1. Virtex jerin FPGAs don babban aiki

Jerin Virtex shine babban samfurin Xilinx kuma babban samfuri a cikin masana'antar.Xilinx ya ci kasuwa tare da samfuran jerin samfuran sa na Virtex, don haka ya sami matsayi a matsayin babban mai samar da FPGA.Ana iya cewa Xilinx yana jagorantar masana'antar tsararrun ƙofa mai shirye-shirye tare da dangin Virtex na samfuran FPGA.An yi niyya ne ga aikace-aikace kamar kayan aikin sadarwa, masana'antar kera motoci, da manyan kayan lantarki na mabukaci.Chips ɗin na yau da kullun sun haɗa da Vitrex-2, Virtex-2 Pro, Virtex-4, Virtex-5, Virtex-6, da nau'ikan Virtex-7.

An gabatar da jerin Virtex-2 a cikin 2002 tare da tsarin 0.15nm, ƙarfin lantarki na 1.5V, agogon aiki har zuwa 420MHz, goyan bayan fiye da 20 I / O ƙa'idodin dubawa, cikakken ikon sarrafa agogon tsarin, da ginanniyar tushen tushen IP mai wuya. fasaha mai mahimmanci wanda ke ba da damar ƙananan igiyoyin IP masu wuya a sanya su a ko'ina a kan guntu, tare da ƙarin albarkatu da mafi girma fiye da jerin Virtex.mafi girman aiki fiye da dangin Virtex.

Tsarin Virtex-2 Pro yana ginawa akan Virtex-2 tare da ingantaccen ƙarfin sarrafa kayan aiki, da kuma shigar da kayan kwalliyar PowerPC405, kuma ya haɗa da fasahar Interconnect na ci gaba don magance ƙalubalen da ke fuskantar manyan ayyuka, ban da ƙari na babban sauri. serial transceiver don samar da Gigabit Ethernet mafita.

Iyalin Virtex-4 sun dogara ne akan Advanced Silicon Block Combination Module (ASMBL), wanda ke nuna babban ma'auni mai mahimmanci tare da mitocin agogo har zuwa 500 MHz;tare da nau'ikan DCM, PMCD-madaidaicin lokaci-lokaci masu rarraba, hanyoyin sadarwar agogo daban-daban akan guntu;Fasahar SmartRAM na 500 MHz tare da haɗaɗɗiyar dabarar sarrafa FIFO, kuma kowane I/O an haɗa shi tare da fasahar daidaita tushen tushen ChipSync don 1 Gbps I/O da Xtreme DSP logic guntu.Masu zane-zane na iya zaɓar nau'ikan tsarin Virtex-4 daban-daban bisa ga buƙatun su, don ƙira-ƙira mai ƙarfi: Virtex-4 LX, don aikace-aikacen sarrafa siginar babban aiki: Virtex-4 SX, don haɗin haɗin sauri mai sauri da aikace-aikacen sarrafa kayan aiki: Virtex- 4 FX.Iyalin Virtex-4 suna ba da babban ci gaba a cikin duk ma'auni akan VirtexII Tsarin Virtex-4, wanda ke cikin samarwa da yawa tun ƙarshen 2005, ya maye gurbin VirtexII, VirtexII-Pro, kuma shine mafi mahimmancin samfurin Xilinx a cikin babban yau. -karshen kasuwar FPGA.

Iyalin Virtex-5 sun dogara ne akan fasahar tsarin jan karfe na zamani na 65nm na zamani kuma suna amfani da tsarin gine-gine na ASMBL (Advanced Silicon Building Block) na ƙarni na biyu, wanda ya ƙunshi dandamali daban-daban guda biyar (ƙarannai).Kowane dandali ya ƙunshi nau'ikan fasali daban-daban don saduwa da buƙatun ƙira-ƙirar dabaru da yawa.Bugu da ƙari ga tsarin gine-ginen fasaha na zamani, Virtex-5 FPGAs sun haɗa da nau'o'in nau'i-nau'i iri-iri na tsarin tsarin IP, ciki har da 36 Kb Block RAM / FIFO mai ƙarfi, 25 × 18 na biyu. Slice DSP, Fasahar SelectIO tare da ginanniyar CNC impedance, ChipSync tushen kayan aikin haɗin gwiwar aiki tare, aikin saka idanu na tsarin, da haɗaɗɗen DCM (Mai sarrafa agogo na Dijital) da PLL (Phase Locked Loop) janareta na agogo, da zaɓuɓɓukan daidaitawa na ci gaba.Wasu fasalulluka na tushen dandamali sun haɗa da ingantaccen tsarin siriyal mai saurin sauri mai ƙarfi don haɓaka haɗin haɗin kai, haɗaɗɗen ƙirar PCI Express mai dacewa da ƙarshen, madaidaicin Ethernet MAC (mai kula da samun damar watsa labarai), da babban aikin PowerPC 440 microprocessor. tsarin da aka haɗa wanda ke ba masu ƙirƙira dabaru damar haɓaka mafi girman matakan aiki a cikin tsarin tushen su na FPGA.

Iyalin Virtex-6 suna ba da sabbin abubuwa, mafi ci gaba ga kasuwar FPGA.Virtex-6 FPGAs sune tushen fasahar silicon da za'a iya tsarawa don wuraren gwajin da aka yi niyya waɗanda ke ba da kayan aiki da kayan aikin software don taimakawa masu ƙira su mai da hankali kan ƙirƙira da zarar an fara ƙoƙarin haɓakawa.Iyalin Virtex-6 suna fasalta tsarin gine-ginen ginshiƙan ASMBL na ƙarni na uku (modulun siliki mai haɓakawa) wanda ya haɗa da dangi daban-daban.Wannan bayyani yana bayyana na'urori a cikin ƙananan gidaje na LXT, SXT, da HXT.Kowane dangi yana ƙunshe da nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan ƙira na ƙirƙira na ƙira.Baya ga masana'anta na dabaru masu girma, Virtex-6 FPGAs sun haɗa da ginanniyoyin matakan-tsari da yawa.Waɗannan fasalulluka suna ba masu ƙirƙira dabaru damar gina mafi girman matakan aiki da ayyuka cikin tsarin FPGA ɗinsu.Virtex-6 FPGAs kuma suna ba da mafita mafi kyau don saduwa da buƙatun masu zane-zanen dabaru masu mahimmanci, manyan masu zanen kaya na DSP, da manyan kayan aikin da aka saka na tsarin, suna kawo dabaru waɗanda ba a taɓa gani ba, DSP, haɗin kai, da ƙarfin microprocessor mai taushi.

Virtex-7 shine samfurin FPGA mai ɗorewa wanda aka gabatar a cikin 2011 akan tsarin 28nm wanda ke ba abokan ciniki 'yanci don ɓoyewa da ɓarna abubuwan da ke rage farashi da amfani da wutar lantarki yayin haɓaka aiki da iya aiki, ta haka rage haɓaka haɓakawa da saka hannun jari ga duka ƙasƙanci. - tsada da manyan ayyuka iyalai.Bugu da ƙari, an tabbatar da raguwar farashin 35% idan aka kwatanta da Virtex-6 ba tare da haɓaka haɓakawa ko zuba jarurruka na injiniya ba, ƙara yawan yawan aiki.
