Function Usage

Sets the maximum value of the ClipReLU operation after the real-time quantization during DataCopy (CO1 -> GM).

ClipReLU is calculated as follows: min (clipReluMaxVal, srcData). clipReluMaxVal is the maximum value set by calling this API, and srcData is the source data.

Prototype

__aicore__ inline void SetFixPipeClipRelu(uint64_t config)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
config	Input	clipReluMaxVal, which is the maximum value of the ClipReLU operation. clipReluMaxVal occupies only 0 to 15 bits. It must be greater than 0 and cannot be INF or NAN.

Restrictions

When ReLU is enabled, the ReLU operation is performed before the ClipReLU operation.

Returns

None

Examples

For details about the complete example, see Complete Example.

uint64_t clipReluMaxVal = 0x3c00;
SetFixPipeClipRelu(clipReluMaxVal); // When ReLU is enabled, the ReLU operation is performed first, then clipping. clipReluMaxVal is the maximum value set through this API.
