Exercise 5

A RISC processor has 8 global registers and 10 register windows. Each window has 4 input registers, 8 local registers, and 4 output registers. How many total registers are in this CPU? (Hint: Remember, because of the circular nature of the windows, the output registers of the last window are shared as the input registers of the first window.)
