vadd_u8ADD TO COMPARE ADDED TO COMPARE
Arm 64-bit (64 bits)/ NEON
View official documentation
Purpose:
Floating-point Add (vector). This instruction adds corresponding vector elements in the two source SIMD&FP registers, writes the result into a vector, and writes the vector to the destination SIMD&FP register. All the values in this instruction are floating-point values.
Result:
uint8x8_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
uint8x8_t a = {
1, 2, 3, 4, 5, 6, 7, 8
};
uint8x8_t b = {
8, 7, 6, 5, 4, 3, 2, 1
};
uint8x8_t result = vadd_u8(a, b);
uint8_t res[8];
vst1_u8(res, result);
for (int i = 0; i < 8; i++) {
printf("%u ", res[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
ADD
Usage:
uint8x8_t result =
vadd_u8(
uint8x8_t a, uint8x8_t b
)
