Question

Suppose Pep/9 contains the following four hexadecimal

A: 19AC
X: FE20

Mem(0A3F]: FF00
Mem[0A41]: 103D

If it has these values before each of the following statements executes what are the four hexadecimal values after each statement executes?

(a) CIOA3F
(b) D10A3F
(c) D90A41
(d) F10A41
(e) E90A3F
(f) 790A41

Answer 1

The four hexadecimal values after each statement executes are provided based on the information given.

Step-by-step explanation:

Before executing each statement, let's analyze the given information:

1. Before statement (a) CIOA3F executes:
2. Mem[0A3F] = FF00
3. 
   
4. 
   
5. Before statement (b) D10A3F executes:
6. Mem[0A3F] = FF00
7. 
   
8. 
   
9. Before statement (c) D90A41 executes:
10. Mem[0A3F] = FF00
11. 
    
12. 
    
13. Before statement (d) F10A41 executes:
14. Mem[0A41] = 103D
15. 
    
16. 
    
17. Before statement (e) E90A3F executes:
18. Mem[0A3F] = FF00
19. 
    
20. 
    
21. Before statement (f) 790A41 executes:
22. Mem[0A41] = 103D

So, the four hexadecimal values after each statement executes:

• (a) CIOA3F: Mem[0A3F] = FF00
• 
  
• 
  
• (b) D10A3F: Mem[0A3F] = FF00
• 
  
• 
  
• (c) D90A41: Mem[0A3F] = FF00
• 
  
• 
  
• (d) F10A41: Mem[0A41] = 103D
• 
  
• 
  
• (e) E90A3F: Mem[0A3F] = FF00
• 
  
• 
  
• (f) 790A41: Mem[0A41] = 103D
