5. New MS CpE Course Requirements Recommended for students who by the end of Summer 2004 completed FOUR OR LESS graduate courses towards their MS CpE degree

6. Core courses • There are TWO core courses common for all concentration • areas: • CS 571 Operating Systems – H. Aydin, S. Setia, C. Snow, project, C/C++ or Java • Pros: • Prerequisite for many other courses and projects • HLL (High Level Language) refresher • Offered regularly in Fall and Spring • ECE 548 Sequential Machine Theory – K. Hintz, R. Schneider • Pros: • Common theoretical and mathematical foundation used in all • concentrations • Offered regularly in Spring • Not a strong prerequisite for any other course; can be taken any time • during the curriculum.

7. Required courses • There are FOUR required courses separate for each • concentration area • Criteria of choice: • Logical sequence of four courses giving a strong foundation for • a study, research, and professional position in a given concentration • area. • All courses will be offered on a regular basis (at least once per year). • Substitutions should be allowed only under exceptional circumstances. • At least two courses are ECE courses taught by the • Computer Engineering faculty, the remaining two courses are • chosen from among the most related courses in the EE, CS, • and INFS programs. • Should include projects, and guarantee the required level of difficulty • needed to obtain the CpE degree.
