Does ESP32 have instruction set to accelerated math computing?

Hi,
My project need to do more mathematical operations (e.g. multiplication, division, exponentiation ..).
Does ESP32 have instruction set to accelerated math computing?

Thanks.

The ESP32 has integer and (single-precision) floating point multiplication and division; no need to do anything special for those as GCC will automatically spit out the right instructions for that. There's also an 16-bit MAC instruction, but you may need to write some assembly for that.

Thank you @ESP_Sprite.

Does ESP32 support some features likes SIMD / NEON ?

Thanks.

No / hard to say. NEON is ARM-specific and SIMD is kinda vague. I know the MAC instruction is SIMD-ish, though.

Thank you @ESP_Sprite.

Now because of the SIMD/NEON, my applicatio could run fast on the arm platform.
On ESP32, it was a bit slow.
Would you please share any experience about accelerated math computing on ESP32 ?

Thanks.
