Mawu Oyamba
Kukonzekera kwachipata cha munda, chomwe chimapangidwa kuti chikule bwino pazida zosinthika monga PAL, GAL, CPLD ndi zina zotero.Zimawoneka ngati gawo lachizoloŵezi pamagulu ogwiritsira ntchito-specific integrated circuits (ASICs), zomwe sizimangothetsa zofooka za mabwalo achizolowezi, komanso zimagonjetsa zoperewera za chiwerengero chochepa cha mabwalo apachipata omwe angakonzedwe.
Mfundo Yogwirira Ntchito
FPGA imatengera lingaliro latsopano la logic cell array LCA (Logic Cell Array), yomwe ili ndi magawo atatu: configurable logic module CLB, output input module IOB (Input Output Block) ndi kulumikiza kwamkati (Interconnect).Zofunikira za FPGAs ndi:
1) Pogwiritsa ntchito FPGA kupanga mabwalo a ASIC, ogwiritsa ntchito safunika kupanga tchipisi kuti apeze chip choyenera.
2) FPGA itha kugwiritsidwa ntchito ngati chitsanzo cha oyendetsa mabwalo ena a ASIC osinthidwa makonda kapena makonda.
3) FPGA ili ndi ma flip-flops ambiri ndi ma I/O mkati.
4) FPGA ndi imodzi mwa zipangizo zomwe zimakhala ndi mawonekedwe afupikitsa, mtengo wotsika kwambiri wa chitukuko komanso chiopsezo chochepa kwambiri mu dera la ASIC.
5) FPGA imatenga njira yothamanga kwambiri ya CHMOS, kugwiritsa ntchito mphamvu zochepa, ndipo imatha kugwirizana ndi CMOS ndi TTL.
Titha kunena kuti tchipisi ta FPGA ndi imodzi mwazisankho zabwino kwambiri zamakina ang'onoang'ono kuti apititse patsogolo kuphatikizana kwamakina ndi kudalirika.
FPGA imakonzedwa ndi pulogalamu yosungidwa pa-chip RAM kuti ikhazikitse momwe ikugwirira ntchito, kotero RAM ya pa-chip iyenera kukonzedwa ikamagwira ntchito.Ogwiritsa ntchito amatha kugwiritsa ntchito njira zosiyanasiyana zamapulogalamu molingana ndi mitundu yosiyanasiyana yosinthira.
Mphamvu ikayatsidwa, chipangizo cha FPGA chimawerenga zomwe zachokera ku EPROM kupita ku RAM yopangira pa-chip, ndipo kukonzanso kukamaliza, FPGA imalowa m'malo ogwirira ntchito.Mphamvu itatayika, FPGA imabwerera ku mapepala oyera, ndipo mgwirizano wamkati wamkati umatha, kotero FPGA ikhoza kugwiritsidwa ntchito mobwerezabwereza.Kukonzekera kwa FPGA sikufuna wodzipatulira wa FPGA, EPROM ndi pulogalamu ya PROM yokha.Mukafuna kusintha ntchito ya FPGA, ingosinthani EPROM.Mwanjira iyi, FPGA yomweyo, deta yosiyana siyana, imatha kupanga ntchito zosiyanasiyana zadera.Chifukwa chake, kugwiritsa ntchito ma FPGA ndikosinthika kwambiri.
Zosintha Zosintha
FPGA ili ndi mitundu yosiyanasiyana yosinthira: njira yayikulu yofananira ndi FPGA kuphatikiza EPROM;Mphunzitsi-kapolo amatha kuthandizira pulogalamu imodzi ya PIECE PROM ma FPGA angapo;Mtundu wa seri ukhoza kukonzedwa ndi serial PROM FPGA;Zozungulira mawonekedwe amalola FPGA kugwiritsidwa ntchito ngati chotumphukira cha microprocessor, yokonzedwa ndi microprocessor.
Nkhani monga kutseka nthawi mwachangu, kuchepetsa kugwiritsa ntchito mphamvu ndi mtengo, kukhathamiritsa kasamalidwe ka mawotchi, komanso kuchepetsa zovuta za mapangidwe a FPGA ndi PCB nthawi zonse zakhala nkhani zazikulu kwa akatswiri opanga makina ogwiritsa ntchito ma FPGA.Masiku ano, pamene ma FPGA akupita ku kachulukidwe kake, mphamvu zambiri, kutsika kwa mphamvu, ndi kuphatikizika kwa IP, akatswiri opanga makina amapindula ndi machitidwe apamwambawa pamene akukumana ndi zovuta zapangidwe zatsopano chifukwa cha kuchuluka kwa ntchito ndi kuthekera kwa FPGAs.
