View official documentation
Purpose:
Multiply (vector). This instruction multiplies corresponding elements in the vectors of the two source SIMD&FP registers, places the results in a vector, and writes the vector to the destination SIMD&FP register.
Result:
float16x4_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float16x4_t a = {
1.0, 2.0, 3.0, 4.0
};
float16x4_t b = {
4.0, 3.0, 2.0, 1.0
};
float16x4_t result = vmul_f16(a, b);
float16_t* res = (float16_t*)&result;
for(int i = 0; i < 4; i++) {
printf("%f ", (float)res[i]);
}
return 0;
}Prototypes
Assembly Instruction:
FMUL
Usage:
float16x4_t result =
vmul_f16(
float16x4_t a, float16x4_t b
)
