i use the biquadCascade from sc_dsp_filter like this:
Code: Select all
for (int i=0;i<number_of_fifos;i+=2)
{
unsigned sample;
sample = media_output_fifo_pull_sample(ofifos[i], timestamp);
samples_output <: (unsigned) biquadCascade(bs_l, (signed) sample);
}
for (int i=1;i<number_of_fifos;i+=2)
{
unsigned sample;
sample = media_output_fifo_pull_sample(ofifos[i], timestamp);
samples_output <: (unsigned) biquadCascade(bs_r, (signed) sample);
}
Code: Select all
Constraint check for "stdcore[0]" (node "0", core 0):
Stack available: 0x00007638, used: 0x00002304 . OKAY
Threads available: 8, used: 6+. MAYBE
Timers available: 10, used: 6+. MAYBE
Chanends available: 32, used: 21+. MAYBE
Constraints checks PASSED WITH CAVEATS.
since the biquad is not working yet and i only get those constraints when i use the biquadCascade, i assumed that these things are correlated.
but how can i get rid of this uncertainty?
