Embodiment Construction

[0013] The present invention will be further described below in combination with specific embodiments.

[0014] The invention is applied to the software startup of the set-top box. A compression software for compressing binary files is generated on the computer, compressing the main application. Modify the makefile and configuration file of the main application program. In order to achieve the purpose of compression, the memory (RAM) position is virtualized as ROM memory, which is used to store the code segment and data segment of the main program, that is, the main application program of the set-top box generated by compilation. The code segment and data segment are defined in the memory (RAM) location in the ROM location of the FLASH memory. The binary file of the successfully compiled main application program is compressed by the compression software to generate the compressed binary file of the main application program. The compressed binary file of the main application ...

Abstract

The invention relates to an embedded technology. Directed at the problem that increase of application software function of a set-top box can result in increase of hardware cost, the invention discloses a software decompressing starting method. The technical scheme comprises the following steps: a, compressing a main application program and writing to a FLASH memory; b, executing the first instruction of a loading program; c, reading the main application program from the FLASH memory; d, decompressing the main application program to a memory, jumping to the first instruction of the main application program of the memory; e, copying the main application program and data to the memory; and f, jumping to the main application program and data of the memory, and executing the main application program. The method is applied to embedded type products. The method adds the application software functions of the embedded type products without increase of FLASH memory resource and memory resource.

Description

technical field [0001] The invention relates to embedded technology, in particular to a method for starting main application software of a digital set-top box through software compression and decompression technology. Background technique [0002] With the widespread use of embedded products, such as set-top boxes commonly used now. Because people's software application functions of embedded products are increasing and becoming more and more complex, the application software is becoming larger and larger, and larger FLASH memory resources are needed to store the corresponding application software. However, adopting the existing method for starting the software of the embedded product increases the hardware cost of the embedded product while increasing the software functions of the application software. For example, the division of the software of the set-top box in the FLASH memory mainly includes two software modules: the loading software and the main application software....
