They are in embedded systems like cell phones, PDAs, digital cameras, camcorders, game machines, iPods, MP3 players, CD players, DVD recorders, wireless routers, TV sets, GPS receivers, laser printers, cars, and many more consumer products. Most of these use modern 32-bit and 64-bit chips, and nearly all of them run a full-blown operating system. Taking a close look at one operating system popular in the embedded systems world: Symbian OS, Symbian OS is an operating system that runs on mobile ‘‘smartphone’’ platforms from several different manufacturers. Smartphones are so named because they run fully-featured operating systems and utilize the features of desktop computers. Symbian OS is designed so that it can be the basis of a wide variety of smartphones from several different manufacturers. It was carefully designed specifically to run on smartphone platforms: general-purpose computers with limited CPU, memory and storage capacity, focused on communication. Our discussion of Symbian OS will start with its history. We will then provide an overview of the system to give an idea of how it is designed and what uses the designers intended for it.
