Examine characteristics of instruction set architecture and microarchitecture; physical and virtual memory; caches and cache design; interrupts and exceptions; integer and floating-point arithmetic; I/O processing; buses; pipelining, out-of-order execution, branch prediction, and other performance enhancements; design trade-offs; and case studies of commercial microprocessors. Explore behavioral-level design of a microarchitecture in a laboratory setting. Electrical and Computer Engineering 460N and Electrical Engineering 460N may not both be counted. Three lecture hours and one-and-one-half laboratory/recitation hours a week for one semester.
