Dynamic Translation (DT) is a sophisticated technique that allows the implementation of high-performance emulators and high-level-language virtual machines. In this technique, the guest code is compiled dynamically at runtime. Consequently, achieving good performance depends on several design decisions, including the shape of the regions of code being translated. Researchers and engineers explore these decisions to bring the best performance possible. However, a real DT engine is a very sophisticated piece of software, and modifying one is a hard and demanding task. Hence, we propose using simulation to evaluate the impact of design decisions on dynamic translators and present RAIn, an open-source DT simulator that facilitates the test of DT's design decisions, such as Region Formation Techniques (RFTs). RAIn outputs several statistics that support the analysis of how design decisions may affect the behavior and the performance of a real DT. We validated RAIn running a set of experiments with six well known RFTs (NET, MRET2, LEI, NETPlus, NET-R, and NETPlus-e-r) and showed that it can reproduce well-known results from the literature without the effort of implementing them on a real and complex dynamic translator engine.

“…Even though there are many optimization methods, such as hot path optimization [15], register mapping optimization [16], [17], multi-threaded parallel optimization [9] and memory access optimization [18], which can improve the efficiency of dynamic binary translation effectively, the problem of low efficiency in dynamic binary translation is still prominent. Generally speaking, DBT has drawn much attention in research and application for its good completeness and adaptability [19]. And how to solve the efficiency problem has become a hot research topic [20], [21] in the field of dynamic binary translation.…”

Binary translation technology is an effective method to solve the problem of software cross-platform transplantation, especially for software porting without source code. Static binary translation has a good translation effect in general, but it faces the problem of code discovery. Dynamic binary translation can completely reproduce the execution process of the source program according to the execution order of the binary code. But it is severely limited by its low efficiency, as the time of translation is part of the whole runtime and it is no time for better code optimization in dynamic binary translation. This paper aims to optimize the execution process of dynamic binary translation by taking full advantage of the strengths of static binary translation. An optimization method of dynamic binary translation with static pre-translation was proposed in this paper. By pre-translating the source program and using more in-depth code optimization method to optimize the translated code, most of the code translation time can be cut down and the translated code will be more efficient. A new dynamic translation framework with the static pre-translation module, based on the dynamic translator named QEMU (a quick emulator), was designed to translate the x86 program to the Sunway platform. As the experimental results show, the framework and optimization method are valid to improve the efficiency of the general dynamic translator.
