Problems solved by technology

[0005] However, both of the above two solutions have their disadvantages. Method 1 has a very high transformation cost and is not conducive to market promotion; Method 2 is suitable for embedded systems that do not support remote BOOT upgrades and are distributed in quite scattered In other words, this method cannot solve the problem of system version upgrade

Embodiment Construction

[0020] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Generally speaking, the principle of the present invention is on the basis of fully analyzing the embedded system version making, version structure and loading operation process, utilizes the background host computer and the foreground embedded system to combine, realizes making the self-extracting version in the background, and in the The frontend implements self-extracting and loading methods.

[0022] Taking a single board in a 3G system composed of multiple embedded systems as an example, the flow of the self-extracting method of the embedded system version is described.

[0023] The single-board CPU adopted in the preferred embodiment of the present invention is PPC860, the size of RAM is 32MBYTE, the size of the application version storage area is limited to 2.5MBYTE, the size of the applicati...

Abstract

A self-compression method for embedding system versions includes the following steps: A. Acquire application version for version upgrade from a host computer, and make a decompression tool version for decompression and loading for the application version; B. Perform nondestructive compression for the application version on the host computer, and combine the compressed contents into a decompression tool version to form a self-compression version; C. Download the self-compression version into an application version storage region in an embedding system, and load to run the self-compression version. The invention needs neither modification to hardware, nor BOOT upgrade before effectively overcome shortcoming in version storage space capacity, and meanwhile, creates no influence to other functions of the application version; besides, the starting time of the version running becomes longer, but the version storage capacity remains the same, for which the invention is a typical method to replace space with time.

Description

technical field [0001] The invention relates to a self-decompression method of an embedded system version, in particular to a method for making a self-decompression version in the background, self-decompression and loading in the foreground by combining a background host and a foreground embedded system. Background technique [0002] In the world, the total amount of embedded systems is quite large, and some large industries, such as the specialized systems of the telecommunications industry, are widely distributed. Their function upgrades are usually realized by dynamically downloading application versions. However, as the application version is continuously upgraded, its version size becomes larger and larger, which will eventually exceed the capacity limit of the application version storage area. To deal with this problem, the following two solutions are generally adopted at present: [0003] 1. Take hardware revision, that is, expand the capacity of the version storage ...
