Enhancement: ESP-DSP *really* needs high-performance sin()/cos() (DSP-70) about esp-dsp

Hi Dana,
Thank you for feedback.

The dsps_tone_gen_f32() was not designed to be optimized. is made to generate table in non real-time thread, or in initialization phase.

Anyway, I think we will implement optimized sin/cos functions soon.

Thank you for the feedback!

Hi @danak6jq the optimyzed sin/cos generator now in the esp-dsp.

Thank you, Dmitry - this is terrific news. I expected dsps_tone_gen_f32() was not intended as an optimized function, I was just using it as an example of an NCO. Optimized sin()/cos() would be terrific.

I wonder any updates on this issue? fast sin/cos would be great!

In my application, I evaluated the license terms of the CMSIS-DSP source and used the fast cos/sin function from that until ESP-DSP has this functionality

Thank you!
