• summary of NEON-intrinsics for ARMv8?
    Hello, is there a summery of NEON-instrinsics vor ARMv8 (specialy for AARCH64?) like this one ARM Information Center ? I only found a this pdf: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0073a...
  • 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...
