Intangiriro kuri CPLD

Nkuko byaganiriweho mbere, ubwoko butandukanye bwa PLDs (ibikoresho bya logicable programme) birahari, nka FPGA, CPLD, na SPLD.Itandukaniro ryibanze hagati yibi bikoresho biri mu ruziga rugoye n'umubare w'ingirabuzimafatizo ziboneka.SPLD mubisanzwe igizwe namarembo magana, mugihe CPLD igizwe namarembo ibihumbi bike.

Kubijyanye no kugorana, CPLD (igikoresho cyoroshye cya porogaramu ishobora gukoreshwa) iri hagati ya SPLD (igikoresho cyoroshye cya porogaramu ishobora gukoreshwa) na FPGA bityo, ikazungura ibintu muri ibyo bikoresho byombi.CPLDs iragoye kuruta SPLDs ariko ntago igoye kuruta FPGAs.

SPLDs ikoreshwa cyane harimo PAL (programable array logic), PLA (logicable array array), na GAL (generic array logic).PLA igizwe nindege imwe Nindege imwe cyangwa indege.Porogaramu isobanura ibyuma bisobanura guhuza izi ndege.

PAL isa cyane na PLA ariko, hariho indege imwe gusa ishobora gutegurwa aho kuba ibiri (KANDI indege).Mugukosora indege imwe, ibyuma bigoye bigabanuka.Nyamara, iyi nyungu igerwaho ku giciro cyo guhinduka.

CPLD Ubwubatsi

CPLD irashobora gufatwa nkubwihindurize bwa PAL kandi igizwe nuburyo bwinshi bwa PAL buzwi nka macrocells.Muri paki ya CPLD, pin zose zinjiza ziraboneka kuri buri macrocell, mugihe buri macrocell ifite ibisohoka byabigenewe.

Duhereye ku gishushanyo mbonera, dushobora kubona ko CPLD igizwe na macrocells nyinshi cyangwa imikorere yimikorere.Makrocells ihujwe binyuze muri programme ihuza imiyoboro, nayo yitwa GIM (matrix ihuza isi yose).Mugushushanya GIM, imirongo itandukanye ya logique irashobora kugerwaho.CPLDs ikorana nisi yo hanze ikoresha digital I / Os.

Itandukaniro hagati ya CPLD na FPGA

Mu myaka yashize, FPGAs yamenyekanye cyane mugushushanya sisitemu ya sisitemu ishobora gukoreshwa.Hariho byinshi bisa kimwe nibitandukaniro hagati ya CPLD na FPGA.Kubijyanye nibisa, byombi nibikoresho byogushobora gukoreshwa bigizwe na logic gate ya array.Ibikoresho byombi byateguwe hakoreshejwe HDL nka Verilog HDL cyangwa VHDL.

Itandukaniro ryambere hagati ya CPLD na FPGA riri mumibare y amarembo.CPLD ikubiyemo amarembo ibihumbi bike, mugihe umubare wamarembo muri FPGA ushobora kugera kuri miriyoni.Kubwibyo, imirongo igoye hamwe na sisitemu birashobora kugerwaho ukoresheje FPGAs.Ingaruka zibi bigoye nigiciro cyinshi.Kubwibyo, CPLDs irakwiriye cyane kubisabwa bitoroshye.

Irindi tandukaniro ryingenzi hagati yibi bikoresho byombi nuko CPLDs igaragaramo yubatswe muri EEPROM idahindagurika (amashanyarazi ashobora guhanagurwa na programme random-access memory), mugihe FPGAs yibuka ububiko buhindagurika.Kubera iyo mpamvu, CPLD irashobora kugumana ibiyirimo nubwo byashizwemo ingufu, mugihe FPGA idashobora kugumana ibiyirimo.Byongeye kandi, bitewe nububiko bwubatswe budahindagurika, CPLD irashobora gutangira gukora ako kanya nyuma yimbaraga.Kurundi ruhande FPGAs, bisaba bito-bitemba biva mububiko bwo hanze budahinduka kugirango utangire.

Kubijyanye nimikorere, FPGAs ifite gutinda gutunganyiriza ibimenyetso bitinze kubera ubwubatsi bukomeye cyane buhujwe hamwe na progaramu ya progaramu yihariye.Muri CPLDs, gutinda kwa pin-pin ni bito cyane kubera ubwubatsi bworoshye.Gutinda gutunganya ibimenyetso ni ikintu cyingenzi mugushushanya umutekano-ushimishije kandi ushizemo igihe-nyacyo.

Bitewe numurongo mwinshi wo gukora hamwe nibikorwa bigoye bya logique, FPGAs zimwe zishobora gukoresha imbaraga zirenze CPLDs.Rero, imicungire yumuriro nigitekerezo cyingenzi muri sisitemu ishingiye kuri FPGA.Kubera iyo mpamvu, sisitemu ishingiye kuri FPGA akenshi ikoresha ibyuma bifata ubushyuhe hamwe nabafana bakonjesha kandi ikenera amashanyarazi manini kandi akomeye kandi akomeye.

Duhereye kumutekano wamakuru, CPLDs ifite umutekano nkuko kwibuka byubatswe muri chip ubwayo.Ibinyuranye, FPGAs nyinshi zisaba ububiko bwo hanze budahindagurika, bushobora guhungabanya umutekano.Nubwo amakuru yo kubika amakuru algorithms ari muri FPGAs, CPLDs isanzwe ifite umutekano ugereranije na FPGAs.
