| 摘要: |
| 对具有可动态独立调整运行频率/电压的多功能部件配置结构M,基于全局调度的循环依赖关系,使用ILP形式化框架,研究了对给定循环L进行动态频率/电压调整的低功耗软件流水调度的编译优化技术.提出了一种合理而有效的低功耗最优化软件流水调度方法,使其在运行时保持性能不变而消耗的功耗/能量最小. |

| Abstract: |
| Based on loop-carried dependence of global schedule, the compiler optimization technology of low power software pipeline scheduling is studied as a kind of ILP formulation for a given loop L under the configuration M with dynamic frequency/voltage scalable multi -function units. A reasonable and effective method of power-aware optimal software pipeline scheduling is proposed. It can make the loop run with minimized power/energy and without performance penalty. |
| Key words: software pipeline low power compiler optimization dynamic frequency scalable parallel processing |
