| 摘 要： | 异构多核处理器体系结构可以有效减少功效开销，是处理器发展的趋势，负载不平衡问题会造成处理器执行的不稳定。提出一种基于异构感知的静态调度和动态线程迁移相结合的异构多核调度机制，解决了不同核之间的负载平衡问题，提高了吞吐量。仿真实验通过将此调度机制与静态调度策略（SS）比较，表明该机制提高了异构多核处理器的性能并保证了执行过程的稳定性。

| Abstract: | Heterogeneous multi-core architecture is becoming more and more appreciated which reduces processor power dissipation significantly while the unbalanced load problem of heterogeneous multi-core processor may cause heterogeneous multi-core processor execute instability. In this paper we propose a mechanism based on HASS (heterogeneity-aware static scheduling )and (heterogeneity-aware dynamic thread migration) HADM to ensure the load balance among various different cores. Simulation experiment shows that the mechanism improves the executing performance and ensures the stability of heterogeneous multi-core processor. |
