Ziza ntoni iiFPgas?

I-SoC eyenziwe ngokwezifiso kakhulu.Umzekelo - ujongano olusemgangathweni oluqhagamshelwe kwizinto eziqhelekileyocpuskunye neebhloko zengqiqo eziphuculweyo.Ngenxa yoko, abadibanisi beenkqubo bazisa izisombululo ezidibanisa kwimida yorhwebo eqhelekileyo (izinto ezintsha eziphazamisayo).Ke into ethi qatha engqondweni apha kukuqalwa kwehardware kwimimandla yokhuseleko, inethiwekhi, amaziko edatha, njl.

Ukwengeza,FPGasinokusetyenziswa nge-powerpc okanye i-ARM-based cpus.Ke, kunokwenzeka ukuphuhlisa ngokukhawuleza i-SoC eya kuba ne-interface enokwenzeka ngokwezifiso malunga ne-CPU apho ikhowudi ekhoyo sele iphuhlisiwe.Ngokomzekelo, amakhadi okukhawulezisa i-hardware yokurhweba okuphezulu-frequency.

I-FPgas ephezulu isetyenziselwa ukufumana "ikhululekile" i-interfaces yokusebenza ephezulu njenge-PCIe Gen 3, i-10 / 40Gbps Ethernet, i-SATA Gen 3, i-DDR3 gobs kunye ne-gobs, imemori ye-QDR4.Ngokuqhelekileyo, ukufumana le ip kwi-ASIC kuyabiza.Kodwa iFPgas inokukuqalisa ngokukhawuleza, kuba ezi cores zinokusetyenziswa njengeetshiphusi esele zingqinwe, ngoko ke kuthatha iqhezu lexesha lophuhliso ukuzidibanisa kwinkqubo.

IiFpgas zineziphindaphindi ezimbalwa kunye nememori yangaphakathi.Ngoko ke, zifaneleke kakuhle kwiinkqubo zokucwangcisa iimpawu.Ke ngoko, uya kuzifumana kwihardware eyenza imeko yophawu kunye ne-multiplexing/demultiplexing.Umzekelo, izixhobo zenethiwekhi ezingenazingcingo, ezifana nezitishi ezisisiseko.

Eyona nto incinci inengqondo kwiFPGA ibizwa ngokuba yibhloko enengqondo.Oku noko kukubangela i-ALU+.Ngenxa yoko, iiFPgas zisetyenziswa ngokubanzi kwiingxaki zekhompuyutha ezinokuzuza kuyilo lwe-SIMD yohlobo.Imizekelo ibandakanya ukucoca imifanekiso efunyenwe kwi-sensors yemifanekiso, inqaku okanye inkqubo yendawo yeepikseli zomfanekiso, njengokubala iivectors ezahlukeneyo kwi-H.264 compression, njl.

Ekugqibeleni, ukulinganisa kwe-ASIC okanye i-hardware / isofthiwe kuvavanyo lwendandatho, njl. I-FPGA yoyilo lwengqiqo yabelana ngeenkqubo ezifanayo kunye nezixhobo njenge-ASIC yoyilo.I-Fpgas ke ngoko isetyenziselwa ukuqinisekisa ezinye iimeko zovavanyo ngexesha lophuhliso lwe-ASIC, apho ukusebenzisana phakathi kwe-hardware kunye nesoftware kunokuba nzima kakhulu okanye kuthathe ixesha ukwenza imodeli.

Ngoku ujonge ezi zibonelelo zingentla zeFPGA, ingasetyenziswa ku:

1.nasiphi na isisombululo esifuna ukuphuhliswa kwee-SOC zesiko kusetyenziswa iimodyuli eziphuculweyo zentsimi.

2.inkqubo yokucwangcisa uphawu

3. Ukulungiswa komfanekiso kunye nokuphucula

I-4.CPU i-accelerators yokufunda koomatshini, ukuqaphela umfanekiso, ukunyanzeliswa kunye neenkqubo zokukhusela, iinkqubo zokurhweba eziphezulu, njl.

5. I-ASICukulinganisa kunye nokuqinisekisa

Ukuya inyathelo eliya phambili, ungahlula imarike ukuba iinkqubo ezisekwe kwiFPGA zinokusebenza kakuhle

1, idinga ukusebenza okuphezulu kodwa ayikwazi ukumelana ne-NRE ephezulu.Ngokomzekelo, izixhobo zenzululwazi

2. Akunakuboniswa ukuba kufuneka amaxesha amade okukhokela ukufumana umsebenzi ofunekayo.Ngokomzekelo, ukuqaliswa kwiindawo ezinjengokhuseleko, ifu / i-data center ye-virtualization server, njl. zama ukubonisa ingcamango kwaye uphindaphinde ngokukhawuleza.

3. Uyilo lwe-SIMD olunemfuno ezinkulu zokucwangcisa umqondiso.Umzekelo, izixhobo zonxibelelwano ezingenazingcingo.
