AM3352: 如何達到gpmc最佳效能?

Part Number: AM3352


Hi Expert

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/656751/am3358-gpmc-throughput

這篇內容看起來是GPMC 如果使用DMA + burst mode(16-words)可以達到最佳效能

參考Linux kernel/Documentation/devicetree/bindings/memory-controllers/omap-gpmc.txt
GPMC device 必須是nand flash才能使用DMA

總結: 如果要達到GPMC最佳效能 FPGA必須模擬成 nand flash device 並支援 burst mode,AM3352端開啟DMA搭配burst read 才可以做到,這樣描述對嗎?

謝謝
