Synopsis
_mm512_rsqrt23_ps(__m512 a);
Description
Calculates the reciprocal square root of packed single-precision (32-bit) floating-point elements in "a" to 23 bits of accuracy and stores the result in "dst".
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := Sqrt(1.0 / a[i+31:i])
ENDFOR
dst[MAX:512] := 0
