LCMXO2-256HC-4TG100C Yoyambirira komanso Yatsopano Yokhala Ndi Mtengo Wapikisano Mu Stock IC Supplier

Ngakhale onse awiriFPGAndiCPLDndi zida za ASIC zosinthika ndipo zimakhala ndi mawonekedwe ambiri, chifukwa cha kusiyana kwa kapangidwe ka CPLD ndi FPGA, ali ndi mawonekedwe awo:

1.CPLD ndiyoyenera kwambiri kumaliza ma algorithms osiyanasiyana ndi malingaliro ophatikizika, ndipo FP GA ndiyoyeneranso kukwaniritsa malingaliro otsatizana.Mwanjira ina, FPGA ndiyabwino kwambiri pamapangidwe olemera a flip-flop, pomwe CPLD ndiyabwino kwambiri pa flip-flop limited and product term rich structure.

2.Mapangidwe opitilira njira a CPLD amatsimikizira kuti kuchedwa kwake kwa nthawi kumakhala kofanana komanso kodziwikiratu, pomwe gawo la FPGA la FPGA limatsimikizira kuchedwa kwake.

3.FPGA ili ndi kusinthasintha kwambiri kuposa CPLD pamapulogalamu.CPLD imakonzedwa ndikusintha magwiridwe antchito ndi gawo lolumikizana lamkati, pomwe FPGA imakonzedwa ndikusintha mawaya a kulumikizana kwamkati.FP GA ikhoza kukonzedwa pansi pa chipata cha logic, pamene CPLD imakonzedwa pansi pa logic block.

4.Kuphatikizika kwa FPGA ndikwapamwamba kuposa CPLD, ndipo ili ndi mawonekedwe ovuta kwambiri a wiring ndi kukhazikitsa malingaliro.

5.CPLD ndiyosavuta kugwiritsa ntchito kuposa FPGA.Mapulogalamu a CPLD pogwiritsa ntchito ukadaulo wa E2PROM kapena FASTFLASH, palibe chipangizo chokumbukira chakunja, chosavuta kugwiritsa ntchito.Komabe, zidziwitso zamapulogalamu a FPGA ziyenera kusungidwa mu kukumbukira kwakunja, ndipo njira yogwiritsira ntchito ndiyovuta.

6. CPLDS ndi yachangu kuposa FPgas ndipo ali ndi nthawi yolosera kwambiri.Izi ndichifukwa choti ma FPGas ndi mapulogalamu apazipata ndipo zolumikizana zogawidwa zimatengedwa pakati pa CLBS, pomwe CPLDS ndi mapulogalamu a logic block-level ndipo kulumikizana pakati pa midadada yawo kumasokonekera.

7.Munjira yamapulogalamu, CPLD imakhazikika pa E2PROM kapena FLASH memory programming, nthawi zamapulogalamu mpaka nthawi 10,000, ubwino wake ndikuti makinawo amazimitsa zambiri zamapulogalamu samatayika.CPLD ikhoza kugawidwa m'magulu awiri: mapulogalamu pa mapulogalamu ndi mapulogalamu pa dongosolo.Zambiri za FPGA zimachokera ku mapulogalamu a SRAM, chidziwitso cha mapulogalamu chimatayika pamene dongosolo lazimitsidwa, ndipo deta ya mapulogalamu iyenera kulembedwa ku SRAM kuchokera kunja kwa chipangizo nthawi iliyonse yomwe yayatsidwa.Ubwino wake ndikuti ukhoza kukonzedwa nthawi iliyonse, ndipo ukhoza kukonzedwa mwamsanga mu ntchito, kuti ukwaniritse kasinthidwe kameneka pamagulu a bolodi ndi dongosolo la dongosolo.

8.Chinsinsi cha CPLD ndichabwino,Chinsinsi cha FPGA ndichabwino.

9.Mwachizoloŵezi, mphamvu yogwiritsira ntchito mphamvu ya CPLD ndi yaikulu kuposa ya FPGA, ndipo pamwamba pa digiri ya kuphatikizika, ndizodziwikiratu.
