The definition is in RDCN file.

RDCN is used to shrink the size of an input.

It can be used both for NeighbourOP and GlobalNeighbourOP.

Template Parameters

DownSmplOP	downsampling function to shrink an input
LHS	is the input
RHS	is the filter2d node
Cols	determines the column size of the output
Rows	determines the row size of the output
LfType	determines the type of the leafNode {Buffer2D, Buffer1D, Host, Image}
LVL	the level of the node in the expression tree

sub_expression_evaluation

This function is used to break the expression tree whenever necessary. The decision for breaking the tree will be determined based on the static parameter called SubExpressionEvaluationNeeded. When this is set to true, the sub_expression_evaluation is called recursively from the root of the tree. Each node based on their parent decision will decide to launch a kernel for itself. Also, they decide for each of their children whether or not to launch a kernel separately. template parameters:

Template Parameters

ForcedToExec	: a boolean value representing the decision made by the parent of this node for launching a kernel.
LC	is the column size of local memory required by Filter2D and DownSmplOP
LR	is the row size of local memory required by Filter2D and DownSmplOP
LCT	is the column size of workgroup
LRT	is the row size of workgroup
DeviceT	type representing the device function parameters:

Parameters

dev	: the selected device for executing the expression

Returns: LeafNode
