Method and device for decompressing mobile terminal zip file

Abstract

The invention discloses a method and a device used for decompressing the compressed packet of a movable terminal; the method comprises the steps as follows: a PC decompression engine is transplanted and a decompression interface is provided for the decompression engine; the decompression interface is internally provided with a decompression filtration field; when the decompression interface is called to decompress the compressed packet, the decompression engine jumps over the content of the compressed packet corresponding to the decompression filtration field and decompresses the other content in the compressed packet. The method and the device can effectively reduce the system expense during the decompression process of the movable terminal and improve the decompression efficiency of the movable terminal.

Description

Technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for decompressing a compressed package of a mobile terminal and a device for decompressing a compressed package of a mobile terminal. Background technique [0002] Since the memory of mobile terminals, especially non-smart mobile terminals, is very limited, for example, most non-smart mobile terminals leave users with less than 200K of memory for storage; even if they supplement the use of extended memory cards with relatively large storage space, it is difficult to satisfy users. Demand for use. In this case, the data used by some clients, such as e-books or update programs, are generally stored in the mobile terminal in the form of compressed packages, in an effort to reduce the storage space occupation. [0003] The introduction of the above-mentioned compressed package inevitably requires the mobile terminal to provide corresponding decompression technology to re...

Problems solved by technology

[0002] Due to the limited memory of mobile terminals, especially non-smart mobile terminals, for example, most non-smart mobile terminals have less than 200K of memory left for users to store; usage requirements

[0004] However, compared with PCs, mobile terminals, especially non-intelligent mobile terminals, not only have limited memory, but also have relatively weak chip processing capabilities. Therefore, the above-mentioned PC-based decompression technology is undoubtedly quite difficult to implement by chips in mobile terminals, resulting in There are a series of problems such as slow decompression speed, and there is also the problem of data memory usage after decompression

The above problems make the realization of decompression technology not only a highlight but also a difficulty in mobile terminal technology.
