Operating system based on C language virtual machine

Abstract

The invention provides an operating system based on a C language virtual machine. The operating system based on the C language virtual machine comprises an application programming interface layer, a virtual machine layer and a global platform management layer, the application programming interface layer is used for providing a system standard library function corresponding to an application programming interface for a C language application program; the virtual machine layer is used for providing a runtime environment and a virtual machine interpreter function for a C language application program so as to realize a corresponding C language application program function; the global platform management layer is used for downloading a downloading script corresponding to a target binary file of the C language application program and instantiating and installing the C language application program. The operating system based on the C language virtual machine is higher in performance and more popular and suitable for users, the operating system supports downloading, installing and running of the C language application program, the performance requirement of the C language application program is guaranteed, and meanwhile the requirement that the C language application program can be executed in a cross-platform mode is met.

Description

technical field [0001] The invention relates to the field of smart card virtual machines, in particular to an operating system based on a C language virtual machine. Background technique [0002] At present, in the field of smart cards, in order to facilitate the porting of applications between platforms and to simplify the development of upper-layer applications, virtual machines are generally used to shield the differences in the underlying platforms. In the prior art, generally based on the smart card hardware system, an operating system based on the JavaCard virtual machine is constructed by means of software to support the download, installation and operation of Java programs. [0003] However, the existing operating system has the following problems: on the one hand, the Java virtual machine in the existing operating system is developed by a foreign company, so the existing operating system does not have domestic independent intellectual property rights; on the other h...
