◆ configure()

void configure ( const ITensorInfo src,
unsigned int  depth_offset,
ITensorInfo dst 
)

Configure kernel for a given list of arguments.

Parameters
[in]srcSource tensor info. Data types supported: QASYMM8/QASYMM8_SIGNED/F16/F32.
[in]depth_offsetThe offset on the Z axis.
[in,out]dstDestination tensor info. Data types supported: Same as src.
Note
: The output tensor's low two dimensions can't be smaller than the input one's.
: The gaps between the two lowest dimensions of input and output need to be divisible by 2.

◆ name()

const char * name ( ) const
overridevirtual

Name of the kernel.

Returns
Kernel name

Implements ICPPKernel.

203  return "CpuConcatenateDepthKernel";
204 }

◆ run_op()

void run_op ( ITensorPack tensors,
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]tensorsA vector containing the tensors to operate on.
[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.
