Izimfanelo Zomkhiqizo

1. Virtex uchungechunge FPGAs ukusebenza okusezingeni eliphezulu

Uchungechunge lwe-Virtex luwumkhiqizo osezingeni eliphezulu we-Xilinx kanye nomkhiqizo ophezulu embonini.I-Xilinx iwine imakethe ngemikhiqizo yayo yochungechunge lwe-Virtex, ngaleyo ndlela ithola isikhundla njengomhlinzeki oholayo we-FPGA.Kungashiwo ukuthi i-Xilinx ihola imboni yesango elihlelekayo elihlelekayo nomndeni wayo we-Virtex wemikhiqizo ye-FPGA.Ihloselwe kakhulu izicelo ezifana nengqalasizinda ye-telecom, imboni yezimoto, kanye ne-high-end consumer electronics.Ama-chips amanje ajwayelekile afaka izigaba ze-Vitrex-2, Virtex-2 Pro, Virtex-4, Virtex-5, Virtex-6, kanye ne-Virtex-7.

Uchungechunge lwe-Virtex-2 lwethulwa ngo-2002 ngenqubo engu-0.15nm, i-voltage engu-1.5V eyinhloko, amawashi asebenzayo afika ku-420MHz, ukusekelwa kwamazinga okusebenza angaphezu kwama-20 I/O, amandla okuphatha iwashi lesistimu ephelele, kanye ne-IP eyakhelwe ngaphakathi kanzima. ubuchwepheshe obuyisisekelo obuvumela ama-IP cores aqinile ukuthi anikezwe noma yikuphi ku-chip, enezinsiza eziningi nokusebenza okuphezulu kunochungechunge lwe-Virtex.ukusebenza okuphezulu kunomndeni wakwaVirtex.

Uchungechunge lwe-Virtex-2 Pro lwakha phezu kwe-Virtex-2 enamandla okucubungula ashumekiwe athuthukisiwe, kanye nama-PowerPC405 cores ashunyekiwe, futhi luhlanganisa ubuchwepheshe obuthuthukisiwe be-Active Interconnect ukuze kubhekwane nezinselelo izinhlelo ezisebenza kahle kakhulu ezibhekene nazo, ngaphezu kokwengezwa kwesivinini esikhulu. i-serial transceiver ukuhlinzeka ngezixazululo ze-Gigabit Ethernet.

Umndeni we-Virtex-4 usekelwe ekwakhiweni kwe-Advanced Silicon Block Combination Module (ASMBL), ehlanganisa ukuminyana kwe-logic ephezulu ngamafrikhwensi ewashi afika ku-500 MHz;enamamojula e-DCM, izihlukanisi zewashi ezihambisana nesigaba se-PMCD, amanethiwekhi wewashi ahlukile ku-chip;Ubuchwepheshe be-SmartRAM 500 MHz nobunengqondo ehlanganisiwe yokulawula ye-FIFO, futhi i-I/O ngayinye ihlanganiswe nobuchwepheshe bokuvumelanisa bomthombo we-ChipSync ku-1 Gbps I/O kanye ne-Xtreme DSP logic chip.Abaqambi bangakhetha ama-subsystem ahlukene e-Virtex-4 ngokwezidingo zabo, ngemiklamo enengqondo kakhulu: I-Virtex-4 LX, yezinhlelo zokusebenza ezisebenza kahle kakhulu zokucubungula isignali: I-Virtex-4 SX, yokuxhumeka kwe-serial ngesivinini esiphezulu kanye nezinhlelo zokusebenza zokucubungula ezishumekiwe: I-Virtex- 4 FX.Umndeni wakwa-Virtex-4 unikeza intuthuko enkulu kuwo wonke amamethrikhi ngaphezulu kwe-VirtexII Uchungechunge lwe-Virtex-4, obekukhiqizwa ngobuningi kusukela ekupheleni kuka-2005, luthathe indawo ye-VirtexII, i-VirtexII-Pro, futhi ingumkhiqizo obaluleke kakhulu we-Xilinx kwephezulu yanamuhla. -phela imakethe ye-FPGA.

