The Impact of Emerging Technologies on the Design of Computer Systems

The overall goal of this research is to develop processor systems that satisfy a desired set of constraints. These constraints typically require non-obvious trade-offs in performance, power consumption, cost, and reliability. The Lilja group is particularly interested in how changes in the underlying technology, such as the trend towards smaller feature sizes in very-large-scale integration circuits, affects how computer systems should be designed. Work during this period included several projects in this broad area, including: a study of the impact of soft errors on processors constructed with deep sub-micron and nanoscale devices; the development of tools and techniques to improve simulation efficiency and dynamic performance optimization; the development of techniques for automatically classifying the benchmark programs used to evaluate the performance of computer systems; methodologies for verifying the correctness of a microprocessor design; techniques to statistically evaluate large design spaces; and studying how spintronics components might be used to design computer systems.
