hello, I just check the speed of data transfer between ps and pl.
I use AXI-Stream interface with DMA Module.
I made a simple module that takes data from the dram and stores it back in the dram.
And I check transfer speed with various burst width and TDATA width.
This is my result.
I use pynq-z2 board and, I give 525Mhz to DDR in ps’ clock configuration option.
Also, I give 100Mhz to axi DMA module.
Is there a way to send and receive data faster than the current speed?
