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. Although 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 to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] Based on the rich applications in the current X86 architecture, in order to facilitate the porting of these application software to other architectures, Qemu, an analog processor widely used in Linux system platforms, 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 heterogeneous programs. However, Qemu do...

Abstract

The invention discloses a heterogeneous program execution method which is suitable for being executed in a simulator, the simulator is suitable for residing in computing equipment, a target heterogeneous program is installed on the simulator, and the method comprises the following steps: when the simulator is started, obtaining the target heterogeneous program on the simulator; loading the target heterogeneous program to a memory address space of a simulator process; creating a virtual CPU according to the starting request of the target heterogeneous program; and executing the target heterogeneous program through the virtual CPU. The invention also discloses a corresponding device, computing equipment and a readable storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a heterogeneous program execution method, device, computing equipment 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 implemented based on the X86 architecture. For other architecture platforms (for example: ARM, PowerPC) However, the software manufacturer does not provide versions for other platforms, and the software resources are not perfect. Although the application software realizes the compatibility between different operating system platforms through wine, for example, common software such as WeChat and QQ only provide the Windows version under X86, with the help of the Windows compatibility layer provided by wine, it can be sure on the X86 Linux system. ...
