There is considerable interest in the ARM Cortex platform today because ARM devices are found everywhere. Units containing ARM devices range from the small microcontroller embedded systems to cellphones and larger servers running Linux. Soon, ARM will also be present in higher numbers in the datacenter. These are all good reasons to become familiar with ARM technology.
With the technology ranging from microcontrollers to full servers, the question naturally arises: “Why study embedded device programming? Why not focus on end-user systems running Linux, like the Raspberry Pi?”
The simple answer is that ...
