Nowadays, more and more portable devices have been applied in our life, and the functionality of such devices have continuously increased. This will result in the bigger-size storage needed. In order to extend portable devices’ battery working time, we have observed the embedded system memory access pattern and find that not only one access pattern type could be used in a system. Therefore, we proposed a hybrid cache replacement approach combining LRU (least recently used) and LFU (least frequently used) policies in a memory system. This hybrid cache replacement policy can hold both the most recently used page and the most frequently used page in the memory system.
