Problems solved by technology

Because the Unicorn translation engine itself is based on the Qemu2.0 version, and the developer has not updated it for a long time, the design idea has fallen behind, the overall execution performance is not high, there are many bugs, and the actual effect is not good in the process of use
At the same time, Unicorn's memory management mechanism uses a set of simulated physical CPU memory memory access mechanisms to manage the address space of GVA. Every time an instruction or data is fetched, it is necessary to convert GVA into HVA through SoftMMU and obtain instruction data from HVA. , this mechanism is complex and inefficient

Embodiment Construction

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0023] Based on the rich application programs in the current X86 architecture, in order to facilitate the porting of these application software to other architectures to run, an analog processor Qemu, which is widely used in the Linux system platform, appeared, which implements CPU operations through software. Qemu There are two modes, user mode and system mode. Among them, user mode can provide simulation execution of heter...

Abstract

The invention discloses a heterogeneous program execution method, which is suitable for execution in a simulator, the simulator is suitable for resident in a computing device, and a target heterogeneous program is installed on the simulator. The method includes: when the simulator is started, Obtain the target heterogeneous program on the simulator; load the target heterogeneous program into the memory address space of the simulator process; create a virtual CPU according to the start request of the target heterogeneous program; execute the target heterogeneous program through the virtual CPU. The present invention also discloses a corresponding apparatus, a computing device and a readable storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a heterogeneous program execution method, apparatus, computing device and readable storage medium. Background technique [0002] Application software has become an important tool for people to use computers to achieve various life and work needs. The software resources are very rich. However, most of the software resources are currently implemented based on the X86 architecture, while for other architecture platforms (eg: ARM, PowerPC) , the software manufacturer does not provide versions for other platforms, and the software resources are not perfect. Although the application software achieves compatibility between different operating system platforms through wine, for example, WeChat, QQ and other common software only provide the Windows version under X86. With the Windows compatibility layer provided by wine, it can be used on the X86 Linux system. These progra...
