Operator Overloading

Overview

The AIE API provides overloading for most of the available operators.

In order to use them, you need to include a special header file and use the aie::operators namespace.

#include <aie_api/operators.hpp>
 
using namespace aie::operators;
 
aie::mask<16> less_than_add(aie::vector<int32, 16> a, aie::vector<int32, 16> b, aie::vector<int32, 16> c)
{
    return c < (a + b);
}
