Iimpawu zeMveliso

A. Zeziphi iitshiphusi zeFPGA eziqhelekileyo

Okwangoku, iitshiphusi zeFPGA kwimarike ikakhulu zivela kwiXilinx naseAltera, ezithatha ngaphezulu kwe-80% yesabelo semakethi yeFPGA.Iimveliso zabanye abavelisi be-FPGA ubukhulu becala zezezicelo ezithile ezithile, umzekelo, i-Actel ikakhulu ivelisa ubume bokuchasana ne-fuse FPGAs ukuhlangabezana nemiqathango yosetyenziso olubango olugqithisileyo lophapho kunye neemveliso ze-aerospace.Ezi zilandelayo ziyimveliso emele iinkampani ezimbini, i-Altera kunye ne-Xilinx.

Iimveliso eziqhelekileyo ze-Altera

Izixhobo ze-FPGA ze-Altera zahlulwe ngokungqongqo zibe ziichungechunge ezintathu: enye luchungechunge lwe-Cyclone ephantsi;okwesibini luluhlu oluphezulu lwe-Stratix, kwaye okwesithathu luchungechunge lwe-Arriva olunokuthi lube lula kwi-ASICized phakathi kwezi zibini.

1. ukwenzela ukusebenza okuphezulu kwe-Stratix series FPGAs

Ii-FPGA zeStratix zinokunceda abasebenzisi ukuba banciphise umngcipheko kunye nokusebenza okuphezulu ngokukhawuleza ukuba baqalise ezona mveliso ziphezulu zisebenza kakhulu.Ukudibanisa ukuxinana okuphezulu, ukusebenza okuphezulu, kunye neempawu ezityebileyo, usapho lwe-Stratix lwe-FPGA lunokudibanisa amanqaku amaninzi kunye nokunyusa i-bandwidth yenkqubo.Iimpawu zentsapho ye-Stratix yezizukulwana zemveliso ziyinguqu kwaye ziyaqhubeka zivela.Imihla yokuqaliswa kunye nobuchwepheshe benkqubo ye-Stratix yosapho lwe-FPGAs iboniswe kwiThebhile 1-1.

Itheyibhile 1-1 Stratix Series Table

Iimodeli ze-Stratix FPGAs kunye ne-Stratix GX zezona modeli ziphambili kusapho lwe-Altera's Stratix FPGA.Olu sapho lwe-FPGAs olusebenza kakhulu luzisa iimodyuli ze-DSP eziqinileyo zepropathi yengqondo (IP) kunye ne-Altera esetyenziswa ngokubanzi kwimemori ye-TriMatrix kwi-chip kunye ne-I/O eguquguqukayo ye-architecture.

Imodeli ye-Stratix II FPGA kunye ne-Stratix II GX yazisa i-Adaptive Logic Module (ALM) yoyilo lwezakhiwo, ethatha indawo ye-LUT ye-4-input kunye ne-high-performance 8-input segmented segmented table (LUT).II GX FPGAs kwaye zisacetyiswa kakhulu kuyilo olutsha.

I-Stratix III FPGAs zezona zinamandla aphantsi kushishino, ukusebenza okuphezulu kwe-65nm FPGAs.inokusebenzisa uhlobo lwengqiqo (L), inkumbulo, kunye nophuculo lwe-DSP (E) ukudibanisa iimfuno zomthombo woyilo lomsebenzisi ngaphandle kokuyila ngezibonelelo ezinkulu kakhulu kunokuba zifunwa, ngaloo ndlela ugcine iibhodi, ukunciphisa ixesha lokuhlanganisa, kunye nokunciphisa iindleko.strategic III FPGAs ngokuyintloko yenzelwe eliphezulu-isiphelo inkqubo engundoqo processing ezininzi izicelo.

I-Stratix IV FPGAs zibonelela ngoxinaniso oluphezulu, ukusebenza kakuhle, kunye nokusetyenziswa kwamandla okuphantsi kwayo nayiphi na i-40nm FPGA.Intsapho ye-Stratix IV ye-FPGA inikezela ngezixhobo eziphuculweyo (E) kunye nezixhobo eziphuculweyo kunye ne-transceivers (GX kunye ne-GT) ukuhlangabezana neemfuno zeemarike ezininzi kunye nezicelo ezifana nonxibelelwano olungenacingo kunye nomgca osisigxina, umkhosi, usasazo, kunye nokunye, le 40nm FPGA ephezulu yokusebenza. usapho lubandakanya ii-transceivers ze-11.3 Gbps ezigqwesileyo.

I-Stratix V FPGAs ifezekisa i-bandwidth ephezulu kunye neyona ndlela iphezulu yokuhlanganiswa kwayo nayiphi na i-28nm FPGA kwaye iguquguquka kakhulu.Usapho lwesixhobo lubandakanya iimodeli ze-14.1 Gbps (GS kunye ne-GX) ezine-backplane ehambelanayo, i-chip-to-chip, kunye nokusebenza kwe-chip-to-module, kunye neemodeli ze-28G (GT) ze-transceiver ezixhasa i-chip-to-chip kunye ne-chip-to- Imodyuli enee-LE ezingaphezu kwesigidi esinye kunye neemodyuli ze-DSP ezichanekileyo ezingama-4,096.

I-Altera Stratix 10 FPGAs ene-Intel's 14nm itekhnoloji yesango elinesithathu ibonelela ngeyona ndlela isebenzayo, i-bandwidth, kunye nokudityaniswa kwenkqubo yayo nayiphi na i-FPGA, kunye nokusetyenziswa kwamandla aphantsi kakhulu.Izixhobo ezili-10 ezicwangcisiweyo zinee-transceivers ezingama-56Gbps, iinqwelomoya ezingama-28Gbps, ukusebenza kophawu lwedijithali (i-DSP) edadayo, kunye nenkxaso yokuphucula i-IEEE 754 I-Stratix 10 SoC lusapho lokuqala oluphezulu lwe-SoC kwitekhnoloji ye-Intel ye-14nm yesango le-triple-gate transistor kunye nelandelayo. -Isizukulwana esiqinileyo senkqubo yeprosesa eyenzelwe ukusebenza kakuhle ngewatt nganye.
