System and method for compiling and loading programmable language

Abstract

The invention discloses a system and a method for compiling and loading a programmable language. The system for compiling and loading the programmable language comprises a compiling system and an execution system, wherein the compiling system is connected with the execution system through a communication cable; the compiling system comprises an editor, a compiler, a virtual machine and an assembler, wherein the editor is used for editing a high-level language source file and then sending the edited high-level language source file to the compiler, the compiler is used for receiving the edited source file and compiling the source file to generate a virtual command program, the virtual machine is executing the virtual command program, and the assembler is used for further compiling the virtual command program into a machine command and generating a target program; and the execution system comprises a loader and an executor, wherein the loader is used for downloading the target program through a communication cable and forming the target code through loading, and the executor is used for executing the target code. The machine command is generated after virtual command conversion is carried out on the source file, and execution is carried out, so that the system has the characteristic that the virtual command is transplantable, the virtual command can be conveniently transplanted and run on each platform, the system also reaches the running speed of the machine command, and the problem that the running efficiency of the virtual command is low is solved.

Description

technical field [0001] The invention relates to a programmable language compiling and loading system and method, which are especially suitable for various industrial programmable control applications and can effectively improve the execution efficiency of programs. Background technique [0002] The programmable logic controller (PLC) used in the traditional industrial field and the distributed processing unit in the distributed control system (DCS) can be programmed by the user through the configuration software. The user programming software compiles the high-level language source file to generate a virtual The instruction is downloaded to the controller through the communication interface, and the controller runs the configuration program by interpreting the virtual instruction. The advantage of this method is that it is highly portable and can be transplanted on different hardware platforms. The disadvantage is that the operation efficiency is not high. For the same compu...

AI Technical Summary

Problems solved by technology

The advantage of this method is that it is highly portable and can be transplanted on different hardware platforms. The disadvantage is that the operation efficiency is not high. With the same computing function, the operation of virtual instructions is at least 20 times slower than that of machine instructions.

Another compilation method is to directly compile the high-level language into the machine instructions of the target platform, and download the compiled machine instructions to the processor of the target machine to run. The advantage of this method is high execution efficiency, and the disadvantage is poor portability. , any change in the program requires recompilation of the entire project, and the dependence on the target platform is too strong, and the usability is low
