Function Documentation

load() [1/2]

template<size_t SIMD_WIDTH, typename T >

static Vec< T, SIMD_WIDTH > simd::load ( const T *const p )

inlinestatic

Loads a Vec from aligned memory.

The memory location must be aligned to the SIMD_WIDTH.

Note

The template argument order of T and SIMD_WIDTH is reversed so that T can be omitted in instantiation.

Parameters

[in]

p

pointer to the aligned memory location to load from

Returns

Vec with the loaded values

load() [2/2]

template<typename T , size_t SIMD_WIDTH>

static void simd::load ( const T *const p, Vec< T, SIMD_WIDTH > inVecs[], size_t numInVecs )

inlinestatic

Loads multiple successive Vec's from aligned memory.

The memory location must be aligned to the SIMD_WIDTH.

Parameters

[in]	p	pointer to the aligned memory location to load from
[out]	inVecs	array of Vec's to store the loaded values in
	numInVecs	number of Vec's to load

loadu() [1/2]

template<size_t SIMD_WIDTH, typename T >

static Vec< T, SIMD_WIDTH > simd::loadu ( const T *const p )

inlinestatic

Loads a Vec from unaligned memory.

In contrast to load(const T *const p), the memory location does not need to be aligned to any boundary.

Note

The template argument order of T and SIMD_WIDTH is reversed so that T can be omitted in instantiation.

Parameters

[in]

p

pointer to the memory location to load from

Returns

Vec with the loaded values

loadu() [2/2]

template<typename T , size_t SIMD_WIDTH>

static void simd::loadu ( const T *const p, Vec< T, SIMD_WIDTH > inVecs[], size_t numInVecs )

inlinestatic

Loads multiple successive Vec's from unaligned memory.

In contrast to load(const T *const, Vec<T, SIMD_WIDTH>[], size_t), the memory location does not need to be aligned to any boundary.

Parameters

[in]	p	pointer to the memory location to load from
[out]	inVecs	array of Vec's to store the loaded values in
	numInVecs	number of Vec's to load
