Hi All,

Can anyone tell me about the concept of ping-pong buffer. Whether its a circular buffers including minimum of two buffers?
How it is working..? I am planing to include ping pong buffer in my DAQ IP design. its acquires samples from ADC.

It is basically a double-buffering method that improves transfer speed.

So while data is filling buffer1, you read the data out from the buffer2 (already filled before from buffer1).
Then when buffer1 is ready you read it and again fill buffer2.
