XCVU9P-2FLGA2104I - Haɗaɗɗen kewayawa, Haɗe-haɗe, FPGAs (Tsarin Ƙofar Ƙofar Mai Shiryewa)

Ka'idar aiki:
FPGAs suna amfani da ra'ayi kamar Logic Cell Array (LCA), wanda a ciki ya ƙunshi sassa uku: Configurable Logic Block (CLB), Block Output Block (IOB) da Interconnect Interconnect.Filin Programmable Gate Arrays (FPGAs) na'urori ne masu shirye-shirye tare da gine-gine daban-daban fiye da da'irar dabaru na gargajiya da tsararrun ƙofa kamar na'urorin PAL, GAL da CPLD.Ana aiwatar da ma'anar FPGA ta hanyar loda ƙwayoyin ƙwaƙwalwar ajiya na ciki tare da bayanan da aka tsara, ƙimar da aka adana a cikin sel ƙwaƙwalwar ajiya sun ƙayyade aikin tunani na sel dabaru da kuma hanyar da aka haɗa samfuran zuwa juna ko zuwa I / O.Ƙimar da aka adana a cikin ƙwayoyin ƙwaƙwalwar ajiya suna ƙayyade aikin ma'ana na sel masu hankali da kuma hanyar da aka haɗa nau'ikan zuwa juna ko zuwa I / Os, kuma a ƙarshe ayyukan da za a iya aiwatarwa a cikin FPGA, wanda ke ba da damar tsara shirye-shirye marasa iyaka. .

Tsarin guntu:
Idan aka kwatanta da sauran nau'ikan ƙirar guntu, mafi girma kofa da ƙarin ƙaƙƙarfan kwararar ƙira yawanci ana buƙata game da guntuwar FPGA.Musamman ma, ƙirar ya kamata a haɗa ta kut da kut da tsarin FPGA, wanda ke ba da damar girman sikelin ƙirar guntu na musamman.Ta amfani da Matlab da algorithms ƙira na musamman a cikin C, ya kamata a sami damar samun sauyi mai sauƙi a duk kwatance kuma don haka tabbatar da cewa ya dace da tunanin ƙirar guntu na yau da kullun.Idan haka ne, to yawanci ya zama dole a mai da hankali kan tsarin haɗin kai na abubuwan haɗin gwiwa da harshen ƙirar da ya dace don tabbatar da ƙirar guntu mai amfani da karantawa.Yin amfani da FPGAs yana ba da damar gyara allon allo, simulation code da sauran ayyukan ƙira masu alaƙa don tabbatar da cewa an rubuta lambar yanzu ta hanya kuma cewa ƙirar ƙirar ta cika ƙayyadaddun buƙatun ƙira.Baya ga wannan, ya kamata a ba da fifikon ƙirar ƙirar ƙira don haɓaka ƙirar aikin da tasirin aikin guntu.A matsayin mai ƙira, mataki na farko shine gina ƙayyadaddun ƙirar algorithm wanda lambar guntu ke da alaƙa.Wannan saboda lambar da aka riga aka tsara tana taimakawa don tabbatar da amincin algorithm kuma yana haɓaka ƙirar guntu gabaɗaya.Tare da cikakken gyaran allo da gwajin kwaikwaiyo, yakamata a rage lokacin sake zagayowar da ake cinyewa wajen zayyana guntu gabaɗaya a tushe kuma don haɓaka tsarin gaba ɗaya na kayan aikin da ke akwai.Ana amfani da wannan sabon ƙirar ƙirar samfuri sau da yawa, misali, lokacin haɓaka mu'amalar kayan masarufi marasa daidaituwa.

Babban ƙalubale a cikin ƙirar FPGA shine sanin tsarin kayan masarufi da albarkatun cikinsa, don tabbatar da cewa yaren ƙira yana ba da damar haɗin kai mai inganci da haɓaka haɓakawa da amfani da shirin.Wannan kuma yana sanya manyan buƙatu akan mai zane, wanda ke buƙatar samun gogewa a cikin ayyukan da yawa don biyan buƙatun.

 Tsarin algorithm yana buƙatar mayar da hankali kan hankali don tabbatar da kammala aikin ƙarshe, don ba da shawarar warware matsalar dangane da ainihin yanayin aikin, da haɓaka ingantaccen aikin FPGA.Bayan kayyade algorithm ya zama m don gina module, don sauƙaƙe ƙirar ƙira daga baya.Ana iya amfani da lambar da aka riga aka ƙera a ƙirar lambar don inganta inganci da aminci.Ba kamar ASICs ba, FPGAs suna da ɗan gajeren zagaye na ci gaba kuma ana iya haɗa su tare da buƙatun ƙira don canza tsarin kayan aikin, wanda zai iya taimaka wa kamfanoni su ƙaddamar da sababbin samfurori da sauri da kuma biyan bukatun ci gaba na rashin daidaituwa lokacin da ka'idojin sadarwa ba su da girma.
