I need to move data from FPGA memory to DDR memory. For other projects I have:
> DDR working with MicroBlaze, thanks for the help
- (https://forum.digilentinc.com/topic/17948-place-30-172-sub-optimal-placement-for-a-clock-capable-io-pin-and-pll-pair/)
> Memory IP's (dualport and fifo) working from FPGA to AXI_GPIO to MicroBlaze
For a new project I need the copy from FPGA memory to DDR memory to be fast (48MB/sec).
I think:
(a) FPGA direct to DDR may work better, but from other posts it is difficult to setup and tune?
(b) If "DMA from IP memory to DDR memory" is possible:
- Might it be fast enough?
- Are there any example or clues?
