◆ configure()

void configure ( const ITensorInfo src0,
const ITensorInfo src1,
ITensorInfo dst,
ConvertPolicy  policy 
)

Initialise the kernel's input, dst and border mode.

Valid configurations (src0,src1) -> dst :

  • (U8,U8) -> U8
  • (S16,S16) -> S16
  • (S32,S32) -> S32
  • (F16,F16) -> F16
  • (F32,F32) -> F32
  • (QASYMM8,QASYMM8) -> QASYMM8
  • (QASYMM8_SIGNED,QASYMM8_SIGNED) -> QASYMM8_SIGNED
  • (QSYMM16,QSYMM16) -> QSYMM16
Parameters
[in]src0First input tensor info. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/QSYMM16/F16/S32/F32
[in]src1Second input tensor info. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/QSYMM16/F16/S32/F32
[out]dstThe dst tensor info. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/QSYMM16/F16/S32/F32.
[in]policyOverflow policy.

◆ name()

const char * name ( ) const
overridevirtual

Name of the kernel.

Returns
Kernel name

Implements ICPPKernel.

Definition at line 290 of file CpuAddKernel.cpp.

291 {
292  return _name.c_str();
293 }

◆ 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.
