ECE 3056: Architecture, Concurrency, and Energy  in Computation


Fall 2012


Prerequisite: ECE 2035, ECE 2031

Course Objective:This course introduces the basic organizational principles of the major components of a processor the core, memory hierarchy, and the I/O subsystem. Students gain an understanding of the sources of performance and energy dissipation in modern processors and learn the multiple forms and levels of parallelism that have been employed to sustain performance improvements in the industry. Assignments using architecture‐level simulators enable the students to explore the operation and tradeoffs in performance and energy and reinforce the concepts learned in the class room.

Attendance: Students are responsible for all material covered in class, including changes in exam schedules announced in class. Make-up exams will be considered only if the student informs the instructor of the absence prior to the exam date, or, when prior information was not possible, immediately following the exam. Make-up exams will not be the same as the exam given in class.

Academic Honesty: Although students are encouraged strongly to work together to learn the course material, all students are expected to complete assignments and exams individually, following all instructions stated in conjunction with the exam. All conduct in this course will be governed by the Georgia Tech honor code. Additionally, it is expected that students will respect their peers and the instructor such that no one takes unfair advantage of anyone else associated with the course. Any suspected cases of academic dishonesty will be reported to the Dean of Students for further action.
