Abstract Taking a four-task and four-priority real time processing system as an example and by analyzing its construction process, implementation principles and software design method, a multitask real time processing system based on TMS320LF2407 MPU was designed. Combined with engineering project, the application of this multitask real time processing system in diesel engine electrical control system was illustrated. The results indicated that this system was easy to design, convenient to implement and outstanding in effect.
