中文摘要：
片上网络（NoC）是解决传统基于总线的片上系统（SoC）所面临的功耗、延迟、同步和信号完整性等挑战的有效解决方案。功耗和延迟是NoC设计中的重要约束和性能指标，在设计的各个阶段都存在着优化空间。基于蚁群优化算法，通过通信链路上并发通信事件的均匀分布来降低NoC映射阶段的功耗和延迟。仿真实验表明，与链路通信量负载均衡的方法相比，该方案能进一步在拓扑映射阶段优化功耗和延迟。
英文摘要：
NoC is an effective solution for challenges faced by the traditional bus-based SoC, such as power, delay, synchro- nization and signal integrity and so on. Power consumption and delay are important design constraints and performance metrics, and have optimizing space in all stages of design. Based on the ant colony optimization algorithm, the proposed approach reduced the power consumption and delay through the uniform distributed of the link concurrent communication events on NoC topology mapping phase. Simulation results show that solution compared to the link traffic balancing method can further optimize the power consumption and delay in topology mapping stage.
