MAX® V CPLDs

Altera MAX® V CPLDs inopa kukosha kweiyo indasitiri mumutengo wakaderera, yakaderera simba CPLDs, ichipa yakasimba maficha matsva anosvika makumi mashanu muzana epasi simba rose kana ichienzaniswa nemakwikwi eCPLD.Altera MAX V zvakare inoratidzira yakasarudzika, isiri-inotenderera yekuvaka uye imwe yeindasitiri yakakura density CPLDs.Pamusoro pezvo, iyo MAX V inosanganisa mabasa mazhinji aimbove kunze, senge flash, RAM, oscillators, uye chikamu-akakiyiwa zvishwe, uye muzviitiko zvakawanda, inoburitsa akawanda maI/Os uye logic pane tsoka pamutengo wakafanana nemakwikwi eCPLDs. .Iyo MAX V inoshandisa yakasvibira yekurongedza tekinoroji, ine mapakeji madiki se20 mm2.MAX V CPLDs inotsigirwa neQuartus II® Software v.10.1, iyo inobvumira kuvandudzwa kwezvibereko zvinokonzera kukurumidza kufananidza, kukurumidza kuunza bhodhi, uye kukurumidza kuvhara nguva.

Chii chinonzi CPLD (Complex Programmable Logic Device)?

Tekinoroji yeruzivo, internet, uye machipisi emagetsi anoshanda senheyo yezera remazuvano redhijitari.Anenge ese emazuvano matekinoroji anokwereta kuvepo kwawo kumagetsi, kubva painternet uye kutaurirana kweserura kumakomputa nemaseva.Electronics inzvimbo yakakura inematavi mazhinji.Ichi chinyorwa chinokudzidzisa nezve yakakosha dhijitari mudziyo wemagetsi unozivikanwa seCPLD (Complex Programmable Logic Device).

Evolution yeDigital Electronics

Electronicsinzvimbo yakaoma ine zviuru zvemidziyo yemagetsi uye zvikamu zviripo.Nekudaro, kutaura zvakanyanya, zvigadzirwa zvemagetsi zviri mumapoka maviri makuru:analog uye digital.

Mumazuva ekutanga emagetsi tekinoroji, maseketi aive akafanana, senge ruzha, chiedza, voltage, uye ikozvino.Nekudaro, mainjiniya emagetsi akakurumidza kuona kuti analog maseketi akaomarara kugadzira uye anodhura.Iko kudiwa kwekukurumidza kuita uye nekukurumidza kutendeuka-nguva kwakatungamira mukuvandudzwa kwemagetsi edhijitari.Nhasi anenge ese mudziyo wekombuta uripo unosanganisira dijitari ICs uye processors.Munyika yemagetsi, masisitimu edhijitari atotsiva zvachose emagetsi eanalog nekuda kwemutengo wakaderera, ruzha rwakaderera, zviri nani.chiratidzo chekuvimbika, kushanda kwepamusoro, uye kuderera kuoma.

Kusiyana nehuwandu husingagumi hwemazinga e data muchiratidzo cheanalog, chiratidzo chedhijitari chinongori nemazinga maviri epfungwa (1s uye 0s).

Mhando dzeDigital Electronic Devices

Iwo ekutanga emagetsi edhijitari aive akapusa uye aingova neashoma emagedhi epfungwa.Nekudaro, nekufamba kwenguva, kuomarara kwemaseketi edhijitari kwakawedzera nekudaro, kurongeka kwakava chinhu chakakosha chemazuva ano edhijitari dhizaini.Makirasi maviri akasiyana emidziyo yedhijitari akabuda kuti ape programmability.Kirasi yekutanga yaive neyakagadziriswa hardware dhizaini ine reprogrammable software.Mienzaniso yemidziyo yakadaro inosanganisira microcontrollers uye microprocessors.Kirasi yechipiri yemidziyo yedhijitari yakaratidza gadziriso yehardware kuti iwane inochinjika logic yedunhu dhizaini.Mienzaniso yemidziyo yakadai inosanganisira FPGAs, SPLDs, uye CPLDs.

