XC7K420T-2FFG901I – Integrated Circuits, Embedded, Field Programmable Gate Arrays

Qhov zoo
Qhov zoo ntawm FPGAs yog raws li nram no:
(1) FPGAs muaj cov khoom siv kho vajtse xws li logic cells, RAM, multipliers, thiab lwm yam. Los ntawm kev teeb tsa cov khoom siv kho vajtse rationally, hardware circuits xws li multipliers, registers, address generators, etc.
(2) FPGAs tuaj yeem tsim los ntawm kev siv daim duab thaiv lossis Verilog HDL, los ntawm cov rooj vag yooj yim mus rau FIR lossis FFT circuits.
(3) FPGAs tuaj yeem ua tiav tsis tu ncua reprogrammed, thauj cov qauv tsim tshiab hauv ob peb puas milliseconds, siv kev teeb tsa los txo cov khoom siv hluav taws xob.
(4) Kev khiav hauj lwm zaus ntawm FPGA yog txiav txim siab los ntawm FPGA nti nrog rau cov qauv tsim, thiab tuaj yeem hloov kho lossis hloov nrog lub nti nrawm dua kom tau raws li qee qhov xav tau (txawm hais tias, tau kawg, kev ua haujlwm zaus tsis txwv thiab tuaj yeem ua tau. tau nce, tab sis yog tswj hwm los ntawm cov txheej txheem IC tam sim no thiab lwm yam).
Qhov tsis zoo
Qhov tsis zoo ntawm FPGAs yog raws li hauv qab no:
(1) FPGAs cia siab rau kev siv kho vajtse rau txhua qhov haujlwm thiab tsis tuaj yeem siv cov haujlwm xws li kev sib tw ua haujlwm.
(2) FPGAs tsuas tuaj yeem siv cov haujlwm ruaj khov.
Hauv cov ntsiab lus: FPGAs cia siab rau kho vajtse los siv tag nrho cov haujlwm thiab tuaj yeem muab piv rau cov chips tshwj xeeb hauv cov ntsiab lus ntawm kev ceev, tab sis muaj qhov sib txawv loj hauv kev tsim qauv piv rau cov txheej txheem dav dav.

Tsim hom lus thiab platforms

Programmable logic li yog cov khoom siv kho vajtse uas ua kom pom tseeb cov haujlwm tsim thiab cov kev qhia tshwj xeeb ntawm kev siv hluav taws xob los ntawm EDA thev naus laus zis.FPGAs, raws li ib qho ntawm cov khoom siv tseem ceeb uas siv txoj hauv kev no, yog cov neeg siv ncaj qha, hloov tau yooj yim thiab ntau yam, siv tau yooj yim, thiab nrawm rau kev sim thiab siv hauv cov khoom siv.
Hardware Description Language (HDL) yog ib hom lus siv los tsim digital logic systems thiab piav qhia txog digital circuits, cov ntsiab lus tseem ceeb uas siv yog VHDL, Verilog HDL, System Verilog thiab System C.
Raws li cov lus piav qhia ntawm txhua yam khoom siv kho vajtse, Cov Lus Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij (VHDL) muaj cov yam ntxwv ntawm kev ywj pheej ntawm cov khoom siv tshwj xeeb hauv Circuit Court thiab ywj pheej ntawm lub platform tsim, nrog rau qhov zoo ntawm kev piav qhia dav dav, tsis yog. nyob ntawm cov khoom siv tshwj xeeb, thiab muaj peev xwm piav qhia txog kev tsim cov txheej txheem tswj kev nyuaj hauv txoj cai nruj thiab nruj, thiab lwm yam. Nws tau txais kev txhawb nqa los ntawm ntau lub tuam txhab EDA thiab tau siv dav hauv kev tsim hluav taws xob.dav siv.
VHDL yog ib hom lus siab rau kev tsim hluav taws xob, thiab piv nrog lwm yam lus piav qhia kho vajtse, nws muaj cov yam ntxwv ntawm cov lus yooj yim, yooj yim thiab kev ywj pheej los ntawm kev tsim khoom, ua rau nws yog ib hom lus piav qhia kho vajtse rau EDA thev naus laus zis thiab ua EDA thev naus laus zis ntau dua. siv tau rau cov neeg tsim qauv.
Verilog HDL yog cov lus piav qhia kho vajtse dav siv uas tuaj yeem siv ntau theem ntawm cov txheej txheem tsim kho vajtse, suav nrog kev ua qauv, kev sib txuas thiab simulation.
Verilog HDL Qhov Zoo: zoo ib yam li C, yooj yim kawm thiab hloov tau.Case-sensitive.Qhov zoo ntawm kev sau ntawv stimulus thiab qauv.Qhov tsis zoo: ntau qhov yuam kev tsis tuaj yeem tshawb pom thaum lub sijhawm sau.
VHDL Pros: Rigorous syntax, meej hierarchy.Disadvantages: ntev lub sij hawm paub, tsis saj zawg zog txaus.
Quartus_II software yog qhov ua tiav ntau lub platform tsim ib puag ncig tsim los ntawm Altera, uas tuaj yeem ua tau raws li cov kev xav tau ntawm ntau yam FPGAs thiab CPLDs, thiab yog ib puag ncig zoo rau kev tsim cov txheej txheem ntawm chip programmable.
Vivado Design Suite, ib puag ncig tsim kev sib koom ua ke tso tawm los ntawm FPGA tus neeg muag khoom Xilinx hauv 2012. Nws suav nrog ib puag ncig tsim kev sib koom ua ke thiab ib tiam tshiab ntawm cov cuab yeej los ntawm qhov system mus rau qib IC, tag nrho tsim los ntawm cov qauv sib faib cov ntaub ntawv thiab ib puag ncig debug.Xilinx Vivado Design Suite muab FIFO IP cores uas tuaj yeem siv tau yooj yim rau kev tsim qauv.
