DMA restrictions

0

Hi,

I want to write two different registers/memory parallelly using DMA. I tried using multithreading concept. But writing is not happening as expected. I mean there is a time delay. How to avoid it? and Is it possible to write both registers/memory at the same time using DMA using multithreading concept?

Thank you

Hi,

There many things that need to be aligned. The very basic question is how does the FPGA logic gets laid out if your design. if there is only one interface given to the DMA, or only one interface implemented for register/memory access. I don't see how simultaneous concurrent accesses can happen, without diving into the complexity of SW layer above.

Thanks,
