I-XCVU9P-2FLGA2104I – Izifunda Ezihlanganisiwe, Ezishumekiwe, ama-FPGA (I-Field Programmable Gate Array)

Isimiso sokusebenza:
Ama-FPGA asebenzisa umqondo ofana ne-Logic Cell Array (LCA), ngaphakathi equkethe izingxenye ezintathu: I-Configurable Logic Block (CLB), I-Input Output Block (IOB) kanye Noxhumano Lwangaphakathi.I-Field Programmable Gate Arrays (ama-FPGA) angamadivayisi ahlelekayo anesakhiwo esihlukile kunesekhethi yengqondo yendabuko kanye namalungu afanayo amasango afana namadivayisi e-PAL, GAL kanye ne-CPLD.I-logic ye-FPGA isetshenziswa ngokulayisha amaseli ememori amile angaphakathi anedatha ehleliwe, amanani agcinwe kumaseli enkumbulo anquma umsebenzi onengqondo wamaseli anengqondo kanye nendlela amamojula axhumeke ngayo kwelinye noma ku-I/ O.Amanani agcinwe kumaseli enkumbulo anquma ukusebenza okunengqondo kwamaseli anengqondo kanye nendlela amamojula axhunywe ngayo kwamanye noma kuma-I/O, futhi ekugcineni imisebenzi engenziwa ku-FPGA, evumela ukuhlela okungenamkhawulo. .

Idizayini ye-chip:
Uma kuqhathaniswa nezinye izinhlobo zokwakheka kwe-chip, umkhawulo ophakeme kanye nokugeleza kwedizayini okuqinile ngokuvamile kuyadingeka mayelana nama-chips e-FPGA.Ikakhulukazi, umklamo kufanele uxhunywe eduze nohlelo lwe-FPGA, oluvumela isilinganiso esikhulu somklamo we-chip okhethekile.Ngokusebenzisa i-Matlab nama-algorithms edizayini akhethekile ku-C, kufanele kwenzeke ukuzuza uguquko olushelelayo kuzo zonke izinhlangothi futhi ngaleyo ndlela kuqinisekiswe ukuthi kuhambisana nokucabanga kwamanje komklamo we-chip ovamile.Uma kunjalo, khona-ke ngokuvamile kuyadingeka ukugxila ekuhlanganisweni okuhlelekile kwezingxenye kanye nolimi oluhambisanayo lokuklama ukuze kuqinisekiswe umklamo we-chip osebenzisekayo nofundekayo.Ukusetshenziswa kwama-FPGA kwenza ukulungisa amaphutha ebhodini, ukulingisa ikhodi kanye neminye imisebenzi yokuklama ehlobene ukuze kuqinisekiswe ukuthi ikhodi yamanje ibhalwe ngendlela nokuthi isisombululo sokuklama sihlangabezana nezidingo ezithile zokuklama.Ngaphezu kwalokhu, ama-algorithms wokuklama kufanele abekwe eqhulwini ukuze kuthuthukiswe umklamo wephrojekthi kanye nempumelelo yokusebenza kwe-chip.Njengomklami, isinyathelo sokuqala ukwakha imojula ethile ye-algorithm lapho ikhodi ye-chip ihlobene khona.Lokhu kungenxa yokuthi ikhodi eklanywe kusengaphambili isiza ukuqinisekisa ukwethembeka kwe-algorithm futhi ithuthukisa ngokuphawulekayo idizayini ye-chip iyonke.Ngokulungiswa okugcwele kwebhodi nokuhlolwa kokulingisa, kufanele kwenzeke ukunciphisa isikhathi somjikelezo esisetshenziswa ekudizayineni yonke i-chip emthonjeni kanye nokuthuthukisa sonke isakhiwo sehadiwe ekhona.Le modeli yomklamo omusha womkhiqizo ivame ukusetshenziswa, isibonelo, lapho kwakhiwa ukuxhumana kwehadiwe okungajwayelekile.

Inselele enkulu ekwakhiweni kwe-FPGA iwukujwayelana nesistimu yehadiwe kanye nezinsiza zayo zangaphakathi, ukuqinisekisa ukuthi ulimi lokuklama luvumela ukuhlanganiswa okusebenzayo kwezingxenye kanye nokwenza ngcono ukufundeka nokusetshenziswa kohlelo.Lokhu futhi kubeka izidingo eziphezulu kumklami, odinga ukuthola ulwazi kumaphrojekthi amaningi ukuze ahlangabezane nezidingo.

 Umklamo we-algorithm udinga ukugxila ekucabangeni ukuze kuqinisekiswe ukuphothulwa kokugcina kwephrojekthi, ukuphakamisa isisombululo senkinga ngokusekelwe esimweni sangempela sephrojekthi, kanye nokwenza ngcono ukusebenza kahle komsebenzi we-FPGA.Ngemuva kokunquma i-algorithm kufanele ibe nengqondo ukwakha imojuli, ukwenza lula ukwakheka kwekhodi kamuva.Ikhodi eklanywe kusengaphambili ingasetshenziswa ekwakhiweni kwekhodi ukuthuthukisa ukusebenza kahle nokuthembeka.Ngokungafani nama-ASIC, ama-FPGA anomjikelezo wokuthuthuka omfushane futhi angahlanganiswa nezidingo zokuklama ukuze kushintshwe ukwakheka kwehadiwe, okungasiza izinkampani ukuthi ziqalise imikhiqizo emisha ngokushesha futhi zihlangabezane nezidingo zokuthuthukiswa kokusebenzelana okungajwayelekile lapho izivumelwano zokuxhumana zingavuthiwe.
