Kapangidwe Kapangidwe ka Bolodi ka FPGA PCB Yowonjezera
  • Kupititsa patsogolo FPGA PCB Board Design

Kufotokozera Kwachidule:

FPGA pcb board.iCore4 dual-core industrial control board ndi gulu lachinayi la iCore mndandanda wapawiri-core board yomwe idakhazikitsidwa ndi kampaniyo;chifukwa cha mawonekedwe ake apadera a ARM + FPGA "ofanana ndi amodzi" amitundu iwiri, imatha kugwiritsidwa ntchito poyesa mayeso ambiri ndi magawo owongolera.ICore4 ikagwiritsidwa ntchito pachimake chazogulitsa, "ARM" pachimake imakhala ngati gawo la CPU (itha kunenedwanso kuti ndi gawo la "serial" lakupha), lomwe limayang'anira kukhazikitsa ntchito, kukonza zochitika, ndi mawonekedwe.Monga gawo la "logic device" (kapena "parallel" execution role), "FPGA" core imayang'anira ntchito zofananira, kukonza nthawi yeniyeni, ndi kasamalidwe ka malingaliro.Ma cores awiri "ARM" ndi "FPGA" amalumikizana pogwiritsa ntchito mabasi 16-bit ofanana.Kuthamanga kwapamwamba komanso kosavuta kugwiritsa ntchito mabasi ofananirako kumatsimikizira kukhala kosavuta komanso nthawi yeniyeni ya kusinthana kwa deta pakati pa zingwe ziwiri, zomwe zimapangitsa kuti zingwe ziwirizo "zikhoteke mu chingwe chimodzi" kuti zigwirizane ndi kuwonjezeka kwa ntchito zoyesa ndi kuyeza komanso zodziwikiratu. zinthu zowongolera, Zofunikira pakuchita.

2 Zothandizira

2.1 Makhalidwe Amphamvu:

[1] Pezani USB_OTG, USB_UART ndi EXT_IN njira zitatu zoperekera magetsi;

[2] Mphamvu zamagetsi zamagetsi: Kutulutsa kwamagetsi a digito ndi 3.3V, ndipo dera lapamwamba la BUCK limagwiritsidwa ntchito popereka mphamvu kwa ARM / FPGA / SDRAM, etc.;

[3] FPGA core imayendetsedwa ndi 1.2V, komanso imagwiritsa ntchito dera lapamwamba la BUCK;

[4] FPGA PLL ili ndi maulendo ambiri a analogi, pofuna kuonetsetsa kuti PLL ikugwira ntchito, timagwiritsa ntchito LDO kuti tipereke mphamvu ya analogi ya PLL;

[5] STM32F767IG imapereka chidziwitso chodziyimira pawokha cha analogi kuti chipereke mphamvu yamagetsi pa-chip ADC / DAC;

[6] Amapereka kuyang'anira mphamvu ndi zizindikiro;

2.2 mawonekedwe a ARM:

[1] Kuchita bwino kwambiri STM32F767IG ndi ma frequency akuluakulu a 216M;

[2] 14 kuwonjezereka kwapamwamba kwa I / O;

[3] Multiplexing ndi I / O, kuphatikizapo ARM yomangidwa mu SPI / I2C / UART / TIMER / ADC ndi ntchito zina;

[4] Kuphatikizira 100M Ethernet, mawonekedwe othamanga kwambiri a USB-OTG ndi USB kupita ku UART ntchito yochotsa zolakwika;

[5] Kuphatikizapo 32M SDRAM, mawonekedwe a TF khadi, mawonekedwe a USB-OTG (akhoza kulumikizidwa ku U disk);

[6] 6P FPC debugging mawonekedwe, muyezo adaputala kuti agwirizane ndi ambiri 20p mawonekedwe;

[7] Kugwiritsa ntchito 16-bit parallel bus kuyankhulana;

2.3 Mawonekedwe a FPGA:

[1] Mndandanda wa Altera wa m'badwo wachinayi wa Cyclone FPGA EP4CE15F23C8N amagwiritsidwa ntchito;

[2] Kufikira ku 230 kuwonjezereka kwapamwamba kwa I / O;

[3] FPGA imakulitsa SRAM yapawiri-chip ndi mphamvu ya 512KB;

[4] Kukonzekera kosinthika: kuthandizira JTAG, AS, PS mode;

[5] Kuthandizira kutsitsa FPGA kudzera mu kasinthidwe ka ARM;AS PS ntchito iyenera kusankhidwa kudzera mu jumpers;

[6] Kugwiritsa ntchito 16-bit parallel bus kuyankhulana;

[7] FPGA debug port: FPGA JTAG port;

2.4 Zina:

[1] USB ya iCore4 ili ndi njira zitatu zogwirira ntchito: DEVICE mode, HOST mode ndi OTG mode;

[2] Mtundu wa mawonekedwe a Ethernet ndi 100M full duplex;

[3] Njira yoperekera mphamvu imatha kusankhidwa ndi jumper, mawonekedwe a USB amayendetsedwa mwachindunji, kapena kudzera pamutu wa pini (5V magetsi);

[4] Mabatani awiri odziyimira pawokha amawongoleredwa ndi ARM ndi FPGA motsatana;

[5] Magetsi awiri a LED a iCore4 heterogeneous dual-core industrial control board ali ndi mitundu itatu: yofiira, yobiriwira ndi yabuluu, yomwe imayendetsedwa ndi ARM ndi FPGA motsatira;

[6] Adopt 32.768K passive crystal kuti apereke RTC yeniyeni nthawi wotchi ya dongosolo;
