Problem 1: A central processing unit (CPU) consists of at least ten general purpose registers, a program counter, an instruction register, a memory address register, a memory data register, an arithmetic and logic unit that can perform addition, multiplication, division, and three basic logical operations connected through x number of buses where x can take value 1, 2 or 3. You will choose x by dividing you registration number by 3 if your registration number is divisible by 3, x = 3; otherwise, remainder will be equal to x. (Here x=2) (5 + 7 + 8)

1. Draw a block diagram of this processor.
2. Write complete set of control signals needed in data path.
3. List sequence of control signals required to execute ADD (R_m) R_n on this processor? The subscripts of the registers (m and n) are last two digits of your registration even if both the digits are same (e.g. Reg: No FA18-BCS -043: m = 4 and n = 3)
