This paper proposes a new three-dimensional scheduling model which can divide the tasks into harmonic tasks and non-harmonic tasks for the high demands of embedded mucticne plactorim. According to the characteristic parameters of the tasks and make the value of the rectangular area as the attribute of the execution region which is divided into executive region, interference region and free region with the characteristic of the area. By using these attributes of the different region, the tasks are allocated to different cores. Experimental results show that the proposed method is more fully optimizing the system utilization and throughput than PEDF.
