ECE519(00)  Microprocessor Microarchitecture

▣ Lecture outline
  Traditional speedup curve of Amdahl's law no longer applies to computer system performance. All the recent high-performance designs of Intel, IBM, and Sun rely on multi-core technology. This technical shift from ILP (instruction-level parallelism) to TLP (thread-level parallelism) will reshape the design of future microprocessors. In this course, we will cover both ILP and TLP techniques. The topics we cover include adaptive dynamic branch prediction, high-bandwidth instruction fetch, dynamic scheduling, multiple issue, speculation, multithreading, symmetric multiprocessors, distributed shared memory multiprocessors, synchronization and consistency, and cache and memory hierarchy designs.
