ARM processors started as devices manufactured by Acorn, a British company, for its line of PCs. Later, in a joint venture with Apple Computer and VLSI Technology, Acorn spun off Advanced RISC Machines, or ARM, as a separate company. ARM evolved the basic CPU architecture into a series of cores that it licenses to chip manufacturers such as Atmel, Texas Instruments, STMicroelectronics and others. The ARM architecture handles applications from low-cost, low-power devices served by the ARM7 core to high-end applications served by the ARM11 core.

ARM's latest offering, the Cortex architecture, comes in three versions: A, R and M, which target specific types of applications. The M Series is appropriate for cost-sensitive applications that employ a deeply embedded...
