Embodiment Construction
[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] One of the core ideas of the present invention is that the present invention uses a block replacement backup method, that is, blocks with the same logic between backup programs or resources can be replaced with each other arbitrarily, such as the first block and the second block of the first backup program The first block of the backup program can be replaced with each other; at the same time, the present invention implements a random replacement mechanism for each backup file, that is, when the program is loaded, it does not start loading at the first backup program or resource, but selects any file through the random loading mechanism. The backup program or resources start to load, that is, the first logical block can be t...

The invention provides a data backup loading method and device of an embedded device. The data backup loading method comprises the steps of: selecting a data backup file from a plurality of data backup files stored in a nandflash, and loading a first data block, wherein the data backup file comprises a plurality of data blocks, corresponding blocks among the data backup files can be mutually replaced; and selecting another data backup file from a plurality of data backup files stored in the nandflash, and loading the next data block; repeating the steps until the files are loaded completely. A block replacement method is used in backed-up data files (such as operation program files or resource files), so that the programs are more flexibly and conveniently replaced, meanwhile, the utilization rate of the backed-up programs is increased, the backup efficiency is remarkably increased, and backup number can be reduced. Furthermore, a random mechanism of backup data is added, so that read-write of the backup data is more uniform, and the possibility of using bad blocks for a long time is remarkably reduced.
Description
technical field [0001] The invention relates to the technical field of decoding, in particular to a data backup loading method and a data backup loading device for an embedded device. Background technique [0002] With the development of information technology, embedded system has become a very hot topic in the current IT industry. Because of a series of advantages such as high efficiency, low cost, high reliability, rich code, and application scalability and portability, it has become more and more the main force of industrial systems and civilian systems, especially in information products. , is increasingly applied to the concept of embedded systems (embedded devices). [0003] The data of general embedded devices (for example, application running programs and resource files) will be stored in nandflash. With the increase of data storage requirements of embedded systems (embedded devices), more embedded devices now use MLCnandfiash. [0004] SLC and MLC are the abbrevia...
