Integration of processor and input/output hub

摘要

Methods and apparatus for integration of a processor and an input/output hub are described. In one embodiment, a sideband signal may cause change in a power management state of a processor or an integrated I/O logic. A single integrated circuit die may include both the processor and the integrated I/O logic. Other embodiments are also disclosed.
