根据闪存的独特物理特性, 提出了子页感知的闪存页面置换算法. 该算法引入了子页技术和基于相似概率的部分更新机制, 既可以提高闪存存储系统的性能, 又可计算每个内存页的置换值, 并选择了置换值最小的内存页为牺牲页. 实验结果表明, 新算法在页面命中率、 读/写操作次数、 运行时间方面均具有优势.
根據閃存的獨特物理特性, 提齣瞭子頁感知的閃存頁麵置換算法. 該算法引入瞭子頁技術和基于相似概率的部分更新機製, 既可以提高閃存存儲繫統的性能, 又可計算每箇內存頁的置換值, 併選擇瞭置換值最小的內存頁為犧牲頁. 實驗結果錶明, 新算法在頁麵命中率、 讀/寫操作次數、 運行時間方麵均具有優勢.

Due to distinctive physical characteristics, this paper proposes a subpaging aware page re-placement algorithm for flash memory. The proposed algorithm introduces a subpaging technology and a partial update scheme based on similar probability in order to improve the performance for flash memory storage sys-tem. At the same time, the proposed algorithm calculates the replacing value of each main memory page and selects the one with the least replacing value as the eviction page. Experimental results show that the proposed subpaging aware page replacement algorithm is better than current page replacement algorithms on page hit ra-tio, the number of write/read operations and runtime.
