Abstract

The invention discloses an electronic device with programs capable of being updated in a segmented manner. The electronic device comprises a processing unit and a central processing unit with a flash memory. The flash memory comprises a main program bank, a plurality of independent program banks and a temporary storage bank, the main program bank comprises a main program bank and an auxiliary program bank, and the auxiliary program bank comprises a first skip list and a first auxiliary program area. A main program can be executed in the main program bank by the processing unit, and the first skip list can be called to be connected with the first auxiliary program area by the main program bank. The various independent program banks respectively comprise second skip lists and second auxiliary program areas. The second skip lists can be called to be connected to the second auxiliary program areas in the independent program banks by the processing unit. The temporary storage bank is used for storing program codes downloaded from far ends, and the program codes can be updated into at least one of the independent program banks or the main program bank by the processing unit.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device that can be updated in sections. Background technique [0002] Currently, most of the electronic devices on the market can be updated through a remote program update method when they need to be updated. In the general remote program update, in order to avoid the failure of the update for safety considerations, the memory capacity of the electronic device must at least reserve the same memory capacity as the host program at the end of the memory, so that it can execute the remote program When the update fails, the old program can still be executed. [0003] In the above-mentioned existing remote program update method, a certain amount of memory capacity must be reserved to store the old programs on the host computer, and the host computer must additionally increase the memory capacity, which is relatively wasteful in terms of cost. Furthermore, if it is only through t...
