Data throughput from PSRAM to GPIO

Postby amirgeva » Thu May 21, 2020 9:03 am

I am trying to stream 8-bit data from PSRAM (data too large to fit in DMA'able RAM), to 8 GPIO pins.
Does any one have an idea of the maximum throughput that can be achieved, assuming one core is dedicated for this?
Streaming doesn't have to be hard real-time, but without large time gaps.
