Abstract
In this paper, we study energy minimization consumption of a mixed criticality real-time system on uni-core. Our focus is on a new scheduling scheme to decrease the frequency level in order to conserve power. Since many systems are equipped with dynamic power and frequency level memory, power can be saved by decreasing the system frequency. In this paper, we provide new dynamic energy minimization consumption in mixed-criticality real-time systems. Recent research has been done on low-criticality mode for power reduction. Thus, the proposed scheme can reduce the energy both in high-criticality and low-criticality modes. The effectiveness of our proposed scheme in energy reduction is clearly shown through simulations results.
Highlights
Real-time systems take some inputs and produce outputs in a time-bound manner
In a real-time system, the term mixed-critically means that high-critical tasks must meet their deadlines at the cost of missing deadlines for certain low-criticality tasks
In our work we provide an efficient power-aware scheduling algorithm in MC real-time systems and adjust the optimal frequency level of high-criticality mode, to the best of our knowledge this is the first work that introduces optimal energy consumption of high-criticality mode in a mixed-criticality real-time system, the main grant our scheme is that we minimize energy in high-criticality mode dynamically and show the experimental results in simulations
Summary
Real-time systems take some inputs and produce outputs in a time-bound manner. Meeting deadline is the core concept of a real-time system such that missing a deadline may collapse the whole system.A real-time system has fragile uses such as an airline command system, which is so highly critical that a single failure can cause a major explosion. Meeting deadline is the core concept of a real-time system such that missing a deadline may collapse the whole system. A real-time system is employed in satellite receivers for collecting highly important information and failures can misguide and result in a major collapse [1]. Home appliances such as microwave, AC, electric power system, and refrigerator, etc. In a real-time system, the term mixed-critically means that high-critical tasks must meet their deadlines at the cost of missing deadlines for certain low-criticality tasks. The mission-criticality (hard real-time) failures can cause major damage in the systems such as loss of flight control, receiving wrong information via radar system, and misguiding satellite data. LO-criticality (soft real-time) is relaxed critical and can be considered less destructive such that deadlines can be violated occasionally
