LCMXO2-256HC-4TG100C Thawj thiab Tshiab Nrog Tus Nqi Sib Tw Hauv Tshuag IC Chaw Muag Khoom

Txawm tias ob leegFPGAthiabCPLDyog cov programmable ASIC thiab muaj ntau yam zoo sib xws, vim qhov sib txawv ntawm cov qauv ntawm CPLD thiab FPGA, lawv muaj lawv tus yam ntxwv:

1.CPLD yog qhov tsim nyog rau kev ua kom tiav ntau yam algorithms thiab combinatorial logic, thiab FP GA yog qhov tsim nyog rau kev ua tiav cov txheej txheem sib luag.Hauv lwm lo lus, FPGA yog qhov tsim nyog rau flip-flop nplua nuj qauv, thaum CPLD zoo dua rau flip-flop txwv thiab cov khoom lag luam cov qauv nplua nuj.

2.Cov qauv routing tsis tu ncua ntawm CPLD txiav txim siab tias nws lub sijhawm ncua sijhawm yog qhov sib xws thiab kwv yees tau, thaum lub sijhawm segmented routing qauv ntawm FPGA txiav txim siab nws ncua sijhawm tsis muaj kev cia siab.

3.FPGA muaj kev hloov pauv ntau dua li CPLD hauv kev ua haujlwm.CPLD yog programmed los ntawm kev hloov cov logic muaj nuj nqi nrog ib tug ruaj khov kev twb kev txuas Circuit Court, thaum FPGA yog programmed los ntawm kev hloov cov xov hlau ntawm lub internal kev twb kev txuas.FP GA tuaj yeem ua haujlwm raws li lub rooj vag logic, thaum CPLD yog programmed nyob rau hauv lub logic block.

4.Qhov kev sib koom ua ke ntawm FPGA yog siab dua li ntawm CPLD, thiab nws muaj ntau txoj hlua txuas thiab kev siv logic.

5.CPLD yooj yim dua rau siv dua li FPGA.CPLD programming siv E2PROM lossis FASTFLASH thev naus laus zis, tsis muaj lub cim xeeb sab nraud, siv tau yooj yim.Txawm li cas los xij, cov ntaub ntawv programming ntawm FPGA yuav tsum tau muab cia rau hauv lub cim xeeb sab nraud, thiab txoj kev siv yog qhov nyuaj.

6. CPLDS sai dua FPgas thiab muaj lub sijhawm kwv yees ntau dua.Qhov no yog vim FPGas yog lub rooj sib tham theem thiab kev sib txuas sib txuas tau txais los ntawm CLBS, thaum CPLDS yog logic block-level programming thiab kev sib txuas ntawm lawv cov logic blocks yog lumped.

7 .Hauv txoj kev programming, CPLD feem ntau yog raws li E2PROM lossis FLASH nco programming, programming lub sij hawm mus txog 10,000 lub sij hawm, qhov zoo dua yog tias lub zog tawm ntawm cov ntaub ntawv programming tsis ploj.CPLD tuaj yeem muab faib ua ob pawg: programming ntawm tus programmer thiab programming ntawm lub kaw lus.Feem ntau ntawm FPGA yog raws li SRAM programming, cov ntaub ntawv programming ploj thaum lub kaw lus raug kaw, thiab cov ntaub ntawv programming yuav tsum tau sau rov qab rau SRAM los ntawm sab nraud lub cuab yeej txhua zaus nws siv.Nws qhov zoo dua yog tias nws tuaj yeem raug programmed txhua lub sijhawm, thiab nws tuaj yeem ua haujlwm sai sai hauv kev ua haujlwm, thiaj li ua tiav kev teeb tsa dynamic ntawm pawg thawj coj thiab theem system.

8.CPLD kev ceev ntiag tug yog qhov zoo, FPGA tsis pub leej twg paub.

9. Feem ntau, kev siv hluav taws xob ntawm CPLD loj dua li ntawm FPGA, thiab qhov siab dua ntawm kev sib koom ua ke, qhov pom tseeb dua.
