Abstract—In this paper, a List Simulated Anneal (LSA) algorithm is proposed for the DAG tasks scheduling on the Network-on-chip to simultaneously optimize makespan, load balance and average link load. A task list is first created for the DAG tasks, and the task-to-processor assignment is performed using Best Fit rule. Then the generated schedule is further optimized using LSA. In LSA, the task execution order is determined by the task list, and the task mapping solution is optimized using simulated annealing. By conducting series of simulation, the performance of our proposal is validated. Comparing to the list Best Fit and list random mapping algorithm, our LSA has 9% and 25.4% shorter makespan, 31.1% and 79.4% better load balance and 18% smaller average link load.
