摘要

片上网络成为解决片上系统互联问题的研究热点.分析了基于SystemC的片上网络软件仿真平台.以NIRGAM模拟器为例,实现了JPEG编码器和XYYX路由算法,并对三种路由算法进行了功耗与时延的对比实验,体现了其方便的扩展能力及性能评估能力.实例表明软件模拟提供了灵活的实验方式,缩短了设计和验证的周期,利于培养创新能力.%How to solve the on-chip communication bottlenecks with the embedded technology based on network-on-chip has been a hot topic. This paper analyzes the network-on-chip simulation experiment platform based on SystemC, completes three teaching experiments taking the scalable NIRGAM simulator for example, builds a JPEG encoder and a XYYX router, and makes a contrast experiment among three routing algorithms in network delay and power consumption respect. Those experiments represent the strong expansion and assessment of capability of NIRGAM simulator. The network-on-chip simulation experiment platform based on SystemC provides a flexible experimental method and cuts the time for design and verification of network-on-chip. More significantly, it is more beneficial to the development of innovation capability of students.
