AndC

Performs bitwise AND between a constant and each element of a vector.

The function interface is declared as follows:

Operations on integers:
HmppResult HMPPS_AndC_8u(const uint8_t* src, uint8_t val, uint8_t* dst, int32_t len);

HmppResult HMPPS_AndC_16u(const uint16_t* src, uint16_t val, uint16_t* dst, int32_t len);

HmppResult HMPPS_AndC_32u(const uint32_t* src, uint32_t val, uint32_t* dst, int32_t len);
In-place operations on integers:
HmppResult HMPPS_AndC_8u_I(uint8_t val, uint8_t* srcDst, int32_t len);

HmppResult HMPPS_AndC_16u_I(uint16_t val, uint16_t* srcDst, int32_t len);

HmppResult HMPPS_AndC_32u_I(uint32_t val, uint32_t* srcDst, int32_t len)

Parameters

Parameter	Description	Value Range	Input/Output
src	Pointer to the source vector	The value cannot be NULL.	Input
val	Fixed value	Not limited, depending on the type	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 src1, src2, 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 10

void AndCExample(void)
{
    uint16_t src[BUFFER_SIZE_T] = {55102, 65510, 45878, 34567, 55102, 65510, 45878, 34567, 55102, 65510};
    uint16_t dst[BUFFER_SIZE_T] = {};
    uint16_t val = 32574;
    int32_t i, result;
    result = HMPPS_AndC_16u(src, val, dst, BUFFER_SIZE_T);
    if (result != HMPP_STS_NO_ERR) {
        return;
    }
    printf("result = %d \n dst =", result);
    for (i = 0; i < BUFFER_SIZE_T; i++) {
        printf(" %d ", dst[i]);
    }
}

Output:

result = 0
dst = 22334 32550 13110 1798 22334 32550 13110 1798 22334 32550
