I impelemnted a design composed of a softcore processor (RISC-V based), on a Nexys 4 DDR (Nexys A7) board. The software is stored in the DDR2 Memory. The software accesses the DDR2 memory through a controller interface.
Now, I'd like to add an Audio IP that can fetch some audio samples, stored in a specific location (by the processor) in the DDR2 memory, and feed them to the audio output. However, since the interface is taken by the processor, is there a way to use that interface by the audio driver too? I read about something called the Ping Pong PHY, but apparently it is only
