Dual management of real-time and interactive jobs in smartphones

A dual management of real-time and interactive jobs in dual-core smartphones is presented. The proposed scheme guarantees the end-to-end QoS of real-time applications, while also provides reasonable latency for interactive applications. To this end, high performance NVRAM is adopted as storage of real-time applications, and a dual purpose CPU scheduler, in which one core is exclusively used for real-time applications, is proposed. Experiments show that the proposed scheme reduces the deadline miss ratio of real-time applications by 92%.
