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

1787 FDSP number of instructions
What controls the number of instructions available per frame in the 1787 FDSP core? Is the number always 64, or will it sometimes be less than that? The datasheet says "The core is controlled with a 2

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

ADAU1787 test: adc2/3 to fdsp to dac
I just got an adau1787 eval kit and am trying a simple test to run audio from adc input through the fdsp to the dac output. See the attached dspproj. I get audio out if I route the adc2 input directly

1787: Choosing 768 kHz in SS results in compile error.
I am trying to change the sample rate so the FDSP runs at 768 kHz. I have changed the DAC_FS and ADC01_FS registers to 768 kHz, however when I change this setting in SS and 'link-compile-download', I
