摘要

为了同时受益于规则拓扑和部分自定义结构，我们采用了应用指定的链路移除策略，以最大限度地减少NoC(片上网络)的面积消耗，同时具有部分规则扭曲和保证性能。我们针对单一应用的链路去除主要包括基于低链路利用率的拓扑优化迭代链路去除选择算法和基于回合模型的无死锁路由算法，用于链路减少的不规则二维网格。此外，我们还从实际需求出发考虑多应用，并尝试定义各种执行模式。通过移除链路集的相应互操作，实现了多应用与链路移除方法的无缝结合。以典型的媒体应用VOPD和MWD为例，仿真结果验证了所提出的多应用指定NoC链路去除策略对区域成本优化和可接受的性能降低是有效的。

Multi-application Specified Link Removal Strategy for Network on Chip

To benefit of both regular topology and partially customized structure, we adopt application specified link removal strategy to minimize NoC (Network on Chip) area consumption with partial regularity twist and guaranteed performance. Our link removal for single application mainly includes iterative link removal selection algorithm based on low link utilization for topology optimization and turn model based deadlock free routing algorithm for irregular 2D Mesh with reduced links. In addition, we also consider multiapplication from realistic requirement and try to define various execution modes. The seamless combination of multiapplications and link removal method is achieved via corresponding interoperation of removed link set. Taking typical media applications VOPD and MWD for example, the simulation results verify proposed multi-application specified NoC link removal strategy valid for area cost optimization and acceptable performance degradation.
