Ulwahlulo lokusiNgqongileyo nokuThunyela ngaphandle

I-CPLD imfutshane kwi-Complex Programmable Logic Device.Licandelo lengqiqo elintsonkothe ​​ngakumbi kune-PLD.I-CPLD luhlobo lwesekethe edityanisiweyo yedijithali apho abasebenzisi bakha umsebenzi onengqondo ngokweemfuno zabo.Indlela yoyilo esisiseko kukusebenzisa iqonga elidityanisiweyo lophuhliso lwesoftware, kusetyenziswa ischematic, ulwimi lwengcaciso yehardware kunye nezinye iindlela, ukuvelisa ifayile yento ehambelanayo, ngentambo yokukhuphela (” kwinkqubo “yenkqubo) ukuthumela ikhowudi kwitshiphu ekujoliswe kuyo. , ukufezekisa uyilo lwenkqubo yedijithali.

Ngeminyaka yee-1970, i-PLD, esona sixhobo sokuqala sinocwangciso, sazalwa.Ulwakhiwo lwalo lwemveliso lucwangcisiweyo lweyunithi ye-logic macro, kuba uyilo lwesakhiwo sayo se-hardware inokugqityezelwa ngesoftware (elingana nendlu emva kolwakhiwo loyilo lwezandla lwesakhiwo esingaphakathi), ngoko uyilo lwayo lunoguquguquka olomeleleyo kunesekethe yedijithali esulungekileyo, kodwa ulwakhiwo lwalo olulula kakhulu lubenza bakwazi ukufikelela kuphela kwisekethe yesikali esincinci.Ukuze kulungiswe isiphene ukuba i-PLD inokuyila kuphela isiphaluka esincinci, phakathi kwe-1980, isixhobo esiyinkimbinkimbi esicwangcisiweyo esicwangcisiweyo -CPLD saziswa.Okwangoku, isicelo sele sinzulu kwinethiwekhi, izixhobo, i-automotive electronics, izixhobo zomatshini we-CNC, izixhobo ze-aerospace TT & C kunye nezinye iinkalo.

Ineempawu zenkqubo eguquguqukayo, ukuhlanganiswa okuphezulu, uyilo olufutshane kunye nomjikelezo wophuhliso, uluhlu olubanzi lwezicelo, izixhobo zophuhliso oluphezulu, uyilo oluphantsi kunye neendleko zokuvelisa, iimfuno eziphantsi zamava e-hardware abaqulunqi, akukho vavanyo lweemveliso eziqhelekileyo, imfihlo eyomeleleyo, ixabiso elidumileyo. , kwaye nangokunjalo.Inokuqonda uyilo lwesekethe enkulu.Ngoko ke, isetyenziswa ngokubanzi kwiprototyping kunye nokuveliswa kweemveliso (ngokuqhelekileyo ngaphantsi kwamaqhekeza angama-10,000).Izixhobo ze-CPLD zinokusetyenziswa phantse kuzo zonke izicelo zeesekethe ezihlanganisiweyo zedijithali ezincinci kunye neziphakathi.Izixhobo ze-CPLD ziye zaba yinxalenye ebalulekileyo yeemveliso zombane, kwaye uyilo nokusetyenziswa kwayo kuye kwaba sisakhono esibalulekileyo kwiinjineli zombane.

Emva kwamashumi eminyaka yophuhliso, iinkampani ezininzi ziye zaphuhlisa izixhobo ze-CPLD ezicwangcisiweyo.Iimveliso eziqhelekileyo zezo ze-Altera, Lattice kunye ne-Xilinx, ezi nkampani zintathu zinegunya emhlabeni.
