Initialization

Overview

Operations to initialize vectors and accumulators.

Functions
template<Elem E, unsigned Elems = native_vector_length_v<E>>
vector< operand_base_type_t< E >, Elems >	aie::broadcast (E a)
	Returns a vector whose elements are initialized to the given value.
template<Accum Acc, Accum... Accums> requires ((is_same_accum_v<Acc, Accums> && ...))
auto	aie::concat (const Acc &acc, const Accums &...accums) -> accum< typename Acc::value_type, Acc::size() *(1+sizeof...(Accums))>
	Concatenate the contents of all input accumulators into a larger accumulator.
template<Vector Vec, Vector... Vectors> requires ((is_same_vector_v<Vec, Vectors> && ...))
auto	aie::concat (const Vec &v, const Vectors &...vectors) -> vector< typename Vec::value_type, Vec::size() *(1+sizeof...(Vectors))>
	Concatenate the contents of all input vectors into a larger vector.
template<ElemBaseType T, unsigned Elems = native_vector_length_v<T>>
vector< T, Elems >	aie::zeros ()
	Returns a vector whose elements are initialized to zero.

Function Documentation

broadcast()

template<Elem E, unsigned Elems = native_vector_length_v<E>>

vector< operand_base_type_t< E >, Elems > aie::broadcast

(

E

a

)

Returns a vector whose elements are initialized to the given value.

for (unsigned i = 0; i < Elems; ++i)
    out[i] = a;

Template Parameters

E	Element type of the returned vector.
Elems	Size of the vector.

Parameters

a	Value. The type must meet aie::Elem.

concat() [1/2]

template<Accum Acc, Accum... Accums>
requires ((is_same_accum_v<Acc, Accums> && ...))

auto aie::concat	(	const Acc &	acc,
		const Accums &...	accums
	)		-> accum<typename Acc::value_type, Acc::size() * (1 + sizeof...(Accums))>

Concatenate the contents of all input accumulators into a larger accumulator.

All input accumulators must have the same type and size.

Parameters

acc	First input accumulator.
accums	Rest of input accumulators.

concat() [2/2]

template<Vector Vec, Vector... Vectors>
requires ((is_same_vector_v<Vec, Vectors> && ...))

auto aie::concat	(	const Vec &	v,
		const Vectors &...	vectors
	)		-> vector<typename Vec::value_type, Vec::size() * (1 + sizeof...(Vectors))>

Concatenate the contents of all input vectors into a larger vector.

All input vectors must have the same type and size.

Parameters

v	First input vector.
vectors	Rest of input vectors.

zeros()

template<ElemBaseType T, unsigned Elems = native_vector_length_v<T>>

vector< T, Elems > aie::zeros

(

)

Returns a vector whose elements are initialized to zero.

for (unsigned i = 0; i < Elems; ++i)
    out[i] = 0;

Template Parameters

E.	Element type of the returned vector.
Elems.	Size of the vector.
