Research on the Methods of Platform-Based SoC System Modeling

面向基于平台的SoC设计方法,本文提出约束任务流图模型(CTG)作为SoC系统模型,提出了基于平台的CTG SoC系统建模方法,实现了SoC系统建模环境CPSME.CTG模型是一种可变粒度的SoC系统模型,可同时描述系统任务的功能和性能.本文基于平台的CTG SoC系统建模方法支持CTG模型的系统级重用与定制,有效提高了系统建模效率.在CPSME环境下进行MP3播放器和MPEG2播放器的SoC系统建模实践表明,新方法的模型重用率可达到75%～90%.

Faced to platform-based SoC design, we put forward a constrained taskflow graph （CTG） as the SoC system model Based on CTG, we give a novel SoC system modeling method and implement the system modeling environment CPSME. CTG is a granularity variable SoC system model;it describes both functionality and performance constraints for tasks. Our platform-based CTG SoC system modeling method improves the efficiency of SoC modeling by supporting the CTG system level reuse and customization. In CPSME, we have conducted the SoC system modeling for MP3 and MPEG2 players. Rresults show that the new method attains an excellent model reuse rate of 75%～90%.
