Dynamic Linking of modules

Hello All,

I am to design a dynamic linker/loader on Nucleus RTOS running on ARM9.
my aim is to conserve memory by loading only the required (one or more)
modules and offload other modules.
I checked out to find that the code can be compiled position independent
using the armcc compiler. also the executable format produced by armcc is
ELF(elf32-little).
I need pointers in how to design this dynamic linker as well as the
loader.

My Work Environment
Processor :ARM9
RTOS :Nucleus
Tool suite :RVDS for ARM9


Thnks and Rgds
