vcgtq_f32ADD TO COMPARE ADDED TO COMPARE
Arm 64-bit (64 bits)/ NEON
View official documentation
Purpose:
Compare signed Greater than (vector). This instruction compares each vector element in the first source SIMD&FP register with the corresponding vector element in the second source SIMD&FP register and if the first signed integer value is greater than the second signed integer value sets every bit of the corresponding vector element in the destination SIMD&FP register to one, otherwise sets every bit of the corresponding vector element in the destination SIMD&FP register to zero.
Result:
uint32x4_t
Example:
#include <stdio.h>
#include <arm_neon.h>
int main() {
float32_t a_arr[4] = {
1.0f, 2.0f, 3.0f, 4.0f
};
float32_t b_arr[4] = {
2.0f, 2.0f, 2.0f, 2.0f
};
float32x4_t a = vld1q_f32(a_arr);
float32x4_t b = vld1q_f32(b_arr);
uint32x4_t result = vcgtq_f32(a, b);
uint32_t res_arr[4];
vst1q_u32(res_arr, result);
printf("Comparison results:\n");
for (int i = 0; i < 4; i++) {
printf("%u\n", res_arr[i]);
}
return 0;
