GetSysWorkSpacePtr

Function Description

Obtains the pointer to the system workspace. Some high-level APIs, such as Matmul, require the system workspace. The system workspace pointer needs to be passed to related APIs. In this case, you can call GetSysWorkSpacePtr to obtain the workspace pointer. When using the system workspace, you need to allocate the workspace size on the host. The reserved space size can be obtained by calling GetLibApiWorkSpaceSize.

Function Prototype

__aicore__ inline __gm__ uint8_t* __gm__ GetSysWorkSpacePtr()

Parameters

None

Supported Models

Kirin 9020 series processors

Kirin 9030 series processors

Kirin X90 series processors

Precautions

None

Return Value

Pointer to the system workspace.

Calling Example

// ...
REGIST_MATMUL_OBJ(&pipe, GetSysWorkSpacePtr(), mm, &tiling); // Initialization
// CopyIn stage: Move data from the global memory to the local memory.
mm.SetTensorA(gm_a); // Set the left cube A.
mm.SetTensorB(gm_b); // Set the right cube B.
mm.SetBias(gm_bias); // Set the bias.
// Compute phase: Complete cube multiplication computation.
while (mm.Iterate()) {
    // CopyOut phase: Copy data from the local memory to the global memory.
    mm.GetTensorC(gm_c);
}
// End the cube multiplication operation.
mm.End();
