process structure in 1787 fast dsp FDSP
What is the process structure, with respect to number of bits in internal datapaths and memory and accumulator, used by the 1787 FDSP when executing a series of consecutive biquads? I imagine it is si

Pops when switching banks
Hi, I am currently working with ADAU 1787 fastDSP specifically with bank switching to change the gain in a smooth way. After trial and error, I have figured out that when switching banks, the Dynamic

Feedback loop doesn't work on ADAU1787 FastDSP
Hello, I am working with an EVAL-ADAU1787Z and want to create an algorithm containing a feedback loop in the FastDSP. However, I can't get it to work. For testing I'm trying to implement the simplest

Loading filter coefficients to the FastDSP of a ADAU1787 in SigmaStudio
Hello, I'm working with an EVAL-ADAU1787Z evaluation board in SigmaStudio 4.7. So far I've been using the SigmaDSP to do my signal processing. I now want to move the biquad filtering in my signal chai

Soft clipper in the ADAU1787 fast DSP
The toolbox for the ADAU1787 fast DSP does not include a soft clipper, yet it seems possible to implement a standard cubic soft clipper with a set of more basic toolbox elements (I can send a SigmaStu

''Discrete'' RMS Table block for specific needs/settings (IEC 61672 fast and slow time weighting)
Hi All, I need the functionality of the RMS table block (Level Detectors/Lookup Tables > RMS Table > Range (-93 to +3 dB) > RMS Table), but for my application the available dB/s range and precision is

Toggle mute on EVAL-ADAU1787z
Hi, I see that for the SigmaDSP, there are many blocks that can be controlled via GPIOs on the board. For the FastDSP, there don't really seem to be any. Is there any way to simply toggle a mute block

How to update fastDSP parameters with the sigmaDSP?
Hi, I have an EVAL-ADAU1787z and I'm trying to build an application in sigma studio where I can update the biquad parameters on the fastDSP from the sigmaDSP. From the manual I can read this: "There i

Update parameters on the FastDSP with the SigmaDSP
Hi, I just received a development board for the new ADAU1787 (EVAL-ADAU1787Z). As I understand it I should be able to update parameters on the FastDSP, with the SigmaDsp. Meaning I should be able to w

EVAL-ADAU1787 FastDSP Setup
Hi, I am audio programmer with DSP experience but new to embedded systems. I am working with the EVAL-ADAU1787 and got the SigmaDSP on SigmaStudio path working but haven't managed to do the same with
