Isekethe entsha neyoqobo ye-LCMXO2-2000HC-4TG144C Isithombe Esifakiwe

incazelo emfushane:

Umndeni wakwa-MachXO2 wamandla aphansi kakhulu, ama-PLD asebenza ngokushesha, angaguquguquki unamadivayisi ayisithupha anokuminyana ukusuka ku-256 kuya ku-6864 Look-Up Tables (LUTs).Ngokungeziwe kulokho okusekelwe ku-LUT, okunezindleko eziphansi okuhlelekayo lawa madivayisi afaka i-Embedded Block RAM (EBR), i-RAM Esabalalisiwe, Imemori Yenkumbulo Yomsebenzisi (UFM), I-Phase Locked Loops (PLLs), ukusekelwa komthombo ovunyelaniswe ngaphambilini we-I/O, ukucushwa okuthuthukisiwe. ukwesekwa okuhlanganisa amandla ebhuthi ekabili nezinguqulo eziqinile zemisebenzi evame ukusetshenziswa njengesilawuli se-SPI, I²C isilawuli nesikhathi/ikhawunta.Lezi zici zivumela lezi zisetshenziswa ukuthi zisetshenziswe ngezindleko eziphansi, umthengi ophezulu kanye nezinhlelo zokusebenza zesistimu.

Isingeniso

Uhlu lwamasango ahlelekayo, okuwumkhiqizo wokuthuthuka okuqhubekayo ngesisekelo samadivayisi ahlelekayo afana ne-PAL, GAL, CPLD njalonjalo.Kuvela njengesekhethi evamile emkhakheni wamasekethe ahlanganisiwe aqondene nohlelo lokusebenza (ama-ASIC), angaxazululi kuphela ukushiyeka kwamasekhethi angokwezifiso, kodwa futhi enqoba ukushiyeka kwenombolo ekhawulelwe yamasekhethi esango langempela ledivayisi ehlelekayo.

Isimiso Sokusebenza

I-FPGA yamukela umqondo omusha we-logic cell array LCA (Logic Cell Array), ehlanganisa izingxenye ezintathu: imojula ye-logic elungisekayo ye-CLB, imojula yokufaka okukhiphayo i-IOB (I-Input Output Block) noxhumo lwangaphakathi (I-Interconnect).Izici eziyisisekelo zama-FPGA yilezi:
1) Ukusebenzisa i-FPGA ukuklama amasekhethi e-ASIC, abasebenzisi abadingi ukukhiqiza ama-chip ukuze bathole i-chip efanelekile.
2) I-FPGA ingasetshenziswa njengesifanekiso somshayeli samanye amasekhethi e-ASIC enziwe ngokwezifiso ngokugcwele noma enziwe ngokwezifiso.
3) I-FPGA inengcebo yama-flip-flops kanye nezikhonkwane ze-I/O ngaphakathi.
4) I-FPGA ingenye yamathuluzi anomjikelezo wokuklama omfushane kakhulu, izindleko zokuthuthukiswa eziphansi kanye nengozi ephansi kakhulu kumjikelezo we-ASIC.
5) I-FPGA yamukela inqubo ye-CHMOS enesivinini esikhulu, ukusetshenziswa kwamandla okuphansi, futhi ingahambisana namazinga e-CMOS ne-TTL.
Kungashiwo ukuthi ama-FPGA chips angenye yezinketho ezinhle kakhulu zezinhlelo ze-batch ezincane ukuthuthukisa ukuhlanganiswa nokuthembeka kwesistimu.

I-FPGA ihlelwe wuhlelo olugcinwe ku-RAM eku-chip ukuze isethe isimo sayo sokusebenza, ngakho-ke i-RAM eku-chip idinga ukuhlelwa lapho isebenza.Abasebenzisi bangasebenzisa izindlela zokuhlela ezihlukene ngokuya ngezindlela zokumisa ezihlukene.

Uma ikhanya, i-chip ye-FPGA ifunda idatha esuka ku-EPROM iye ku-RAM yohlelo lwe-on-chip, futhi ngemva kokuqedwa kokumisa, i-FPGA ingena esimweni sokusebenza.Ngemva kokuphelelwa amandla, i-FPGA ibuyela emashidini amhlophe, futhi ubudlelwano obunengqondo bangaphakathi buyanyamalala, ngakho i-FPGA ingasetshenziswa ngokuphindaphindiwe.Ukuhlelwa kwe-FPGA akudingi umhleli we-FPGA ozinikele, kuphela i-EPROM yenhloso evamile kanye nomhleli we-PROM.Uma udinga ukulungisa umsebenzi we-FPGA, vele ushintshe i-EPROM.Ngale ndlela, i-FPGA efanayo, idatha yokuhlela ehlukene, ingakhiqiza imisebenzi ehlukene yesifunda.Ngakho-ke, ukusetshenziswa kwama-FPGA kuvumelana nezimo kakhulu.

Izindlela zokumisa

I-FPGA inezinhlobonhlobo zezindlela zokumisa: imodi eyinhloko ehambisanayo i-FPGA kanye ne-EPROM;Imodi ye-Master-slave ingasekela uhlelo olulodwa lwe-PIECE PROM lwama-FPGA amaningi;Imodi ye-serial ingahlelwa nge-serial PROM FPGA;Imodi ye-Peripheral ivumela i-FPGA ukuthi isetshenziswe njenge-peripheral ye-microprocessor, ehlelwe yi-microprocessor.

Izinkinga ezinjengokuthola ukuvalwa kwesikhathi ngokushesha, ukwehlisa ukusetshenziswa kwamandla nezindleko, ukuthuthukisa ukuphathwa kwewashi, nokunciphisa inkimbinkimbi yemiklamo ye-FPGA ne-PCB bekulokhu kuyizinkinga ezibalulekile konjiniyela bokuklama isistimu abasebenzisa ama-FPGA.Namuhla, njengoba ama-FPGA eqhubekela ekuminyaneni okuphezulu, umthamo omkhulu, ukusetshenziswa kwamandla okuphansi, nokuhlanganiswa okwengeziwe kwe-IP, onjiniyela bokuklama amasistimu bayazuza kulokhu kusebenza okuphezulu kuyilapho bebhekene nezinselelo ezintsha zokuklama ngenxa yamazinga angakaze abonwe okusebenza nekhono lama-FPGA.
