Searchable:

AVX_ALL-Elementary Math Functions-YMM

Register:

YMM 256 bit

Return Type:

__m256

Param Types:

__m256 a

Param ETypes:

FP32 a

__m256 _mm256_rcp_ps(__m256 a);

Intel Description

Compute the approximate reciprocal 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 1.5*2^-12.

Intel Implementation Psudeo-Code

FOR j := 0 to 7
        i := j*32
        dst[i+31:i] := 1.0 / a[i+31:i]
ENDFOR
dst[MAX:256] := 0

__m256 _mm256_rsqrt_ps(__m256 a);

Intel Description

Compute the approximate reciprocal square root 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 1.5*2^-12.

Intel Implementation Psudeo-Code

Intel Description

Compute the square root of packed double-precision (64-bit) floating-point elements in “a”, and store the results in “dst”.

Intel Implementation Psudeo-Code

FOR j := 0 to 3
