Abstract

The invention discloses an application loading method and device. The method comprises specific steps of selecting storage space for storing preset data segments in executable files of applications in a programmable read-only memory; copying the preset data segments to the memory and relocating the preset data segments based on an initial address of the storage space; copying the relocated preset data segments to the storage space by means of the method and the device, code ports of the executable files are relocated in the memory, the relocated code portions are then written back into the programmable read-only memory, and accordingly relocation of the code portions can be completed only through once erasing operation on storage blocks, and system overheads and loss of the programmable read-only memory in the application loading process are reduced.

Description

technical field [0001] The present application relates to the computer field, in particular to the application field, and in particular to an application loading method and device. Background technique [0002] In an embedded system, when loading an application, a common method is to store the binary code of the executable file in the flash memory, and directly run the instruction on the flash memory. During the application loading process, it is necessary to relocate the symbols in the assembly code of the application so that the symbols have absolute addresses, so as to load the application. [0003] However, when the above method is used to load the application, each relocation of the symbol corresponds to an erase operation of the entire storage block of the memory where the symbol is located, which greatly increases the system overhead and increases the consumption of the flash memory. Contents of the invention [0004] The present application provides an application...
