Dynamic constructing of small system based on object files

A technique aimed at constructing a small system dynamically based on object files was presented. The mechanism of this technique is to link object files dynamically and construct a small system. The advantage of this technique is the flexibility, which can be used in updating or modifying system dynamically, and it is very suitable in embedded environment. The dynamic constructing technique which used the object file of C language was described in detail, and a simple prototype was provided.
