In order to reduce the response time and improve the throughput of the system and meet the requirements of automatic code generation, a real-time workshop (RTW) class embedded code automatic generation system based on SprintBoot framework is proposed. First, the overall structure of the automatic code generation system is designed with the support of spring boot framework. Secondly, the task module library according to the function of the system, interrupt module library, resource module library, alarm module library, event module library, and other module library is designed. Finally, the object code is generated by compiling the source program according to the structure diagram of the compiler. The experimental results show that the system can shorten the response time of the automatic code generation system, the longest response time is not more than 3 s, and it has higher throughput and concurrent users, which can better meet the requirements of RTW class embedded code automatic generation.
