Embodiment Construction

[0019] The upgrading system and upgrading method of the present invention will be described in further detail below in conjunction with a preferred embodiment.

[0020] Please refer to Fig. 1, wherein shows the structural block diagram of upgrade system of the present invention, and this upgrade system is used for carrying out aerial upgrade to the embedded system based on DSP, can be applied to all kinds of mobile terminals based on DSP system, more typically, can Applied to digital TV set-top boxes. 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 .

[0021] 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 st...

Abstract

The invention provides an upgrade system and an upgrade method based on DSP, which is used for the upgrade of the embed-type system based on the DSP. The invention comprises that: the upgrade data is obtained from the transmission flow by a multiplex module; by starting the load module, the initialization of a hardware device is implemented and the flash memory stored with the procedure of starting load and DSP main procedure is distributed; the upgrade state of an embed-type system is learnt in real time by providing a mutual module for the user. The manpower service problem of the existing system upgrade is resolved by adopting the upgrade system and the upgrade method of the invention, thereby saving the upper manpower cost and providing the operation method with convenience, reliability and low cost for the operation of the project and the upgrade of the latter increment upgrade.

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] In order to achieve the above object, the prese...
