Abstract
A processor includes at least one core, a power control unit, and a first interconnect to couple with a peripheral controller. The first interconnect is to provide a first uni-directional communication path for communication of first power management data from the processor to the peripheral controller. Other embodiments are described and claimed.
Claims20
A processor comprising:
- at least one core;
- a power control unit;
- and
- a first interconnect to couple with a peripheral controller, wherein the first interconnect is to provide a first uni-directional communication path for communication of first power management (PM) data from the processor to the peripheral controller.
1 more element
A system comprising:
- a processor including at least one core and a communications controller to control power management communications between the processor and a peripheral controller;
- a first interconnect to couple the processor to the peripheral controller, the first interconnect to provide a first uni-directional data path from the processor to the peripheral controller to communicate first power management (PM) data;
- a second interconnect to couple the peripheral controller to the processor, the second interconnect to provide a second uni-directional data path from the peripheral controller to the processor;
- and
- a dynamic random access memory (DRAM) coupled to the processor.
2 more elements
A method comprising:
- communicating power management data from a processor to a peripheral controller via a first uni-directional data path comprising a first interconnect;
- and
- receiving response data to the power management data at the processor from the peripheral controller via a second interconnect that is distinct from the first interconnect;
- wherein the first interconnect and the second interconnect are distinct from a primary interconnect to carry data other than the power management data and the response data.
