I have one question about the Crossover block, as title, I got this testing on my ADAU1452 EVB as below:
From the 1452 spec, I know that if I use none block testing(the testing only has DSP 1452 and codec, no algorithm inside),
the measurement time is 1.26ms (input to output total time).
The above test, I measure the input to output total time, I got 4.4ms,
the testing environment:
I want to check which block will increase so much time, so I do this test on my EVB, only one Crossover block:
and the Crossover block I use:
the parameter of the crossover block:
After this test, I got the result, the total time increase to 4.32ms:
So my question is:
Why does the "Crossover" block will increase so much time? Is the algorithm design or something that I miss?
Thank you for reading this topic, hope you guys can help me
