahujwe hagati yazo cyangwa na I / Os, hanyuma amaherezo imikorere ishobora gushyirwa mubikorwa muri FPGA, itanga progaramu itagira imipaka .

Igishushanyo mbonera:
Ugereranije nubundi bwoko bwibishushanyo mbonera, urwego rwo hejuru kandi rukomeye rwibanze rusanzwe rusabwa kubijyanye na chip ya FPGA.By'umwihariko, igishushanyo kigomba guhuzwa cyane nigishushanyo cya FPGA, cyemerera igipimo kinini cyibishushanyo bidasanzwe.Ukoresheje Matlab hamwe nigishushanyo cyihariye cya algorithms muri C, bigomba gushoboka kugera ku mpinduka nziza mubyerekezo byose bityo ukemeza ko bihuye nibitekerezo byibanze bya chip.Niba ibi aribyo, mubisanzwe birakenewe kwibanda kumurongo uhuza ibice hamwe nururimi rujyanye nigishushanyo kugirango tumenye neza chip ikoreshwa.Imikoreshereze ya FPGAs ituma ikibaho gikemurwa, kwigana kode hamwe nibindi bikorwa bijyanye nigishushanyo mbonera kugirango kode iriho yandike muburyo kandi igisubizo cyibishushanyo cyujuje ibyangombwa bisabwa.Usibye ibi, igishushanyo mbonera cya algorithms kigomba gushyirwa imbere kugirango tunonosore igishushanyo mbonera cyumushinga nibikorwa bya chip.Nkuwashushanyije, intambwe yambere nukubaka algorithm yihariye module ya chip code ifitanye isano.Ibi ni ukubera ko code yabanje gutegurwa ifasha kwemeza kwizerwa rya algorithm kandi igahindura neza igishushanyo mbonera cya chip.Hamwe nimikorere yuzuye yo kugerageza no kwigana, bigomba gushoboka kugabanya igihe cyigihe cyakoreshejwe mugushushanya chip yose aho ikomoka no kunoza imiterere rusange yibikoresho bihari.Ubu buryo bushya bwo gushushanya ibicuruzwa bukoreshwa kenshi, kurugero, mugihe utezimbere ibyuma bidasanzwe bisanzwe.

Ikibazo nyamukuru mubishushanyo bya FPGA nukumenyera sisitemu yibikoresho hamwe nibikoresho byayo imbere, kugirango ururimi rwigishushanyo rushoboze guhuza neza ibice no kunoza gusoma no gukoresha gahunda.Ibi kandi birasaba cyane uwashushanyije, ukeneye kunguka uburambe mumishinga myinshi kugirango yuzuze ibisabwa.

 Igishushanyo cya algorithm gikeneye kwibanda ku gushyira mu gaciro kugira ngo umushinga urangire, gutanga igisubizo ku kibazo ukurikije uko umushinga uhagaze, no kunoza imikorere ya FPGA.Nyuma yo kumenya algorithm igomba kuba ifite ishingiro yo kubaka module, kugirango yorohereze code nyuma.Kode yabanjirije irashobora gukoreshwa mugushushanya kode kugirango tunoze imikorere kandi yizewe.Bitandukanye na ASICs, FPGAs ifite uruzinduko rugufi rwiterambere kandi irashobora guhuzwa nibisabwa kugirango uhindure imiterere yibyuma, bishobora gufasha ibigo gutangiza ibicuruzwa bishya vuba kandi bigahuza ibikenewe byiterambere ryimikorere idasanzwe mugihe protocole yitumanaho idakuze.
