function bitreverse(const vec<T, N> &) shuffle¶

template <size_t groupsize = 1, typename T, size_t N>
KFR_INTRINSIC vec<T, N> bitreverse(const vec<T, N>& x)

Reorders the elements of a vector by reversing the bits of their indices.

A specialization of digitreverse with radix 2 (binary). Optionally supports grouped bit reversal.

Template parameters

groupsize	Number of elements per group before applying bit reversal.
T	The element type of the vector.
N	The number of elements in the vector.

Parameters

x	The input vector to be reordered.

Returns

A vector with bit-reversed indices.
