Synopsis
_mm512_conj_pch(__m512h a);
Description
Compute the complex conjugates of complex numbers in "a", and store the results in "dst". Each complex number is composed of two adjacent half-precision (16-bit) floating-point elements, which defines the complex number "complex = vec.fp16[0] + i * vec.fp16[1]", or the complex conjugate "conjugate = vec.fp16[0] - i * vec.fp16[1]".
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := a[i+31:i] XOR FP32(-0.0)
ENDFOR
dst[MAX:512] := 0
