group Accumulation

Calculates the accumulation of the input vector. Sum is defined as the addition of the elements in the vector. The underlying algorithm is used:

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

Functions

RISCV_DSP_ATTRIBUTE void riscv_accumulate_f16 (const float16_t *pSrc, uint32_t blockSize, float16_t *pResult)

accumulate value of a floating-point vector.

Sum value of a floating-point vector.

Parameters

  • pSrc – [in] points to the input vector.

  • blockSize – [in] number of samples in input vector.

  • pResult – [out] sum of values in input vector.

RISCV_DSP_ATTRIBUTE void riscv_accumulate_f32 (const float32_t *pSrc, uint32_t blockSize, float32_t *pResult)

Accumulation value of a floating-point vector.

Parameters

  • pSrc – [in] points to the input vector.
