System on chip (SOC)

System-on-chip (SOC) is an integrated circuit that includes a processor, a bus, and other elements on a single monolithic substrate. In recent years, there have been great advancements in the speed, power, and complexity of integrated circuits, such as application specific integrated circuit (ASIC) chips, random access memory (RAM) chips, microprocessor chips, and the like. These advancements have made possible the development of system-on-a-chip (SOC) devices. System on Chip (SOC) design is implemented in which various components, such as volatile memory systems, non-volatile memory systems, data signal processing systems, mixed signal circuits and logic circuits are each formed into units and integrated on a single chip. The primary advantages of SOC devices are lower costs, greatly decreased size, and reduced power consumption of the system. Digital systems using SOC design, such as those used in handheld digital products, has replaced bulkier and higher power consuming digital systems built on a board in a package having several chips. As technology advances, integration of various units included in a SOC design becomes increasingly complicated. An SOC device integrates into a single chip many of the components of a complex electronic system, such as a wireless receiver. SOC devices greatly reduce the size, cost, and power consumption of the system. A system on chip may include a configurable logic unit. The configurable logic unit includes a processor, interface, and a programmable logic on the same substrate. A system-on-chip is designed by stitching together multiple stand-alone VLSI designs (cores) to provide full functionality for an application.
