Member Function Documentation

◆ Allocate()

virtual void Allocate ( )
inlineoverridevirtual

Indicate to the memory manager that this resource is no longer active.

This is used to compute overlapping lifetimes of resources.

Implements ITensorHandle.

Definition at line 284 of file NeonTensorHandle.hpp.

284 {}

◆ GetDataType()

virtual arm_compute::DataType GetDataType ( ) const
inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 289 of file NeonTensorHandle.hpp.

290  {
291  return m_Tensor.info()->data_type();
292  }

◆ GetParent()

virtual ITensorHandle* GetParent ( ) const
inlineoverridevirtual

Get the parent tensor if this is a subtensor.

Returns
a pointer to the parent tensor. Otherwise nullptr if not a subtensor.

Implements ITensorHandle.

Definition at line 287 of file NeonTensorHandle.hpp.

287 { return parentHandle; }

◆ GetShape()

TensorShape GetShape ( ) const
inlineoverridevirtual

Get the number of elements for each dimension ordered from slowest iterating dimension to fastest iterating dimension.

Returns
a TensorShape filled with the number of elements for each dimension.

Implements ITensorHandle.

Definition at line 307 of file NeonTensorHandle.hpp.

308  {
309  return armcomputetensorutils::GetShape(m_Tensor.info()->tensor_shape());
310  }

◆ GetStrides()

TensorShape GetStrides ( ) const
inlineoverridevirtual

Get the strides for each dimension ordered from largest to smallest where the smallest value is the same as the size of a single element in the tensor.

Returns
a TensorShape filled with the strides for each dimension

Implements ITensorHandle.

Definition at line 302 of file NeonTensorHandle.hpp.

303  {
304  return armcomputetensorutils::GetStrides(m_Tensor.info()->strides_in_bytes());
305  }

◆ GetTensor() [1/2]

arm_compute::ITensor& GetTensor ( )
inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 281 of file NeonTensorHandle.hpp.

281 { return m_Tensor; }

◆ GetTensor() [2/2]

arm_compute::ITensor const& GetTensor ( ) const
inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 282 of file NeonTensorHandle.hpp.

282 { return m_Tensor; }

◆ Manage()

virtual void Manage ( )
inlineoverridevirtual

Indicate to the memory manager that this resource is active.

This is used to compute overlapping lifetimes of resources.

Implements ITensorHandle.

Definition at line 285 of file NeonTensorHandle.hpp.

285 {}

◆ Map()

virtual const void* Map ( bool  blocking) const
inlineoverridevirtual

Map the tensor data for access.

Parameters
blockinghint to block the calling thread until all other accesses are complete. (backend dependent)
Returns
pointer to the first element of the mapped data.

Implements ITensorHandle.

Definition at line 296 of file NeonTensorHandle.hpp.

297  {
298  return static_cast<const void*>(m_Tensor.buffer() + m_Tensor.info()->offset_first_element_in_bytes());
299  }

◆ SetMemoryGroup()

virtual void SetMemoryGroup ( const std::shared_ptr< arm_compute::IMemoryGroup > &  )
inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 294 of file NeonTensorHandle.hpp.

294 {}

◆ Unmap()

virtual void Unmap ( ) const
inlineoverridevirtual
