Course Description

Explores shift register devices and circuits; design, timing analysis, and application of synchronous state machine circuits using discrete devices and programmable logic devices. Includes timing analysis of asynchronous state machines, arithmetic circuits and devices; internal architecture of a microprocessor; design and interfacing of memory systems. Introduces design for test techniques. Reinforces the systematic design methodology, documentation standards, and use of computer-based tools. Prerequisites: ENGR 171. Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Realize complex logic functions utilizing programmable logic.
  2. Design machines for the purpose of manipulating data streams.
  3. Design complex digital systems.

Course Activities and Design

Course activities will include lecture presentations, coordinated homework and laboratory assignments, and examinations.

Outcome Assessment Strategies

Student evaluation includes examinations, laboratory assignments, homework assignments, and a final comprehensive examination. Specific evaluation procedures will be discussed during the first class meeting.
