LCMXO2-2000HC-4TG144C Umuzenguruko wuzuye

Gishya kandi cyumwimerere LCMXO2-2000HC-4TG144C Igizwe numuzunguruko wuzuye Ishusho

ibisobanuro bigufi:

Umuryango wa MachXO2 ya ultra power power, ako kanya, kuri PLDs idahindagurika ifite ibikoresho bitandatu bifite ubucucike buri hagati ya 256 na 6864 Reba-Imbonerahamwe (LUT).Usibye LUT ishingiye, igiciro gito cya programable logique ibi bikoresho biranga Embedded Block RAM (EBR), RAM yagabanijwe, Umukoresha Flash Memory (UFM), Phase Locked Loops (PLLs), isoko ya injeniyeri yambere ikomatanya I / O inkunga, iboneza ryambere inkunga harimo ubushobozi bwa boot-boot hamwe na verisiyo ikomye yimikorere isanzwe ikoreshwa nka SPI mugenzuzi, I.²C umugenzuzi nigihe / igihe.Izi fea zituma ibyo bikoresho bikoreshwa mugiciro gito, umuguzi mwinshi hamwe na sisitemu ya porogaramu.

Intangiriro

Field programable gate gate array, nigicuruzwa cyiterambere ryiterambere hashingiwe kubikoresho bishobora gutegurwa nka PAL, GAL, CPLD nibindi.Iragaragara nkigice cya kabiri cyumuzunguruko murwego rwimikorere yihariye ihuriweho (ASICs), idakemura gusa ibitagenda neza byumuzunguruko wabigenewe, ariko kandi inesha ibitagenda neza byumubare muto wibikoresho byumwimerere byinjizwamo amarembo.

Ihame ry'akazi

FPGA yakiriye igitekerezo gishya cya logique selile array LCA (Logic Cell Array), ikubiyemo ibice bitatu: iboneza rya logique module CLB, ibisohoka byinjira module IOB (Ibisohoka byinjira) hamwe nu guhuza imbere (Interconnect).Ibintu byingenzi biranga FPGAs ni:
1) Ukoresheje FPGA mugushushanya imirongo ya ASIC, abayikoresha ntibakeneye kubyara chip kugirango babone chip ikwiye.
2) FPGA irashobora gukoreshwa nkicyitegererezo cyikigereranyo cyizindi zuzuye cyangwa igice cyihariye cya ASIC.
3) FPGA ifite ubutunzi bwa flip-flops na I / O imbere.
4) FPGA ni kimwe mu bikoresho bifite inzinguzingo ngufi ngufi, igiciro gito cyiterambere ndetse ningaruka nkeya mumuzunguruko wa ASIC.
5) FPGA ikoresha inzira yihuse ya CHMOS, gukoresha ingufu nke, kandi irashobora guhuzwa nurwego rwa CMOS na TTL.
Birashobora kuvugwa ko chip ya FPGA nimwe muburyo bwiza bwo guhitamo sisitemu ntoya yo kunoza sisitemu no kwizerwa.

FPGA yateguwe na porogaramu ibitswe muri chip ya RAM kugirango ishyireho imikorere yayo, bityo RAM ya chip ikeneye gutegurwa mugihe ikora.Abakoresha barashobora gukoresha uburyo butandukanye bwo gutangiza gahunda ukurikije uburyo butandukanye.

Iyo power-on, chip ya FPGA isoma amakuru yo muri EPROM muri RAM ya progaramu ya chip, hanyuma iboneza rirangiye, FPGA yinjira muri reta ikora.Imbaraga zimaze kubura, FPGA isubira kumpapuro zera, kandi umubano wimbere wimbere urazimira, bityo FPGA irashobora gukoreshwa inshuro nyinshi.Porogaramu ya FPGA ntisaba porogaramu yihariye ya FPGA, gusa intego-rusange ya EPROM na PROM.Mugihe ukeneye guhindura imikorere ya FPGA, hindura gusa EPROM.Muri ubu buryo, FPGA imwe, amakuru atandukanye yo gutangiza gahunda, irashobora kubyara imikorere itandukanye.Kubwibyo, gukoresha FPGAs biroroshye cyane.

Uburyo bw'imiterere

FPGA ifite uburyo butandukanye bwiboneza: uburyo bukuru bubangikanye ni FPGA wongeyeho EPROM;Umwigisha-imbata arashobora gushyigikira porogaramu imwe ya PIECE PROM FPGA nyinshi;Uburyo bukurikirana bushobora gutegurwa hamwe na PROM FPGA;Uburyo bwa periferique butuma FPGA ikoreshwa nka peripheri ya microprocessor, yateguwe na microprocessor.

Ibibazo nko kugera ku gihe cyihuse cyo gufunga, kugabanya gukoresha ingufu nigiciro, guhindura imicungire yisaha, no kugabanya ubunini bwibishushanyo bya FPGA na PCB byahoze ari ibibazo byingenzi kubashakashatsi ba sisitemu bakoresheje FPGAs.Uyu munsi, mugihe FPGAs igenda yerekeza ku bucucike buri hejuru, ubushobozi bwinshi, gukoresha ingufu nke, hamwe no kurushaho guhuza IP, abashakashatsi ba sisitemu bungukirwa nibikorwa byiza mugihe bahuye nibibazo bishya byubushakashatsi bitewe nurwego rutigeze rubaho rwimikorere nubushobozi bwa FPGAs.
