Detailed Description

template<typename Type>
struct dsp::SIMDRegister< Type >

A wrapper around the platform's native SIMD register type.

This class is only available on SIMD machines. Use JUCE_USE_SIMD to query if SIMD is available for your system.

SIMDRegister<Type> is a templated class representing the native vectorized version of FloatingType. SIMDRegister supports all numerical primitive types and std:complex<float> and std::complex<double> supports and most operations of the corresponding primitive type. Additionally, SIMDRegister can be accessed like an array to extract the individual elements.

If you are using SIMDRegister as a pointer, then you must ensure that the memory is sufficiently aligned for SIMD vector operations. Failing to do so will result in crashes or very slow code. Use SIMDRegister::isSIMDAligned to query if a pointer is sufficiently aligned for SIMD vector operations.

Note that using SIMDRegister without enabling optimizations will result in code with very poor performance.

static ElementType * dsp::SIMDRegister< Type >::getNextSIMDAlignedPtr ( ElementType * ptr )

staticnoexcept

Returns the next position in memory where isSIMDAligned returns true.

If the current position in memory is already aligned then this method will simply return the pointer.
