CPLD (Complex Programmable Logic Device) yog dab tsi?

Cov ntaub ntawv thev naus laus zis, internet, thiab cov khoom siv hluav taws xob ua haujlwm ua lub hauv paus ntawm lub hnub nyoog digital niaj hnub.Yuav luag tag nrho cov thev naus laus zis niaj hnub no tshuav lawv qhov muaj nyob rau hauv electronics, los ntawm internet thiab cellular kev sib txuas lus mus rau computers thiab servers.Electronics yog qhov chaw loj heev nrogntau sub-sab.Kab lus no yuav qhia koj txog qhov tseem ceeb ntawm cov khoom siv hluav taws xob digital hu ua CPLD (Complex Programmable Logic Device).

Evolution ntawm Digital Electronics

Electronicsyog ib thaj chaw nyuaj nrog ntau txhiab cov khoom siv hluav taws xob thiab cov khoom siv hauv hav zoov.Txawm li cas los xij, hais dav dav, cov khoom siv hluav taws xob muaj nyob hauv ob pawg loj:analog thiab digital.

Nyob rau hauv thaum ntxov hnub ntawm electronics technology, circuits yog analogous, xws li suab, lub teeb, voltage, thiab tam sim no.Txawm li cas los xij, cov kws tshaj lij hluav taws xob tau pom sai sai tias cov analog circuits yog qhov nyuaj heev rau kev tsim thiab kim.Qhov kev thov rau kev ua haujlwm nrawm thiab lub sijhawm tig rov qab sai tau ua rau kev txhim kho cov khoom siv hluav taws xob digital.Niaj hnub no yuav luag txhua lub khoos phis tawj hauv lub neej muaj xws li digital ICs thiab processors.Hauv ntiaj teb cov khoom siv hluav taws xob, cov tshuab digital tau tam sim no hloov pauv cov khoom siv hluav taws xob analog tag nrho vim lawv cov nqi qis, suab nrov, zoo dua.teeb liab kev ncaj ncees, superior kev ua tau zoo, thiab qis complexity.

Tsis zoo li tus lej ntawm cov ntaub ntawv tsis kawg hauv cov teeb liab analog, lub teeb liab digital tsuas muaj ob theem logic (1s thiab 0s).

Hom Cov Khoom Siv Hluav Taws Xob Digital

Cov khoom siv hluav taws xob digital thaum ntxov tau yooj yim dua thiab tsuas yog muaj qee qhov ntawm cov rooj vag logic nkaus xwb.Txawm li cas los xij, dhau sijhawm, qhov nyuaj ntawm cov circuits digital tau nce ntxiv, yog li programmability tau dhau los ua ib qho tseem ceeb ntawm cov cuab yeej tswj digital niaj hnub no.Ob chav kawm sib txawv ntawm cov khoom siv digital tau tshwm sim los muab cov programmability.Thawj chav kawm muaj cov kho vajtse tsim kho nrog cov software reprogrammable.Piv txwv ntawm cov khoom siv xws li microcontrollers thiab microprocessors.Cov chav kawm thib ob ntawm cov khoom siv digital featured reconfigurable hardware kom ua tau yooj yim logic Circuit Court tsim.Piv txwv ntawm cov khoom siv xws li FPGAs, SPLDs, thiab CPLDs.

Lub microcontroller nti nta ib lub voj voog digital logic uas tsis tuaj yeem hloov kho.Txawm li cas los xij, programmability tau ua tiav los ntawm kev hloov software / firmware uas khiav ntawm microcontroller nti.Ntawm qhov tsis sib xws, PLD (programmable logic device) muaj ntau lub hlwb logic uas nws cov kev sib txuas tuaj yeem teeb tsa siv HDL (cov lus piav qhia kho vajtse).Yog li ntawd, ntau lub logic circuits tuaj yeem paub siv PLD.Vim li no, qhov kev ua tau zoo thiab ceev ntawm PLDs feem ntau zoo dua li ntawm microcontrollers thiab microprocessors.PLDs tseem muab cov qauv tsim hluav taws xob nrog rau qib siab dua ntawm kev ywj pheej thiab yoog raws.

Integrated circuits txhais tau tias rau digital tswj thiab teeb liab ua feem ntau muaj xws li processor, logic circuit, thiab nco.Txhua qhov ntawm cov qauv no tuaj yeem pom tau siv cov thev naus laus zis sib txawv.

Taw qhia rau CPLD

Raws li tau tham dhau los, ntau hom PLDs (programmable logic devices) muaj nyob, xws li FPGA, CPLD, thiab SPLD.Thawj qhov sib txawv ntawm cov khoom siv no yog nyob rau hauv Circuit Court complexity thiab tus naj npawb ntawm cov logic hlwb muaj.Ib qho SPLD feem ntau muaj ob peb puas lub rooj vag, qhov CPLD muaj ob peb txhiab lub rooj vag logic.

Nyob rau hauv cov nqe lus ntawm complexity, CPLD (complex programmable logic ntaus ntawv) nyob nruab nrab ntawm SPLD (yooj yim programmable logic ntaus ntawv) thiab FPGA thiab yog li, inherits nta ntawm ob qho tib si pab kiag li lawm.CPLDs yog qhov nyuaj dua li SPLDs tab sis tsawg dua li FPGAs.

Feem ntau siv SPLDs suav nrog PAL (programmable array logic), PLA (programmable logic array), thiab GAL (generic array logic).PLA muaj ib lub dav hlau THIAB ib lub dav hlau LOSSIS.Lub khoos phis tawj piav qhia kho vajtse txhais cov kev sib txuas ntawm cov dav hlau no.

