Detailed Description

Kernel to perform col2im reshaping.

Rearranges each matrix column into image blocks. It's the inverse operation of cpu::kernels::CpuIm2ColKernel.

For example, a vector of 9 elements can be reshaped to a block(image) of 3x3:

\[ \left( \begin{array}{ccccccccc} a0 & a1 & a2 & a3 & a4 & a5 & a6 & a7 & a8 \\ \end{array} \right) \rightarrow \left( \begin{array}{ccc} a0 & a1 & a2 \\ a3 & a4 & a5 \\ a6 & a7 & a8 \\ \end{array} \right) \]

◆ NECol2ImKernel() [1/3]

Default constructor.

Referenced by NECol2ImKernel::name().

◆ NECol2ImKernel() [2/3]

NECol2ImKernel ( const NECol2ImKernel )
delete

Prevent instances of this class from being copied (As this class contains pointers)

◆ NECol2ImKernel() [3/3]

NECol2ImKernel ( NECol2ImKernel &&  )
default

Member Function Documentation

◆ configure()

void configure ( const ITensor input,
ITensor output,
const Size2D convolved_dims 
)

Set the input and output of the kernel.

Parameters
[in]inputThe input tensor to convert. Data types supported: All
[out]outputThe output tensor. 3 lower dimensions represent a single output [width, height, OFM], while the rest represent batch of outputs. Data types supported: Same as input
[in]convolved_dimsOutput convolved dimensions.

◆ name()

const char* name ( ) const
inlineoverridevirtual

◆ operator=() [1/2]

NECol2ImKernel& operator= ( const NECol2ImKernel )
delete

Prevent instances of this class from being copied (As this class contains pointers)

Referenced by NECol2ImKernel::name().

◆ operator=() [2/2]

NECol2ImKernel& operator= ( NECol2ImKernel &&  )
default

Allow instances of this class to be moved.

◆ run()

void run ( const Window window,
const ThreadInfo info 
)
overridevirtual

Execute the kernel on the passed window.

Warning
If is_parallelisable() returns false then the passed window must be equal to window()
Note
The window has to be a region within the window returned by the window() method
The width of the window has to be a multiple of num_elems_processed_per_iteration().
Parameters
[in]windowRegion on which to execute the kernel. (Must be a region of the window returned by window())
[in]infoInfo about executing thread and CPU.

Reimplemented from ICPPKernel.

◆ validate()

static Status validate ( const ITensorInfo input,
const ITensorInfo output,
const Size2D convolved_dims 
)
static

Static function to check if given info will lead to a valid configuration of NECol2ImKernel.

Parameters
[in]inputThe input tensor to convert. Data types supported: All
[in]outputThe output tensor. 3 lower dimensions represent a single output [width, height, OFM], while the rest represent batch of outputs. Data types supported: Same as input
[in]convolved_dimsOutput convolved dimensions.
Returns
a status
