Understanding Computers: Core Concepts and Digital Logic

This course at the University of St. Thomas, taught by R. Smith, explores the fundamental principles that define a computer and how it operates. Students will learn about various numeric formats, microprocessors, assembly language, and high-level programming. The course objectives include understanding computer organization, digital logic, and operating systems, with practical assignments and projects focused on microprocessor analysis. By the end, students will be equipped to select and justify the use of specific microprocessors based on speed, functionality, and cost.

  4. Introductions I know who I am, who are you? R. Smith - University of St Thomas - Minnesota

  5. Course Objectives • # Explain common numeric formats and other commonly used encoding schemes and choose appropriate formats for applications (EE10), • # The general organization of a computer system and the principles upon which computers are based (EE10), • # The varieties of microprocessors and microcontrollers currently available and how they differ (EE10, EE16), • # Typical assembly language instructions and addressing modes (EE10), • # How a program in a high level language is translated and executed (EE10), • # The roles of an operating system and how a processor design can support those roles (EE10), • # How the components of a computer are constructed from digital logic (EE10), • # 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) • # select an appropriate microprocessor for an application and justify that selection in terms of speed, functionality, and cost (EE2, EE11, EE16), • # select appropriate representations for data in an application (EE8), • # determine the requirements for a microprocessor based on a set of application requirements R. Smith - University of St Thomas - Minnesota
