Xor
Performs bitwise XOR between a vector and each element of the vector.
The function interface declaration is as follows:
- Operations on integers:
HmppResult HMPPS_Xor_8u(const uint8_t *src1, const uint8_t *src2, uint8_t *dst, int32_t len);
HmppResult HMPPS_Xor_16u(const uint16_t *src1, const uint16_t *src2, uint16_t *dst, int32_t len);
HmppResult HMPPS_Xor_32u(const uint32_t *src1, const uint32_t *src2, uint32_t *dst, int32_t len);
- In-place operations on integers:
HmppResult HMPPS_Xor_8u_I(const uint8_t *src, uint8_t *srcDst, int32_t len);
HmppResult HMPPS_Xor_16u_I(const uint16_t *src, uint16_t *srcDst, int32_t len);
HmppResult HMPPS_Xor_32u_I(const uint32_t *src, uint32_t *srcDst, int32_t len);

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 9
void XorExample()
{
uint8_t src1[BUFFER_SIZE_T] = {55, 63, 123, 145, 210, 99, 123, 145, 210};
uint8_t src2[BUFFER_SIZE_T] = {123, 145, 210, 99, 123, 145, 210, 99, 123};
uint8_t dst[BUFFER_SIZE_T] = {0};
int32_t i;
HmppResult result = HMPPS_Xor_8u(src1, src2, 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 = 76 174 169 242 169 242 169 242 169
