Member Function Documentation

◆ configure()

void configure ( const ITensorInfo src,
ITensorInfo dst 
)

Set the input and output tensors.

Parameters
[in]srcSource tensor info. The dimensions over the third will be interpreted as batches. Data types supported: QASYMM8/QASYMM8_SIGNED/F32/F16.
[out]dstDestination tensor info with the same dimensions of input. Data types supported: QASYMM8/QASYMM8_SIGNED/QASYMM16

◆ run()

void run ( ITensorPack tensors)
overridevirtual

Run the kernels contained in the function.

Parameters
[in]tensorsVector that contains the tensors to operate on.

Reimplemented from INEOperator.

58 }
virtual void schedule_op(ICPPKernel *kernel, const Hints &hints, const Window &window, ITensorPack &tensors)=0
Runs the kernel in the same thread as the caller synchronously.

◆ validate()

Status validate ( const ITensorInfo src,
const ITensorInfo dst 
)
static

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

Similar to CpuQuantize::configure()

Returns
a status
