Draw the execution diagrams for the program in Problem, assuming

(a) RISC CPU with data stall given in Figure 1.

---

(b) RISC CPU with data forwarding in Figure 2.

Problem

The plus (+) indicates a more advanced problem and the asterisk (*) indicates that a solution is available on the Companion Website for the text.

*For the RISC design, draw the execution diagram for the following RISC program, and indicate any data hazards that are present:

1 MOVA R7, R6

2 SUB R8, R8, R6

3 AND R8, R8, R7
