As opposed to general purpose computing systems, where execution speed is the first and often only concern of the designer, embedded systems usually demand a much greater emphasis on low power usage and low memory and storage space usage. This is due to the more stringent design constraints of embedded systems: they are often battery powered, featuring only a small amount of storage and memory space. Over the last decade, a lot of research has been done into addressing the memory and storage space usage problem. Techniques have been developed that allow for the static analysis and transformation of whole programs. This paper evaluates a number of these techniques on a minimal Linux kernel, configured specifically for one hardware platform.
