Hi everyone.

I have a problem with implement Echo Cancellation Noise Reduction by ADAU1462.

Actually I just develope it by hardware, not software.

And I requested it to software agency for the implementation of ECNR.

They can't make it and they say that if they use their solutions, it works.

But when they use Sigma Studio for implement it, it doesn't work.

So I want to know how to solve that problem, and there's how we used.

software

ECNR

Hello Mohal,

We will need a little more info on what your hardware setup it like and what your intentions are?

I see you have the Start pulse set to use the serial input 0 rate. So what is coming into serial input port 0? Is it setup as a master or slave? If there is no clock there then the DSP program will not run because there will be no start pulse to trigger the program to run.

Then you have serial output port 0 setup to slave to serial output port 0. Are there any clocks connected to those pins?

Also, I want to point out that input clock domains 0-3 are NOT connected to output clock domains 0-3. They are separate clock domains so, for instance, if you want to slave an output port to an input port then you have to physically connect the two ports external to the part.

So I will need to know more about your hardware setup and clocking systems and it would be good to also see the project.

Thanks!
