Memory ya Xilinx - Zosintha Zosintha za FPGAs

Xilinx imayambitsa XC18V00 mndandanda wa ma PROM osinthika mu dongosolo (Chithunzi 1).Zipangizo za m'banja la 3.3V ili ndi 4-megabit, 2-megabit, 1-megabit, ndi PROM ya 512-kilobit zomwe zimapereka njira yosavuta, yotsika mtengo yokonzanso ndikusunga ma bitstreams a Xilinx FPGA.

FPGA ikakhala mu Master Serial mode, imapanga wotchi yosinthira yomwe imayendetsa PROM.Kufikira kwakanthawi kochepa CE ndi OE zitayatsidwa, deta imapezeka papini ya PROM DATA (D0) yomwe imalumikizidwa ndi pini ya FPGA DIN.Zatsopano zimapezeka pakangopita nthawi yochepa pambuyo pa wotchi iliyonse yokwera.FPGA imapanga kuchuluka koyenera kwa mawotchi kuti amalize kasinthidwe.Pamene FPGA ili mu Slave Serial mode, PROM ndi FPGA zimatsekedwa ndi wotchi yakunja.

FPGA ikakhala mu Master Select MAP mode, FPGA imapanga wotchi yosinthira yomwe imayendetsa PROM.Pamene FPGA ili mu Slave Parallel kapena Slave Select MAP mode, oscillator yakunja imapanga wotchi yosinthira yomwe imayendetsa PROM ndi FPGA.CE ndi OE zitayatsidwa, deta imapezeka pazikhomo za PROM's DATA (D0-D7).Zatsopano zimapezeka pakangopita nthawi yochepa pambuyo pa wotchi iliyonse yokwera.Detayo imayikidwa mu FPGA pamzere wotsatira wa CCLK.Oscillator yaulere itha kugwiritsidwa ntchito munjira za Slave Parallel kapena Slave Select MAP.

Zida zingapo zitha kusinthidwa pogwiritsa ntchito zotulutsa za CEO kuyendetsa kuyika kwa CE pazida zotsatirazi.Zolowetsa wotchi ndi zotulutsa za DATA za ma PROM onse mumndandandawu ndizolumikizana.Zipangizo zonse zimagwirizana ndipo zimatha kusinthidwa ndi mamembala ena a m'banjamo kapena ndi XC17V00 ya nthawi imodzi yokonzekera serial PROM banja.
