void riscv_accumulate_f64(const float64_t *pSrc, uint32_t blockSize, float64_t *pResult)

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
