Outline of Final Research Achievements

In this research project, the researcher has studied and proposed processor architecture with in-order and out-of-order execution systems. In this architecture, most instructions are executed by a simple and power efficient in-order execution system while processing the remaining instructions by a reduced high-performance out-of-order execution system. As a result, power consumption is greatly reduced while maintaining processor performance. In this research project, proposals and evaluation results on this new architecture were published in journals and symposium papers, including IEEE/ACM International Symposium on Microarchitecture (MICRO), which is the top conference in this field.
