(1) Steps to implement a soft PLC virtual machine on the μ Clinux platform
Translate the instructions of the ladder diagram into macro assembly and establish a macro library;
Compile the ladder diagram program written by the user into a PLM file in intermediate code form;
Convert PLM files into assembly programs;
Using an assembler to assemble a successful assembly program, convert the interpreted internal instructions (PLM files) into a program, assemble them into machine code for execution, and implement a PLC instruction machine code execution scheme, greatly improving execution speed and saving memory space;
Porting the machine code corresponding to PLC instructions to the embedded operating system for execution.
(2) The two major modules of the operating system
The operating system mainly consists of two modules: 1) conversion from ladder diagram to machine code program; 2) Execute the machine code file. The functions of each module are as follows:
1) The conversion from ladder diagram to machine code program. Firstly, compile the ladder diagram program written by the user into an intermediate code PLM file, then convert the PLM file into an assembly program, and finally use an assembler to assemble the successfully transformed assembly program, generating machine code and generating an executable PLE file.
2) Execute the machine code file. Embed the PLE file into the configured execution environment and execute it, and monitor the correctness of the program through the panel indicator light on the industrial computer.
(3) Virtual Machine Overall Design
Based on the principle and execution mechanism of virtual machines, the overall design of the machine code execution scheme for virtual machines has been carried out, as shown in Figure 3. PLC file is the saved file of ladder program. PLM file is generated by lexical analysis, syntax analysis and semantic analysis and compilation of PLC file, then macro assembly library is called, and a series of conversions are carried out to generate machine code to generate PLE file; Finally, create a machine runtime environment to execute machine code, and the macro assembly library contains the macro assembly segments corresponding to each ladder instruction.

The latest embedded design provides a large number of complex new products and services for various industries and applications. Due to cost constraints and expectations for improved performance, embedded design is providing smaller and more cost-effective solutions for various daily applications, including household appliances, tools, buildings, clothing, and almost all items around us.
These embedded designs typically consist of a microcontroller and various secondary interfaces, such as power supplies. Being able to confidently and quickly select power components is crucial for providing reliable, smaller, and more cost-effective solutions. To achieve this goal, you need to use intuitive testing and measurement tools to quickly obtain optimization results. So Beijing Oriental Zhongke Integrated Technology Co., Ltd. has compiled this solution through years of communication and self summary with customers, for reference only. This article focuses on the practical application of power analysis, using specific measurement techniques to more efficiently select and determine corresponding components for embedded design.
