Abstract
The invention relates to a method for operating a Web page in a flash memory of an embedding system application device. In the method, the non-compressed Web page is directly stored in the flash memory; the application device mounts the Web page to the embedding operation system; the operation system operates a Web server, and appoints the Web page catalogue as the Web page mounting catalogue; the users access the Web page by a browser. By adopting the method for operating the Web page in the flash memory of the embedding system application device, the method is different from the prior art that the Web page file is firstly compressed and stored in the flash memory, and then decompressed in the memory, and then the Web page is operated in the memory; the method directly stores the non-compressed Web page file in the left space of the flash memory so as to fully use the left flash memory space while the flash memory is operated and the operation speed of the embedding system is not affected; the method saves the space of the memory.
Description
Technical field
The present invention relates to the embedded system application, particularly the method field of the operation for embedded system Web page specifically is meant the method for in the flash memory of embedding system application device, moving the Web page.
Background technology
Progress along with society; Development of science and technology; Multiplexing device also is with rapid changepl. never-ending changes and improvements, and the user also has higher requirement to embedded device, needs to provide the embedded device of complete function, safety, advantage such as quick, stable, easy to operate; Complete and perfect functions must need the complete administrative mechanism of a cover, little and special system abbreviates embedded system as.
More common embedded system has Linux, WinCE, VxWorks, UC/OS at present; Nucleus, all there are its relative merits in each system, and each embedded system obtained promoting with different application needs in different periods, and the Linux embedded system is exactly a good embedded system; Use operating system the widest and that increase income, WinCE, VxWorks; UC/OS, Nucleus are the embedded OSs of paying, and can obtain good technical support on stream.Accounted for market greatly in this piece market with regard to Linux in the present embedded system; The characteristics of Linux are to increase income; Freely, and exist the huge tissue of increasing income can be through the forum that increases income, or other approach be looked for solution no matter run into what problem in actual performance history; This system is that embedded system has been injected vigor, the development of embedded system is from now on gone through added heavy one.Because being in great demand of embedded device, good opportunity is provided to the development of embedded system.
In the process of Embedded System Design, the flash memory that can only select 2 multiple size is as memory device, the size as 1M, 2M, 4M, 8M, 16M.But program file generally can not exhaust flash memory, will cause the waste of flash memory like this.Such as, our program file size is 5M, so we select the flash memory of 8M, the flash memory residue of 3M is so just arranged.
In the performance history of project, we usually can run into the problem of Out of Memory.Be the waste of flash memory on one side, Yi Bian be the deficiency of internal memory.Utilize this part residue flash memory so try every possible means.
In existing development and Design, flash memory is can not be used as internal memory next stored program, because the speed of flash memory is too slow, when CPU frequently reads the data in the flash memory, can cause the overlong time of CPU reading of data, forms the bottleneck of system.CPU not only can be in the fetch program data, also can do write operation, like this can be slower.So in the Embedded System Design before, all can't utilize this part remaining flash memory space.
Summary of the invention
The objective of the invention is to have overcome above-mentioned shortcoming of the prior art; Provide a kind of with the Web page stores in the flash memory remaining space; Avoid the flash memory space waste, can reach the method for in the flash memory of embedding system application device, moving the Web page of saving the memory headroom purpose simultaneously.
Usually all have the interface of a Web page as man-machine interaction in embedded system, the size of this Web page generally has hundreds of KB and does not wait to several MB.Design of the prior art all is that first other program file with the Web page and embedded system is compressed into a file together, and in the device start process, the operation boot files then can unzip to the Web page in the internal memory and go.Realize the quick calling process of the Web page with this.
In embedded system, the Web page has following three important feature:
1, the Web page only need not read and need write;
2, the reading speed of the Web page does not require too fast;
3, the Web page is deposited with the form of file.
Therefore, main thought of the present invention is, utilizes above-mentioned three characteristics, in the time of design the Web page do not compressed directly to be put on the flash memory operation Web page in flash memory.Rather than earlier being kept at flash memory after the Web pages compression, unzip to the page in the internal memory again after waiting system start-up, in internal memory, move the Web page.When Web server read the Web file through file system, file system can be supported the access of different flash types, no matter be code-shaped flash memory NOR flash memory or storage-type flash memory nand flash memory.So both save memory headroom, and can not form the bottleneck on the system speed again, also do not limited the type of flash memory.
In order to realize above-mentioned purpose; The invention provides a kind of method of in the flash memory of embedding system application device, moving the Web page; Wherein, described application apparatus comprises CPU, internal memory, flash memory and input/output module, and described CPU connects described internal memory, flash memory and input/output module respectively; The described Web page is stored in the described flash memory with unpressed document form, and described method may further comprise the steps:
(1) user starts embedding system application device;
(2) described application apparatus carries out initialization operation;
(3) described application apparatus operation embedded operating system kernel;
(4) described application apparatus will be stored in Web pagefile carry in the flash memory to embedded OS;
(5) described embedded OS moves Web server, and the Web page directory is appointed as Web pagefile mount directory;
(6) user is through the browser access Web page;
(7) described Web server reads the Web pagefile of appointment and it is returned to browser;
(8) browser display Web pagefile.
Should in flash memory, move in the method for the Web page, further comprising the steps of before in described step (1):
(0) user writes the embedded system initialization files in the flash memory of application apparatus.
Should in flash memory, move in the method for the Web page, described embedded system initialization files comprise boot files, program file and unpressed Web pagefile.The step that described application apparatus carries out initialization operation is meant that specifically CPU reads boot files and it is write to internal memory.
Should in flash memory, move in the method for the Web page, described flash memory is code-shaped flash memory or storage-type flash memory.Described embedded OS is Linux, WinCE, VxWorks, UC/OS or Nucleus.The described Web page is a human-computer interaction interface.
Adopted the method for in the flash memory of embedding system application device, moving the Web page of this invention; It is different from the prior art earlier compression Web pagefile and leaves in the flash memory; Unzip to again in the internal memory, the method for the operation Web page in internal memory, but Web pagefile uncompressed directly is stored in the remaining space of flash memory; And in flash memory the operation Web page; Thereby can under the situation that does not influence operation for embedded system speed, make full use of remaining flash memory space, to reach the purpose in save memory space.
