Studies computer design at the gate level. Discusses instruction set architecture design, arithmetic and logic unit design, control logic, memory design and caches, simple pipelining, I/O, and peripheral devices. Briefly covers aspects of modern computer architecture, such as multicore processors and cache coherence for these. Same as ECEN 4593. Prerequisites: Requires prerequisite courses of ECEN 2350 and ECEN 3350 (all minimum grade C-). Restricted to Electrical Engineering (EEEN), Electrical and Computer Engineering (ECEN) Computer Science (CSEN), Engineering Physics (EPEN) or Applied Mathematics (APPM).
