very interesting, do you have a pointer with more info on what kind of SIMD support it has?

- bobmcnamara 5mo agoHopefully comparable or better than ESP32S3. But with the weird alignment thing fixed
- throwaway81523 5mo agoWhy on earth SIMD instead of the risc-v vector extensions that are supposed to be better?
- andynerd 5mo agoFor compatibility and simplicity. Most SIMD instructions in P4 and S31 (compatible with P4 rev 3.x) are an direct evolution from S3. Espressif just doesn't want to rewrite their optimized assembly libraries.
- andylinpersonal 5mo agoThe same as P4 rev 3.x, which is still undocumented. Assembler source and esp-nn/esp-dsp are your friend. Some people have also tried some stuff. And HP core 0 is scalar-only now.
