If so I would suggest correcting the Table 1.5-1 of the ESP32-s3 TRM. The BR registers are not listed here which is confusing.

Sorry to restart an old thread. Does this mean that:

1. For the xtensa lx7 instruction set the boolean instructions like OLT.S, BT, BF, etc. are unavailable for the ESP32-S3. If so can you provide example code for the feature set that replaces this functionality?

2. You state that each core has ...

Sorry for restarting an old thread. I am aware we can do:

IFFT(data) = 1/N * conj(FFT(conj(data)))

However for efficiency a dedicated IFFT function would be better. Looking at the math the difference other than the 1/N scaling factor is as "simple" as a sign flip for the exponent of "e" from ...
