Hello:

Complete noob to sigmastudio here, wondering if anyone can tell me how to display/read the coefficients of an adaptive filter (e.g., NLMS).

Thanks,

HH

Hi HH:

The quickest way is to find the memory locations for the coefficients being adapted, then use readback window to read them. The read-write window can be found when right clicking the DSP in the HW tab. The addresses can be found in the output files generated after Link-Compile-Download.

Please let us know if this is unclear.

Hi Miguel:

Yes, that helped. I found I can also see the coefficients in the "Capture" window, but the ReadWrite window has the advantage of saving to a file.