Umndeni wakwa-Virtex-5 usekelwe kubuchwepheshe besimanjemanje benqubo ye-65nm yethusi futhi usebenzisa i-ASMBL yesizukulwane sesibili (Advanced Silicon Building Block) yezakhiwo zekholomu, eziqukethe amapulatifomu amahlanu ahlukene (imindeni engaphansi).Inkundla ngayinye iqukethe izilinganiso zezici ezihlukene ukuze ihlangabezane nezidingo zamadizayini amaningi anengqondo athuthukile.Ngokungeziwe ekwakhiweni kwe-logic yezinga eliphezulu lokusebenza, i-Virtex-5 FPGAs ihlanganisa amamojula ahlukene wesistimu ye-hard-IP, kuhlanganise ne-36 Kb Block RAM/FIFO enamandla, isizukulwane sesibili esingu-25 × 18. I-DSP Slice, ubuchwepheshe be-SelectIO obunokuvinjwa kwe-CNC eyakhelwe ngaphakathi, amamojula we-ChipSync umthombo wokuvumelanisa wokuvumelanisa, ukusebenza kokuqapha uhlelo, kanye namajeneretha ewashi e-DCM (Isiphathi Sewashi Ledijithali) kanye ne-PLL (Isigaba Esikhiyiwe Loop), kanye nezinketho zokumisa ezithuthukisiwe.Ezinye izici ezisekelwe ku-platform zifaka imojula ye-serial transceiver eyenziwe ngamandla ngamandla ukuze kuthuthukiswe ukuxhumana kwe-serial, imojula ehlanganisiwe ye-PCI Express-compatible endpoint, i-tri-state Ethernet MAC (isilawuli sokufinyelela kwemidiya), kanye ne-PowerPC 440 microprocessor esebenza kahle kakhulu. imojuli eshumekiwe eyenza abaklami bengqondo ethuthukile bakwazi ukuhlanganisa amazinga aphezulu okusebenza ezinhlelweni zabo ezisekelwe ku-FPGA.

Umndeni we-Virtex-6 unikeza izici zakamuva, ezithuthuke kakhulu emakethe ye-FPGA.I-Virtex-6 FPGAs isisekelo sobuchwepheshe be-silicon ehlelekayo semishini yokuhlola okuqondiwe ehlinzeka ngezingxenyekazi zekhompuyutha nezingxenye zesofthiwe ukusiza abaklami bagxile entweni emisha lapho imizamo yokuthuthukisa isiqalile.Umndeni wakwa-Virtex-6 uhlanganisa i-ASMBL yesizukulwane sesithathu (imoduli yephothifoliyo ye-silicon ethuthukisiwe) yezakhiwo zezinsika ezihlanganisa imindeni embalwa ehlukene.Lokhu kubuka konke kuchaza amadivayisi kumindeni engaphansi ye-LXT, SXT, ne-HXT.Umndeni ngamunye ongaphansi uqukethe inhlanganisela ehlukile yezici ukuze uhlangabezane ngempumelelo nenani elibanzi lezidingo zomklamo onengqondo.Ngaphezu kwendwangu enengqondo esebenza kahle kakhulu, ama-Virtex-6 FPGA afaka amamojula amaningana akhelwe ngaphakathi wezinga lesistimu.Lezi zici zivumela abaklami abanengqondo ukuthi bakhe amazinga aphezulu okusebenza nokusebenza ezinhlelweni zabo ze-FPGA.I-Virtex-6 FPGAs futhi ihlinzeka ngesixazululo esingcono kakhulu sokuhlangabezana nezidingo zabaklami be-logic abasebenza kahle kakhulu, abaklami be-DSP abasebenza kahle kakhulu, nabaklami besistimu abashumekiwe abasebenza kahle kakhulu, okuletha ingqondo engakaze ibonwe ngaphambili, i-DSP, ukuxhumana, namandla e-microprocessor athambile.

I-Virtex-7 ingumkhiqizo we-FPGA osezingeni eliphezulu kakhulu owethulwe ngo-2011 ngenqubo engu-28nm enikeza amakhasimende inkululeko yokudonsa nokuqaqa izici ezehlisa izindleko namandla asetshenziswayo kuyilapho kukhulisa ukusebenza namandla, ngaleyo ndlela kunciphisa ukuthuthukiswa nokutshalwa kwezimali kokuphakelwa kokubili okuphansi. -Izindleko kanye nemindeni esebenza kahle kakhulu.Ngaphezu kwalokho, ukuncishiswa kwezindleko okungama-35% uma kuqhathaniswa ne-Virtex-6 kuqinisekiswa ngaphandle kokuguqulwa okukhulayo noma ukutshalwa kwezimali kobunjiniyela, okwandisa umkhiqizo.
