Function Usage

Sets the address of the LocalTensor during the elementwise operation after on-the-fly quantization is performed during the DataCopy (CO1->GM) process.

Prototype

template <typename T>
__aicore__ inline void SetFixPipeAddr(const LocalTensor<T>& eleWiseData, uint16_t c0ChStride)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Meaning
eleWiseData	Input	Number of source operands on L1 Buffer. Type: LocalTensor. Supported TPosition: A1/B1/C1. The start address must be 32-byte aligned and only the half data type is supported.
c0ChStride	Input	Stride of the C0 channel on the L1 Buffer. The unit is C0_SIZE (32 bytes). The data chunk obtained by splitting eleWiseTensor in the unit of C0 along the N direction is called the C0 channel. The interval between two C0 channels is called the C0 channel stride.

Restrictions

None

Return Value Description

None

Example

__aicore__inline void SetEleSrcPara(const LocalTensor <half>& eleWiseData, uint16_t c0ChStride)
{
    AscendC::SetFixPipeAddr(eleWiseData, c0ChStride);
}
