Communication mechanism between the modules of the virtual experiment system for Microcomputer Principle and Interface Technology

The key of the virtual experiment system for Microcomputer Principle and Interface Technology, a representative of the virtual programmable experiment systems, is to solve the problem of dynamic interaction between the experimental programs and the virtual devices, and it demands high real-time performance. According to the functional needs of the virtual experiment system for Microcomputer Principle and Interface Technology, different modules need different languages or techniques, so it is urgent to realize the real-time communication between different modules. Based on specific circumstances, combined with several common mechanisms of process communication, the instruction and data transfer between the different modules of the system is studied and realized, and the functionality and performance requirements of the system are satisfied.
