Function

Returns the Stride object that describes the memory access stride, which corresponds to the dimension information of Shape.

Prototype

__aicore__ inline constexpr decltype(auto) GetStride() {}    
__aicore__ inline constexpr decltype(auto) GetStride() const {}

Parameters

None

Returns

Stride object that describes the memory access stride. The structure type (alias of the Std::tuple type) is defined as follows:

template <typename... Strides>
using Stride = Std::tuple<Strides...>;

Restrictions

None

Example

// Initialize the Layout data structure and obtain the corresponding value.
AscendC::Shape<int,int,int> shape = AscendC::MakeShape(10, 20, 30);
AscendC::Stride<int,int,int> stride = AscendC::MakeStride(1, 100, 200);

auto layoutMake = AscendC::MakeLayout(shape, stride);
AscendC::Layout<AscendC::Shape<int, int, int>, AscendC::Stride<int, int, int>> layoutInit(shape, stride);

int value = AscendC::Std::get<0>(layoutInit.GetStride()); // value = 1
value = AscendC::Std::get<1>(layoutInit.GetStride()); // value = 100
value = AscendC::Std::get<2>(layoutInit.GetStride()); // value = 200
