  • x86 _mm_sign_epi8(_m128i a,_m128i b) intrinsic NEON equivalent
    I have the x86 intrinsic (_m128i _mm_sign_epi8(_m128i a,_m128i b)) it performs the following task: for (i = 0; i < 16; i++) { if (b[i] < 0) { r[i] = -a[i]; } else if (b[i] == 0) { r[i] = 0; } else { r...

  • Is NEON Floating Point (VFP) Only?
    Referring to the diagram below, it appears that NEON only applies to floating point processing. Is this correct? Does it mean that NEON only applies to using the VFP? Does it mean that NEON does not apply...
