Intel® C++ Compiler 16.0 User and Reference Guide
Calculates exponential value of one argument raised to the other argument. Vector variant of pow(x, y) function for a float32 argument. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern _m512 __cdecl _mm512_pow_ps(_m512 v2, _m512 v3); |
With Mask extern _m512 __cdecl _mm512_mask_exp2_ps(_m512 v1_old, __mmask16 k1, _m512 v2, _m512 v3); |
v2 |
vector with float32 values |
v3 |
vector with float32 values |
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 |
Calculates the exponential value of each vector v2 element raised to the power of the corresponding vector v3 element.
The masked variant has two additional arguments: v1_old and k1. Those elements of v2 and v3 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 operation.
