I-Xilinx Memory - I-Prom Yokucushwa yama-FPGAs

I-Xilinx yethula uchungechunge lwe-XC18V00 lwama-PROM ahlelekayo angaphakathi nohlelo (Umfanekiso 1).Amadivayisi akulo mndeni we-3.3V ahlanganisa i-4-megabit, i-2-megabit, i-megabit engu-1, ne-512-kilobit PROM ehlinzeka ngendlela esebenziseka kalula, engabizi kakhulu yokuhlela kabusha nokugcina ama-bitstreams okulungiselelwa kwe-Xilinx FPGA.

Uma i-FPGA ikumodi ye-Master Serial, ikhiqiza iwashi lokumisa elishayela i-PROM.Isikhathi esifushane sokufinyelela ngemva kokuvulwa kwe-CE ne-OE, idatha iyatholakala kuphinikhodi ye-PROM DATA (D0) exhunywe kuphinikhodi ye-FPGA DIN.Idatha entsha iyatholakala ngesikhathi sokufinyelela esifushane ngemva konqenqema lwewashi ngalinye elikhuphukayo.I-FPGA ikhiqiza inombolo efanelekile yama-pulses wewashi ukuze iqedele ukumisa.Uma i-FPGA ikumodi ye-Slave Serial, i-PROM ne-FPGA kuvalwe iwashi langaphandle.

Uma i-FPGA ikumodi ye-Master Khetha MAP, i-FPGA ikhiqiza iwashi lokumisa elishayela i-PROM.Uma i-FPGA ikumodi ye-Slave Parallel noma i-Slave Select MAP, i-oscillator yangaphandle ikhiqiza iwashi lokumisa elishayela i-PROM ne-FPGA.Ngemuva kokuthi i-CE ne-OE zinikwe amandla, idatha iyatholakala kumaphinikhodi we-PROM's DATA (D0-D7).Idatha entsha iyatholakala ngesikhathi sokufinyelela esifushane ngemva konqenqema lwewashi ngalinye elikhuphukayo.Idatha ivalwe ku-FPGA onqenqemeni olulandelayo olukhuphukayo lwe-CCLK.I-oscillator esebenza mahhala ingasetshenziswa kumodi ye-Slave Parallel noma i-Slave Select MAP.

Amadivayisi amaningi angenziwa nge-cascade ngokusebenzisa okukhiphayo kwe-CEO ukushayela okokufaka kwe-CE kwedivayisi elandelayo.Okokufaka kwewashi kanye nemiphumela ye-DATA yawo wonke ama-PROM kulolu chungechunge kuxhumene.Wonke amadivaysi ayasebenza futhi angakwazi ukukhishwa namanye amalungu omndeni noma nomndeni we-serial PROM wesikhathi esisodwa we-XC17V00.
