Problems solved by technology

[0006] 1. There is no guarantee of compatibility, and there is no guarantee that the J2ME software package for all JAVA games can be converted smoothly
[0007] 2. Insufficient real-time performance. Running the J2ME software package of JAVA games through this method needs to go through three stages of conversion, installation, and operation, which consumes JAVA game startup time and poor user experience
[0008] 3. Insufficient openness. The core part of this method is commercial software that is not open source, and it is impossible to modify it in time according to the platform requirements
[0009] There is no further solution to these problems in the prior art

Embodiment Construction

[0069] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0070] The JAVA virtual machine implementation method on the intelligent operating system of the present invention first divides the JAVA virtual machine software into the following two parts:

[0071] The startup entry part is responsible for graphics display, audio playback, user input processing, etc., as the startup entry of normal Android applications;

[0072] The CVM virtual machine part, CVM or C virtual machine, is the embedded version of the JAVA virtual machine. It works in the Linux user space in the form of a dynamic library, is responsible for the analysis and operation of the J2ME software package, executes the drawing and audio logic of the J2ME software package, and Process user input events according to the logic of the J2ME software package;

[0073] The startup entry part and the CVM virtual machine part communicate through JNI (JAVA NATI...

Abstract

The invention relates to a JAVA virtual machine implementation method for an intelligent operating system. JAVA virtual machine software is divided into the following two parts: a boot entry part and a CVM virtual machine part. The boot entry part and the CVM virtual machine part are in communication through a JNI, shared memory space and the like. The operating environment structure of a JAVA virtual machine is divided into two layers, namely, a Linux user layer and a Dalvik virtual machine layer, the boot entry part is operated on the Dalvik virtual machine layer, and the CVM virtual machine part is operated on the Linux user layer. According to the implementation method, the JAVA virtual machine software is installed in an Android system, the JAVA virtual machine software can be operated independently and efficiently, a J2ME software package or other J2ME programs can be explained and operated independently, complete compatibility and stability on the J2ME programs are ensured, the J2ME programs are independently started through the JAVA virtual machine and are directly operated, high real-time performance is achieved, and user experience is better.

Description

technical field [0001] The invention relates to the technical field of JAVA virtual machine and J2ME (JAVA2Micro Edition), in particular to a method for realizing a JAVA virtual machine on an intelligent operating system. In particular, it refers to the implementation method of a JAVA virtual machine that can run a J2ME software package on an intelligent operating system platform. The smart operating system platform specifically refers to Android and its derivative operating system platforms. Background technique [0002] Android is an open source intelligent operating system based on Linux, which is mainly used in portable devices, smart TVs, tablet computers, set-top boxes, etc. The Android operating system was originally developed by Andy Rubin and initially primarily supported mobile phones. In 2005, it was acquired by Google and injected capital, and formed the Open Handset Alliance to develop and improve, and gradually expanded to tablet computers and other fields. ...
