Question 7: [25 marks, moderate and time consuming] Using D-FFs, design a 2-bit register (B, A] with two input controls x, y and a single output F. Control (inputs) xy The behaviour of the circuit F A single shift of the values in BA to the right. O enters B. e.g., 11 → 01 → 00 01 Increment BA. If 11, then 00. Turn on if the BA is even. 10 Decrement BA. If 00, then 11. 11 A single shift of the values in BA to the left. O enters A. e.g., 00 + 10 + 11 00 a. [5 marks] Draw the state (transition) diagram b. [5 marks] Derive the state table c. [15 marks] Draw the minimized logic diagram of the circuit Question 8: [5 marks, easy but tricky] How many clocks are needed to store a 64-bit number in a system with a 30-bit data bus and 20-bit address bus?
