A fine-grained software version upgrade method based on magic partition

Abstract

The invention relates to the technical field of software, in particular to a fine-grained software version upgrade method based on magic partitioning. The fine-grained software version upgrade methodbased on magic partitioning comprises the steps that a magic partitioning technology is adopted, an independent partition is built, the application and stored content of the partition are not assigned, according to the degree of importance of the application and fine-grained upgrade content of products, the application and write content of the partition are adjusted dynamically, and backup on system core content is achieved. According to the fine-grained software version upgrade method based on magic partitioning, the mode of conducting decompression and operation simultaneously is adopted, memory applied in the operation process can be greatly reduced, in the upgrade process, the fine-grained mode is adopted, the specific content in a version is upgraded in a targeted mode, configurationof all parts of the version upgrade content can be achieved, independent upgrade of the content of all the parts is achieved, and the problem of upgrading a large amount of needed memory and nonvalatile storage media at a time is solved.

Description

technical field [0001] The invention relates to the technical field of software, in particular to a method for upgrading fine-grained software versions based on magic partitions. Background technique [0002] The software version upgrade activity is one of the main activities in the maintenance phase of the software life cycle. The quality of the version upgrade method is directly related to the after-sales quality of the entire product, the stability of the product, and the expansion of product functions. In the field of embedded equipment and communication, because the cost of chips such as memory chips as storage media and non-volatile storage media such as ROM, Flash, and hard disks often accounts for a large proportion of the entire equipment cost, the operation of these storage chips and equipment software , software version upgrade activities are closely related. A good version upgrade method can fully integrate the storage resources of the device, and use as few st...

AI Technical Summary

Problems solved by technology

[0004] The existing upgrade solution is based on the full decompression of the version before running and the full download and full copy of the version to be upgraded, which has high requirements on the capacity of storage resources and cannot meet the cost control requirements of current products

At the same time, due to the full download and copy of the upgraded version, the requirements for network quality are high, and the version upgrade takes a long time. The high delay during the upgrade process greatly reduces the product experience, and the high network quality requirements also limit the application of the product. environment, which increases the risk of upgrade failure and reduces the overall stability of the product
