Super I/O Controllers
The Super I/O Controller is a single chip that performs many functions that used to take several pieces of hardware in the past. This standardizes and simplifies the design, and thus reduces cost. The Super I/O chip typically is responsible for controlling the slower-speed, mundane peripherals found in every PC. Since these devices have been mostly standardized, they are virtually the same on every PC and it is easier to integrate these into a commodity chip instead of worrying about them for each motherboard design.
