一种在手持信息设备上存储系统及应用程序的方法技术领域 A method for a handheld device information storage systems and applications BACKGROUND

本发明涉及文件存储技术,尤指一种在手持信息设备上存储系统及应用程序的方法。 The present invention relates to document storage technology, particularly to a method on a handheld device information storage systems and applications.

发明背景 BACKGROUND OF THE INVENTION

随着信息技术的迅猛发展,各种各样的信息设备应运而生,为了进一 With the rapid development of information technology, a variety of information equipment came into being, in order to enter a

步方便用户的使用,出现了众多诸如掌上电脑、个人数字助理(PDA)、 多功能移动电话等手持信息设备,人们可以直接通过手持信息设备,随时随地的获取信息和记录信息。 Step convenience of users, there have been numerous such as handheld computers, personal digital assistants (PDA), multi-function mobile phones and other handheld information devices, people can hand-held information devices, anytime, anywhere access to information and records information directly.

通常,手持信息设备采用半导体存储器:闪存(Flash)、动态随机存储器(DRAM)来存储系统信息、应用程序和用户数据,但在实际使用时采用的结构有所不同。 Typically, a handheld information device using a semiconductor memory: a flash memory (the Flash), dynamic random access memory (DRAM) to store system information, applications, and user data, but the structure is employed in practical use is different.

传统掌上电脑设备中Flash的存储结构如图1所示,包括存储区域】0 和存储区域11两部分,其中,存储区域10用于存放自举程序(Boot Loader), 该自举程序的主要功能是作为操作系统(OS)升级时的工具。 Traditional handheld devices Flash memory structure as shown, including a storage area and a storage area 11 0] in two parts, wherein the storage area 10 for storing the bootloader (Boot Loader), the main function of the bootstrap procedure 1 as a tool to upgrade the operating system (OS). 当设备重新复位时,系统从复位(Reset)陷阱进入自举程序,即:复位后CPU直接从这里取指令执行。 When the device is reset, the system enters a bootstrap program from a reset (Reset) traps, namely: reset the CPU fetches instructions directly executed here. 如图2所示,CPU首先判断是否需要更新OS?如杲需要, 则转入自举程序的更新OS功能,否则直接跳转到OS起始地址处。 As shown, the CPU 2 determines whether or not to update the first OS? Gao as needed, the process proceeds to update the bootstrap program OS functions, or jump directly to the start of the OS. 存储区域11则用于存储操作系统(OS)软件及应用(AP)软件,在传统的掌上电脑设备中,内置于只读存储器(ROM)的系统软件和应用软件是通过一次性编译连接成一个大的代码块,然后以二进制机器码格式连续存放于 Storage area 11 for storing an operating system (OS) and application software (AP) software, in a conventional handheld device, incorporated in a read only memory (ROM) system software and application software are connected into a one-time compiler a large block of code, and machine code binary format stored in the continuous

Flash中的,即存放于存储区域ll中。 Flash, that is stored in the storage area ll.

另外一些手持信息设备,如使用掩膜只读存储器(MaskROM)作为OS 存储器的PDA设备,由于其代码不可能更新,不需要自举程序,而直接将OS的起始代码放在CPU的复位陷阱处,如图3所示。 Other handheld information device, such as using a mask read only memory (MaskROM) PDA memory device as an OS, because it can not update the code, do not need to bootstrap program, the start code directly on the OS of the CPU reset trap at, as shown in FIG. 该PDA中的系统软件和应用软件同样是通过一次性编译连接成一个大的代码块后,以二进制格式连续存放在MaskROM中。 After the PDA system software and application software are also connected to a large code block only once compiled, it is stored in binary format MaskROM in continuous.

