What does "normal" have to do with it? SIMD means single instruction, multiple data, which is how these instructions are designed.
replyHow does using instructions that operate on multiple data elements, which make your software 3 times faster, not fit the definition of SIMD-accelerated?
replyBecause these are normal instructions.
replyIf you do multiplication using mul instead of loop and add, is it acceleration too?
Yes.
replyThe article would then be "MUL-accelerated multiplication". Obviously any modern compiler should not require a developer to make that optimization.
What does "normal instructions" mean? I don't see (or missed) a heading with "Normal" in the ESP32 docs.
Edit: Or are you saying the instruction called out by the author is not SIMD?
