Classes

class cv::cann::AscendMat::Allocator

class cv::cann::AscendEvent

AscendEvent to synchronize between different streams. 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…