由于上述手持信息设备对系统及应用软件的处理都是:先编译为一个代码块,再连续存储于存储介质,如Flash中。 Since the above processing of the handheld information device system and application software are: a first block of code is compiled, and then continuously stored in a storage medium, such as Flash. 如此,使得文件注册表在编译连接时就固定了,且不可更改。 So that the registry file is fixed at compile the connection can not be changed. 如果其中某个应用程序或某个驱动程序被发现有错误(BUG)需要更新,或是某些程序需要升级时,就必须将整个系统加应用软件重新编译连接,形成新的代码块,然后还要将Flash中的内容全部擦除,重新写入。 Wherein if an application or a driver is found to have errors (BUG) needs to be updated, upgraded, or for certain programs, they must be added to the system is connected to recompile the application, the formation of new code blocks, and further To all the content in Flash erase and re-write. 这样不仅缺乏灵活性、增加操作复杂度、降低工作效率,而且该过程一般须由专业人员和专门工具才能完成,给用户的使用带来很多不便。 This is not only a lack of flexibility, increase operational complexity and reduced efficiency, but the process is generally to qualified personnel and specialized tools to complete, to the user's use in many ways.

具体实施方式 detailed description

下面结合附图及具体实施例对本发明再作进一步详细的说明。 Specific embodiments of the present disclosure will be described in further detail below in conjunction with the accompanying drawings and.

如图4所示,为了能以文件方式存储系统程序和应用程序,本发明在存放结构上,将Flash分为自举程序区40和文件存储区41两部分,自举程序区40仍然用于以二进制格式存储自举程序,而文件存储区41则预先格式化为标准的文件格式,用来以文件方式存储编译好的OS文件和每个应用程序文件。 4, in order to store system programs and application program files embodiment, the present invention is in the storage configuration, the Flash into the bootloader region 40 and the two parts of the file storage area 41, the bootstrap program area 40 is still used in the bootstrap program stored in binary format, and the file storage region 41 is preformatted as standard file formats for files stored in the OS file and the compiled file for each application. 图4中的DRAM区用于临时存放当前执行的OS文件或应用文件,比如:启动时,自举程序通过文件读取方式访问文件存储区41,将特定的OS文件拷贝到DRAM中执行;或是,当要运行某个应用程序时,OS 将该应用程序文件拷贝到DRAM中执行,以提高运行速度。 DRAM in FIG. 4 for temporary storage region OS file or a currently executed application file, such as: start, the bootstrap program read access to the file by the file storage area 41, a particular OS file copy to the DRAM performed; or It is that when you want to run an application, OS the application files are copied to the DRAM performed to improve the operating speed.

本发明在编译时就将OS程序和每个应用程序分开编译,形成不同的文件,其中特定的OS文件可定义一个特殊的名称,比如NK.bin等。 The present invention will be compiled for each application and the OS program compiled separately to form different files, wherein the specific OS may define a particular file name, such as NK.bin like. 该OS 程序可分成若干个文件单独存放,每个应用程序也可以分成若干个文件存放。 The OS program file may be divided into a number of separate storage, each application may be divided into a number of file storage. 之后,将OS文件以及应用程序文件写入文件存储区41中,由于是采用文件方式存放,代码的存放位置可以是连续的或不连续的,由文件分配表决定。 Thereafter, the OS files and application files written to the file storage area 41, since the embodiment is the use of file storage, the storage location code may be continuous or discontinuous, it is determined by the file allocation table.

所提到的文件分配表(FAT, File Allocation Table )是用来记录文件所在位置的表格,是一个记录》兹盘上头文件大小及其所对应簇的数据库,它对每一个簇都有一个相对的记录点(Entry Point)。 File allocation table (FAT, File Allocation Table) is a table referred to for the recording location of the file, a record is "hereby top disc file size and the corresponding database clusters, each cluster has a relatively record points (Entry point). 如果文件分配表丢失, 硬盘上的数据将因无法定位而不能使用。 If the file allocation table is lost, the data on the hard disk will not be due to inability to locate and use. 文件分配表的构成与所采用的文件系统有关,在实际应用中,可采用的文件系统有很多,比如:FAT16、 FAT32、 NTFS等等。 Configuration file allocation table file system used about, in practical applications, there are many file systems may be employed, such as: FAT16, FAT32, NTFS, etc. 结合手持信息设备的特点,本发明目前采用FAT16 The characteristics of the handheld information device, the present invention is currently used FAT16

文件系统,其是用16位比特的空间来表示每个扇区(Sector)配置文件的情况,该扇区就是指一块512字节的区域,FAT文件系统将数个扇区合并 File system, which is represented where each sector (Sector) profile with 16-bit space, the sector refers to a 512-byte area, the FAT file system and the combined number of sectors

成一个簇(Cluster),作为文件分配存储空间时的基本配置羊位,每个簇中 Into a cluster (the Cluster), sheep basic configuration bit allocation of storage space as a file, each cluster

的扇区数目必须是2的次方,每个文件存储于硬盘中时必须配置足够数量的簇。 The number of sectors must be a power of two, a sufficient number of clusters must configure each file is stored in the hard disk.

