Intel® C++ Compiler 16.0 User and Reference Guide
Calculates the sine and cosine values. Vector variant of sincos(x, &sin_x, &cos_x) function for a 128-bit/256-bit vector with float64 values.
extern __m128d _mm_sincos_pd(__m128d *p_cos, __m128d v1); |
extern __m256d _mm256_sincos_pd(__m256d *p_cos, __m256d v1); |
*p_cos |
points to vector of cosine results (pointer must be aligned on 16 bytes, or declared as __m128d* instead) |
v1 |
vector with float64 values |
Calculates sine and cosine values of vector v1 elements.
The cosine and sine values cannot be returned in the result vector. Therefore, the intrinsic stores the cosine values at a location pointed to byp_cos, and returns only the sine values in the 128-bit result vector.
128-bit/256-bit vector with the sine results.
Many routines in the svml library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
