Function

Initializes tiling data in Conv3DBackpropFilter objects. Resources are divided based on the tiling parameters. For details about the tiling parameters, see Conv3DBackpropFilter Tiling API.

Prototype

__aicore__ inline void Init(const TConv3DBpFilterTiling *__restrict tiling)

Parameters

**Table 1** API parameters
Parameter	Input/Output	Description
tiling	Input	Tiling parameters of the Conv3DBackpropFilter object. For details about the Conv3DBackpropFilterTilingData structure, see TConv3DBpFilterTiling Structure. Tiling parameters can be obtained through the GetTiling API on the Host side and passed to the kernel side for use.

Returns

None

Restrictions

The Init API must be called before the Iterate, GetTensorC, and End APIs, and can be called only once. The call sequence is as follows:

Init(...);
...
Iterate(...);
GetTensorC(...);
End();

Example

const Conv3DBackpropFilterTilingData* tilingData;
//... Create a Conv3DBackpropFilter object and call the init API after initializing tilingData.
ConvBackpropApi::Conv3DBackpropFilter <inputType, weightSizeType, gradOutputType, gradWeightType > gradWeight_;
gradWeight_.Init(&(tilingData->dwTiling));
