GetTPipePtr

Applicability

Function Usage

When a TPipe object is created, a globally unique TPipe pointer is set during object initialization. This API is called to obtain the pointer. After obtaining the pointer, you can perform TPipe-related operations.

Example

In the following example, a TPipe object is created at the entry to the kernel function. A globally unique TPipe pointer is set during object initialization. When the Init function of the KernelAdd class is called, the TPipe pointer does not need to be explicitly passed. Instead, GetTPipePtr is directly used in the function to obtain the global TPipe pointer for operations such as InitBuffer.

// inQueueX and inQueueY are TQue instances on VECIN, and outQueueZ is a TQue instance on VECOUT.
// Obtain the global TPipe pointer and use the InitBuffer API of TPipe to allocate buffers to TQue.
GetTPipePtr()->InitBuffer(inQueueX, 2, 128 * sizeof(half));
GetTPipePtr()->InitBuffer(inQueueY, 2, 128 * sizeof(half));
GetTPipePtr()->InitBuffer(outQueueZ, 2, 128 * sizeof(half));
