We first give an analysis of the whole system and its requests for memory management then we design and implement the memory management strategies of rtos for this chip , including the paged virtual memory management mechanism without swap , the memory protection , the memory sharing and the static / dynamic memory allocation mechanism . chapter 4 describes the simulation method of the memory management strategies implemented in the previous chapter , then we analyse the results of the simulation 首先對系統(tǒng)進行了分析,得到其對操作系統(tǒng)的存儲管理的具體要求,然后針對上面提出的需求,設計并實現(xiàn)了相應的存儲管理策略,包括分頁不交換的虛擬存儲機制、存儲保護、存儲共享以及內存的靜態(tài)動態(tài)分配機制,最后介紹了在本系統(tǒng)研究和實現(xiàn)過程中用到的幾個工具軟件。
