XC7K420T-2FFG901I - Masekete Akabatanidzwa, Akamisikidzwa, Munda Anorongwa Gedhi Arrays

Zvakanakira
Zvakanakira zveFPGAs ndeizvi:
(1) FPGAs dzinosanganisira hardware zviwanikwa zvakadai logic masero, RAM, multipliers, etc. Nekuronga izvi hardware zviwanikwa rationally, hardware circuits akadai multipliers, marejista, kero jenareta, etc. anogona kuitwa.
(2) MaFPGA anogona kugadzirwa nekushandisa block diagram kana Verilog HDL, kubva nyore gedhi maseketi kuenda kuFIR kana FFT maseketi.
(3) MaFPGA anogona kurongedzerwa zvachose, kurodha mhinduro nyowani mumazana mashoma emamilliseconds, uchishandisa reconfiguration kuderedza hardware pamusoro.
(4) Iyo yekushanda frequency yeFPGA inotarwa neiyo FPGA chip pamwe nedhizaini, uye inogona kugadziridzwa kana kutsiviwa nekasira chip kuti isangane nezvimwe zvinodiwa zvinodiwa (kunyangwe, hongu, iyo frequency yekushandisa haina magumo uye inogona. kuwedzera, asi inotongwa nezvino IC maitiro uye zvimwe zvinhu).
Zvakaipa
Izvo zvisingabatsiri zveFPGAs ndezvizvi:
(1) FPGAs inotsamira pakuitwa kwehardware kune ese mabasa uye haigone kuita mashandiro senge branching conditional jumps.
(2) FPGAs inogona chete kuita yakatarwa-point mashandiro.
Muchidimbu: maFPGA anovimba nehardware kuita mabasa ese uye anogona kufananidzwa nemachipi akazvitsaurira maererano nekumhanya, asi pane gaka rakakura mukugadzirisa dhizaini kana ichienzaniswa neyakajairwa chinangwa processors.

Gadzira mitauro nemapuratifomu

Programmable logic madivayiri vatakuri vehardware vanogadzira iyo yakamiswa mabasa uye tekinoroji maratidziro ezvemagetsi maapplication kuburikidza neEDA tekinoroji.FPGAs, seimwe yemidziyo mikuru inoshandisa nzira iyi, yakanangana nevashandisi, inochinjika zvakanyanya uye inochinja-chinja, iri nyore kushandisa, uye inokurumidza kuyedza nekushandisa muhardware.
Hardware Tsanangudzo Mutauro (HDL) mutauro unoshandiswa kugadzira madhijitari logic masisitimu uye kutsanangura maseketi edhijitari, iwo makuru anowanzo shandiswa VHDL, Verilog HDL, System Verilog uye System C.
Semutauro wekutsanangura wehardware, iyo Yakanyanya High Speed ​​​​Yakabatanidzwa Circuit Hardware Tsanangudzo Mutauro (VHDL) ine hunhu hwekuzvimiririra kune chaiyo hardware wedunhu uye yakazvimiririra yepuratifomu yekugadzira, ine zvakanakira zvekugona kutsanangura kwakakura, kwete. zvinoenderana nemichina chaiyo, uye kukwanisa kutsanangura kugadzirwa kwemaitiro akaomarara ekutonga mukodhi yakasimba uye yakapfupika, etc. Inotsigirwa nemakambani mazhinji eEDA uye yakashandiswa zvakanyanya mumunda wekugadzira magetsi.kushandiswa zvakanyanya.
VHDL mutauro wepamusoro-soro wekugadzirwa kwedunhu, uye kana ichienzaniswa nemimwe mitauro yetsanangudzo yehardware, ine hunhu hwemutauro wakapfava, kuchinjika uye kuzvimiririra kubva kudhizaini yedhizaini, zvichiita kuti ive yakajairika rondedzero yehardware mutauro weiyo EDA tekinoroji uye kuita EDA tekinoroji. inowanikwa kune vanogadzira.
Verilog HDL mutauro wekutsanangura wehardware unoshandiswa zvakanyanya unogona kushandiswa mumatanho akati wandei eiyo Hardware dhizaini maitiro, kusanganisira modhi, synthesis uye simulation.
Verilog HDL Advantages: yakafanana neC, iri nyore kudzidza uye inochinjika.Case-sensitive.Zvakanakira kunyora kukurudzira uye kuenzanisira.Zvakaipa: zvikanganiso zvakawanda hazvigone kuonekwa panguva yekuunganidza.
VHDL Pros: Yakasimba syntax, yakajeka hierarchy.Zvakaipa: nguva yakareba yekuziva, isingachinjiki zvakakwana.
Quartus_II software ndeye yakazara-multi-platform dhizaini nharaunda yakagadziridzwa neAltera, inogona kusangana nezvinodiwa zvekugadzira zveakasiyana FPGAs uye CPLDs, uye inzvimbo yakazara yeon-chip programmable system dhizaini.
Vivado Design Suite, yakasanganiswa dhizaini nharaunda yakabudiswa neFPGA mutengesi Xilinx muna 2012. Inosanganisira yakanyatsobatanidzwa dhizaini mamiriro uye chizvarwa chitsva chezvishandiso kubva kuhurongwa kusvika kuIC level, zvese zvakavakwa pane yakagovaniswa scalable data model uye inowanzoitika debug nharaunda.iyo Xilinx Vivado Dhizaini Suite inopa FIFO IP cores inogona kuiswa nyore kune madhizaini.
