Tarik: Alot of it depends on at what datarate you want to send things out. The DAC (AD9122) on the FMCOMMS1 is capable of being fed at 16-BIT, 1200 MSPS, for I and Q. That's over 4800 Mbytes/second....

Dear Robin, I understand you. I would like to get tips how to enable continuous streaming. I am aware that axi_ad9122_dma is currently set to repeat sending same data from DDR. That is not what I need....
View ArticleRe: Interfacing PS and PL (streaming data from PS to PL)
Tarik: There are things in the FMCOMMS3, which are done at lower datarate, which do that. As one buffer is being drained, userspace fills up another, and things ping/pong back and forth. However - for...
