Instruction
VEXP2PS zmm, zmm {sae}
Synopsis
_mm512_exp2a23_round_ps(__m512 a, int sae);
Description
Compute the approximate exponential value of 2 raised to the power of packed single-precision (32-bit) floating-point elements in "a", and store the results in "dst". The maximum relative error for this approximation is less than 2^-23. [sae_note]
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := POW(FP32(2.0), a[i+31:i])
ENDFOR
dst[MAX:512] := 0
