Add
Adds two vectors.
The function interface declaration is as follows:
- Operations on integers:
HmppResult HMPPS_Add_8u16u(const uint8_t *src1, const uint8_t *src2, uint16_t *dst, int32_t len);
HmppResult HMPPS_Add_16u(const uint16_t *src1, const uint16_t *src2, uint16_t *dst, int32_t len);
HmppResult HMPPS_Add_32u(const uint32_t *src1, const uint32_t *src2, uint32_t *dst, int32_t len);

- Operations on integers and floating-point numbers:
HmppResult HMPPS_Add_16s32f(const int16_t *src1, const int16_t *src2, float *dst, int32_t len);
- Operations on floating-point numbers:
