Iyo CPLD ipfupi yeComplex Programmable Logic Device.Icho chinhu chine musoro chakaoma kupfuura PLD.CPLD imhando yedhijitari yakabatanidzwa sedunhu iyo vashandisi vanovaka logic basa zvinoenderana nezvavanoda.Iyo yakakosha dhizaini nzira ndeye kushandisa yakasanganiswa yekuvandudza software chikuva, uchishandisa schematic, hardware tsananguro mutauro uye dzimwe nzira, kugadzira inoenderana chinhu faira, kuburikidza nedhawunirodha tambo (" muhurongwa "programming) kutumira kodhi kune chinangwa chip. , kuti uwane dhizaini yedhijitari system.

Mumakore ekuma1970, PLD, yekutanga yakarongwa logic mudziyo, yakazvarwa.Chimiro chayo chinobuda chinorongeka logic macro unit, nekuti dhizaini yayo yedhizaini inogona kupedzwa nesoftware (yakaenzana neimba mushure mekuvakwa kwemanyorero dhizaini yechikamu chemukati chimiro), saka dhizaini yayo ine kuchinjika kwakasimba kupfuura pure Hardware digital circuit, asi. chimiro chayo chakareruka zvakare chinoita kuti vagone kuwana diki diki redunhu.Kuti igadzirise chirema icho PLD inogona chete kugadzira dunhu diki, pakati pe1980s, yakaoma programmable logic mudziyo -CPLD yakaunzwa.Parizvino, chikumbiro chave chakadzika munetiweki, chiridzwa, mota dzemagetsi, CNC muchina maturusi, aerospace TT&C michina uye zvimwe zvinhu.

Iyo ine hunhu hwekuchinjika hurongwa, kubatanidzwa kwepamusoro, dhizaini pfupi uye kutenderera kutenderera, yakafara dhizaini, maturusi ekusimudzira epamberi, yakaderera dhizaini uye mutengo wekugadzira, zvakaderera zvinodiwa kune vanogadzira 'hardware ruzivo, hapana kuyedzwa kwezvakajairwa zvigadzirwa, kuvanzika kwakasimba, mutengo wakakurumbira. , zvichingoenda zvakadaro.Inogona kuona yakakura-chiyero chedunhu dhizaini.Nokudaro, inoshandiswa zvakanyanya mu prototyping uye kugadzirwa kwezvigadzirwa (kazhinji zvisingasviki zvidimbu zve10,000).Zvishandiso zveCPLD zvinogona kushandiswa mune zvingangoita zvese zvinoshandiswa zvemadiki uye epakati-saizi epasirese dhijitari akabatanidzwa maseketi.Zvishandiso zveCPLD zvave chikamu chakakosha chezvigadzirwa zvemagetsi, uye dhizaini nekushandisa kwave hunyanzvi hwakakosha kune mainjiniya emagetsi.

Mushure memakumi emakore ebudiriro, makambani mazhinji akagadzira CPLD programmable logic zvishandiso.Izvo zvakajairwa zvigadzirwa ndeizvo zveAltera, Lattice uye Xilinx, aya matatu ane chiremera makambani munyika.
