2. Introduction to the Simulation Learning Platform
The “Embedded Simulation Experiment Teaching Platform” is an internationally leading embedded teaching platform based on chip instruction sets launched by Anxin Education, applicable to multiple disciplines such as computer science, software engineering, artificial intelligence, automation control, electronic science, communication engineering, and information systems.
The core function of the product is to provide 1:1 functional-level simulation of the embedded hardware experiment platform, offering soft customization of the target environment and full closed-loop code virtual execution capabilities, combined with systematic course construction and 3D scene-level experimental simulation, creating a new online experimental teaching model. The product can serve as an auxiliary/upgrade to traditional university experiments, establishing a 24-hour online virtual laboratory, and through a combination of virtual and real, providing a better experimental experience for students while reducing the teaching pressure on teachers and lowering laboratory operation and maintenance costs.
