Embodiment
[0023] Such as figure 1 As shown in , an on-orbit fine-grained function adding method, the function adding method is as follows: define the function that needs to be added as a dedicated segment through the link script, and locate it at the end of the program, so that the memory can be effectively used If there is no space to use, copy the exclusive segment through a special tool, upload it to the memory of the on-orbit star system, and add the address of this function to the function lookup table, waiting for the execution of the task.
[0024] The steps of the method for adding the above function function are as follows:
[0025] Step 1: Generation of incremental files: define the functions that need to be added as exclusive segments through the link script, and locate them at the end of the program, so that the unused space of the memory can be effectively used, and the exclusive segments can be copied out through special tools , to generate incremental files, the specific...