在本发明的文件存储方式下,当某个程序需要修改或升级时,可将与该程序相关的文件单独编译,然后象拷贝文件一样简单地以同名覆盖方式完成相应文件的更新,然后重新启动即可。 In the embodiment of the present invention, the file is stored, when the need to modify or upgrade a program, the program may be associated with a separately compiled files, and then copy the file as the same name as simply cover the finished updating the file, and then restart It can be.

本发明中还进一步提供有一个资源管理器,在资源管理器中用户看到的文件存储区显示为一个文件夹。 The present invention further provides a resource manager, the resource manager of the user to see the file storage area is displayed as a folder. 另外,该资源管理器将与os有关的系统文件隐藏,以免被用户误删。 In addition, the Explorer file system and os related hidden to avoid accidentally deleted by the user.

在本发明中,自举程序的功能发生了变化,包括三个部分:格式化Flash、 下载OS和AP文件、引导系统。 In the present invention, since the lifting function of the program changes, comprising three parts: formatting Flash, downloads the OS and AP file, boot the system. 在正常启动时,自举程序的功能就是引导系统,其实现过程是这样的:自举程序初始化系统,在文件存储区中找到OS中涉及启动的相应文件,将其拷贝到预定地址的DRAM中连续存放; 然后跳转到DRAM中OS启动文件的开始地址,执行OS启动代码;OS启动后,存放OS和AP的文件存储区相当于一个内置的石兹盘。 In normal start, since the function of the bootloader it is guidance system implementation process is as follows: bootstrap program system initialization, to locate the file OS involved started in the file storage area, copy it to a predetermined address in DRAM stored continuously; then jumps to the start address of a DRAM OS startup file, executes the OS boot code; after OS startup, OS and AP stored in the file storage area corresponding to a built-in stone hereby disc.

对于Flash中文件存储区的格式化,有两种情况: 一种是在生产时,采用专用工具,比如Ghost 6.0将Flash格式化为FAT16文件格式,并将编译好的OS和AP文件拷贝到该文件存储区中;另一种是用户可在任意时刻对其进行格式化,用于对文件存储区损坏后的重建。 For formatting the Flash file storage area, there are two cases: one is the production, using special tools, such as Ghost 6.0 Flash-in FAT16 file format, and the OS and AP compiled files are copied to the file storage area; the other is to format the user can at any time, for the reconstruction of damaged file storage area. 具体实现是:用户通过按组合功能键的方式进入自举程序界面,该界面会显示三个选项: Specific implementation is: a user interface by entering the bootstrap program by combination of function keys, the interface displays three options:

a. 拷贝文件到Flash; . A copy the files to the Flash;

b. 格式化Flash; . B Format the Flash;

c. 清除DRAM并重新启动。 c. Clear the DRAM and restart.

当选择第2项后,自举程序便会进入格式化流程:首先将Flash中的文件存储区全部擦写一次,标记出坏块;然后自动调用预先设置于自举程序启动代码中的标准格式化函数将该文件存储区格式化为标准FAT16格式。 When the second option, the program will enter the bootstrap formatting process: First, the file storage area Flash erase all the time, marking bad blocks; then automatically invoke the bootstrap startup code in the standard format set in advance in the the function of the file storage area formatted in a standard format FAT16.

