The is CPLD ndi lalifupi la Complex Programmable Logic Device.Ndi gawo lamalingaliro lomwe ndi lovuta kwambiri kuposa PLD.CPLD ndi mtundu wamagawo ophatikizika a digito omwe ogwiritsa ntchito amapanga malingaliro malinga ndi zosowa zawo.Njira yoyambira yopangira ndikugwiritsa ntchito nsanja yophatikizira yachitukuko, pogwiritsa ntchito chilankhulo, chilankhulo chofotokozera za Hardware ndi njira zina, kupanga fayilo yofananira, kudzera pa chingwe chotsitsa ("mu "programming)" kutumiza kachidindo ku chip chandamale. , kuti akwaniritse mapangidwe a digito.

M'zaka za m'ma 1970, PLD, chida choyambirira kwambiri chokonzekera, chinabadwa.mawonekedwe ake linanena bungwe ndi programmable logic macro unit, chifukwa hardware kapangidwe kapangidwe akhoza kumalizidwa ndi mapulogalamu (ofanana ndi nyumba pambuyo pomanga kamangidwe kamanja kamangidwe kagawo mkati), kotero mapangidwe ake ali ndi kusinthasintha amphamvu kuposa koyera hardware digito dera, koma mawonekedwe ake osavuta amawapangitsanso kuti athe kukwaniritsa dera laling'ono.Pofuna kukonza zolakwika zomwe PLD imangopanga kagawo kakang'ono, pakati pa zaka za m'ma 1980, chipangizo chosavuta chokonzekera -CPLD chinayambitsidwa.Pakadali pano, kugwiritsa ntchito kwakhala kozama pamaneti, zida, zamagetsi zamagalimoto, zida zamakina a CNC, zida zamlengalenga za TT&C ndi zina.

Ili ndi mawonekedwe a mapulogalamu osinthika, kuphatikiza kwakukulu, kapangidwe kakang'ono ndi kakulidwe kachitukuko, mawonekedwe osiyanasiyana ogwiritsira ntchito, zida zachitukuko zotsogola, mapangidwe otsika ndi mtengo wopangira, zotsika mtengo zopangira zida za opanga, osayesa zinthu zokhazikika, chinsinsi cholimba, mtengo wotchuka. , ndi zina zotero.Ikhoza kuzindikira mapangidwe akuluakulu ozungulira.Choncho, chimagwiritsidwa ntchito prototyping ndi kupanga zinthu (nthawi zambiri zosakwana 10,000 zidutswa).Zipangizo za CPLD zitha kugwiritsidwa ntchito pafupifupi pamagawo onse ang'onoang'ono ndi apakatikati a digito ophatikizika.Zipangizo za CPLD zakhala gawo lofunikira kwambiri pazinthu zamagetsi, ndipo mapangidwe ake ndikugwiritsa ntchito kwake kwakhala luso lofunikira kwa mainjiniya apakompyuta.

Pambuyo pakukula kwazaka zambiri, makampani ambiri apanga zida zomangira za CPLD.Zomwe zimagulitsidwa ndi Altera, Lattice ndi Xilinx, makampani atatu ovomerezeka padziko lonse lapansi.
