NAME¶
std::experimental::simd - std::experimental::simd
Synopsis¶
Defined in header <experimental/simd>
template< class T, class Abi = simd_abi::compatible<T> >
(parallelism TS v2)
class simd;
The class template simd is a data-parallel type. The width of a given simd
instantiation is a constant expression, determined by the template
parameters.
An ABI tag is a type in the simd_abi namespace that indicates a choice of
size and
binary representation for objects of data-parallel type.
Template parameters¶
T - element type; an arithmetic type other than bool
Abi - tag type used to determine the number of elements and storage
Helper alias templates
template< class T, int N >
using fixed_size_simd = std::experimental::simd<T,
std::experimental::simd_abi::fixed_size<N>>;
template< class T >
using native_simd = std::experimental::simd<T,
std::experimental::simd_abi::native>;
