Function Usage

Initializes tiling data in Conv3DBackpropInput objects. Resources are divided based on the tiling parameters. For details about the tiling parameters, see Conv3DBackpropInput Tiling APIs.

Prototype

__aicore__ inline void Init(const TConv3DBackpropInputTiling *__restrict tiling)

Parameters

**Table 1** API parameters
Parameter	Input/Output	Description
tiling	Input	Tiling parameter of the Conv3DBackpropInput object. For details about the definition of the TConv3DBackpropInputTiling structure, see TConv3DBackpropInputTiling 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 calling sequence is as follows:

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

Examples

const Conv3DBackpropInputTilingData* tilingData;
//... Create a Conv3DBackpropInput object and call the init API after initializing tilingData.
ConvBackpropApi::Conv3DBackpropInput<weightDxType, inputSizeDxType, gradOutputDxType, gradInputDxType> gradInput_;
gradInput_.Init(&(tilingData->conv3DDxTiling));
