Function Usage

Initializes buffer and EventID for synchronizing pipeline events.

Prototype

__aicore__ inline void Init()

Constraints

This API must be used in pair with Destroy when TPipe resources are repeatedly allocated and released. If TPipe resources need to be repeatedly allocated, Destroy must be used to release the resources before Init is used.

Returns

None

Example

// Instantiate a custom operator object of the float type.
KernelInit<float> op;
uint32_t srcSize = 128;

// First execution: Use pipeIn.
AscendC::TPipe pipeIn;
pipeIn.Init(); // Initialize pipeIn resources.
op.Init(x, z, srcSize, &pipeIn);
op.Process();
pipeIn.Destroy(); // Destroy pipeIn resources.

// Second execution: Reuse the operator object but use pipeCast.
AscendC::TPipe pipeCast;
pipeCast.Init(); // Initialize pipeCast resources.
op.Init(x, z, srcSize, &pipeCast);
op.Process();
pipeCast.Destroy(); // Destroy pipeCast resources.
