SetBiasType

Function Usage

Sets the position, data format, data type, and transpose status of the bias matrix. These settings must be consistent with those in the kernel.

Prototype

int32_t SetBiasType(TPosition pos, CubeFormat type, DataType dataType)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
pos	Input	Position in the buffer where the bias matrix is located, which can be TPosition::GM, TPosition::TSCM, or TPosition::VECOUT.
type	Input	Data format of the bias matrix, which can be CubeFormat::ND.
dataType	Input	Data type of the bias, which can be DataType::DT_FLOAT, DataType::DT_FLOAT16, DataType::DT_BFLOAT16, or DataType::DT_INT32. The data type of the bias can be set to int32_t only when the data types of matrices A and B are both int8_t.

Returns

-1: setting failed; 0: setting succeeded.

Restrictions

None

Example

auto ascendcPlatform = platform_ascendc::PlatformAscendC(context->GetPlatformInfo());
matmul_tiling::MatmulApiTiling tiling(ascendcPlatform); 
tiling.SetBiasType(matmul_tiling::TPosition::GM, matmul_tiling::CubeFormat::ND, matmul_tiling::DataType::DT_FLOAT);  // Set the bias matrix.
