Detailed Description

Classes
class	cv::cann::AscendEvent
	AscendEvent to synchronize between different streams. More...
struct	cv::cann::AscendEventAccessor
	Class that enables getting aclrtAscendEvent from cann::AscendEvent. More...
class	cv::cann::AscendMat
class	cv::cann::AscendStream
	In AscendCL Stream(AscendStream) is a task queue. Stream is used to manage the parallelism of tasks. The tasks inside a Stream are executed sequentially, that is, the Stream executes sequentially according to the sent tasks; the tasks in different Streams are executed in parallel. More...
struct	cv::cann::AscendStreamAccessor
	Class that enables getting aclrtAscendStream from cann::AscendStream. More...

Functions
AscendStream	cv::cann::wrapStream (size_t AscendStreamAddress)
	Bindings overload to create a Stream object from the address stored in an existing CANN Runtime API stream pointer (aclrtStream).

Function Documentation

wrapStream()

AscendStream cv::cann::wrapStream

(

size_t

AscendStreamAddress

)

#include <opencv2/cann.hpp>

Bindings overload to create a Stream object from the address stored in an existing CANN Runtime API stream pointer (aclrtStream).

Parameters

AscendStreamAddress

Memory address stored in a CANN Runtime API stream pointer (aclrtStream). The created Stream object does not perform any allocation or deallocation and simply wraps existing raw CANN Runtime API stream pointer.

Note

Overload for generation of bindings only, not exported or intended for use internally fro C++.
