基于网络编码的无线NoC多播映射

具有高带宽、QoS保障和广播等优点的无线片上网络（NoC）能为通信信号系统的多核并行处理提供平台，而网络编码能够以较小功耗开销为代价显著提高NoC的传输效率。本文从通信信号系统的多播特性与需求出发，为无线NoC建立合适的架构与映射模型，在多约束条件下设计满足网络吞吐率性能最大化及核间通信延时、数据传输和编码功耗等开销最小化的任务映射与网络编码技术联合优化方法，实现了任务的高效并行与多处理核的协同工作。实验表明，本文提出的网络架构及映射算法与传统方式相比能节约6%的功耗，得到16%的吞吐率增益，并且路由节点硬件实现复杂度低。 

Multicast wireless NoC mapping based on network coding

Featured by high bandwidth, QoS guarantee, and broadcasting, wireless network on chip(NoC) can provide an efficient platform for multicore and parallel processing for communication and signal processing systems. In addition, network coding can greatly increase the transmission efficiency at the cost of small power consumption in wireless NoC. On this basis, we proceeded from the features and requirements of communication and signal processing systems, and built proper architectures and mapping models for wireless NoCs. We also proposed a joint optimization method including task mapping and network coding mapping, to meet the specialized constraints and requirements of wireless NoC multicast services, such as maximizing network throughput, data transmission, and minimizing communication latency and power consumption, so as to achieve efficient task paralleling and multi-processor cooperation. Experimental results prove that the proposed architecture and mapping algorithm can achieve at least 6% power consumption saving and 16% throughput gain, with acceptable physical complexity increasement than the traditional methods.
