Detailed Description

template<class _ioElementOperationType, class _vectorElementOperationType>
class VioViVi< _ioElementOperationType, _vectorElementOperationType >

Implement operation of the form \(v_{io} = op_{io}(v_{io}, op_{vv}(v_{i1}, v_{i2}))\) for fixed size vectors.

This class uses template specialization to perform store-back vector-vector-vector operations

\[v_{io} = \mathrm{op_{io}}(V_{io}, \mathrm{op_{vv}}(v_{i1}, v_{i2})) \]

where \(v_{io}\) is an input-output (store-back) vector; \(v_{i1}\) and \(v_{i2}\) are input vectors. A typical example is: \(v_{io} += v_{i1} \cdot v_{i2}\). The vectors have a fixed size, determined at compilation time; \(op_{vv}\) is an element wise operation between the elements of \(v_{i1}\) and the elements of \(v_{i2}\); \(op_{io}\) is an operation between the output of \(op_{vv}\) and the elements of \(v_{io}\).

Parameters

_ioOperationType	The type of the store-back operation.
_vectorElementOperationType	The type of the operation between scalar and input vector.

void VioViVi< _ioElementOperationType, _vectorElementOperationType >::Unfold ( _ioVectorType & ioVector, const _inputVectorType1 & vector1, const _inputVectorType2 & vector2 )

inlinestatic

Unfold the recursion. Performs the operation _elementOperationType elementwise on the last elements of the input vector and the input scalar and call Unfold for the _size - 1 elements left (i.e. unfold the recursive calls). The incremental operation is applied to the result of the recursive Unfold call and the result of _elementOperationType(inputVector[_size], inputScalar[_size]).

Parameters

inputVector	The input vector (first operand for _elementOperationType).
inputScalar	The input scalar (second operand for _elementOperationType).
