The system upgrade package provided by the terminal equipment manufacturer is usually a differential upgrade package, that is, a data package containing difference information between the current system version and the upgraded target version of the equipment is generated by a differential algorithm. The differential algorithm involves operations such as data partitioning, difference finding, instruction generation, data compression and the like. There are also a few system upgrade packages that use full packages, and the making of full packages also involves data blocking, instruction generation, data compression, and so on. The relevant algorithms of each operation need to be adjusted according to the specific ECU, so that the upgrade package with better upgrade performance can be manufactured.
At present, firmware upgrading performed in the industry based on the FOTA technology generates an upgrade package (a differential package or a full package) based on a firmware version, then issues the upgrade package to a cloud, and then issues the upgrade package to a terminal device, and the terminal device calculates new version data by using current version data of the terminal device and data in the upgrade package through a certain reduction algorithm and writes the new version data into a related storage address.