Iyo microcontroller chip inoratidzira yakagadziriswa yedhijitari logic yedunhu isingagone kugadziridzwa.Nekudaro, kurongeka kunowanikwa nekushandura software/firmware inomhanya pane microcontroller chip.Kusiyana neizvi, PLD (programmable logic device) ine akawanda logic masero ayo anobatana anogona kugadzirwa uchishandisa HDL (hardware tsananguro mutauro).Naizvozvo, akawanda logic maseketi anogona kuwanikwa uchishandisa PLD.Nekuda kweizvi, kuita uye kumhanya kwePLDs kunowanzo kukwirira kune iyo microcontrollers uye microprocessors.PLDs inopawo vagadziri vedunhu vane hukuru hukuru hwerusununguko uye kuchinjika.

Maseketi akabatanidzwa anoitirwa kudzora dhijitari uye masaini kugadzirisa anowanzo sanganisira processor, logic sedunhu, uye ndangariro.Imwe neimwe yeaya mamodule inogona kuwanikwa uchishandisa akasiyana matekinoroji.

Nhanganyaya kuCPLD

Sezvambokurukurwa, marudzi akati wandei ePLDs (programmable logic devices) aripo, akadai seFPGA, CPLD, uye SPLD.Musiyano wekutanga pakati pezvishandiso izvi uri mukuomarara kwedunhu uye huwandu hweanowanikwa logic masero.Iyo SPLD inowanzo umbwa nemazana mashoma emagedhi, nepo CPLD ine zviuru zvishoma zvemagedhi emagetsi.

Panyaya yekuoma, CPLD (yakaoma programmable logic mudziyo) iri pakati peSPLD (yakareruka programmable logic mudziyo) neFPGA uye nekudaro, inogara nhaka maficha kubva kune zvese izvi zvishandiso.MaCPLD akaoma kunzwisisa kupfuura maSPLD asi asina kuoma kupfuura maFPGA.

MaSPLD anonyanya kushandiswa anosanganisira PAL (programmable array logic), PLA (programmable logic array), uye GAL (generic array logic).PLA ine imwe UYE ndege uye imwe OR ndege.Iyo Hardware tsananguro chirongwa chinotsanangura kubatanidzwa kweidzi ndege.

PAL yakafanana nePLA zvisinei, kune imwe chete ndege inorongeka pachinzvimbo chembiri (AND ndege).Nekugadzirisa imwe ndege, iyo hardware yakaoma inoderedza.Zvisinei, iyi bhenefiti inowanikwa pamutengo wekuchinja.

CPLD Architecture

CPLD inogona kutariswa seshanduko yePAL uye ine akawanda PAL zvimiro zvinozivikanwa semacrocell.MuCPLD package, ese mapini ekupinza anowanikwa kune yega macrocell, nepo macrocell imwe neimwe ine yakatsaurirwa pini yekubuda.

Kubva padhizaini yebhuroka, isu tinogona kuona kuti CPLD ine akawanda macrocell kana mabhuroki ebasa.Iwo macrocells akabatana kuburikidza neinorongwa yekubatanidza, iyo inonzi zvakare GIM (global interconnection matrix).Nekugadzirisazve iyo GIM, akasiyana logic maseketi anogona kuitika.MaCPLD anodyidzana nenyika yekunze vachishandisa dijitari I/Os.

Musiyano pakati peCPLD neFPGA

Mumakore achangopfuura, maFPGA akave akakurumbira mukugadzirwa kwemaprogrammable digital system.Pane zvakawanda zvakafanana pamwe nekusiyana pakati peCPLD neFPGA.Kana zviri zvekufanana, zvese zviri programmable logic zvishandiso zvinosanganisira logic gedhi arrays.Midziyo miviri iyi yakarongwa uchishandisa maHDL akadai seVerilog HDL kana VHDL.

