Abstract: The development of high-speed networks and multi-core processor has significantly increased the application complexity. In order to ensure the high throughput and real-time performance of complex application, this paper proposes a differential operation scheme for operating system tasks in multi-core environment based on BMP architecture. The cores on the processor are divided into data plane and control plane. The loop tasks with high throughput requirement are allocated to the data plane core by the operation system, and the tasks on the control plane core cannot affect the performance of data plane core. The scheme is implemented based on the Linux kernel. The experimental results show that it effectively improves the real-time response and throughput of operation system.
