Intel® C++ Compiler 16.0 User and Reference Guide
Converts a float32 vector into a float64 vector. The corresponding instruction is VCVTPS2PD. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern __m512d __cdecl _mm512_cvtpslo_pd(__m512 v2); |
With Mask extern __m512d __cdecl _mm512_mask_cvtpslo_pd(__m512d v1_old, __mmask8 k1, __m512 v2); |
v2 |
float32 vector used for the conversion operation |
v1_old |
Source vector that retains old values of the destination vector; the resulting vector gets corresponding elements from v1_old for zero mask bits |
k1 |
Writemask; only those elements of the source vectors with corresponding bit set to '1' in the k1 mask are computed and stored in the result; elements in the result vector corresponding to zero bit in k1 are copied from corresponding elements of vector v1_old |
Performs an element-by-element conversion of low half of float32 vector v2 elements to float64 vector. The resulting elements are overwritten in the result vector.
The masked variant has two additional arguments: v1_old and k1. Those elements of v2 with the corresponding bit clear in vector mask k1 are not used in the computation. Instead, the corresponding element from v1_old is copied to the resulting vector.
Returns the result of the conversion operation.
