Makhalidwe a Zamalonda

A. Kodi tchipisi ta FPGA ndi chiyani

Pakadali pano, tchipisi ta FPGA pamsika makamaka zimachokera ku Xilinx ndi Altera, zomwe zimakhala zoposa 80% ya msika wa FPGA.Zogulitsa zina za opanga ma FPGA ndizogwiritsa ntchito zina, mwachitsanzo, Actel makamaka imapanga ma FPGAs odana ndi fuse kuti akwaniritse zofunikira kwambiri pakugwiritsira ntchito zinthu zakuthambo ndi zamlengalenga.Zotsatirazi ndi zoimira makampani awiri, Altera ndi Xilinx.

Zogulitsa za Altera

Zipangizo za Altera za FPGA zagawidwa pafupifupi magawo atatu: imodzi ndi mndandanda wa Cyclone wotsika;yachiwiri ndi mndandanda wapamwamba wa Stratix, ndipo chachitatu ndi mndandanda wa Arriva womwe ukhoza kukhala ASICized mosavuta pakati pa awiriwo.

1. kwa ma FPGA ochita bwino kwambiri a Stratix

Ma FPGA a Stratix atha kuthandiza ogwiritsa ntchito kuchepetsa chiwopsezo komanso magwiridwe antchito apamwamba posachedwa kuti ayambitse zinthu zapamwamba kwambiri.Kuphatikiza kachulukidwe kwambiri, magwiridwe antchito apamwamba, komanso mawonekedwe olemera, banja la Stratix la FPGAs limatha kuphatikiza zinthu zambiri ndikuwonjezera bandwidth yadongosolo.Mawonekedwe a banja la Stratix la mibadwo yazogulitsa ndikusintha ndipo akupitiliza kusinthika.Madeti oyambitsa ndi matekinoloje amtundu wa Stratix banja la FPGA akuwonetsedwa mu Gulu 1-1.

Table 1-1 Stratix Series Table

Mitundu ya Stratix FPGAs ndi Stratix GX ndiye zitsanzo zoyambirira kwambiri m'banja la Altera's Stratix FPGA.Banja ili la ma FPGA ochita bwino kwambiri limayambitsa ma module a DSP hardcore intellectual property (IP) ndi ma Altera omwe amagwiritsidwa ntchito kwambiri pa TriMatrix pa-chip memory komanso ma I/O osinthika.

Mitundu ya Stratix II FPGA ndi Stratix II GX imayambitsa zomanga za Adaptive Logic Module (ALM), zomwe zimalowa m'malo mwa 4-input LUT ndi tebulo lapamwamba la 8-input segmented segment (LUT).II GX FPGAs ndipo amalimbikitsidwabe kuti apange mapangidwe atsopano.

Stratix III FPGAs ndi makampani otsika kwambiri, ochita bwino kwambiri 65nm FPGAs.atha kutenga mwayi wamtundu wa logic (L), kukumbukira, ndi kukulitsa kwa DSP (E) kuphatikiza zofunikira za kapangidwe ka wogwiritsa ntchito popanda kupanga ndi zinthu zokulirapo kuposa zomwe zimafunikira, potero kusunga ma board, kufupikitsa nthawi yophatikiza, ndi kuchepetsa ndalama.Strategic III FPGAs adapangidwa kuti azikonza makina apamwamba kwambiri pamapulogalamu ambiri.

Stratix IV FPGAs amapereka kachulukidwe kwambiri, magwiridwe antchito abwino kwambiri, komanso kugwiritsa ntchito mphamvu pang'ono pa 40nm FPGA iliyonse.Banja la Stratix IV FPGA limapereka zida zowonjezera (E) ndi zida zowonjezera zokhala ndi ma transceivers (GX ndi GT) kuti akwaniritse zosowa zamisika yambiri ndi mapulogalamu monga kulumikizana opanda zingwe ndi mizere yokhazikika, asitikali, kuwulutsa, ndi zina zambiri, 40nm FPGA yapamwamba iyi. banja limaphatikizapo ma transceivers apamwamba kwambiri a 11.3 Gbps.

Ma Stratix V FPGA amakwaniritsa ma bandwidth apamwamba kwambiri komanso kuphatikiza kwadongosolo kwamtundu uliwonse wa 28nm FPGA ndipo ndi osinthika kwambiri.Banja la chipangizocho limaphatikizapo mitundu ya 14.1 Gbps (GS ndi GX) yokhala ndi ndege yobwerera kumbuyo, chip-to-chip, ndi chip-to-module, komanso ma transceiver a 28G (GT) omwe amathandiza chip-to-chip ndi chip-to- module yokhala ndi ma LE opitilira miliyoni imodzi ndi ma module a DSP 4,096 olondola.

Altera Stratix 10 FPGAs yokhala ndi ukadaulo wa Intel's 14nm wokhala ndi zipata zitatu imapereka magwiridwe antchito abwino kwambiri, bandwidth, ndi kuphatikiza kachitidwe ka FPGA iliyonse, komanso kugwiritsa ntchito mphamvu zochepa kwambiri.Zida za 10 zili ndi ma transceivers a 56Gbps, 28Gbps backplanes, floating-point digital signal processing (DSP) ntchito, ndi chithandizo cha IEEE 754 yowonjezereka. -generation hard-core processor system yokonzedwa kuti igwire bwino ntchito pa watt.
