Vector Multiply-Sum Integer Modulo

vec_msum(arg1, arg2, arg3)

Each word of the result is obtained by multiplying the smaller elements in the corresponding positions of arg1 by those in arg2, adding the resulting products, then adding the corresponding word of arg3. The sum is performed with 32-bit modular addition.

Result
