  1. Linux is originally designed as a time - sharing operating system. due to its non - preemptive kernel, coarse time granularity, frequent disabled interrupt, virtual memory and other buffer mechanism, linux is not so “ real - time ” as rtos

    Linux的調度機制決定了它是一個分時系統，其不可搶占的內核、粗糙的時鐘粒度、頻繁的關中斷、虛存和其它緩沖機構的設置，使得linux的實時性不強。
  2. 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

    首先對系統進行了分析，得到其對操作系統的存儲管理的具體要求，然後針對上面提出的需求，設計並實現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動態分配機制，最後介紹了在本系統研究和實現過程中用到的幾個工具軟體。
  3. To improve virtual memory management mechanism, the kernel code is amended to avoid the incertitude cause by page scheduling, thus the responding speed is effectively improved. the irrationality of linux scheduling mechanism is also analyzed, and the methods and models such as to fortify scheduling occasion and adopt double kernel are also proposed to improve it

    在虛擬內存管理機制的改進上，作者從操作系統內核入手，對內核代碼進行修改，去除了由於頁面調度帶來的響應不確定性，有效的提高了系統的響應速度；在實時調度上，分析了linux現有調度機制的不合理性，提出了增加調度時機、採用雙內核等方法，給出了改進的模型。
  4. Then it works over the methods of constructing the embedded internet service system with linux which mainly include the following aspects : how to boot embedded linux system ; how to revise the linux kernel to adjust it to embedded application, especially how to revise the virtual memory mechanism ; how to mount a file system to embedded linux system ; methods of developing device drivres ; how to connect embedded linux system to internet

    然後，詳細研究分析了如何利用linux構建嵌入式internet服務系統，其中主要包括下面幾個方面的內容：如何引導嵌入式linux系統；如何修改linux內核以適應嵌入式應用的需要，這其中主要分析了對虛擬內存機制的修改；如何在嵌入式linux系統中掛接文件系統；開發硬體設備驅動程序的方法；如何將嵌入式linux系統接入internet 。
  5. When we develop the application based on the embedded linux system we must first resolve how to build the embedded linux os. during the building we must consider several problems such as how to boot linux, whether is the virtual memory mechanism necessary, how to select the file system and how to eliminate the dependment on disk

    開發基於嵌入式linux的應用必須首先解決如何構建嵌入式linux操作系統。在構建過程中通常會面臨以下幾個問題：如何引導、是否需要虛擬內存、文件系統的選擇以及如何消除嵌入式系統對磁盤的依賴。
