Inkqubo yokwahlula ividiyo
Kwiminyaka yakutshanje, iinkqubo ezinkulu zolawulo zizonke ziye zasetyenziswa ngokubanzi ngokubanzi, kwaye inqanaba letekhnoloji yokwahlulahlula ividiyo ehambelana nazo iyaphucuka ngokuthe ngcembe, itekhnoloji ibekwe kunye nomboniso odityanisiweyo onezikrini ezininzi ukubonisa isiginali yevidiyo kuyo yonke indlela. abanye bafuna ukusebenzisa umboniso omkhulu weskrini osetyenziswa ngokubanzi.
Ngenkqubela phambili yetekhnoloji, itekhnoloji yokwahlulwa kwevidiyo ngokuthe ngcembe ikhule ukuze ihlangabezane neemfuno ezisisiseko zabantu kwimifanekiso yevidiyo ecacileyo, i-FPGA chip yesakhiwo se-hardware ikhethekileyo, ungasebenzisa ifayile yesakhiwo se-logic ehleliweyo ukulungelelanisa ubume bangaphakathi, ukusetyenziswa. yeefayile ezithintelweyo ukulungelelanisa uxhulumaniso kunye nendawo yeeyunithi zengqiqo ezahlukeneyo, ukuphathwa ngokufanelekileyo kwendlela yomgca wedatha, ukuguquguquka kwayo kunye nokulungelelaniswa ukuze kube lula ukulungelelanisa komsebenzisi Ukuguquguquka kwayo kunye nokulungelelanisa kuququzelela uphuhliso lomsebenzisi kunye nesicelo.Xa kusetyenzwa imiqondiso yevidiyo, i-chip ye-FPGA inokusebenzisa ngokupheleleyo isantya kunye nesakhiwo sayo ukuphumeza iindlela ze-ping-pong kunye nemibhobho.Kwinkqubo yoxhulumaniso lwangaphandle, i-chip isebenzisa uxhulumaniso oluhambelanayo lwedatha ukwandisa ububanzi be-bit yolwazi lomfanekiso kwaye isebenzise imisebenzi yengqiqo yangaphakathi ukunyusa isantya sokulungiswa komfanekiso.Ukulawulwa kokulungiswa komfanekiso kunye nezinye izixhobo kufezekiswa ngokusebenzisa izakhiwo ze-cache kunye nolawulo lwewotshi.I-chip ye-FPGA isentliziyweni yesakhiwo soyilo jikelele, i-interpolating data eyinkimbinkimbi kunye nokukhupha kunye nokugcinwa kwayo, kwaye idlala indima ekulawuleni ngokubanzi ukuqinisekisa ukusebenza okuzinzileyo kwenkqubo.Ukongeza, ukucutshungulwa kolwazi lwevidiyo kwahlukile kolunye ukusetyenzwa kwedatha kwaye kufuna ukuba i-chip ibe neeyunithi ezikhethekileyo ze-logic kunye ne-RAM okanye iiyunithi ze-FIFO zokuqinisekisa ukuba isantya esaneleyo sokuhanjiswa kwedatha siyenyuka.

Abalibazisi beDatha kunye noYilo loGcino
Ii-FPGA zineeyunithi zokulibaziseka ezicwangcisiweyo zedijithali kwaye zinoluhlu olubanzi lwezicelo kwiinkqubo zonxibelelwano kunye nezixhobo ezahlukeneyo zombane, njengeenkqubo zonxibelelwano ezihambelanayo, iinkqubo zamanani amaxesha, njl. Iindlela zoyilo eziphambili ziquka indlela yomgca wokulibaziseka kwe-CNC, indlela yememori, i-counter. indlela, njl., apho indlela yenkumbulo iphunyezwa ikakhulu kusetyenziswa iFPGA's RAM okanye FIFO.
Ukusetyenziswa kwe-FPGAs ukufunda nokubhala idatha enxulumene nekhadi le-SD inokusekelwe kwiimfuno ezithile ze-algorithm ye-chip ye-FPGA ephantsi ukwenza inkqubo, utshintsho oluyinyani ngakumbi ukufezekisa imisebenzi yokufunda nokubhala rhoqo ihlaziywa.Le ndlela ifuna kuphela ukusetyenziswa kwe-chip ekhoyo ukufezekisa ulawulo olusebenzayo lwekhadi le-SD, ukunciphisa kakhulu iindleko zenkqubo.

Ushishino lonxibelelwano
Ngokuqhelekileyo, ishishini lonxibelelwano, lithathela ingqalelo yonke imiba efana neendleko kunye nokusebenza, kunokwenzeka ukuba lisebenzise iiFPGA kwiindawo apho inani lezixhobo ze-terminal liphezulu.Izikhululo ezisisiseko zezona zilungele ukusetyenziswa kweFPGAs, apho phantse yonke ibhodi kufuneka isebenzise i-chip FPGA, kwaye iimodeli ziphezulu kwaye zikwazi ukusingatha iiprothokholi eziyinkimbinkimbi zomzimba kwaye zifezekise ulawulo olunengqiqo.Kwangaxeshanye, njengomaleko wekhonkco olungqiqweni lwesikhululo sesiseko, inxalenye yeprotocol yomaleko womzimba kufuneka ihlaziywe rhoqo, nayo ifaneleke ngakumbi kwitekhnoloji yeFPGA.Okwangoku, ii-FPGAs zisetyenziswa ikakhulu kumanqanaba okuqala naphakathi okwakha kushishino lonxibelelwano, kwaye ngokuthe ngcembe zithathelwa indawo zii-ASICs kamva.

Ezinye izicelo
Ii-FPGAs nazo zisetyenziswa ngokubanzi kwizicelo zokhuseleko kunye nezoshishino, umzekelo, i-encoding yevidiyo kunye ne-decoding protocols kwintsimi yokhuseleko inokucutshungulwa ngokusebenzisa ii-FPGAs kwinkqubo yokufumana idatha yangaphambili kunye nokulawula ingqiqo.Ii-FPGA ezincinci zisetyenziswa kwicandelo loshishino ukuhlangabezana nemfuno yokuguquguquka.Ukongeza, ii-FPGA zikwasetyenziswa ngokubanzi emkhosini nakwicandelo le-aerospace ngenxa yokuthembeka kwazo okuphezulu.Kwixesha elizayo, ngokuphuculwa okuqhubekayo kobuchwepheshe, iinkqubo ezifanelekileyo ziya kuphuculwa, kwaye iiFPGA ziya kuba nethemba elibanzi lesicelo kumashishini amaninzi amatsha afana nedatha enkulu.Ngokwakhiwa kweenethiwekhi ze-5G, ii-FPGA ziya kusetyenziswa ngamanani amakhulu kumanqanaba okuqala, kwaye amasimi amatsha afana nobukrelekrele bokufakelwa aya kubona ukusetyenziswa ngakumbi kweFPGAs.
NgoFebruwari 2021, iiFPGAs, ezinokuthengwa kwaye ziyilwe, zazibizwa ngokuba "ziitshiphusi zendalo yonke".Inkampani, enye yeenkampani zasekhaya zokuqala ukuphuhlisa ngokuzimeleyo, ukuvelisa ngobuninzi kunye nokuthengisa iitshiphusi zeFPGA ezinenjongo ngokubanzi, igqibezele utyalo-mali lwe-yuan ezizigidi ezingama-300 kwisizukulwana esitsha se-FPGA yetshiphu yeR&D kunye neprojekthi yoshishino eYizhuang.
