1. Virtex mndandanda wa FPGA wochita bwino kwambiri

Mndandanda wa Virtex ndi mankhwala apamwamba kwambiri a Xilinx komanso apamwamba kwambiri pamsika.Xilinx wapambana msika ndi zinthu zake za Virtex, motero adapeza udindo wotsogolera FPGA.Titha kunena kuti Xilinx amatsogolera makampani opanga zipata zapakhomo ndi banja lake la Virtex lazinthu za FPGA.Imayang'aniridwa kwambiri ndi ntchito monga ma telecom, makampani amagalimoto, komanso zida zamagetsi zogula kwambiri.Ma chips omwe alipo tsopano akuphatikizapo Vitrex-2, Virtex-2 Pro, Virtex-4, Virtex-5, Virtex-6, ndi Virtex-7.

Mndandanda wa Virtex-2 unayambitsidwa mu 2002 ndi ndondomeko ya 0.15nm, 1.5V core voltage, mawotchi ogwiritsira ntchito mpaka 420MHz, chithandizo cha mawonekedwe oposa 20 I / O, mphamvu zonse zoyendetsera mawotchi, komanso IP core hard ukadaulo wapakatikati womwe umalola ma cores olimba a IP kuti agawidwe kulikonse pa chip, ndi zinthu zambiri komanso magwiridwe antchito apamwamba kuposa mndandanda wa Virtex.magwiridwe antchito apamwamba kuposa banja la Virtex.

Mndandanda wa Virtex-2 Pro umamanga pa Virtex-2 yokhala ndi luso lokhazikika lokhazikika, ndi ma cores ophatikizidwa a PowerPC405, ndipo imaphatikizapo ukadaulo wapamwamba wa Active Interconnect kuthana ndi zovuta zomwe machitidwe ochita bwino kwambiri, kuphatikiza kuwonjezera pa liwiro lalikulu. serial transceiver kuti apereke mayankho a Gigabit Ethernet.

Banja la Virtex-4 limachokera ku Advanced Silicon Block Combination Module (ASMBL) yomangamanga, yomwe imakhala ndi kachulukidwe kapamwamba kamene kali ndi mawotchi othamanga mpaka 500 MHz;okhala ndi ma module a DCM, magawo ofananira ndi mawotchi a PMCD, maukonde a wotchi yapa-chip;Ukadaulo wa 500 MHz SmartRAM wokhala ndi malingaliro ophatikizika a FIFO, ndipo I/O iliyonse imaphatikizidwa ndiukadaulo wa ChipSync source synchronization wa 1 Gbps I/O ndi Xtreme DSP logic chip.Okonza amatha kusankha ma subsystems osiyanasiyana a Virtex-4 malinga ndi zosowa zawo, pamapangidwe ozama kwambiri: Virtex-4 LX, pakugwiritsa ntchito ma siginecha apamwamba kwambiri: Virtex-4 SX, yolumikizira ma serial othamanga kwambiri komanso mapulogalamu ophatikizidwa: Virtex- 4 FX pa.Banja la Virtex-4 limapereka kusintha kwakukulu pamametric onse pa VirtexII Mndandanda wa Virtex-4, womwe wakhala ukupangidwa mochuluka kuyambira kumapeto kwa 2005, walowa m'malo mwa VirtexII, VirtexII-Pro, ndipo ndi chinthu chofunikira kwambiri cha Xilinx masiku ano. -kumapeto kwa msika wa FPGA.

Banja la Virtex-5 lakhazikitsidwa paukadaulo wapamwamba kwambiri wa 65nm wamkuwa ndipo limagwiritsa ntchito zomanga zamtundu wa ASMBL (Advanced Silicon Building Block), zomwe zili ndi nsanja zisanu (mabanja ang'onoang'ono).Pulatifomu iliyonse imakhala ndi magawo osiyanasiyana kuti ikwaniritse zosowa zamapangidwe apamwamba kwambiri.Kuphatikiza pa zomangamanga zamakono zamakono, Virtex-5 FPGAs imaphatikizapo ma modules osiyanasiyana olimba a IP, kuphatikizapo 36 Kb Block RAM / FIFO yamphamvu, yachiwiri ya 25 × 18. DSP Slice, teknoloji ya SelectIO yokhala ndi CNC impedance, ChipSync source synchronization interface modules, system monitor performance, ndi DCM (Digital Clock Manager) yophatikizidwa ndi mawotchi a PLL (Phase Locked Loop), ndi zosankha zapamwamba.Zina zozikidwa pa pulatifomu ndi monga gawo la transceiver lamphamvu kwambiri lamphamvu kwambiri lothandizira kulumikizidwa kwa serial, gawo lophatikizika la PCI Express-compatible endpoint, tri-state Ethernet MAC (media access controller), ndi mphamvu yapamwamba ya PowerPC 440 microprocessor. module yophatikizidwa yomwe imathandizira opanga malingaliro apamwamba kuti akhale ndi magwiridwe antchito apamwamba kwambiri pamakina awo a FPGA.

Banja la Virtex-6 limapereka zaposachedwa, zapamwamba kwambiri pamsika wa FPGA.Virtex-6 FPGAs ndi maziko okonzekera ukadaulo wa silicon pamayesero omwe amayang'ana omwe amapereka zida zamapulogalamu ndi mapulogalamu kuti athandizire opanga kuyang'ana kwambiri zaukadaulo akangoyamba ntchito zachitukuko.Banja la Virtex-6 lili ndi m'badwo wachitatu wa ASMBL (module ya silicon portfolio module) yomanga yomwe imaphatikizapo mabanja angapo osiyanasiyana.Izi mwachidule zikufotokozera zida zomwe zili m'mabanja ang'onoang'ono a LXT, SXT, ndi HXT.Banja laling'ono lililonse limakhala ndi zophatikizira zosiyanasiyana kuti zikwaniritse zofunikira zosiyanasiyana zamapangidwe apamwamba.Kuphatikiza pa nsalu zomveka zogwira ntchito kwambiri, Virtex-6 FPGAs imaphatikizapo ma module angapo omangika.Izi zimathandizira opanga malingaliro kupanga magwiridwe antchito apamwamba kwambiri pamakina awo a FPGA.Ma Virtex-6 FPGAs amaperekanso yankho labwino kwambiri kuti akwaniritse zosowa za opanga malingaliro apamwamba kwambiri, opanga ma DSP apamwamba kwambiri, komanso opanga makina ophatikizika apamwamba kwambiri, kubweretsa malingaliro, DSP, kulumikizana, ndi kuthekera kofewa kwa microprocessor.

Virtex-7 ndi chinthu chapamwamba kwambiri cha FPGA chomwe chinayambika mu 2011 pa njira ya 28nm yomwe imapatsa makasitomala ufulu womasuka ndi kumasula zinthu zomwe zimachepetsa mtengo ndi kugwiritsa ntchito mphamvu pamene zikuwonjezera ntchito ndi mphamvu, motero kuchepetsa chitukuko ndi kutumizira ndalama zotsika mtengo. -mabanja okwera mtengo komanso ochita bwino kwambiri.Kuphatikiza apo, kutsika mtengo kwa 35% poyerekeza ndi Virtex-6 kumatsimikiziridwa popanda kutembenuka kowonjezereka kapena kuyika ndalama zauinjiniya, kukulitsa zokolola.
