Inkcazo

Izixhobo ze-Cyclone® ziqulethe umgca we-two-dimensional-kunye ne-column-based architecture ukuphumeza ingqiqo yesiko.Ikholamu kunye noqhagamshelo lwerowu lwezantya ezahlukeneyo zibonelela ngoqhagamshelo lwesignali phakathi kwee-LABs kunye neebhloko zememori ezizinzisiweyo.Uluhlu lwengqiqo lubandakanya ii-LABs, ezinee-LE ezili-10 kwi-LAB nganye.I-LE yiyunithi encinci yengqiqo ebonelela ngokuphunyezwa okusebenzayo kwemisebenzi yengqiqo yomsebenzisi.Ii-LABs zidityaniswe ngokwemiqolo kunye neekholamu kwisixhobo sonke.Izixhobo zenkanyamba ziphakathi kwe-2,910 ukuya kwi-20,060 LEs.Iibhloko ze-RAM ze-M4K ziibhloko zememori ezikwi-double-port eziyinyani ezinamasuntswana enkumbulo e-4K kunye ne-parity (amasuntswana angama-4,608).Ezi bloko zinikezela ngezibuko ezimbini ezizinikeleyo, izibuko ezimbini ezilula, okanye imemori yezibuko enye ukuya kuthi ga kwi-36-bits ububanzi ukuya kuma-250 MHz.Ezi bloko zidityaniswe ngokweekholamu kwisixhobo phakathi kwe-LABs ezithile.Izixhobo ze-Cyclone zibonelela phakathi kwe-60 ukuya kwi-288 Kbits ye-RAM edibeneyo.Isixhobo ngasinye seSitshingitshane se-I/O sityiswa yinto ye-I/O (IOE) ebekwe ekupheleni kwemigca ye-LAB kunye neekholamu ezijikeleze umda wesixhobo.Izikhonkwane ze-I/O zixhasa imigangatho eyahlukeneyo ye-I/O eyodwa kunye neyohlukileyo, efana ne-66- kunye ne-33-MHz, i-64- kunye ne-32-bit ye-PCI esemgangathweni kunye nomgangatho we-LVDS I/O ukuya kuthi ga kwi-640 Mbps.IOE nganye iqulethe i-bidirectional ye-I/O buffer kunye neerejista ezintathu zokubhalisa igalelo, imveliso, kunye neempawu ezivumela ukuphuma.Iinjongo ezimbini ze-DQS, i-DQ, kunye nezikhonkwane ze-DM kunye namatyathanga okulibaziseka (asetyenziselwa ukulungelelanisa izibonakaliso ze-DDR) zibonelela ngenkxaso ye-interface kunye nezixhobo zememori zangaphandle ezifana ne-DDR SDRAM, kunye nezixhobo ze-FCRAM ukuya kwi-133 MHz (266 Mbps).Izixhobo zeCyclone zibonelela ngenethiwekhi yewotshi yehlabathi kunye nokuya kuthi ga kwii-PLL ezimbini.Inethiwekhi yewotshi yehlabathi iqulathe iintambo zewotshi ezisibhozo zehlabathi eziqhuba kuso sonke isixhobo.Inethiwekhi yewotshi yehlabathi inokubonelela ngewotshi kuzo zonke izixhobo ezingaphakathi kwesixhobo, ezinjengee-IOE, ii-LE, kunye neebhloko zememori.Imigca yewotshi yehlabathi ingasetyenziselwa iimpawu zolawulo.Ii-PLL ze-Cyclone zibonelela nge-clocking yenjongo ngokubanzi kunye nokuphindaphinda kwewotshi kunye nokutshintshwa kwesigaba kunye neziphumo zangaphandle zenkxaso ye-I / O ye-speed speed.
