Practical sessions and labs for Architecture course 2004

---------------------------------------------------------
1. Tirgul:
----------
- basic assembly instructions
- jump & loop instructions (for the assignment 0)
- little endian
- byte structure
- registers
- flags

2. Lab:
----------
- ASCII code
- labels definition
- two simple programs to do:
	1. get string and convert upper case to lower case and vice versa.
	2. get string and print it in hexadecimal.
- Producing a listing and using it (e.g. to determine machine code length)

3. Tirgul:
----------
- sections
- advanced instructions: shift, rotate, mul, jump, masking, branch
- work with memory
- work with strings

4. Lab:
----------
- stack
- combined program of C and assembly
- advanced usage of NASM
- program to do:
	1. take C main simple file and assembly it.
	Observe parameters pass in C, compare to material given in class.
   Write a little program that uses C main, C function and assembly function:
   C main calls to assembly function, assembly function calls to C functin etc.

5. Lab:
----------
- co-routines
  * Basic scheme - implementation and testing:
    initializing and exiting the co-routines mechanism
  * Using the co-routine mechanism to develop a rudimentary
    threads package - introduction (to be completed as
    a homework exercise).

6. Lab:
----------
- NASM macros
- debugging (using gdb)
- disassembly
- basics of self-modifying code

7. Lab:
----------
- system calls
- file control blocks (working with files in assembly language)

8. Tirgul:
----------
- ELF files: introduction (using the elfread program)
  * Structure of ELF fies
  * The sections in ELF files and their structure
  * Mapping of ELF sections to memory

9. Lab:
----------
- Modifying ELF files - introduction to linking and hacking.
  * Basic hacking: changing program printouts by modifying ELF 
    executable file
  * Hacking: breaking a password protected program
  * Basic anti-hacking techniques

10. Lab:
--------
- Basic independent position code (IPC).
- Basic combination of object code programs (2 elf files)
- Introduction to homework exercise: self sufficiency of
  combining program, using: IPC and system calls.

11. Lab: 
-----------
- self modifying code - advanced
- profiling (?)

12. Tirgul:
-----------
- pipeline

13. Tirgul:
-----------
If we would cover all the material, it will be a tirgul hazara,
 i.e. questions from previous exams, etc.
