Abstract: With the increasingly performance improvement and function expansion of embedded devices, the single operating system architecture is becoming difficult to meet the increased requirement of more and more complex applications. Therefore, a dual operating system architecture is proposed by the academic and industrial community. However, how to reasonably configure limited peripheral resources is an important problem remained to be solved by the dual operating system architecture. Based on the binding principle of peripheral interrupts and CPU cores in Huawei HiSilicon Hi3559AV100 SOC dual operating system architecture, a dynamic migration solution of peripheral resources during system operation is proposed, and experiments were carried out on an embedded device equipped with the SOC. The results show that the proposed solution has good feasibility and reliability during the operation.