PAL zoo ib yam li PLA txawm li cas los xij, tsuas muaj ib lub dav hlau programmable xwb tsis yog ob (TSIS dav hlau).Los ntawm kev kho ib lub dav hlau, kho vajtse complexity txo.Txawm li cas los xij, qhov txiaj ntsig no tau ua tiav ntawm tus nqi hloov pauv.

CPLD Architecture

CPLD tuaj yeem suav tias yog kev hloov pauv ntawm PAL thiab muaj ntau lub qauv PAL hu ua macrocells.Nyob rau hauv pob CPLD, tag nrho cov input pins muaj nyob rau txhua lub macrocell, whereas txhua macrocell muaj ib tug siab tso zis tus pin.

Los ntawm daim duab thaiv, peb tuaj yeem pom tias CPLD muaj ntau lub macrocells lossis cov haujlwm thaiv.Cov macrocells txuas nrog los ntawm qhov programmable interconnect, uas tseem hu ua GIM (global interconnection matrix).Los ntawm kev teeb tsa GIM, sib txawv logic circuits tuaj yeem pom tau.CPLDs cuam tshuam nrog lub ntiaj teb sab nrauv siv cov I/Os.

Qhov sib txawv ntawm CPLD thiab FPGA

Nyob rau hauv xyoo tas los no, FPGAs tau dhau los ua neeg nyiam heev hauv kev tsim cov programmable digital systems.Muaj ntau qhov sib xws nrog rau qhov sib txawv ntawm CPLD thiab FPGA.Raws li qhov zoo sib xws, ob qho tib si yog programmable logic li uas muaj logic gate arrays.Ob qho khoom siv yog programmed siv HDLs xws li Verilog HDL lossis VHDL.

Thawj qhov sib txawv ntawm CPLD thiab FPGA yog nyob ntawm cov rooj vag.Ib lub CPLD muaj ob peb txhiab lub rooj vag logic, thaum tus naj npawb ntawm cov rooj vag hauv FPGA tuaj yeem ncav cuag ntau lab.Yog li ntawd, complex circuits thiab systems yuav tsum paub siv FPGAs.Lub downside ntawm no complexity yog tus nqi siab dua.Yog li, CPLDs yog qhov tsim nyog rau kev siv tsawg dua.

Lwm qhov sib txawv tseem ceeb ntawm ob lub cuab yeej no yog tias CPLDs muaj qhov ua kom tsis muaj teeb meem EEPROM (tsim hluav taws xob tshem tawm programmable random-access nco), thaum FPGAs muaj lub cim xeeb tsis zoo.Vim li no, CPLD tuaj yeem khaws nws cov ntsiab lus txawm tias thaum lub hwj chim tawm, thaum FPGA tsis tuaj yeem khaws nws cov ntsiab lus.Ntxiv mus, vim yog built-in tsis-volatile nco, CPLD tuaj yeem pib ua haujlwm tam sim tom qab fais fab tuag.Feem ntau FPGAs, ntawm qhov tod tes, xav tau me ntsis-kwj los ntawm lub cim xeeb sab nraud uas tsis muaj qhov tsis zoo rau kev pib.

Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, FPGAs muaj ib tug unpredictable teeb liab ua ncua ncua sij hawm vim muaj complex architecture ua ke nrog tus neeg siv cov kev cai programming.Hauv CPLDs, tus pin-to-pin ncua qeeb me me vim yog cov qauv yooj yim dua.Lub teeb liab ua haujlwm qeeb yog qhov tseem ceeb hauv kev tsim qauv ntawm kev nyab xeeb-tseem ceeb thiab embedded real-time applications.

Vim muaj kev khiav hauj lwm ntau zaus thiab kev ua haujlwm nyuaj dua, qee qhov FPGAs yuav siv zog ntau dua li CPLDs.Yog li, kev tswj xyuas thermal yog qhov tseem ceeb hauv FPGA-based systems.Vim li no, FPGA raws li cov tshuab feem ntau siv cov dab dej kub thiab cov kiv cua txias thiab xav tau cov khoom siv hluav taws xob ntau dua thiab cov khoom siv sib faib.

Los ntawm cov ntaub ntawv kev ruaj ntseg ntawm qhov pom, CPLDs muaj kev nyab xeeb dua li lub cim xeeb tau tsim rau hauv nti nws tus kheej.Ntawm qhov tsis sib xws, feem ntau FPGAs yuav tsum muaj lub cim xeeb sab nraud uas tsis muaj kev cuam tshuam, uas tuaj yeem ua rau cov ntaub ntawv kev nyab xeeb hem.Txawm hais tias cov ntaub ntawv encryption algorithms yog nyob rau hauv FPGAs, CPLDs muaj kev nyab xeeb dua nyob rau hauv kev sib piv rau FPGAs.

Kev siv ntawm CPLD

CPLDs pom lawv daim ntawv thov nyob rau hauv ntau qhov tsawg-rau-nruab nrab complexity digital tswj thiab teeb liab ua circuits.Qee cov ntawv thov tseem ceeb suav nrog:

1. CPLDs tuaj yeem siv los ua bootloaders rau FPGAs thiab lwm yam programmable systems.
2. CPLDs feem ntau yog siv los ua qhov chaw decoders thiab lub xeev cov tshuab hauv cov tshuab digital.
3. Vim lawv qhov me me thiab siv hluav taws xob tsawg, CPLDs yog qhov zoo tagnrho rau kev siv hauv portable thiabtuavcov khoom siv digital.
4. CPLDs kuj tseem siv rau hauv daim ntawv thov kev nyab xeeb-tseem ceeb.
