The implementation of deltafile 3. 0 can be divided into two modules ? real - time file system module and manage module for both facilities and drives. the real - time file system contains four parts ? system call api layer, file node manage layer, virtual file system layer, concrete file system layer, which perform the abstraction of the facility
實時文件系統模塊包含系統調用api層、文件節點管理層、虛擬文件系統層、具體邏輯文件系統層四部分，主要完成與設備無關的數據存取介面抽象和各種文件系統標準的實現;設備與驅動管理模塊包含邏輯設備管理層、物理設備管理層、設備緩沖區高速緩存層、設備驅動管理層四部分，主要完成外部存儲設備管理及其驅動介面抽象功能。 -
First it supports the system call interfaces complied with the posix standard, which make convenience to the porting process to delta os for applications. second, delta file 3. 0 offers the entire supports to the fat logic file system format, and make it suitable in multitasks environment through technique process. once more, delta file 3. 0 support the flexible virtual file system interface and drive manage interface to make update easier
首先，其系統調用介面遵循posix規范，以便於應用向deltaos進行移植;其次， deltafile3 . 0提供了對fat全系列邏輯文件系統格式（含fat12 、 fat16 、 fat32 ）的完全支持，並通過改造將fat這種源於單任務操作系統dos的文件系統標準應用於多任務環境;此外， deltafile3 . 0提供了靈活的虛擬文件系統介面和設備驅動管理介面，便於未來的升級和擴展。 -
Deadlock prevention and surprise dismount handling during this process require heroic efforts, including a mechanism whereby a file system driver can stash a pointer to an automatic variable ( that is, one allocated on the call / return stack ) to be used in deeper layers of recursion within the same thread
在這個過程請求宏大結果的時候， （進行）死鎖預防和意外卸下處理，包括一個機制，憑借這個機制文件系統驅動可以中斷在相同線程中用於深層遞歸的自動變量的指示器（就是說，在調用/返回堆棧上分配一個） 。 -
In addition to bypassing the complexity of building a kernel to emulate and a file system image to boot into, and configuring a virtual network device for io, this shortcut also speeds up emulation, as the reams of kernel instructions that would have run to handle the system call - from the exception handler through the vfs and the device driver - are bypassed
除了繞開構建一個用於模擬的內核和一個用於啟動到其中的文件系統鏡像，以及為io配置虛擬網路設備的復雜性之外，這條捷徑還加快了模擬的速度，因為繞開了從異常處理程序到vfs再到設備驅動程序的很多內核指令，而這些內核指令本來就是用來處理系統調用的。 -
Types do not participate in the lifetime lease system. to create an instance of a server - activated type, clients either configure their application programmatically or using a configuration file and call
為了創建服務器激活的類型的實例，客戶端要麼以編程方式（或使用配置文件）配置它們的應用程序並調用new ，要麼在對activator . getobject的調用中傳遞遠程對象的配置。 -
On linux, the system call utime is used for changing the access time for a specified file
在linux中，可以使用系統調用utime （ ）來修改指定文件的訪問時間： -
The hardware design is expounded in chapter 3, which include four parts. then we focus on how to merge them together in chapter 4, that is, porting linux to mc9328mx1, this includes several parts, the first part is flashloader which can be used to download programs ; and then, give out develop model of start - up guide code ( bootloader ) which runs before linux kernel and linux kernel ' s start - up analysis, also porting them to arm9 mx1 ; thirdly, we realizes the porting of lcd framebuffer driver based on deeply grasped linux device driver model ; fourthly, the rootfs ( file system ) ? ? cramfs is designed. then we give an example that based on the embedded linux in chapter 5, what we call automobile navigation, and discuss how to develop with our arm linux to meet the need of application, too
