ToDvpp
Function Usage
Transfers tensor data to the DVPP side.
- If the original memory is transferred by the user through the constructor, the memory needs to be managed and destroyed by the user.
- If the memory is allocated by calling TensorMalloc or Malloc, the original memory is automatically destroyed and does not need to be managed by users.
- When the media data processing function is used, there are restrictions on allocating memory on the DVPP side. For details, see CANN Application Development Guide (C&C++).
