Description

A method and device for adapting instructions

technical field

The present invention relates to the field of computer applications, and more specifically, to a method and device for self-adapting instructions.

Background technique

At present, with the widespread application of mobile terminals and smart phones, users' usage habits have transitioned from the era of personal computers to the era of smart phones. Smartphones with Android system are more and more widely used, and the applications are also very rich. Because the software App or games on the mobile phone are particularly exquisite and interesting, even users of Windows computers often start to pay attention to the software App or games on the mobile phone. However, since smart phones are designed to be portable and relatively compact, game users on mobile phones often wish to run software Apps or games on mobile phones on personal computers with large screens.

The existing technology generally adopts a virtual machine solution based on Virtualbox to realize an Android system virtual machine, in which mobile phone Android system applications are run. The solution is to make the Android system applications run in the virtual machine by simulating a complete mobile phone android operating environment. Android system applications generally include java code and C++ code, wherein the C++ code is compiled into a dynamic link library (.so) in the package (apk). The dynamic link library is the binary machine code of the target architecture. Compared with the intermediate code of java, the binary Machine code can be run directly to improve efficiency. However, the dynamic link library needs to provide different versions for different target platforms along with the application APK of the Android system. Currently, mobile terminals are basically dominated by the ARM-based SoC system, but there are also a certain number of x86 devices. For this reason, Intel provides a binary Interpret the component Houdini, so that applications that do not provide x86 dynamic link libraries can interpret their arm libraries as x86 instructions through binary interpretation, so that these Android system applications can also run on Intel platform mobile devices.

The existing technology establishes a sandbox architecture, but the sandbox architecture does not have the corresponding Linux kernel and basic library support, but uses Windows APIs to implement a software platform with the same function. Since Houdini is a closed source software, it does not provide a complete set of open source code for the Android system like Google. Moreover, based on efficiency and compatibility considerations, Houdini makes extensive use of Linux kernel system calls and features of the Linux operating system. However, because the Houdini component cannot be directly run into the current system, especially the use of Linux system calls and segment registers, the virtual machine simulated in exception handling cannot be fully realized or even basically impossible.

Therefore, a technology is needed to solve the problem of being able to dynamically interpret instructions when a dynamic exception occurs in a cross-system instruction call.

Monitoring unit, the startup applied in response to cross-system in the running environment of current operation system, to the cross-system application Performed initial order is monitored and determines whether performed initial order needs to carry out dynamic explanation, wherein described Running environment is used to enable to be designed to the cross-system application run in native operating system in current operation system Run in system；

Dynamic Interpretation unit, when it is determined that the initial order monitored needs to carry out dynamic explanation, according to the dynamic pre-set Interpretative rule carries out dynamic explanation to performed instruction, to generate the instruction explained by dynamic；

Static interpreter unit, using the static interpreter rule pre-set, static interpreter is carried out to the instruction explained by dynamic, So as to generate the execute instruction suitable for being run in current operation system；And

Execution unit, runs the execute instruction in current operation system, so as to ensure the normal fortune of the cross-system application OK.

7. equipment according to claim 6, in addition to initialization unit, are used to transport for setting up in current operation system The running environment of the row cross-system application, the running environment causes the cross-system is applied to be in it in primitive operation system During system operation in identical environment.

8. equipment according to claim 6, the monitoring unit determines whether performed initial order is needed into action State, which is explained, to be included：Cause exception when performed initial order is run in current operation system, then monitoring unit determines institute The initial order of monitoring needs to carry out dynamic explanation.

9. equipment according to claim 6, the monitoring unit determines whether performed initial order is needed into action State, which is explained, to be included：When performed initial order is different from the form of command adapted thereto in current operation system, then monitoring unit Determine that monitored initial order needs to carry out dynamic explanation.

10. equipment according to claim 6, the monitoring unit determines whether performed initial order is needed into action State, which is explained, to be included：When register involved in the register digit involved by performed initial order and current operation system During the difference of digit, then monitoring unit determines that monitored initial order needs to carry out dynamic explanation.
