Idizayini Yebhodi Le-FPGA PCB Ethuthukisiwe

Idizayini Ethuthukisiwe Yebhodi Le-FPGA PCB Isithombe Esifakiwe
  • Idizayini Yebhodi Le-FPGA PCB Ethuthukisiwe

Incazelo emfushane:

FPGA pcb ibhodi.Ibhodi ye-iCore4 dual-core industrial control board iyisizukulwane sesine se-iCore series dual-core board eyethulwe yinkampani;ngenxa yesakhiwo sayo esiyingqayizivele se-ARM + FPGA “ubukhulu obubodwa bulingana-bonke” obumbili, ingasetshenziswa ezinkambini eziningi zokulinganisa nokulawula.Uma i-iCore4 isetshenziswa emnyombweni womkhiqizo, indikimba ye-“ARM” isebenza njengendima ye-CPU (ingabuye ishiwo ukuthi iyindima yokwenza “i-serial”), ebhekele ukuqaliswa komsebenzi, ukucutshungulwa komcimbi, nemisebenzi yesixhumi esibonakalayo.Njengendima “yedivayisi enengqondo” (noma indima yokusayinda “ehambisanayo”), umnyombo we-“FPGA” unesibopho semisebenzi efana nokucubungula okufanayo, ukucutshungulwa kwesikhathi sangempela, nokuphathwa kokunengqondo.Ama-cores amabili “ARM” kanye “ne-FPGA” ayaxhumana kusetshenziswa ibhasi elihambisanayo le-16-bit.Umkhawulokudonsa ophezulu kanye nokusebenziseka kalula kwebhasi elihambisanayo kuqinisekisa ukunethezeka kanye nokusebenza kwesikhathi sangempela kokushintshisana kwedatha phakathi kwama-cores amabili, okwenza ama-cores amabili "asonteke abe yintambo eyodwa" ukuze abhekane nemisebenzi ekhulayo yokuhlola nokulinganisa kanye nokuzenzakalela. lawula imikhiqizo, Izidingo zokusebenza.

2 Izimpawu Zensiza

2.1 Izici zamandla:

[1] Sebenzisa i-USB_OTG, USB_UART kanye EXT_IN nezindlela ezintathu zokuphakela amandla;

[2] Ukunikezwa kwamandla edijithali: Ukukhishwa kwamandla kagesi edijithali kungu-3.3V, futhi isekethe ye-BUCK esebenza kahle kakhulu isetshenziselwa ukunikeza amandla e-ARM / FPGA / SDRAM, njll.;

[3] I-FPGA core inikwa amandla yi-1.2V, futhi isebenzisa isekethe ye-BUCK esebenza kahle kakhulu;

[4] I-FPGA PLL iqukethe inani elikhulu lamasekhethi e-analog, ukuze kuqinisekiswe ukusebenza kwe-PLL, sisebenzisa i-LDO ukuze sinikeze amandla e-analog e-PLL;

[5] I-STM32F767IG ihlinzeka ngereferensi ye-analog voltage ezimele ukuze inikeze i-voltage eyireferensi ye-on-chip ADC / DAC;

[6] Ihlinzeka ngokuqapha kwamandla kanye nokulinganisa;

2.2 Izici ze-ARM:

[1] Ukusebenza okuphezulu kwe-STM32F767IG enemvamisa eyinhloko ye-216M;

[2]14 ukunwetshwa kwe-I/O kokusebenza okuphezulu;

[3] Ukuphindaphinda nge-I/O, kufaka phakathi i-ARM eyakhelwe ngaphakathi i-SPI / I2C / UART / TIMER / ADC neminye imisebenzi;

[4] Kubandakanya i-100M Ethernet, isixhumi esibonakalayo se-USB-OTG esinesivinini esikhulu kanye nomsebenzi we-USB kuya ku-UART wokususa iphutha;

[5] Kubandakanya i-32M SDRAM, isixhumi esibonakalayo sekhadi le-TF, isixhumi esibonakalayo se-USB-OTG (singaxhunywa kudiski ye-U);

[6] Isixhumi esibonakalayo sokulungisa iphutha se-6P FPC, i-adaptha evamile ukuze ivumelane ne-interface ye-20p evamile;

[7] Ukusebenzisa ukuxhumana kwebhasi okuyi-16-bit;

2.3 Izici ze-FPGA:

[1] Kusetshenziswa uchungechunge lweSiphepho sesizukulwane sesine se-Altera i-FPGA EP4CE15F23C8N;

[2] Izandiso ezifika ku-230 ze-I/O zokusebenza okuphezulu;

[3] I-FPGA inweba i-dual-chip SRAM enamandla angu-512KB;

[4] Imodi yokumisa: isekela i-JTAG, AS, imodi ye-PS;

[5] Sekela ukulayisha i-FPGA ngokucushwa kwe-ARM;NJENGOBA umsebenzi we-PS udinga ukukhethwa ngokusebenzisa ama-jumpers;

[6] Ukusebenzisa ukuxhumana kwebhasi okuyi-16-bit;

[7] Imbobo yokususa iphutha ye-FPGA: Imbobo ye-FPGA JTAG;

2.4 Ezinye izici:

[1] I-USB ye-iCore4 inezinhlobo ezintathu zokusebenza: Imodi yeDEVICE, imodi ye-HOST nemodi ye-OTG;

[2] Uhlobo lwesixhumi esibonakalayo se-Ethernet yi-100M egcwele i-duplex;

[3] Imodi yokuphakela amandla ingakhethwa nge-jumper, isixhumi esibonakalayo se-USB sinikwa amandla ngokuqondile, noma ngesihloko sephini (ukunikezwa kwamandla ka-5V);

[4] Izinkinobho ezizimele ezimbili zilawulwa yi-ARM ne-FPGA ngokulandelana;

[5] Izibani ezimbili ze-LED ze-iCore4 heterogeneous dual-core dual-core control board zinemibala emithathu: obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka, elawulwa yi-ARM ne-FPGA ngokulandelana;

[6] I-Adopt 32.768K i-passive crystal ukuze unikeze iwashi lesikhathi sangempela se-RTC kusistimu;
