Member Function Documentation

◆ configure()

void configure ( const ITensor input,
ITensor output 
)

Set input, output tensors.

Parameters
[in]inputSource tensor. Data type supported: QASYMM8/QSYMM8/QSYMM16.
[out]outputDestination tensor with the same dimensions of input. Data type supported: F16/F32.

◆ name()

const char* name ( ) const
inlineoverridevirtual

Name of the kernel.

Returns
Kernel name

Implements ICPPKernel.

Definition at line 37 of file NEDequantizationLayerKernel.h.

38  {
39  return "NEDequantizationLayerKernel";
40  }

◆ operator=() [1/2]

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

◆ operator=() [2/2]

Default move assignment operator.

◆ 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.

Implements ICPPKernel.
