基于网络监控器的专用片上网络动态容错路由
Network Monitor Based Dynamic Fault-Tolerant Routing for Application-Specific Network on Chip
摘要
Abstract
Aiming at the problem of global communication management and reliability design in application-specific Network on Chip (NoC ) ,the concept of network monitor is introduced ,which monitors overall network real-time conditions and implements path allocation algorithm .Then a novel dynamic routing scheme based on Network Monitor called DyRS-NM is presented .The pro-posed scheme has the ability to discover and deal with both congestion and permanent faults and distinguish them from transient faults .DyRS-NM can avoid transient faults by using retransmission scheme ,and also can detour congested and permanently faulted links by recalculating routing paths .The RTL-level circuits design of the network monitor and fault-tolerant router are realized ,and experimental results with a MPEG4 decoder application mapped onto network monitor based 4 × 4 mesh NoC architecture verify the system performance and cost of area and power consumption .Compared to both static XY routing and fault-aware dynamic routing FADR ,significant performance improvements can be achieved by using the DyRS-NM scheme with acceptable additional cost .关键词
