Gutezimbere Ubuyobozi bwa FPGA PCB

Kuzamura FPGA PCB Ubuyobozi Bwashushanyije
  • Gutezimbere Ubuyobozi bwa FPGA PCB

Ibisobanuro bigufi:

Ubuyobozi bwa pPb.iCore4 ibice bibiri-bigenzura inganda ni igisekuru cya kane iCore ikurikirana ibyiciro bibiri-byashyizweho na sosiyete;bitewe na ARM + FPGA idasanzwe "imwe-imwe-ihuza-yose" imiterere-ibiri-yibanze, irashobora gukoreshwa mubipimo byinshi byo gupima no kugenzura.Iyo iCore4 ikoreshwa murwego rwibicuruzwa, intangiriro ya "ARM" ikora nkuruhare rwa CPU (birashobora kandi kuvugwa ko ari "serial" uruhare), ishinzwe gushyira mubikorwa, gutunganya ibyabaye, nibikorwa byimikorere.Nka "igikoresho cya logique" uruhare (cyangwa "parallel" uruhare rwo gusohoza), intangiriro ya "FPGA" ishinzwe imirimo nko gutunganya ibintu kimwe, gutunganya igihe, no gucunga neza.Cores ebyiri "ARM" na "FPGA" zishyikirana ukoresheje bisi ya biti 16.Umuvuduko mwinshi hamwe no koroshya gukoresha bisi ibangikanye byemeza ko byoroha nigihe gikwiye cyo guhanahana amakuru hagati ya cores zombi, bigatuma ibice bibiri "bihinduranya umugozi umwe" kugirango bihangane nibikorwa byiyongera byo gupima no gupima no kwikora kugenzura ibicuruzwa, Ibisabwa.

2 Ibiranga Ibikoresho

2.1 Ibiranga imbaraga:

[1] Emera USB_OTG, USB_UART na EXT_IN uburyo butatu bwo gutanga amashanyarazi;

[2] Amashanyarazi ya digitale: Ibisohoka mumashanyarazi ya digitale ni 3.3V, kandi umuzunguruko mwinshi BUCK ukoreshwa mugutanga ingufu za ARM / FPGA / SDRAM, nibindi.;

[3] Intangiriro ya FPGA ikoreshwa na 1.2V, kandi ikoresha na sisitemu ya BUCK ikora neza;

[4] FPGA PLL ikubiyemo umubare munini wumuzunguruko, kugirango tumenye imikorere ya PLL, dukoresha LDO kugirango dutange imbaraga zisa na PLL;

[5] STM32F767IG itanga amashanyarazi yigenga yigenga kugirango itange voltage yerekana kuri chip ADC / DAC;

[6] Itanga gukurikirana ingufu n'ibipimo;

2.2 Ibiranga intwaro:

[1] Imikorere-ikomeye cyane STM32F767IG hamwe numurongo nyamukuru wa 216M;

[2] 14 kwaguka cyane I / O kwaguka;

[3] Kugwiza hamwe na I / O, harimo ARM yubatswe muri SPI / I2C / UART / TIMER / ADC nibindi bikorwa;

Harimo 100M Ethernet, interineti yihuta ya USB-OTG na USB kuri UART imikorere yo gukemura;

Harimo 32M SDRAM, ikarita ya TF, interineti ya USB-OTG (irashobora guhuzwa na U disiki);

[6] 6P FPC yo gukemura, adaptate isanzwe kugirango ihuze na rusange 20p;

[7] Gukoresha itumanaho rya bisi 16-bit;

2.3 Ibiranga FPGA:

[1] Altera yo mu gisekuru cya kane Cyclone ikurikirana FPGA EP4CE15F23C8N irakoreshwa;

[2] Kugera kuri 230-gukora cyane I / O kwaguka;

[3] FPGA yagura chip-chip SRAM ifite ubushobozi bwa 512KB;

[4] Uburyo bwo kuboneza: shyigikira JTAG, AS, PS uburyo;

[5] Shigikira gupakira FPGA ukoresheje ARM iboneza;AS imikorere ya PS igomba guhitamo binyuze mubasimbuka;

[6] Gukoresha itumanaho rya bisi 16-bit;

[7] Icyambu cya FPGA cyo gukuramo: icyambu cya FPGA JTAG;

2.4 Ibindi biranga:

[1] USB ya iCore4 ifite uburyo butatu bwo gukora: uburyo bwa DEVICE, uburyo bwa HOST nuburyo bwa OTG;

Ubwoko bwa interineti ya Ethernet ni 100M yuzuye duplex;

[3] Uburyo bwo gutanga amashanyarazi burashobora gutoranywa na jumper, USB ya USB ikoreshwa muburyo butaziguye, cyangwa binyuze mumutwe wa pin (5V itanga amashanyarazi);

[4] Utubuto tubiri twigenga tugenzurwa na ARM na FPGA;

[5] Amatara abiri ya LED yikibaho cya iCore4 ya heterogeneous dual-core yibikorwa bigenzura inganda bifite amabara atatu: umutuku, icyatsi nubururu, bigenzurwa na ARM na FPGA;

[6] Emera 32.768K pasiporo ya kristu kugirango itange RTC isaha nyayo kuri sisitemu;
