I-XC7K420T-2FFG901I-IiSekethe eziDityanisiweyo, eziThunyelelweyo, iiNdawo zeSango eziLungiselwayo

Iingenelo
Izinto eziluncedo kwiiFPGA zezi zilandelayo:
(1) Ii-FPGA zibandakanya izixhobo ze-hardware ezifana neeseli ze-logic, i-RAM, i-multipliers, njl. Ngokucwangcisa ezi zixhobo ze-hardware ngokufanelekileyo, iisekethe ze-hardware ezifana neziphindaphinda, iirejista, ii-generator idilesi, njl.
(2) Ii-FPGA zinokuthi ziyilwe ngokusebenzisa imizobo yebhloko okanye i-Verilog HDL, ukusuka kwiisekethe zesango ezilula ukuya kwiisekethe ze-FIR okanye ze-FFT.
(3) Ii-FPGA zinokuphinda zicwangciswe ngokungenasiphelo, zilayishe isisombululo esitsha sokuyila kwii-milliseconds ezingamakhulu ambalwa, zisebenzisa ukulungiswa kwakhona ukunciphisa i-hardware ephezulu.
(4) I-frequency yokusebenza ye-FPGA igqitywe yi-chip ye-FPGA kunye noyilo, kwaye inokuguqulwa okanye itshintshwe nge-chip ekhawulezayo ukuhlangabezana neemfuno ezithile ezifunwayo (nangona, ngokuqinisekileyo, ukusebenza rhoqo akunasiphelo kwaye kunoko. yandiswe, kodwa ilawulwa ziinkqubo zangoku ze-IC kunye nezinye izinto).
Iingxaki
Ukungalungi kweeFPGA zezi zilandelayo:
(1) Ii-FPGA zithembele ekuphunyezweni kwe-hardware kuyo yonke imisebenzi kwaye ayikwazi ukuphumeza imisebenzi efana ne-branching conditional jumps.
(2) Ii-FPGAs zinokwenza kuphela imisebenzi yeendawo ezisisigxina.
Isishwankathelo: I-FPGAs ixhomekeke kwi-hardware ukuphumeza yonke imisebenzi kwaye inokuthelekiswa neetshiphusi ezizinikeleyo ngokwesantya, kodwa kukho i-gap enkulu kwi-design flexibility xa kuthelekiswa neeprosesa zenjongo ngokubanzi.

Yila iilwimi kunye namaqonga

Izixhobo ezicwangcisiweyo zengqiqo ngabathwali be-hardware ezenza imisebenzi emiselweyo kunye neenkcukacha zobugcisa bezicelo ze-elektroniki ngeteknoloji ye-EDA.Ii-FPGA, njengenye yezixhobo eziphambili eziphumeza le ndlela, zijolise kumsebenzisi ngokuthe ngqo, zibhetyebhetye kakhulu kwaye ziguquguquka, kulula ukuyisebenzisa, kwaye ziyakhawuleza ukuvavanya kunye nokuphunyezwa kwihardware.
Inkcazo ye-Hardware Ulwimi (i-HDL) lulwimi olusetyenziselwa ukuyila iinkqubo ze-digital logic kunye nokuchaza iisekethe zedijithali, ezona zisetyenziswa ngokuqhelekileyo yiVHDL, i-Verilog HDL, i-System Verilog kunye ne-System C.
Njengolwimi lwenkcazo ye-hardware ejikelezayo yonke, i-Speed ​​​​High Speed ​​​​Integrated Circuit Hardware Description Language (VHDL) ineempawu zokuzimela kwisekethe ethile ye-hardware kunye nokuzimela kwiqonga lokuyila, kunye neenzuzo zobuchule bokuchaza uluhlu olubanzi, hayi. ixhomekeke kwizixhobo ezithile, kunye nokukwazi ukuchaza uyilo lwengqiqo yolawulo olunzima kwikhowudi engqongqo kunye nefutshane, njl.esetyenziswa ngokubanzi.
I-VHDL lulwimi olukwinqanaba eliphezulu loyilo lwesekethe, kwaye xa kuthelekiswa nezinye iilwimi zenkcazo ye-hardware, ineempawu zolwimi olulula, ukuguquguquka kunye nokuzimela kuyilo lwesixhobo, okwenza kube lulwimi oluqhelekileyo lwenkcazo ye-hardware ye-teknoloji ye-EDA kunye nokwenza iteknoloji ye-EDA ngakumbi. ifikeleleke kubayili.
I-HDL ye-Verilog lulwimi lwenkcazo ye-hardware esetyenziswa ngokubanzi enokusetyenziswa kwizigaba ezininzi zenkqubo yoyilo lwe-hardware, kubandakanywa imodeli, i-synthesis kunye nokulinganisa.
I-Verilog HDL i-Advantages: ifana ne-C, kulula ukufunda kwaye iguquguqukayo.Case sensitive.Izinto eziluncedo ekubhaleni uvuselelo kunye nokwenza imodeli.Ukungalungi: iimpazamo ezininzi azinakubonwa ngexesha lokuqokelela.
IiPros ze-VHDL: I-syntax engqongqo, i-hierarchy ecacileyo.Ukungalungi: ixesha elide lokuqhelanisa, aliguquki ngokwaneleyo.
Isoftware ye-Quartus_II yimeko-bume yoyilo olupheleleyo lweplatform ephuhliswe yi-Altera, enokwanelisa iimfuno zoyilo lwee-FPGAs ezahlukeneyo kunye nee-CPLDs, kwaye yindawo ebanzi yoyilo lwenkqubo enokucwangciswa kwi-chip.
I-Vivado Design Suite, indawo edibeneyo yoyilo ekhutshwe ngumthengisi we-FPGA u-Xilinx kwi-2012. Iquka indawo yoyilo oludityanisiweyo kakhulu kunye nesizukulwana esitsha sezixhobo ukusuka kwinkqubo ukuya kwinqanaba le-IC, zonke ezakhelwe kwimodeli yedatha edibeneyo ekwabelwana ngayo kunye nommandla oqhelekileyo wokulungisa umonakalo.i-Xilinx Vivado Design Suite ibonelela nge-FIFO IP cores enokusetyenziswa ngokulula kuyilo.
