Abstract:

为了在保持适当的仿真精度的前提下,使多处理器嵌入式系统(MPES)软硬件协同仿真的速度适合于实际应用,提出了一种基于SystemC及源代码分析器相结合的方法,即将自行开发的源代码分析器工具用于处理嵌入式软件源代码,并将其转换为标注了时间信息的ANSIC代码,通过使用BFM(busfunctionalmodel),这些代码可以被集成至SystemC系统模型中作为EPU(embeddedprocessingunit)的时间注释模型.将专用SystemC模块用于硬件建模,并对SystemC仿真内核的同步机制进行扩展以支持新的处理器中心同步仿真.时间注释模型和新的同步机制均可有效地提高仿真速度.使用这一方法成功建模仿真了一台包含12个处理器的通信设备,仿真目标设备1s内的行为耗时59.8s.试验结果表明,该方法可被用于MPES的软硬件协同设计中.
