Advances in VLSI manufacturing have enabled designers to place tens of millions of gates on a single die at a reasonable cost and create Systems-on-Chip (SOCs). An SOC, which can make use of reusable cores, is a reasonably complete, functional subsystem. In general, an SOC contains a wide variety of elements: processor core, embedded memory, random logic, and analog circuitry, as well as peripherals. The emergence of SOC technology has ushered in a spectrum of opportunities to build
low-power, miniaturized appliances.