Musiyano wekutanga pakati peCPLD neFPGA uri muhuwandu hwemagedhi.A CPLD ine zviuru zvishoma zvemagedhi emagetsi, nepo huwandu hwemagedhi muFPGA hunogona kusvika kumamiriyoni.Naizvozvo, masekete akaomesesa uye masisitimu anogona kuwanikwa uchishandisa FPGAs.Iyo yakaderera yekuoma uku imari yepamusoro.Nekudaro, maCPLD akanyanya kukodzera kune mashoma akaomarara maapplication.

Mumwe mutsauko wakakosha pakati pezvishandiso zviviri izvi ndewekuti CPLDs inoratidzira yakavakirwa-mukati-isina kuvhurika EEPROM (yemagetsi erasable programmable random-access memory), nepo FPGAs inoratidzira inoshanduka ndangariro.Nekuda kweizvi, CPLD inogona kuchengetedza zvirimo kunyangwe ichidzimwa, nepo FPGA isingakwanise kuchengetedza zvirimo.Uyezve, nekuda kweyakavakirwa-mukati-isina-inotenderera ndangariro, CPLD inogona kutanga kushanda nekukurumidza mushure mesimba-kumusoro.Mazhinji maFPGA, kune rumwe rutivi, anoda zvishoma-rukova kubva kune yekunze isiri-inotenderera ndangariro yekutanga-up.

Panyaya yekuita, maFPGA ane kunonoka kusinga fungidzike kugadzirisa nekuda kwekunyanya kuomesesa zvivakwa zvakasanganiswa neyemushandisi tsika hurongwa.MuCPLDs, iyo pini-ku-pini kunonoka idiki zvakanyanya nekuda kwekureruka kwekuvaka.Iko kunonoka kwekugadzirisa chiratidzo kunokosha kutariswa mukugadzirwa kwekuchengetedza-yakakosha uye yakamisikidzwa chaiyo-nguva zvikumbiro.

Nekuda kweakakwira mafrequency ekushanda uye akaomesesa mashandiro ekuita, mamwe maFPGA anogona kushandisa simba rakawanda kupfuura maCPLD.Nekudaro, kutonga kwekupisa chinhu chakakosha chekutarisa muFPGA-yakavakirwa masisitimu.Nekuda kwechikonzero ichi, FPGA yakavakirwa masisitimu anowanzo shandisa ekupisa kunyura uye kutonhora mafeni uye inoda akakura, akaomarara emagetsi emagetsi uye kugovera network.

Kubva pane ruzivo rwekuchengetedza ruzivo, maCPLD akachengeteka zvakanyanya sezvo chiyeuchidzo chinovakwa mu chip pachayo.Kusiyana neizvi, mazhinji maFPGA anoda ekunze asina-inotenderera ndangariro, inogona kuve yekutyisidzira kuchengetedza data.Kunyangwe data encryption algorithms ari muFPGAs, CPLDs dzakachengetedzeka zvakanyanya mukuenzanisa neFPGAs.

Zvikumbiro zveCPLD

MaCPLD anowana mashandiro avo mune akawanda akaderera-kusvika-yepakati kuomarara dhijitari kudzora uye masaini ekugadzirisa maseketi.Zvimwe zvezvishandiso zvakakosha zvinosanganisira:

1. CPLDs inogona kushandiswa semabootloaders eFPGA uye mamwe anorongwa masisitimu.
2. CPLDs anowanzo shandiswa sekero decoder uye tsika mamiriro emuchina mumadhijitari masisitimu.
3. Nekuda kwehukuru hwavo hudiki uye kuderera kwesimba rekushandisa, maCPLDs akanakira kushandiswa mune inotakurika uyeakabata ruokomadivayiri edhijitari.
4. CPLDs anoshandiswawo mukuchengetedza-yakakosha kutonga maapplication.
