Questions for contest and review

• Give 3 addressing modes and tell what they do.
  
  
  
• What is the difference between the Mic-3 and the Mic-4?
  
  
  
• What makes an interupt routine "transparent"?
  
  
  
• Explain the difference between dyadic operations and monadic operations and what a shift is and what a rotation is with regards to binary numbers.
  
  
  
• An extra region of memory, this is allocated for storage of dynamic or very large objects, such as lists, trees, or arrays.
  
  
  
• What operation and B value would you use to change:

A =  11010011  10001011   111001101   00111100
into 11010011  00000000   000000000   00111100
Now rotate the answer right 8 bits.  Then shift it left 4 bits.

 
 What is the final answer?




 
• What would be the benefit(s) of using a two-address instruction to perform an addition operation versus using a three-address instruction?
  
  
  
• Why could we consider the former to be "destructive"?
  
  
  
• Discuss briefly the relationship between a computer's Instruction Set Architeture and a compiler. Why is it important to have an efficient compiler and what are the benefits of this? Define the term optomizing compiler.
  
  
  
• Give the Java statement that produced the following IJVM code:

|LoadW
|LoadC
|Add
|LoadJ
|Sub
|Dup
|Add
|StoreX




• Explain the difference between a shift and a rotate and include short descriptions of what sign extensions and zero fills do.
  
  
  
• What is the premise behind the idea that the "GOTO Statement [is] Considered Harmful"?
  
  
  
• What are the 7 common Instruction Types?
  
  
  
• What does opcode stand for and what is its purpose?
  
  
  
• Why is the most common memory cell size 8 bits?
  
  
  
• What two primary factors makes up a good ISA?
  
  
  
• What are the differences between procedures/functions, co-routines, traps, and interrupts?
  
  
  
• Explain what an accumulator is, and how it is used.
  
  
  
• What are the Design Critera for Instruction Formates?
  
  
  
• What bits does the control register PSW hold and why are these bits important?
  
  
  
• A=1111 0100 0111 1010   B=1001 1100 0000 1001

 
1)Shift A right 3 bits with sign extension
2)Rotate B left 5 bits
3)Compute (A AND B)NOR(A OR B)

4      ISTORE q
5      BIPUSH 0
6      ISTORE f
7      ILOAD q
8      ILOAD f
9      IF_ICMPEQ L1
10     ILOAD q
11     BIPUSH 1
12     ISUB
13     ISTORE q
14     GOTO L2
15 L1: BIPUSH 3
16     ISTORE s
17 L2:

Winner should get :

Perhaps the winning team(s) could receive a few extra credit points, or they could suggest what we do for the lab day after the exam?

I think a good prize for the winners would be extra points on the test!!

Why not give the winning a substantial amount of bonus points on the exam, while the rest of the class will have to answer a bonus question  to get the points on the test.
