Application-Driven Processor Design Exploration for Power-Performance Trade-off Analysis
1 - This paper presents an efficient design exploration environment for high-end core processors. The heart of the proposed design exploration framework is a two-level simulation engine that combines detailed simulation for critical portions of the code with fast profiling for the rest. Our two-level simulation methodology relies on the inherent clustered structure of application programs and is completely general and applicable to any microarchitectural power/performance simulation engine. The proposed simulation methodology is 3-17X faster, while being sufficiently accurate (within 5%) when compared to the fully detailed simulator. The design exploration environment is able to vary different microarchitectural configurations and find the optimal one as far as energyxdelay product is concerned in a matter of minutes. The parameters that are found to affect drastically the core processor power/performance metrics are issue width, instruction window size, and pipeline depth, along with ...
