Not

Performs bitwise NOT on each element of a vector.

The function interface declaration is as follows:

  • Operations on integers:

    HmppResult HMPPS_Not_8u(const uint8_t *src, uint8_t *dst, int32_t len);

    HmppResult HMPPS_Not_16u(const uint16_t *src, uint16_t *dst, int32_t len);

    HmppResult HMPPS_Not_32u(const uint32_t *src, uint32_t *dst, int32_t len);

  • In-place operations on integers:

    HmppResult HMPPS_Not_8u_I(uint8_t *srcDst, int32_t len);

Parameters

Parameter

Description

Value Range

Input/Output

src

Pointer to the first source vector

The value cannot be NULL.

Input

dst

Pointer to the destination vector

The value cannot be NULL.

Output

srcDst

Pointer to the source vector for in-place operations

The value cannot be NULL.

Input/Output

len

Vector length

(0, INT_MAX]

Input

Return Value

  • Success: HMPP_STS_NO_ERR
  • Failure: An error code is returned.

Error Codes

Error Code

Description

HMPP_STS_NULL_PTR_ERR

The value of src, dst, or srcDst is NULL.

HMPP_STS_SIZE_ERR

The value of len is less than or equal to 0.

Example

#define BUFFER_SIZE_T 9

void NotExample()
{
    uint8_t src[BUFFER_SIZE_T] = {198, 170, 22, 15, 13, 46, 221, 245, 156};
    uint8_t dst[BUFFER_SIZE_T] = {};
    int32_t i;

    HmppResult result = HMPPS_Not_8u(src, dst, BUFFER_SIZE_T);
    printf("result = %d \ndst = ", result);
    if (result != HMPP_STS_NO_ERR) {
        return;
    }

    for (i = 0; i < BUFFER_SIZE_T; i++) {
        printf("%d ", dst[i]);
    }
}

Output:

result = 0
dst = 57 85 233 240 242 209 34 10 99
