Question

Write an MSP430 assembly language program that implements the
following 2 algorithms:

2) a macro called "vdot" that calculates the "dot product" of two vectors "a" and "b",
implemented as “arrays” (following the “C” language convention), of 3
elements. the macro should receive 2 pointers to the first element of each vector and
return the result in R13.
