A multiply/add unit takes inthree k-bit 2's complement signed numbers, x, y, and z, and produces the 2k-bitresult x y + z. Either prove that overow can occur, or that overow cannot occur during this operation.
Hint: What are the largest positive and negative values that you can generate with xy+z. Do they both t in the range of a 2k bit 2's complement integer? write the equations in terms of k forintegers x; y; z.
