Embodiment Construction

[0018] The upgrading system and upgrading method of the present invention will be described in further detail below in conjunction with a preferred embodiment.

[0019] see figure 1 , which shows the structural block diagram of the upgrade system of the present invention, the upgrade system is used to upgrade the embedded system based on DSP in the air, can be applied to various mobile terminals based on the DSP system, more typically, can be applied to digital TV set top box. As shown in the figure, the upgrade system of the present invention includes a demultiplexing module 1 , a bootloading module 2 , a flash memory (Flash) 3 and an interaction module 4 . Wherein, the upgrade system receives a transport stream (TS code stream) from the outside. For a digital TV set-top box, the TS code stream is an encapsulated data packet containing digital TV signal data, and the upgrade data is encapsulated in the form of private data. In the TS code stream.

Abstract

The invention provides a DSP-based upgrade system and an upgrade method, which are used to upgrade a DSP-based embedded system, which includes: using a demultiplexing module to obtain upgrade data from a transport stream; using a startup loading module to execute hardware The initialization of equipment, and the flash memory that stores the program that boots up and loads and DSP main program is distributed; Provide the user real-time understanding situation that described embedded system upgrade is carried out by interactive module, utilize upgrade system of the present invention and upgrade method to be able to It solves the manual service problem of the existing system upgrade, thereby saving the labor cost in the later period, and provides a convenient, reliable and low-cost implementation method for the implementation of the project and the upgrade of the value-added modules in the later period.

Description

technical field [0001] The invention relates to a DSP-based upgrade technology, in particular to an upgrade system and an upgrade method for an embedded system. Background technique [0002] For mobile terminals based on DSP systems, customizability is the key to their rapid acceptance by the market. In this case, the version upgrade problem caused by software customization is part of the humanized design of the product. [0003] The current set-top box upgrade method based on the DSP system still relies on the emulator for manual upgrade. The increase in maintenance costs and the complexity of the upgrade hinder the application and service promotion of the DSP-based system in the commercial field. Contents of the invention [0004] The purpose of the present invention is to provide an upgrade system and method based on a DSP embedded system, so as to solve the manual service problem of the existing system upgrade. [0005] For achieving the above object, the present inv...
