Course Objectives

1. Explain common numeric formats and other
   commonly used encoding schemes and choose
   appropriate formats for applications (EE10),
2. The general organization of a computer system
   and the principles upon which computers are based
   (EE10),
3. The varieties of microprocessors and
   microcontrollers currently available and how they
   differ (EE10, EE16),
4. Typical assembly language instructions and
   addressing modes (EE10),
5. How a program in a high level language is
   translated and executed (EE10),
6. The roles of an operating system and how a
   processor design can support those roles (EE10),
7. How the components of a computer are
   constructed from digital logic (EE10),
8. read data sheets and other specifications of a
   processor to determine its strengths and
   weaknesses and present this information clearly
   to others (EE2, EE11, EE12, EE15)
9. select an appropriate microprocessor for an
   application and justify that selection in terms
   of speed, functionality, and cost (EE2, EE11,
   EE16),
10. select appropriate representations for data in
    an application (EE8),
11. determine the requirements for a microprocessor
    based on a set of application requirements
