Detailed Description

template<typename Ty, int N>
class sycl::_V1::ext::intel::esimd::simd< Ty, N >

The main simd vector class.

A vector of elements, which compiler tries to map to a GPU register. Supports all standard C++ unary and binary operations. See more details in the base class' docs: detail::simd_obj_impl.

Template Parameters
Tyelement type. Can be any C++ integer or floating point type or sycl::half.
Nthe number of elements.

◆ operator sycl::ext::oneapi::experimental::simd< Ty, N1 >()

template<typename Ty , int N>
template<int N1, class Ty1 = Ty, class SFINAE = std::enable_if_t< (N1 == N) && (N1 <= std::experimental::simd_abi::max_fixed_size< Ty>)&&!detail::is_wrapper_elem_type_v<Ty1>>>
sycl::_V1::ext::intel::esimd::simd< Ty, N >::operator sycl::ext::oneapi::experimental::simd< Ty, N1 > ( )
inline

Implicitly converts this object to a sycl::ext::oneapi::experimental::simd object.

Available when the number of elements does not exceed maximum fixed size of the oneapi's simd_abi and (TODO, temporary limitation) the element type is a primitive type (e.g. can't be sycl::half).

Definition at line 125 of file simd.hpp.

◆ operator To()

sycl::_V1::ext::intel::esimd::simd< Ty, N >::operator To ( ) const
inline

Converts this object to a scalar.

Available when

  • this object's length is 1
  • To is a valid simd element type
    Template Parameters
    Tothe scalar type
    Returns
    this object's single element value converted to the result type.
