Izimfanelo Zomkhiqizo

Izigaba Zemvelo Nokuthekelisa

I-is CPLD imfushane ye-Complex Programmable Logic Device.Kuyingxenye enengqondo eyinkimbinkimbi kune-PLD.I-CPLD iwuhlobo lwesekethe edidiyelwe yedijithali abasebenzisi abakha umsebenzi onengqondo ngokwezidingo zabo.Indlela yokuklama eyisisekelo iwukusebenzisa inkundla yesofthiwe yokuthuthukisa edidiyelwe, kusetshenziswa isikimu, ulimi lokuchaza ihadiwe nezinye izindlela, ukukhiqiza ifayela lezinto elihambisanayo, ngekhebula yokulanda (” ohlelweni “lohlelo) ukuthumela ikhodi ku-chip eqondiwe. , ukuze kuzuzwe ukuklanywa kohlelo lwedijithali.

Ngawo-1970s, kwazalwa i-PLD, idivayisi yokucabanga ehlelekayo yokuqala.Isakhiwo sayo esiphumayo siyiyunithi ehlelekayo ye-logic macro, ngoba ukwakheka kwayo kwesakhiwo sehadiwe kungaqedwa ngesoftware (elingana nendlu ngemuva kokwakhiwa komklamo owenziwe ngesandla wesakhiwo sangaphakathi esiyingxenye), ngakho-ke ukwakheka kwayo kunokuguquguquka okunamandla kunesekhethi yedijithali yehadiwe emsulwa, kodwa isakhiwo sayo esilula kakhulu futhi sibenza bakwazi ukufeza isifunda esincane esikalini.Ukuze kulungiswe isici sokuthi i-PLD ingakwazi ukuklama isifunda esincane kuphela, maphakathi nawo-1980, kwasungulwa idivayisi eyinkimbinkimbi ehlelekayo -CPLD.Njengamanje, uhlelo lokusebenza lujulile kunethiwekhi, i-instrumentation, i-electronics yezimoto, amathuluzi omshini we-CNC, imishini ye-aerospace TT & C nezinye izici.

Inezici zohlelo oluguquguqukayo, ukuhlanganiswa okuphezulu, ukuklama okufushane nomjikelezo wokuthuthukiswa, ububanzi bohlelo lokusebenza, amathuluzi okuthuthukiswa okuthuthukisiwe, umklamo ophansi kanye nezindleko zokukhiqiza, izidingo eziphansi zokuhlangenwe nakho kwe-hardware yabaklami, akukho ukuhlolwa kwemikhiqizo ejwayelekile, ukugcinwa kuyimfihlo okuqinile, intengo ethandwayo. , njalo njalo.Ingakwazi ukubona ukwakheka kwesekethe enkulu.Ngakho-ke, isetshenziswa kabanzi ekukhiqizeni nasekukhiqizeni imikhiqizo (ngokuvamile izingcezu ezingaphansi kuka-10,000).Amadivaysi e-CPLD angasetshenziswa cishe kuzo zonke izinhlelo zokusebenza zamasekhethi ahlanganisiwe edijithali amancane naphakathi nendawo.Imishini ye-CPLD isiyingxenye ebalulekile yemikhiqizo ye-elekthronikhi, futhi ukwakheka nokusebenza kwayo sekuphenduke ikhono elibalulekile konjiniyela be-elekthronikhi.

Ngemuva kwamashumi eminyaka entuthuko, izinkampani eziningi zenze amadivaysi anengqondo ahlelekayo e-CPLD.Imikhiqizo ejwayelekile yileyo yakwa-Altera, Lattice kanye ne-Xilinx, lezi zinkampani ezintathu ezigunyaziwe emhlabeni.
