I-LCMXO2-256HC-4TG100C Yangempela futhi Entsha Ngenani Elincintisanayo Kumhlinzeki we-IC Wesitokwe

Nakuba kokubiliI-FPGAfuthiI-CPLDzingamadivayisi e-ASIC ahlelekayo futhi anezici eziningi ezijwayelekile, ngenxa yomehluko wesakhiwo se-CPLD ne-FPGA, anezici zawo siqu:

I-1.CPLD ifaneleka kakhulu ukuqedela ama-algorithms ahlukahlukene kanye nengqondo ehlangene, futhi i-FP GA ifaneleka kakhulu ukuqedela ukulandelana kokulandelana kwengqondo.Ngamanye amazwi, i-FPGA ifaneleka kakhulu kusakhiwo esicebile se-flip-flop, kuyilapho i-CPLD ifaneleka kakhulu i-flip-flop enomkhawulo kanye nesakhiwo esicebile sethemu lomkhiqizo.

2.Isakhiwo somzila esiqhubekayo se-CPLD sinquma ukuthi ukubambezeleka kwayo kwesikhathi kufana futhi kuyabikezelwa, kuyilapho ukwakheka komzila okuyingxenye ye-FPGA kunquma ukubambezeleka kwayo okungalindelekile.

3.FPGA inokuvumelana nezimo kakhulu kune-CPLD ezinhlelweni.I-CPLD ihlelwe ngokushintsha umsebenzi we-logic ngesekethe yokuxhumana yangaphakathi engaguquki, kuyilapho i-FPGA ihlelwa ngokushintsha izintambo zokuxhuma kwangaphakathi.I-FP GA ingahlelwa ngaphansi kwesango elinengqondo, kuyilapho i-CPLD ihlelwe ngaphansi kwebhulokhi enengqondo.

4.Ukuhlanganiswa kwe-FPGA kungaphezulu kwalokho kwe-CPLD, futhi kunokwakheka kwezintambo eziyinkimbinkimbi kanye nokusetshenziswa okunengqondo.

I-5.CPLD isebenziseka kalula kune-FPGA.Izinhlelo ze-CPLD zisebenzisa ubuchwepheshe be-E2PROM noma i-FASTFLASH, ayikho imemori ye-chip yangaphandle, kulula ukuyisebenzisa.Kodwa-ke, imininingwane yokuhlela ye-FPGA idinga ukugcinwa kumemori yangaphandle, futhi indlela yokusebenzisa iyinkimbinkimbi.

6. I-CPLDS iyashesha kune-FPgas futhi inokubikezelwa okukhulu kwesikhathi.Lokhu kungenxa yokuthi ama-FPGas awuhlelo lwezinga lesango futhi ukuxhumana okusabalalisiwe kwamukelwa phakathi kwe-CLBS, kuyilapho ama-CPLDS ewuhlelo lweleveli yebhulokhi enengqondo futhi ukuxhumana phakathi kwamabhulokhi awo okunengqondo kunezigaxa.

7.Ngendlela yokuhlela, i-CPLD isekelwe ngokuyinhloko ku-E2PROM noma kuhlelo lwenkumbulo ye-FLASH, izikhathi zokuhlela kufika izikhathi ezingu-10,000, inzuzo ukuthi isistimu ivala ulwazi lohlelo alulahleki.I-CPLD ingahlukaniswa ngezigaba ezimbili: ukuhlela kumklami kanye nokuhlela ohlelweni.Iningi le-FPGA lisekelwe ohlelweni lwe-SRAM, ulwazi lohlelo luyalahleka uma isistimu ivaliwe, futhi idatha yokuhlela idinga ukubhalwa ibuyiselwe ku-SRAM ngaphandle kwedivayisi isikhathi ngasinye lapho ivuliwe.Inzuzo yayo ukuthi ingahlelwa nganoma yisiphi isikhathi, futhi ingahlelwa ngokushesha emsebenzini, ukuze kuzuzwe ukucushwa okuguquguqukayo ezingeni lebhodi kanye nezinga lesistimu.

8. Ukugcinwa kuyimfihlo kwe-CPLD kuhle, ukugcinwa kuyimfihlo kwe-FPGA akulungile.

I-9.Ngokujwayelekile, ukusetshenziswa kwamandla kwe-CPLD kukhulu kunaleyo ye-FPGA, futhi ukuphakama kwezinga lokuhlanganisa, kusobala kakhulu.
