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。
NoC, which has the advantages of high bandwidth, QoS guarantee and broadcast, can provide a platform for multi-core parallel processing of communication signal system. Network coding can significantly improve NoC transmission efficiency at the expense of less power consumption. In this paper, based on the multicast characteristics and requirements of communication signal system, a suitable architecture and mapping model for Wireless NoC is established. Under multi-constraint conditions, the design meets the requirements of network throughput maximization, inter-core communication delay, data transmission and coding power consumption Such as overhead minimization of the task mapping and network coding technology joint optimization method to achieve the task of efficient parallel and multi-processing nuclear collaborative work. Experiments show that the proposed network architecture and mapping algorithm can save 6% power consumption compared with the traditional method, gain 16% throughput gain, and routing node hardware implementation complexity is low.
