摘　　要：系统芯片面临的重大挑战在于设计之初对软硬件进行划分,并对系统的性能评估。针对这一挑战,阐述在ARM指令集模拟器基础上扩展片上总线(AMBA)模型、SDRAM控制器模型和SDRAM模型。实验结果显示,对MPEG4解码算法进行软硬件划分,采用模型可以准确地评估MPEG 4解码系统的性能和功耗。The big challenge of system chips lies in the partition of SW/HW and the evaluation of the system. Faced with it,the AMBA bus model,SDRAM controller model and SDRAM model based on ARM ISS simulator are designed. According to these models,the experiment indicates that the performance and power consumption of MPEG4 decoding system can be estimated accurately.
