摘要
提出了基于约束任务流图模型的SoC系统建模与仿真方法,并在自行开发的软硬件协同设计环境YH-PBDE中实现了SoC系统建模与仿真工具。该工具能够在算法级准确的对SoC系统行为进行描述,对SoC系统进行功能验证和初步性能分析,并很好的支持系统模型模版的复用。数字化士兵音视频解码与播放器SoC的设计实例表明:这种SoC系统建模仿真方法保证了开发正确性,缩短了开发周期,取得了良好效果。
This paper puts forward a novel SoC system modeling and simulation method based on Constrained Taskflow Graph (CTG) as SoC system model, and implements a SoC system modeling and simulating tool in YH-PBDE environment which supports SoC SW/HW co-design. The tool can describe the SoC system behavior accurately and simulate the system at arithmetic level. It can support system re-use effectively. The example of Digital Soldier Audio/Video Decoder proves that this method ensures the accuracy of development and reduces the time of up-to-market.