本发明以文件方式存储OS和AP的方法可应用于不同的硬件环境中, 图5、图6分别给出了两种硬件应用环境。 In the present invention stores the OS and AP file method described may be applied to different hardware environments, FIG. 5, FIG. 6 are given the two hardware environments. 通常,手持信息设备采用或非(NOR) Flash或者与非(NAND ) Flash作为存储器,NOR Flash是线性寻址的,即:可以寻址到每个字节,其可以直接连接在系统的某段地址空间上,由CPU直接读出指令来执行,实现就地执行(XIP),如图5所示。 Typically, using a handheld device or information (NOR) Flash or NAND (NAND) Flash Memory as, NOR Flash linear addressing, namely: each byte to be addressed, it can be directly connected to a certain system, address space, the CPU reads the instructions directly executed, implement execution in place (the XIP), as shown in FIG. 而NAND Flash是页面寻址方式,每个存储单元不能直接映射为系统地址空间的某个单元,CPU也不能通过直接取指令的方式来读取NAND Flash中的数据,必须经过接口逻辑完成页地址转换后才能读出NAND Flash中的内容,即:CPU通过接口逻辑将NAND Flash连接到自身的系统空间上,映射为IO端口,然后通过访问设备的方式对NAND Flash操作,如图6所示, NAND Flash无法实现XIP。 And NAND Flash is a page addressing mode, each memory cell can not be mapped directly to a unit of the system address space, the CPU can not directly pass to fetch the read data in the NAND Flash, the interface logic must complete page address after converting the content read in the NAND Flash, namely: CPU via the NAND Flash interface logic to the system itself space mapped IO port, and then through the access device to the NAND Flash operation mode, shown in Figure 6, NAND Flash can not be achieved XIP. 而且,NOR Flash的成本比NAND Flash的成本高很多。 Also, NOR Flash's cost is much higher than the cost of NAND Flash.

当采用NORFlash为OS和AP的存储介质时,如图5所示,可将NOR Flash的存储空间分为两部分: 一部分是从CPU复位陷阱的地址开始约几百K的空间,用于以二进制连续存放自举程序(Boot Loader),系统复位后, CPU直接从这里取指令执行;另一部分是该NOR Flash其余的空间用于存储OS和AP,对该部分进行格式化形成文件存储区,该存储结构如图4所示。 When NORFlash OS as the storage medium and the AP, shown in Figure 5, may be a NOR Flash memory space is divided into two parts: one is about several hundreds K space beginning from the CPU to reset the trap addresses, for binary continuously storing bootloader (Boot Loader), system reset, the CPU instruction execution taken directly from here; the other is the remaining NOR Flash memory to store the OS and the AP, the portion formatted file storage area is formed, the memory structure as shown in FIG.

当采用NAND Flash作为OS和AP的存储介质时,如图6所示,该硬件环境是同时采用NOR Flash和NAND Flash作为存储器,但NOR Flash 只用于存储自举程序,如此可选用容量小的NOR Flash,从而既降低产品成本,又可保证自举程序的就地执行。 When NAND Flash storage medium as the OS and AP, as shown in FIG. 6, the hardware environment is simultaneously employed as a NOR Flash memory and NAND Flash, NOR Flash, but only for storing the bootloader, the choice of such a small volume NOR Flash, which not only reduce product costs, but also ensure that the bootstrap program execution in place. 对于OS、 AP和用户数据,可选用容量较大的NAND Flash来存储,并且在格式化时,直接将整块NAND Flash 格式化为标准的FAT16文件存储格式,OS和每个AP被分别编译为一个或多个文件单独存放。 For the OS, AP and user data, can be selected to a larger capacity NAND Flash memory, and when formatting directly block formatted as a standard NAND Flash FAT16 file storage format, OS, and compiled for each AP are respectively one or more files stored separately.

在图6所示的硬件环境下,当系统初次启动时,CPU的指针指向复位陷阱,开始执行NOR Flash中的自举程序;自举程序通过访问设备的方式将存放于NAND Flash中的OS文件拷贝到DRAM中,然后将CPU的指针指向DRAM中的OS入口,开始执行OS代码,启动OS。 In the hardware environment shown in FIG. 6, when the initial system startup, the CPU pointer to reset the trap, starts executing the bootstrap program in NOR Flash; bootstrap program by accessing the device will be stored in a manner in NAND Flash OS file copied to the DRAM, and the CPU pointer to the entry in the DRAM OS starts executing OS code, OS startup. 当要运行某个应用程序时,OS将NAND Flash中的应用程序代码拷贝到DRAM中执行。 When you want to run an application, OS NAND Flash application code will be copied to DRAM for execution.

以上所述,仅为本发明的较佳实施例而已,并非用于限定本发明的保护范围。 The above are only preferred embodiments of the present invention but are not intended to limit the scope of the present invention.
