Elementwise Shifting

Description

Functions for shifting a Vec elementwise.

Functions
template<size_t COUNT, typename T , size_t SIMD_WIDTH>
static Vec< T, SIMD_WIDTH >	simd::alignre (const Vec< T, SIMD_WIDTH > &h, const Vec< T, SIMD_WIDTH > &l)
	Concatenates two Vec's, shifts the result right by a constant number of elements, and returns the low half of the result.
template<size_t COUNT, typename T , size_t SIMD_WIDTH>
static Vec< T, SIMD_WIDTH >	simd::slle (const Vec< T, SIMD_WIDTH > &a)
	Shifts a Vec left by a constant number of elements, shifting in zero elements.
template<size_t COUNT, typename T , size_t SIMD_WIDTH>
static Vec< T, SIMD_WIDTH >	simd::srle (const Vec< T, SIMD_WIDTH > &a)
	Shifts a Vec right by a constant number of elements, shifting in zero elements.

alignre()

template<size_t COUNT, typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::alignre ( const Vec< T, SIMD_WIDTH > & h, const Vec< T, SIMD_WIDTH > & l )

inlinestatic

Concatenates two Vec's, shifts the result right by a constant number of elements, and returns the low half of the result.

Template Parameters

COUNT

number of elements to shift by

Parameters

h	first Vec The high half of the concatenated Vec
l	second Vec The low half of the concatenated Vec

Returns

low half of the shifted concatenated Vec

slle()
