group Max

Computes the maximum value of an array of data. The function returns both the maximum value and its position within the array. There are separate functions for floating-point, Q31, Q15, and Q7 data types.

Functions

void riscv_max_f32(const float32_t *pSrc, uint32_t blockSize, float32_t *pResult, uint32_t *pIndex)
