LCMXO2-640HC-4TG100C 100% Chatsopano & Choyambirira cha MachXO2 Field Programmable Gate Array (FPGA) IC 78 18432 640 100-LQFP

Zosintha mwamakonda kwambiri SoC.Mwachitsanzo - malo olumikizirana omwe amalumikizidwa ndi cpus zodziwika bwino komanso midadada yosinthika yosinthika.Zotsatira zake, ophatikiza machitidwe amabweretsa mayankho omwe amaphatikiza malire odziwika bwino (zosokoneza zosokoneza).Chifukwa chake zomwe zimabwera m'maganizo apa ndikuyambitsa kwa hardware m'magawo achitetezo, ma network, malo opangira data, ndi zina zambiri.

 Kuphatikiza apo, FPGA itha kugwiritsidwanso ntchito ndi powerpc kapena ARM-based cpus.Chifukwa chake, ndizotheka kupanga mwachangu SoC yomwe idzakhala ndi mawonekedwe osinthika kwambiri kuzunguliraCPUyomwe code yomwe ilipo idapangidwa kale.Mwachitsanzo, makhadi othamangitsa ma hardware ochita malonda othamanga kwambiri.

 Ma FPGA apamwamba amagwiritsidwa ntchito kupeza "zaulere" mawonekedwe apamwamba kwambiri monga PCIe Gen 3, 10/40Gbps Ethernet, SATA Gen 3, DDR3 gobs ndi gobs, kukumbukira kwa QDR4.Nthawi zambiri, kupeza ip iyi ku ASIC ndikokwera mtengo.Koma FPGA imatha kukuyambitsani mwachangu, chifukwa ma cores awa amatha kugwiritsidwa ntchito ngati tchipisi tatsimikiziridwa kale, chifukwa chake zimangotenga kachigawo kakang'ono ka nthawi yachitukuko kuti muphatikize mudongosolo.

 FPGA ili ndi ochulutsa ochepa komanso kukumbukira mkati.Choncho, iwo ali oyenererana ndi machitidwe opangira zizindikiro.Chifukwa chake, muwapeza mu zida zomwe zimapanga ma siginecha ndi multiplexing/demultiplexing.Mwachitsanzo, zida zamagetsi zopanda zingwe, monga masiteshoni oyambira.

 Chinthu chaching'ono kwambiri mu FPGA chimatchedwa logic block.Ichi ndi choyambitsa cha ALU+.Zotsatira zake, FPGA imagwiritsidwa ntchito kwambiri pamavuto apakompyuta omwe angapindule ndi zomanga zamtundu wa SIMD.Zitsanzo zikuphatikizapo kuyeretsa zithunzi zolandiridwa kuchokera ku masensa azithunzi, mfundo kapena kukonza mapikseli azithunzi, monga kuwerengera ma vectors osiyanitsa H.264 compression, etc.

 Potsirizira pake, kuyerekezera kwa ASIC kapena hardware / mapulogalamu mu kuyesa mphete, etc. FPGA logic design imagawana njira ndi zida zomwezo monga ASIC design.Fpgas amagwiritsidwanso ntchito kutsimikizira milandu ina yoyesera panthawi ya chitukuko cha ASIC, kumene kuyanjana pakati pa hardware ndi mapulogalamu kungakhale kovuta kwambiri kapena kuwononga nthawi kuti ayese.
