Intshayelelo
Uluhlu lwesango olucwangcisiweyo lommandla, oluyimveliso yophuhliso olongezelelweyo kwisiseko sezixhobo ezicwangcisiweyo ezifana nePAL, GAL, CPLD njalo njalo.Kubonakala njengesekethe ye-semi-custom kwintsimi ye-application-specific integrated circuits (ASICs), engasombululi kuphela iziphene zeesekethe zesiko, kodwa ziphinde zoyise iintsilelo zenani elilinganiselweyo leesekethe zesango zesixhobo sokuqala.
Umgaqo wokuSebenza
I-FPGA ithatha ingcamango entsha ye-logic cell array LCA (Logic Cell Array), equka iindawo ezintathu: imodyuli ye-logic eqwalaselweyo ye-CLB, imodyuli yegalelo lemveliso ye-IOB (i-Input Output Block) kunye noxhulumaniso lwangaphakathi (I-Interconnect).Iimpawu ezisisiseko zeeFPGA zezi:
I-1) Ukusebenzisa i-FPGA ukuyila iisekethe ze-ASIC, abasebenzisi abafuni ukuvelisa i-chips ukufumana i-chip efanelekileyo.
2) I-FPGA ingasetyenziswa njengomzekelo wokulingwa wezinye iisekethe ze-ASIC ezilungiselelwe ngokupheleleyo okanye ezilungelelanisiweyo.
3) I-FPGA inobutyebi be-flip-flops kunye ne-I / O izikhonkwane ngaphakathi.
I-4) I-FPGA yenye yezixhobo ezinomjikelezo omncinci woyilo, ixabiso eliphantsi lophuhliso kunye nomngcipheko ophantsi kwisekethe ye-ASIC.
I-5) I-FPGA ithatha inkqubo ye-CHMOS yesantya esiphezulu, ukusetyenziswa kwamandla aphantsi, kwaye inokuhambelana namanqanaba e-CMOS kunye ne-TTL.
Kunokuthiwa iitshiphusi zeFPGA lolunye lolona khetho lungcono kwiinkqubo zebhetshi ezincinci zokuphucula ukudityaniswa kwenkqubo kunye nokuthembeka.
I-FPGA icwangciswe yinkqubo egcinwe kwi-RAM kwi-chip ukuseta imeko yayo yokusebenza, ngoko ke i-RAM ekwi-chip kufuneka icwangciswe xa isebenza.Abasebenzisi banokusebenzisa iindlela ezahlukeneyo zokucwangcisa ngokweendlela ezahlukeneyo zoqwalaselo.
Xa umbane, i-chip ye-FPGA ifunda idatha kwi-EPROM kwi-RAM yeprogram ye-chip, kwaye emva kokuba uqwalaselo lugqityiwe, i-FPGA ingena kwindawo yokusebenza.Emva kokuba amandla elahlekile, i-FPGA ibuyela kumaphepha amhlophe, kwaye ubudlelwane obunengqondo bangaphakathi buyanyamalala, ngoko i-FPGA ingasetyenziselwa ngokuphindaphindiweyo.Inkqubo yeFPGA ayifuni umdwelisi weFPGA ozinikeleyo, kuphela i-EPROM yenjongo jikelele kunye nomdwelisi we-PROM.Xa ufuna ukulungisa umsebenzi weFPGA, vele utshintshe i-EPROM.Ngale ndlela, i-FPGA efanayo, idatha yeprogram eyahlukeneyo, inokuvelisa imisebenzi eyahlukeneyo yesiphaluka.Ke ngoko, ukusetyenziswa kweeFPGAs kubhetyebhetye kakhulu.
Iindlela zoqwalaselo
I-FPGA ineendlela ezahlukeneyo zoqwalaselo: indlela ephambili ehambelanayo yiFPGA kunye neEPROM;Imowudi ye-master-slave inokuxhasa inkqubo enye ye-PIECE PROM ezininzi zeFPGA;Imowudi yothotho inokucwangciswa ngothotho lwe-PROM FPGA;Imowudi yeperipheral ivumela iFPGA ukuba isetyenziswe njenge peripheral ye microprocessor, ecwangciswe yi microprocessor.
Imiba enjengokufezekisa ukuvalwa kwexesha ngokukhawuleza, ukunciphisa ukusetyenziswa kwamandla kunye neendleko, ukuphucula ulawulo lwewotshi, kunye nokunciphisa ubunzima beFPGA kunye noyilo lwePCB bekusoloko kuyimiba ephambili kwiinjineli zoyilo lwenkqubo ezisebenzisa iiFPGAs.Namhlanje, njengoko iiFPGA zisiya kuxinaniso oluphezulu, umthamo omkhulu, ukusetyenziswa kwamandla aphantsi, kunye nokudityaniswa kwe-IP, iinjineli zoyilo lwenkqubo ziyazuza kule ntsebenzo iphezulu ngelixa zijongene nemingeni emitsha yoyilo ngenxa yamanqanaba angazange abonwe ngaphambili okusebenza kunye nokukwazi kweFPGAs.
