Week 1 Sept 7    


Topics: Introduction, Python, Idle, Piazza, Moodle submission Lab/Hw Reading
  • Reading
    • Chapter 1 in the Art of Assembly.
    • Also Chapter 3, Sections 0 to 3.1.2.
    • Sections 1.3.1, 1.3.2, 1.3.3, 1.3.4, and 1.3.5 in Carter's PC Assembly Language. Note, Carter uses 1A92h to represent a hexadecimal number. I prefer 0x1A92.




 

Week 2 Sept. 14    


Topics: Processor and Memory, working with the shell, and emacs. Lab/Hw Reading
  • Monday:
RichardTuttle.png
  • Review PC destruction lab. Main players: Processor, cores, RAM, motherboard, crystal
  • How would Richard Tuttle see a computer motherboard? This is some of his artwork.
  • First diagram of a computer as seen by an assembly language programmer
  • Review Hello World program with this new knowledge

Notice how the main character uses all kinds of software packages to solve his problem. It includes working in a shell, using shell commands, and mixing the results with various programming techniques.
  • Wednesday
  • ls, cd, pwd, mkdir, rm, rmdir, cp
  • history, !, !!, alias, w, ps, who am i
  • grep, wc, head, tail
  • Redirection
  • Pipes
  • Emacs
  • quick overview (see this page)
  • set of commands
  • Lab
  • Homework




 

Week 3 Sept. 21    


Topics: Number Systems, the MOV instruction Lab/Hw Reading
  • Monday:
Crystal.jpg
ProcessorSpeedOverYears.jpg
  • Let's talk about the crystal
  • Relationship with instructions
  • Power-law for increase in processor speed
  • Ray Kurzweil on Power Laws (go to marker 3:30 min in video)
  • Playing a game of numbers
  • Hexadecimal system:
for i in range( 256 ): 
     print( i, format( i, '02X' ) )
  • Assembly:
  • Review nasm, ld
  • Understanding how data fits in memory: printing strings defined by db
  • Size of a program: data + code
  
   size helloWorld2
   text	   data	    bss	    dec	    hex	filename
     34	     14	      0	     48	     30	helloWorld2

  • Listing of the assembly and its code:
 
   nasm -f elf -l helloWorld2.lst helloWorld2.asm
   ls 
   ...
   helloWorld2.lst 
   ...
  • Wednesday
   hexdump -v -C helloWorld2
 
   00000000  7f 45 4c 46 01 01 01 00 ...
   ...
   000002b0  74 61 00 5f 65 6e 64 00    |ta._end.|
   000002b8
Observe the output of hexdump command




 

Week 4 Sept. 28    


Topics: The Mov instruction. Arithmetic instructions. Addressing Modes. Lab/Hw Reading
  • Monday:
  • Wednesday




 

Week 5 Oct 5    


Topics: Lab/Hw Reading
  • Monday:
Pentium.gif
MultiCore.jpg
  • Arithmetic instructions: ADD, SUB, INC, DEC. Skip MUL and DIV for right now.
  • A quick introduction to calling functions: CALL and RET
  • Printing decimal numbers in assembly
  • A first look at what is behind code like this:
int a;
int b;
int c;

a = 3;
b = 5;
c = a + b;

int a;
int b;
int c;
int d;

a = 3;
b = 5;
c = a*2 + b;
d = (a + b + 10 + 2*c ) * 2 - 20;
  • Exercise 2: translate the following code in assembly. If you need to refresh your memory on Java types, check this document out:
int a = 3, b = 5, c;
short d = 10, e = 0xff, f = 0;

c = ( a * 2  + b ) * 3;
f = d + (e-1);
c = a * 2* d;
  • Wednesday
  • Mountain Day?




 

Week 6 Oct. 12    


Topics: call/ret, looping, mul/div Lab/Hw Reading
  • Monday: Fall Break
  • Wednesday
  • Back to call and ret instructions: defining and using functions.
  • Exercise 1: Create a function that adds two int variables together
  • Exercise 2: Add a function that prints the two variables and their sum
  • mul and div: multi-register instructions. EDX:EAX used as default registers.
  • Exercise 3: Write a Teller-Machine program
  • The loop instruction: ECX is the counter
  • Program 1: function computes sum of 2 ints
  • Program 2: compute sum of 2 ints and print sum




 

Week 7 Oct 19    


Topics: Lab/Hw Reading
  • Monday:
  • Exercise 1: Write a Teller-Machine program
  • The loop instruction: ECX is the counter
  • Exercise 2: Compute the sum of all ints between 1 and n. (There are many possible answers)
  • Exercise 4: What is the largest amount of looping we can do with the loop instructions?
  • Exercise 5: How long does it take a loop to accumulate the sum of all the ints between 1 and 1,000,000? Any particular issues one should be worried about?
  • Program 3: Teller machine program.
  • Program 4: Teller machine with function.
