【摘要】:針對智能電視終端應用間資源競爭導致的系統(tǒng)性能下降問題,基于資源消耗預測,提出一種智能終端資源緩存算法。根據系統(tǒng)記錄的各應用程序的資源消耗統(tǒng)計數據,應用Markov模型預測下一時間段可能出現的資源瓶頸和應用的資源狀態(tài),利用應用的資源狀態(tài)動態(tài)調整應用權重,并以最小化應用切換時間為目標,將資源緩存問題轉化為多維多選擇背包問題,采用輕量級的啟發(fā)式算法求解資源緩存問題。仿真實驗結果表明,在智能終端中該算法對于資源消耗的預測精確度比其他算法提高5.4%,而應用響應時間縮短約45%。
[Abstract]:Aiming at the degradation of system performance caused by resource competition among intelligent TV terminal applications, an intelligent terminal resource cache algorithm is proposed based on resource consumption prediction. According to the resource consumption statistics of each application program recorded by the system, the Markov model is used to predict the resource bottleneck and the application resource state in the next time period, and the application weight is dynamically adjusted by the application resource state. Aiming at minimizing the application switching time, the resource cache problem is transformed into a multi-dimensional multi-selection knapsack problem, and a lightweight heuristic algorithm is used to solve the resource cache problem. Simulation results show that the prediction accuracy of the algorithm for resource consumption in intelligent terminals is 5.4 higher than that of other algorithms, while the application response time is shortened by about 45%.
