 Igikoresho kitoroshye gishobora gukoreshwa (CPLD) nigikoresho cyumvikana gifite porogaramu zishobora KANDI / CYANGWA na macrocells.Macrocells ninzitizi nyamukuru yubaka ya CPLD, ikubiyemo ibikorwa bya logique bigoye hamwe na logique yo gushyira mubikorwa imvugo isanzwe itandukanye.KANDI / CYANGWA imirongo irashobora gusubirwamo rwose kandi ishinzwe gukora imirimo itandukanye.Macrocells irashobora kandi gusobanurwa nkibice bikora bishinzwe gukora logique ikurikirana cyangwa ikomatanya.

 Igikoresho kitoroshye gishobora gukoreshwa nigicuruzwa gishya ugereranije nibikoresho byabanjirije logique nka programme ya logic array (PLAs) na Programmable Array Logic (PAL).Ibikoresho bya logique byambere ntabwo byari programable, logique rero yubatswe muguhuza chip nyinshi za logic hamwe.CPLD ifite ingorane hagati ya PALs na field-programable gate gate arrayes (FPGAs).Ifite kandi imiterere yububiko bwa PALs na FPGAs.Itandukaniro nyamukuru ryubwubatsi hagati ya CPLD na FPGA nuko FPGAs ishingiye kumeza yo kureba, mugihe CPLDs ishingiye ku nyanja-y-amarembo.

Ibintu bisanzwe biranga CPLDs na FPGAs nuko byombi bifite umubare munini wamarembo hamwe ningingo zoroshye za logique.Mugihe ibintu bisanzwe hagati ya CPLDs na PALs harimo ububiko bwibikoresho budahindagurika.CPLDs ni abayobozi mwisoko ryibikoresho byifashishwa byifashishwa, bifite inyungu nyinshi nka progaramu ya progaramu yambere, igiciro gito, kuba idahindagurika kandi byoroshye gukoresha.

 A.igikoresho cyoroshye gishobora gukoreshwa(CPLD) ni aigikoresho gishobora gukoreshwahamwe ningorabahizi hagati yiyoPALnaFPGAs, hamwe nubwubatsi buranga byombi.Inzira nyamukuru yo kubaka CPLD ni amacrocell, ikubiyemo gushyira mu bikorwa logiqueimiterere isanzweimvugo nibikorwa byihariye bya logique.

Ibiranga [Hindura]

Bimwe mubiranga CPLD birahuriweho naPAL:

• Ububiko bwibikoresho budahindagurika.Bitandukanye na FPGAs nyinshi, iboneza ryo hanzeROMntibisabwa, kandi CPLD irashobora gukora ako kanya kuri sisitemu yo gutangira.
• Kubikoresho byinshi byumurage CPLD, inzira ibuza logique nyinshi kugirango igire ibyinjira nibisohoka bihujwe na pin yo hanze, bigabanya amahirwe yo kubika leta imbere hamwe na logique yimbitse.Mubisanzwe ntabwo arimpamvu ya CPLD nini nimiryango mishya ya CPLD.

Ibindi biranga bihuriweho naFPGAs:

• Umubare munini w'amarembo arahari.CPLDs mubisanzwe ifite ibihumbi n'ibihumbiamarembo yumvikana, kwemerera gushyira mubikorwa ibikoresho bigoye gutunganya amakuru.PAL mubisanzwe ifite amarembo magana ahwanye na menshi, mugihe FPGAs isanzwe kuva mubihumbi icumi kugeza kuri miliyoni.
• Ingingo zimwe na zimwe za logique zoroshye kurutaigiteranyo-cy'ibicuruzwaimvugo, harimo inzira zoroshye zo gutanga ibitekerezo hagati ya macro selile, hamwe na logique yihariye yo gushyira mubikorwa ibikorwa bisanzwe bikoreshwa, nkainteger imibare.

Itandukaniro rigaragara cyane hagati ya CPLD nini na FPGA ntoya ni ukubaho kuri chip yibuka idafite imbaraga muri CPLD, ituma CPLDs ikoreshwa kuri “boot boot”Imikorere, mbere yo gutanga igenzura kubindi bikoresho bidafite ububiko bwa porogaramu zihoraho.Urugero rwiza niho CPLD ikoreshwa mugutwara amakuru yimiterere ya FPGA kuva mububiko budahindagurika.^[1]

Itandukaniro [Hindura]

CPLDs yari intambwe yubwihindurize kuva kubikoresho bito byababanjirije,PLAs(ubanza koherezwa naUmukono), naPAL.Izi nazo zabanjirijwe nalogique isanzweibicuruzwa, bidatanga porogaramu kandi byakoreshwaga mu kubaka imikorere ya logique ukoresheje insinga zisanzwe zisanzwe (cyangwa amagana yazo) hamwe (mubisanzwe hamwe no gukoresha insinga ku kibaho cyacapwe cyangwa ku kibaho, ariko rimwe na rimwe, cyane cyane kuri prototyping, ukoreshejegupfunyika insingawiring).

Itandukaniro nyamukuru hagati yububiko bwa FPGA na CPLD ni uko CPLDs ishingiye imbereImbonerahamwe(LUTs) mugihe FPGAs ikoreshaguhagarika ibitekerezo.
