Data Structures

This chapter provides the basic data structures required for calling CANN operator APIs. Developers do not need to focus on their internal implementation and can use them directly.

Note: These basic data structures can be created through the "public interfaces" in Operator Acceleration Library, such as aclCreateTensor.

• aclTensor

  A structure defined by the framework for managing and storing tensor data (such as vectors, matrices, and other multi-dimensional data). This object can be created through the aclCreateTensor interface.

  typedef struct aclTensor aclTensor

• aclScalar

  A framework-defined structure for managing and storing scalar data (i.e., a single numeric value). The object can be created through the aclCreateScalar interface.

  typedef struct aclScalar aclScalar

• aclIntArray

  A framework-defined array structure for managing and storing integer data. The object can be created through the aclCreateIntArray interface.

  typedef struct aclIntArray aclIntArray

• aclFloatArray

  An array structure defined by the framework for managing and storing float32 data. This object can be created through the aclCreateFloatArray interface.

  typedef struct aclFloatArray aclFloatArray

• aclBoolArray

  An array structure defined by the framework for managing and storing Boolean data. This object can be created through the aclCreateBoolArray interface.

  typedef struct aclBoolArray aclBoolArray

• aclTensorList

  An array structure defined by the framework for managing and storing multiple tensor data. This object can be created through the aclCreateTensorList interface.

  typedef struct aclTensorList aclTensorList

• aclScalarList

  An array structure defined by the framework for managing and storing scalar data. This object can be created through the aclCreateScalarList interface.

  typedef struct aclScalarList aclScalarList

• aclOpExecutor

  An executor data structure defined by the framework, serving as a container for executing operator computations.

  Typically, when calling the one-stage operator interface aclxxXxxGetWorkspaceSize, the framework automatically creates an aclOpExecutor; after calling the two-stage interface aclxxXxx, the object is automatically released.

  typedef struct aclOpExecutor aclOpExecutor

• aclrtStream

  A stream processing data structure defined by the framework, used to manage and maintain the execution order of some asynchronous operations.

  typedef void *aclrtStream
