A fast and generic hybrid simulation approach using C virtual machine

Instruction Set Simulators (ISSes) are important tools for cross-platform software development. The simulation speed is a major concern and many approaches have been proposed to improve the performance of ISSes. A prevalent technique is compiled simulation, which translates target programs into host instructions. But orders of magnitude of speed deterioration is inevitable since the difference between target and host Instruction Set Architectures (ISAs) can be large. An alternative is to emulate the program without sticking to binary compatibility. The performance problem is solved by using native execution. However, these emulators either require a special programming language, or a given Application Programming Interface (API). Last but not least, it is not trivial to integrate an emulator into a system simulator (which provides devices, external memory, etc., that the embedded programmers do care). In this paper, we propose a fast and generic hybrid simulation approach using virtua...
