XCVU9P-2FLGA2104I – IiSekethe eziDityanisiweyo, ziFakelwe, iiFPGAs (I-Field Programmable Gate Array)

Umgaqo wokusebenza:
Ii-FPGA zisebenzisa ingqikelelo efana ne-Logic Cell Array (LCA), engaphakathi ngaphakathi iqulathe amacandelo amathathu: iBloko yokuQiniseka okuQinisekayo (CLB), iBloko yokuPhuma iNgeniso (IOB) kunye noMdibaniso waNgaphakathi.I-Field Programmable Gate Arrays (FPGAs) zizixhobo ezicwangciswayo ezinolwakhiwo olwahlukileyo kuneesekethe zengqiqo zemveli kunye noluhlu lwamasango njenge PAL, GAL kunye nezixhobo zeCPLD.Ingqiqo yeFPGA iphunyezwa ngokulayisha iiseli zememori zangaphakathi kunye nedatha ecwangcisiweyo, amaxabiso agcinwe kwiiseli zememori amisela umsebenzi wengqiqo yeeseli zengqiqo kunye nendlela iimodyuli ezidityaniswe ngayo enye kwenye okanye kwi-I / O.Amaxabiso agcinwe kwiiseli zememori amisela umsebenzi onengqondo weeseli ezinengqondo kunye nendlela iimodyuli ezidityaniswe ngayo enye kwenye okanye kwi-I / Os, kwaye ekugqibeleni imisebenzi enokuthi iphunyezwe kwi-FPGA, evumela inkqubo engenamkhawulo. .

Uyilo lweChip:
Xa kuthelekiswa nolunye uhlobo loyilo lwetshiphu, umyinge ophezulu kunye noyilo olungqongqo ngakumbi ukuhamba okusisiseko kuyafuneka ngokuphathelene neetshiphusi zeFPGA.Ngokukodwa, uyilo kufuneka ludityaniswe ngokusondeleyo ne-FPGA schematic, evumela ubungakanani obukhulu boyilo lwe-chip ekhethekileyo.Ngokusebenzisa iMatlab kunye ne-algorithms yoyilo olukhethekileyo kwi-C, kufanele ukuba kwenzeke ukuphumeza inguqu egudileyo kuzo zonke iinkalo kwaye ngaloo ndlela iqinisekise ukuba ihambelana nokucinga koyilo lwe-chip oluqhelekileyo lwangoku.Ukuba ngaba kunjalo, ngoko ngokuqhelekileyo kuyimfuneko ukugxila ekudityanisweni okucwangcisiweyo kwamacandelo kunye nolwimi oluhambelanayo loyilo ukuze kuqinisekiswe i-chip design esebenzayo kunye nefundekayo.Ukusetyenziswa kwe-FPGAs kwenza ukuba ibhodi ihlaziywe, ikhowudi yokulinganisa kunye neminye imisebenzi yoyilo ehambelanayo ukuqinisekisa ukuba ikhowudi yangoku ibhalwe ngendlela kwaye isisombululo soyilo siyahlangabezana neemfuno ezithile zoyilo.Ukongeza koku, i-algorithms yoyilo kufuneka ibekwe phambili ukuze kuphuculwe uyilo lweprojekthi kunye nokusebenza kakuhle kwetshiphu.Njengomyili, inyathelo lokuqala kukwakha imodyuli ethile ye-algorithm apho ikhowudi ye-chip inxulumene khona.Oku kungenxa yokuba ikhowudi eyilwe kwangaphambili inceda ukuqinisekisa ukuthembeka kwe-algorithm kwaye ikhulisa kakhulu uyilo lwe-chip ngokubanzi.Ngokulungiswa kwebhodi epheleleyo kunye novavanyo lokulinganisa, kufuneka kwenzeke ukunciphisa ixesha lokujikeleza elichithwa ekuyileni i-chip yonke kumthombo kunye nokwandisa isakhiwo esipheleleyo se-hardware ekhoyo.Lo mzekelo omtsha woyilo lwemveliso uhlala usetyenziswa, umzekelo, xa uphuhlisa i-interfaces ye-hardware engekho kumgangatho.

Owona mngeni uphambili kuyilo lweFPGA kukuqhelana nenkqubo yehardware kunye nezibonelelo zayo zangaphakathi, ukuqinisekisa ukuba ulwimi loyilo luvumela ulungelelwaniso olusebenzayo lwamacandelo kunye nokuphucula ukufundeka kunye nokusetyenziswa kwenkqubo.Oku kukwabeka iimfuno eziphezulu kumyili, ofuna ukufumana amava kwiiprojekthi ezininzi ukuhlangabezana neemfuno.

 Uyilo lwe-algorithm kufuneka lugxininise kwingqiqo ukuze kuqinisekiswe ukugqitywa kokugqibela kweprojekthi, ukuphakamisa isisombululo kwingxaki esekelwe kwimeko yangempela yeprojekthi, kunye nokuphucula ukusebenza kakuhle kweFPGA.Emva kokumisela i-algorithm kufuneka ibe nengqiqo ukwakha imodyuli, ukuququzelela ukuyila ikhowudi kamva.Ikhowudi eyenziwe kwangaphambili ingasetyenziselwa ukuyila ikhowudi ukuphucula ukusebenza kakuhle kunye nokuthembeka.Ngokungafaniyo nee-ASICs, ii-FPGA zinomjikelo wophuhliso olufutshane kwaye zinokudityaniswa neemfuno zoyilo zokutshintsha ubume be-hardware, enokunceda iinkampani ziqalise iimveliso ezintsha ngokukhawuleza kwaye zihlangabezane neemfuno zophuhliso olungelulo oluqhelekileyo xa iiprotocol zonxibelelwano zingavuthwa.
