摘要: 针对片上网络通信延迟大、不能有效支持动态可重构等问题,提出一种新的片上通信模型GNLB。该模型在网络通信的基础上引入局部通信的思想,采用网络DMA通信机制,并利用网络接口对通信的控制,实现对动态可重构的控制。实验结果表明,基于GNLB构架的系统比基于总线和Mesh结构的系统在性能上分别提升了25%和14%,在硬件资源消耗上分别节省了15.87%和30.15%。

Abstract: It is hard for communication delay to meet the requirement of real time applications in Network-on-Chip(NoC), and it is difficult to add dynamic elements to the structure of NoC for dynamic reconfigurable System-on-Chip(SoC). To resolve these problems, this paper proposes an on-chip communication architecture named GNLB with the concepts of local communication. It uses network DMA, and utilities network interface that controls on-chip communication to realize effective control for dynamic reconfiguration. Experimental results show that the architecture reduces slices by more than 15.87% and 30.15%, compared to bus-based architecture and Mesh-based architecture. It saves cycles by more than 25% and 14% respectively.
