Intel® C++ Compiler XE 13.1 User and Reference Guides
Approximates the reciprocals of the float32 elements to 23 bits of accuracy. Corresponding instruction is VRCP23PS. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern __m512 __cdecl _mm512_rcp23_ps(__m512 v2); |
With Mask extern __m512 __cdecl _mm512_mask_rcp23_ps(__m512 v1_old, __mmask16 k1, __m512 v2); |
v2 |
float32 vector used for the 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 |
Approximates the reciprocals of the float32 vector v2 elements to 23 bits of accuracy.
The masked variant has one additional argument: k1. Only those elements in the source registers with the corresponding bit set in vector mask k1 are used for computing.
Returns the result of the operation.
