Izimfanelo Zomkhiqizo

A. Ayini ama-chips e-FPGA ajwayelekile

Njengamanje, ama-FPGA chips emakethe avela ikakhulukazi kwa-Xilinx nase-Altera, athatha ngaphezu kwama-80% wesabelo semakethe se-FPGA.Eminye imikhiqizo yabakhiqizi be-FPGA yenzelwe ikakhulukazi izinhlelo zokusebenza ezithile, isibonelo, i-Actel ikakhulukazi ikhiqiza ama-FPGA esakhiwo esilwa ne-fuse ukuze ihlangabezane nezimo ezidingeka kakhulu zokusetshenziswa kwemikhiqizo yezindiza kanye ne-aerospace.Okulandelayo yimikhiqizo emele izinkampani ezimbili, i-Altera ne-Xilinx.

Imikhiqizo ejwayelekile ye-Altera

Amadivayisi e-Altera's FPGA ahlukaniswe cishe abe uchungechunge oluthathu: olulodwa uchungechunge lwe-Cyclone olusezingeni eliphansi;okwesibili uchungechunge lwe-Stratix olusezingeni eliphezulu, kanti okwesithathu uchungechunge lwe-Arriva olungase lube lula phakathi kwalokhu kokubili.

1. ochungechungeni lwe-Stratix olusebenza kahle kakhulu lwama-FPGA

Ama-FPGA ochungechunge lwe-Stratix angasiza abasebenzisi behlise ubungozi nokusebenza okuphezulu ngokushesha okukhulu ukuze baqalise imikhiqizo esezingeni eliphezulu kakhulu.Ukuhlanganisa ukuminyana okuphezulu, ukusebenza okuphezulu, nezici ezinothile, umndeni wakwa-Stratix wama-FPGA ungahlanganisa izici eziningi futhi ukhulise umkhawulokudonsa wesistimu.Izici zomndeni wakwa-Stratix wezizukulwane zomkhiqizo ziyaguquguquka futhi ziyaqhubeka nokuvela.Izinsuku zokwethulwa kanye nobuchwepheshe benqubo yomndeni wakwa-Stratix we-FPGAs kukhonjisiwe kuThebula 1-1.

Ithebula 1-1 Ithebula le-Stratix Series

Amamodeli e-Stratix FPGA kanye ne-Stratix GX angamamodeli okuqala emndenini wakwa-Altera's Stratix FPGA.Lo mndeni wama-FPGA asebenza kahle kakhulu wethula amamojula e-DSP hardcore property intellectual property (IP) kanye nenkumbulo esetshenziswa kakhulu ye-TriMatrix on-chip ye-Altera kanye nezakhiwo eziguquguqukayo ze-I/O.

Amamodeli e-Stratix II FPGA kanye ne-Stratix II GX ethula ukwakheka kwe-Adaptive Logic Module (ALM), ethatha indawo ye-LUT yokokufaka okungu-4 ngethebula lokubheka elihlukaniswe izingxenye ezingu-8 (LUT) elisebenza kahle kakhulu elingu-8-input.II GX FPGAs futhi asanconywa kakhulu ngemiklamo emisha.

Ama-FPGA e-Stratix III angamandla aphansi embonini, ama-FPGA asebenza kakhulu angama-65nm.ingathatha ithuba lohlobo lokucabanga (L), inkumbulo, kanye nokuthuthukiswa kwe-DSP (E) ukuze kuhlanganiswe izimfuneko zensiza yokuklama yomsebenzisi ngaphandle kokuklama ngezisetshenziswa ezinkulu kakhulu kunalokho okudingekayo, ngaleyo ndlela ilondoloze amabhodi, ifinyeze isikhathi sokuhlanganisa, nokunciphisa izindleko.strategic III FPGAs ngokuyinhloko yakhelwe ukucubungula okusezingeni eliphezulu core uhlelo lokusebenza eziningi.

Ama-Stratix IV FPGA anikezela ngokuminyana okuphezulu kakhulu, ukusebenza kahle kakhulu, kanye nokusetshenziswa kwamandla okuphansi kunawo wonke ama-40nm FPGA.Umndeni wakwa-Stratix IV FPGA uhlinzeka ngamadivayisi athuthukisiwe (E) nathuthukisiwe anama-transceivers (GX kanye ne-GT) ukuze ahlangabezane nezidingo zezimakethe eziningi nezinhlelo zokusebenza ezifana nokuxhumana okungenantambo nokuxhumana okungaguquki, ezempi, ukusakaza, nokuningi, le 40nm FPGA esebenza kahle kakhulu. umndeni uhlanganisa ama-transceivers e-11.3 Gbps asezingeni eliphezulu kakhulu.

Ama-Stratix V FPGA afinyelela umkhawulokudonsa ophezulu kakhulu nokuhlanganiswa kwesistimu okuphezulu kakhulu kwanoma iyiphi i-28nm FPGA futhi avumelana nezimo ngokwedlulele.Umndeni wedivayisi uhlanganisa amamodeli angu-14.1 Gbps (GS ne-GX) anendiza yasemuva ehambisanayo, i-chip-to-chip, nokusebenza kwe-chip-to-module, kanye namamodeli e-transceiver angu-28G (GT) asekela i-chip-to-chip ne-chip-to- imojula enama-LE angaphezu kwesigidi kanye namamojula e-DSP anembile angu-4,096.

I-Altera Stratix 10 FPGAs enobuchwepheshe be-Intel be-14nm enamasango amathathu anikeza ukusebenza okuhle kakhulu, umkhawulokudonsa, nokuhlanganiswa kwesistimu kwanoma iyiphi i-FPGA, kanye nokusetshenziswa kwamandla okuphansi kakhulu.Amadivayisi abalulekile ayi-10 afaka ama-transceiver angu-56Gbps, izindiza ezingemuva ezingu-28Gbps, ukusebenza kwe-floating-point digital signal processing (DSP) kanye nokusekelwa kwe-IEEE 754 ethuthukisiwe. -Isistimu ye-hard-core processor elungiselelwe ukusebenza kahle nge-watt ngayinye.
