Igama eliphelele le-FPGA yi-Field-Programmable Gate Array.I-FPGA ingumkhiqizo wokuthuthuka okuqhubekayo ngesisekelo se-PAL, GAL, CPLD namanye amadivaysi ahlelekayo.Njengomjikelezo owenziwe ngokwezifiso emkhakheni we-ASIC, i-FPGA ayixazululi kuphela ukushoda kwesekhethi eyenziwe ngokwezifiso, kodwa futhi inqoba ukushiyeka kwenombolo elinganiselwe yesekethe yesango ledivayisi ehlelekayo yasekuqaleni.Ngamafuphi, i-FPGA iyi-chip engahlelwa ukuthi iguqule ukwakheka kwayo kwangaphakathi.

Kule minyaka embalwa edlule, indima ye-FPGA ekuthuthukisweni kwezinhlelo zokuxhumana nezokuxhumana iye yanda kakhulu yadlula ukusetshenziswa nje ukuhlanganisa ingqondo phakathi kwezingxenye ezihlukene ebhodini lesekethe elihlanganisiwe.Izixazululo ezisekelwe ku-FPGA zinikeza ukusebenza, ukusebenza, nokuvumelana nezimo kwezixazululo ze-chip ezizinikele kuyilapho kunciphisa izindleko zokuthuthukiswa.Ngezindleko ezinciphayo zamadivayisi e-FPGA kanye nokwanda kokuminyana/ukusebenza, ama-FPGA anamuhla angakwazi ukumboza yonke into kusukela ekugcineni okuphansi kwe-DSLAM namaswishi e-Ethernet kuye kumarutha ayinhloko wokugcina kanye namadivayisi e-WDM.

Ukuvela kwe-FPGA emikhiqizweni yezimoto kanye nobuchwepheshe be-elekthronikhi yezimoto kulethe izinguquko eziguquguqukayo, imboni yezimoto emhlabeni wonke i-FPGA esetshenziswayo, kusukela kuphrosesa yangaphambili ye-FPGA ye-monolithic ethuthukiswe yaba iphrosesa ye-FPGA eminingi, noma i-FPGA yohlu lwamaphrosesa anesivinini esikhulu.Imikhiqizo ye-elekthronikhi yezimoto esekelwe ku-FPGA ingahlangabezana nezidingo zokuthuthukiswa kwezimoto zesikhathi esizayo, futhi enkathini yamamodeli amaningi ahlala ndawonye, ​​inkundla evamile yezingxenyekazi zekhompiyutha eyakhelwe nge-FPGA njengomongo ingafinyelela ukuhambisana ngezindlela ezihlukene zokulayisha isofthiwe.Ngokuthuthuka okuqhubekayo kobuchwepheshe be-elekthronikhi bezimoto esikhathini esizayo, ijubane le-FPGA lizoqhubeka nokuthuthuka.

Ngokuqondene nemakethe yezimboni, isiphenduke imakethe eyisicaba kodwa ekhula kancane embonini ye-semiconductor.Uma kuqhathaniswa nokuthakasela kwemikhiqizo yabathengi, imakethe yezimboni ibonakala inokwethenjelwa kakhulu, ikakhulukazi emakethe enzima njengalena yamanje, enikeza imboni ye-semiconductor imfudumalo.Kumadivayisi akhethekile anamandla njenge-FPGA, ukuthuthukiswa okuzinzile kwemakethe yezimboni kulethe ithuba elikhulu lokuthuthuka.
