基于SystemC的片上网络系统级建模研究

传统的硬件描述语言不适合复杂的基于片上网络的SoC系统级建模,作为IEEE 标准的SystemC语言,比已有的HDL语言在系统级建模与软硬件协同设计方面具有优势,更适合于SoC系统级建模.文中讨论了片上网络特点,分析了SystemC适应于片上网络建模的优点,并使用SystemC构建了一个片上网络的系统级仿真模型.该片上网络采用环行拓扑,基于存储-转发的路由,由链路和路由器构成.该模型可以方便地完成对片上网络多个参数进行修改,完成性能验证.

System Level Modeling of Network-on-Chip Based on System C

The traditional HDL is not fit for system modeling of SoC(System on Chip) based on the Network-on-Chip.The IEEE 1666 SystemC standard,as a new system level language,is more suitable for system-level moceling than HDL.The paper describes the features of the network-on-chip,analyzes the adaptability of system modeling in SystemC of a network-on-chip,and constructs a system model of the network-on-chip.The network-on-chip,with a muti-ring topology and store-and-forward routing,is formed by routers connected by links.Using this system model can easily evaluate the performances by modifying the parameters of it.
