Vector Multiply
Purpose:
Multiply packed single-precision (32-bit) floating-point elements in a and b, and store the results in output.
Result:
A 128-bit vector of 4 x 32-bit single-precision floating-point that hold the result of the multiplication.
Example:
#include <xmmintrin.h>
#include <stdio.h>
int main() {
__m128 a = _mm_setr_ps(1.0f, 2.0f, 3.0f, 4.0f);
__m128 b = _mm_setr_ps(4.0f, 3.0f, 2.0f, 1.0f);
__m128 result = _mm_mul_ps(a, b);
float* res = (float*)&result;
for(int i = 0; i < 4; i++) {
printf("%f ", res[i]);
}
return 0;

Assembly Instruction:
mulps
Usage:
__m128 output =
_mm_mul_ps(
__m128 a, __m128 b
)
