2. Ama-FPGA ochungechunge lwe-Spartan ngezindleko eziphansi

Uchungechunge lwe-Spartan lufanele izinkambu ezijwayelekile zezimboni nezentengiso, futhi ama-chips ajwayelekile amanje afaka i-Spartan-2, i-Spartan-2E, i-Spartan-3, i-Spartan-3A, i-Spartan-3E, ne-Spartan-6.

I-Spartan-2 izuza izinsiza ezinengqondo ezengeziwe kusukela kuchungechunge lwe-Spartan, futhi ukuminyana kwe-chip kungafika kumasango esistimu angu-200,000 ukuze kuzuzwe ukusebenza okuphezulu.Ngenxa yesakhiwo se-FPGA esivuthiwe, esisekela izindinganiso zokusebenzelana ezithandwayo, nenani elifanele lezinsiza ezinengqondo ne-RAM eku-chip, nokuhlinzeka ngokucubungula kwewashi okuguquguqukayo, ingakwazi ukusebenzisa i-8-bit PicoBlaze softcore futhi isetshenziswa kakhulu emikhiqizweni ehlukahlukene esezingeni eliphansi. .

Uchungechunge lwe-Spartan-2E lusekelwe ekwakhiweni kwe-Virtex-E, enamasango anengqondo amaningi, i-I/O yomsebenzisi nokusebenza okuphezulu kune-Spartan-2.I-Xilinx iphinde ihlinzeke ngama-IP cores afaka isilawuli sememori, isixhumi esibonakalayo sesistimu, i-DSP, ukuxhumana, nenethiwekhi, futhi ingasebenzisa ama-CPU athambile ama-cores ngokusekelwa okuthile kwe-DSP.

Uchungechunge lwe-Spartan-3 lusekelwe ekwakhiweni kwe-Virtex-II FPGA enobuchwepheshe be-90nm, inqubo yensimbi enezingqimba eziyisi-8, amasango esistimu angaphezu kwezigidi ezi-5, isiphindaphindi esishunyekiwe esiqinile, kanye nemojula yokuphatha iwashi ledijithali.Ngokwezakhiwo, i-Spartan-3 ihlanganisa ingqondo, inkumbulo, ukusebenza kwezibalo, ama-digital processor processors, i-I/O, nezinsiza zokuphatha uhlelo ngendlela ephelele ukuze kunikwe amandla izinhlelo zokusebenza ezisezingeni eliphezulu nezibanzi, ukuzuza impumelelo kwezohwebo nokuba nesabelo esikhulu sabaphansi nabaphansi. imakethe yebanga eliphakathi.

Uchungechunge lwe-Spartan-3E luyintuthuko eyengeziwe empumelelweni ye-Spartan-3, enikeza amachweba e-I/O amaningi kanye nezindleko eziphansi zeyunithi kune-Spartan-3, okulenza libe yi-FPGA chip engabizi kakhulu evela ku-Xilinx.Ngokusetshenziswa kangcono kobuchwepheshe be-90nm kanye nezici ezengeziwe kanye nokucubungula umkhawulokudonsa ngeyunithi ngayinye yezindleko, iwumkhiqizo omusha obiza kancane omele i-Xilinx kanye nenye indlela ephumelelayo yama-ASIC, ikakhulukazi izinhlelo zokusebenza ze-electronics zabathengi ezifana nokufinyelela okungenantambo kwe-broadband, ukufinyelela kwenethiwekhi yasekhaya, kanye amadivaysi e-TV edijithali.

Umndeni wakwa-Spartan-3A wakhela phezu kwenkundla ye-Spartan-3 kanye ne-Spartan-3E futhi uhlanganise izici ezihlukahlukene ezintsha ezisiza amakhasimende ehlise ngokuphawulekayo izindleko eziphelele zesistimu.Ubuchwepheshe be-DNA ID yedivayisi eyingqayizivele buvumela inombolo yokuqala ye-FPGA electronic serial number;inikeza indlela eyongayo nenamandla yokuvimbela ukuphazamisa, ukuhlanganisa, kanye nokuklama ngokweqile;izici ezithuthukisiwe zokuqala eziningi ngokuqapha okuhlanganisiwe kwe-watchdog, futhi isekela inkumbulo ye-flash yokuhweba ukusiza ukunciphisa izindleko zesistimu.

Uchungechunge lwe-Spartan-6 alunawo amandla okuhlanganiswa kwesistimu ehamba phambili embonini kuphela kodwa futhi lunezindleko eziphansi kakhulu eziphelele zobunikazi bezicelo zevolumu ephezulu;uchungechunge lunamalungu ayi-13 futhi lutholakala ngokuminyana kusukela kumaseli anengqondo angu-3,840 kuya kumaseli anengqondo angu-147,443.Ikhiqizwe kusetshenziswa ubuchwepheshe benqubo yethusi obufakazelwe obungu-45nm obunamandla aphansi, umndeni wakwa-Spartan-6 unikeza ibhalansi ephelele yentengo/ukusebenza namandla asetshenziswayo, ingqondo entsha nesebenza kahle kakhudlwana ye-double-register 6-input lookup table (LUT), kanye nesethi ecebile ye amamojula esistimu eyakhelwe ngaphakathi, afaka u-18KB Vimba i-RAM.amamojula, afaka i-18KB Block RAM, isizukulwane sesibili se-DSP48A1 Slice, isilawuli sememori ye-SDRAM, imojula yokuphatha iwashi yemodi exubile, ubuchwepheshe be-SelectIO, imojula ye-serial transceiver eyenziwe ngamandla ngamandla, i-PCI Express® imoduli yokuphela ehambisanayo, ukuphathwa kwamandla okuthuthukile kwesistimu. izindlela, izinketho zokumisa ezihlonza ngokuzenzakalelayo, kanye nokuphepha kwe-IP Okuthuthukisiwe nge-AES nokuvikelwa kwe-DNA Yedivayisi.

Ama-FPGA e-Spartan-6 ahlinzeka ngesixazululo esilungile semiklamo enengqondo yevolumu ephezulu, imiklamo ye-DSP egxile kubathengi, kanye nezinhlelo zokusebenza ezishumekiwe ezingazweli kakhulu.Ama-FPGA e-Spartan-6 ahlinzeka ngesisekelo esiqinile se-silicon esihlelekayo sezinkundla eziqondiwe ezinikezela ngezingxenyekazi zekhompiyutha ezididiyelwe nezingxenye zesofthiwe ukuvumela abaklami ukuthi bagxile emisha kusukela ekuqaleni kwemizamo yokuthuthukisa.
