Hordhac
Array gate programmable field, kaas oo ah maxsuulka horumarka dheeraadka ah ee ku salaysan aaladaha barnaamijyada sida PAL, GAL, CPLD iyo wixii la mid ah.Waxay u muuqataa sida wareegga semi-caadada ah ee berrinka codsiyada-gaar ah ee isku-dhafan ee isku-dhafan (ASICs), taas oo aan xallinaynin oo keliya cilladaha wareegyada caadada ah, laakiin sidoo kale waxay ka gudubtaa cilladaha tirada xaddidan ee qalabka asalka ah ee barnaamijyada albaabbada.
Mabda'a Shaqada
FPGA waxay qabataa fikrad cusub oo ah unug caqli gal ah array LCA (Logic Cell Array), oo ay ku jiraan saddex qaybood: module macquulka ah ee CLB, wax soo saarka moduleka IOB (Input Output Block) iyo xidhiidhka gudaha (Interconnect).Tilmaamaha aasaasiga ah ee FPGAs waa:
1) Isticmaalka FPGA si loo naqshadeeyo wareegyada ASIC, isticmaalayaashu uma baahna inay soo saaraan jajabyo si ay u helaan jajab ku habboon.
2) FPGA waxa loo isticmaali karaa tijaabo tijaabo ah oo ah wareegyada ASIC si buuxda loo habeeyey ama badh ahaan loo habeeyey.
3) FPGA waxay leedahay qani badan oo flip-flops ah iyo biinanka I/O gudaha.
4) FPGA waa mid ka mid ah aaladaha leh wareegga naqshadeynta ugu gaaban, kharashka horumarinta ugu hooseeya iyo khatarta ugu yar ee wareegga ASIC.
5) FPGA waxay qabataa habka CHMOS-xawaaraha sarreeya, isticmaalka tamarta yar, waxayna la jaan qaadi kartaa heerarka CMOS iyo TTL.
Waxaa la dhihi karaa chips-yada FPGA waa mid ka mid ah xulashooyinka ugu wanaagsan ee nidaamyada dufcadda yar si loo hagaajiyo isdhexgalka nidaamka iyo isku halaynta.
FPGA waxa lagu habeeyaa barnaamij lagu kaydiyay RAM-ka ku dul saaran si uu u dejiyo xaalada uu ku shaqaynayo, sidaa awgeed RAM-ku waxa uu u baahan yahay in la habeeyo marka uu shaqaynayo.Isticmaalayaashu waxay isticmaali karaan habab barnaamij oo kala duwan iyadoo loo eegayo qaababka qaabeynta ee kala duwan.
Marka la shido, FPGA-gu wuxuu akhriyaa xogta EPROM-ka barnaamijka RAM-ka, ka dib marka qaabeynta la dhammeeyo, FPGA waxay gashaa gobolka shaqada.Ka dib markii ay korontadu lunto, FPGA waxay ku soo noqotaa xaashida cadcad, xiriirka macquulka ah ee gudahana wuu baaba'aa, sidaas darteed FPGA waa la isticmaali karaa si isdaba joog ah.Barnaamijyada FPGA uma baahna barnaamij FPGA u go'an, kaliya barnaamijka EPROM iyo PROM-ujeeddada guud.Marka aad u baahan tahay inaad wax ka beddesho shaqada FPGA, kaliya beddel EPROM-ka.Sidan, FPGA isku mid ah, xogta barnaamijyada kala duwan, waxay soo saari kartaa hawlaha wareegga kala duwan.Sidaa darteed, isticmaalka FPGAs waa mid aad u dabacsan.
Hababka Habaynta
FPGA waxay leedahay habab habayn oo kala duwan: qaabka ugu muhiimsan ee isbarbar socda waa FPGA iyo EPROM;Habka addoonsiga wuxuu taageeri karaa hal PIECE PROM barnaamijka FPGAs badan;Qaabka taxanaha ah waxa lagu barnaamijayn karaa taxane PROM FPGA ah;Qaabka durugsan wuxuu u oggolaanayaa FPGA in loo isticmaalo sidii goob-xirfadeedka microprocessor-ka, oo uu habeeyey microprocessor-ka.
Arrimaha ay ka midka yihiin gaaritaanka xiritaanka degdegga ah, yareynta isticmaalka tamarta iyo qiimaha, hagaajinta maamulka saacadaha, iyo yareynta kakanaanta naqshadaha FPGA iyo PCB ayaa had iyo jeer ahaa arrimaha muhiimka ah ee injineerada naqshadeynta nidaamka isticmaalaya FPGAs.Maanta, sida FPGA-yadu u socdaan cufnaanta sare, awoodda weyn, isticmaalka awoodda hoose, iyo is dhexgalka IP badan, injineerada naqshadeynta nidaamka waxay ka faa'iideysanayaan bandhigyadan sare iyagoo wajahaya caqabado cusub oo naqshadeynta sababtoo ah heerarka waxqabadka iyo kartida FPGAs ee aan horay loo arag.
