Abstract:
Embedded systems are quite often subject to severe resource constraints, and this makes it extremely challenging to develop embedded systems. Despite of rapid decrease in the price of solid state memory devices, system memory is still a very precious resource in embedded system development. In this paper, we present two effective techniques to significantly reduce the memory requirement of MMU-less uClinux based embedded systems. They are statically linked dynamically shared libraries and execute-inplace
(XIP). Without MMU, it is extremely difficult to support these techniques, and we present our solution approaches in detail. The end result of applying them is drastic - 50% of reduction in memory requirement. Even though they are applied to uClinux based embedded systems, they can be used for any MMU-less real-time operating systems.
