CMSC 313 Syllabus

Assembly Language and Computer Organization


B or better in CMSC 202

CMSC 341 recommended (additional programming experience)


This course continues the development of programming and problem-solving skills, focusing on low-level systems programming and the internal organization of the modern computer. Both the C language programming and assembly language programming are used in this course. Programming topics such compiling and linking are investigated. Unix programming tools such as emacs, gdb and makefiles are used extensively. System level topics such as CPU architecture, internal computer memory and system control flow are also covered.

Course Objectives

The student will be able to

  1. Design, impement and debug C programs.
  2. Use Unix programming tools such as gdb, make and valgrind.
  3. Interpret IA32 assembly language programs.
  4. Describe basic computer hardware components

Program Outcomes

CMSC 313 supports the CMSC program outcomes:

  • (O1) and (O3) through development of programming assignments in C in the Unix environment and analysis of assembly language programs.
  • (O5) through an examination of basic computer hardware architecture
