Function splitpairs¶

`function` splitpairs(const vec<T, N> &) simd ¶

template <size_t group = 1, typename T, size_t N, size_t size = N / group, size_t side1 = 2,
          size_t side2 = size / side1>
KFR_INTRINSIC vec<T, N> splitpairs(const vec<T, N>& x)

Deinterleaves adjacent pairs (inverse of interleavehalves with side1 == 2).

Groups adjacent lanes into pairs and reorders so that all first elements of each pair precede all second elements.

Template parameters
group	Number of lanes in each block.
T	Element type of the vector.
N	Input vector length.
size	Number of groups, equals `N` / `group.`
side1	Number of elements per pair, fixed at 2.
side2	Number of pairs, equals `size` / `side1.`

Parameters
x	Source vector.

Returns
	A vector of length `N` with adjacent pairs split apart.

Fully qualified name: kfr::splitpairs(const vec<T, N> &)
