摘　　要：针对基于SystemC的可重构专用处理器模拟器在整个系统的仿真时(包括操作系统、驱动、API及应用程序)耗时久、影响开发进度的问题,提出一种基于QEMU的模拟器设计方法。根据可重构专用处理器的功能特点和系统架构,对可重构专用处理器进行抽象,利用在仿真速度上优势明显的QEMU,设计并实现一个在功能和内部存储上精确的模拟器。实验测试结果表明,该模拟器提高了全系统仿真时的速度,在硬件开发板尚未就位前,为软件开发人员提供了一个可以进行软件开发和测试的平台,提高了开发效率。A QEMU-based emulator for reconfigurable application specific processor was proposed to deal with the severe timeconsuming problem exists in the process of emulating the whole system of SystemC-based emulator encounters,including operating system,device drivers,application interfaces and software applications.Compared with SystemC,QEMU outperformed obviously in emulation speed,which provided chances to solve the problem above.By taking advantage of QEMU and abstracting functionality and architecture from the processor,the emulator designed and implemented performed with high accuracy on behavior and storage.In test,it shows great improvement on the speed of the full system emulation.And it also provides a platform for the software developers to develop and test their programs before the hardware development board being in place.
