Abstract: This paper analyses the characteristics of nonperiodic tasks in Real-Time systems. The distribution function and mathematics mean of nonperiodic tasks are demonstrated, and a scheduling algorithm of nonperiodic tasks is proposed.The goal of the scheduling algorithm is to satisfy the deadline of nonperiodic tasks as possible
