Detailed Description

template<class _incrementalOperationType, class _elementOperationType>
class SoViVi< _incrementalOperationType, _elementOperationType >

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

This class uses template specialization to perform incremental binary vector operations of the form

\[s_o = \mathrm{op_{incr}(\mathrm{op}(v_{i1}, v_{i2}))} \]

where \(v_{i1}\) and \(v_{i2}\) are the input vectors and \(s_o\) is the scalar output. The vectors have a fixed size, determined at compilation time, op stands for the unary operation performed elementwise on \(v_{i1}\) and \(v_{i2}\) and whose result are used incrementally as input for \(op_{incr}\). For a vector of size 3, the result is \(s_o = op_{incr}(op_{incr}(op(v1[1], v2[1]), op(v1[0], v2[0])), op(v1[2], v2[2]))\).

Parameters

_incrementalOperationType	The type of the incremental operation.
_elementOperationType	The type of the unary operation.

OutputType SoViVi< _incrementalOperationType, _elementOperationType >::Unfold ( const _input1VectorType & input1Vector, const _input2VectorType & input2Vector )

inlinestatic

Unfold the recursion. Performs the operation _elementOperationType elementwise on the last elements of the input vectors 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(input1Vector[_size], input2Vector[_size]).

Parameters

input1Vector	The first input vector (first operand for _elementOperationType).
input2Vector	The second input vector (second operand for _elementOperationType).
