ECE 3056: Architecture, Concurrency, and Energy in Computation

ECE 3056: Architecture, Concurrency, and Energy in Computation

Prerequisites: 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. In particular the course addresses some basic microarchitecture support for operating systems. This is expanded into a study essential mechanisms of process generation, concurrency, and high level coverage of the OS management of the I/O subsystem and network stacks.
