group BasicClip

Element-by-element clipping of a value.

The value is constrained between 2 bounds.

There are separate functions for floating-point, Q7, Q15, and Q31 data types.

Functions

void riscv_clip_f16(const float16_t *pSrc, float16_t *pDst, float16_t low, float16_t high, uint32_t numSamples)

Elementwise floating-point clipping.

Parameters

  • pSrc – [in] points to input values

  • pDst – [out] points to output clipped values

  • low – [in] lower bound

  • high – [in] higher bound

  • numSamples – [in] number of samples to clip

Returns

none
