LCMXO2-256HC-4TG100C Umwimerere na Gishya hamwe nigiciro cyo guhatanira isoko ryimigabane IC

Nubwo byombiFPGAnaCPLDni porogaramu zishobora gukoreshwa ASIC kandi zifite ibintu byinshi bihuriweho, kubera itandukaniro ryimiterere ya CPLD na FPGA, bafite ibiranga:

1.CPLD irakwiriye cyane kurangiza algorithm zitandukanye hamwe na logique ikomatanya, kandi FP GA irakwiriye kurangiza logique ikurikiranye.Muyandi magambo, FPGA irakwiriye cyane kuri flip-flop imiterere ikungahaye, mugihe CPLD ikwiranye na flip-flop igarukira hamwe nibicuruzwa bikoreshwa muburyo bukize.

2.Uburyo bukomeza bwo kuyobora inzira ya CPLD bugena ko gutinda kwigihe cyayo ari kimwe kandi giteganijwe, mugihe ibice byanyuze mubice bya FPGA bigena gutinda kwayo.

3.FPGA ifite guhinduka kurenza CPLD muri gahunda.CPLD yateguwe muguhindura imikorere ya logique hamwe nu murongo wimbere wimbere, mugihe FPGA yateguwe muguhindura insinga zimbere.FP GA irashobora gutegurwa munsi y irembo ryumvikana, mugihe CPLD yateguwe munsi yumutwe.

4.Ihuriro rya FPGA rirenze irya CPLD, kandi rifite imiterere igoye yo gukoresha no gushyira mubikorwa logique.

5.CPLD iroroshye gukoresha kuruta FPGA.Porogaramu ya CPLD ukoresheje E2PROM cyangwa tekinoroji ya FASTFLASH, nta chip yo kwibuka yo hanze, byoroshye gukoresha.Ariko, amakuru yo gutangiza amakuru ya FPGA agomba kubikwa mububiko bwo hanze, kandi uburyo bwo gukoresha buragoye.

6. CPLDS yihuta kurusha FPgas kandi ifite igihe kinini cyo guhanura.Ibi ni ukubera ko FPGas ari amarembo yo murwego rwohejuru kandi ikwirakwizwa ryemewe ryemewe hagati ya CLBS, mugihe CPLDS ari logique yo murwego rwohejuru kandi gahunda ihuza imiyoboro yabo ihuriweho.

7．Mu buryo bwo gutangiza gahunda, CPLD ishingiye cyane cyane kuri E2PROM cyangwa FLASH yibuka ya progaramu yo kwibuka, inshuro zo gutangiza inshuro zigera ku 10,000, akarusho nuko sisitemu imbaraga zitanga amakuru yo gutangiza amakuru zitabura.CPLD irashobora kugabanywamo ibyiciro bibiri: gahunda kuri programmer na programming kuri sisitemu.Byinshi muri FPGA bishingiye kuri progaramu ya SRAM, amakuru yo gutangiza amakuru abura iyo sisitemu ikuweho, kandi amakuru yo gutangiza amakuru agomba kwandikwa asubira muri SRAM avuye hanze yicyuma igihe cyose akozwe.Akarusho kayo nuko ishobora gutegurwa igihe icyo aricyo cyose, kandi irashobora gutegurwa vuba mumurimo, kugirango igere kumurongo wimikorere kurwego rwubuyobozi no kurwego rwa sisitemu.

8．CPLD ibanga ni ryiza, ibanga rya FPGA ni ribi.

9.Muri rusange, gukoresha ingufu za CPLD ni binini kuruta ibya FPGA, kandi urwego rwo hejuru rwo kwishyira hamwe, biragaragara.
