Description
Technical field
The present invention relates to a kind of programmed method, more particularly to a kind of On-board programming method of On-board software.
Background technology
On-board software runs in satellite platform or the unit of load, cooperateed with other soft on star as embedded software
Hardware completes the critical functions such as various information processings and interaction, satellite in orbit when, the defects of due to software itself, function liter
The reasons such as level need to realize the in-orbit change of software code or upgrade maintenance, and this is particularly important in actual applications, in-orbit
Programming substantially increases availability, life-span and the reliability of satellite, has great economic and social benefit.On-board software is general
It is stored in PROM (programmable read only memory) memories or EEPROM (the read-only storages of electrically erasable of computer
Device) in memory, code calculator memory SRAM (static random-access can be loaded into according to being actually needed after computer power-up
Memory) in run, PROM can not realize the direct modification to On-board software code, generally use due to that can not program repeatedly
On-board programming method be that the function that is modified of needs is called indirectly by function address table, in call function,
It is new by being noted on ground when the function needs to be modified by the address of the function in query function address table come complete call
Function code into SRAM, and note the function address in number Modification growth function address table, be allowed to point to the SRAM addresses of new function,
The replacement of function is completed, although this method realizes the function of On-board programming, but some following deficiency be present：Shortcoming is flexible
Property, when carrying out Software for Design it needs to be determined that can On-board programming function, adjusted indirectly if not by function address table
Function can not be changed；On-board programming code can not solidify, when spaceborne computer is restarted or failure and other reasons can be direct
Cause the loss of On-board programming code, it is necessary to number is noted on ground again, make troubles in actual applications；Software maintenance is difficult, soft
