The increasing popularity of high-speed 32-bit ARM based micro-controllers allowed Linux to enter the world of embedded devices. That is why the need of debugging its kernel and applications became essential. Since Linux is a true multi-process operating system, it utilizes a Memory Management Unit (MMU) to give each process a separate memory space.
