POWER MANAGEMENT FOR PERIPHERAL COMPONENT INTERCONNECT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111354 titled 'POWER MANAGEMENT FOR PERIPHERAL COMPONENT INTERCONNECT
Simplified Explanation
The abstract describes a new PCIe link state that can improve power saving capabilities of a PCIe link operating in a flow control unit (flit) mode.
- The innovation involves operating a data link with a host in a flit mode using fixed-sized packets.
- The data link is in a partial width link state (PLS) where a first set of lanes are in an electrical idle state and a second set of lanes are active for data traffic.
- The device can transition some lines of the second set of lanes to a partial width standby link state (PSLS) with lower power consumption than the active state.
Potential Applications
This technology could be applied in various devices that require power-saving features, such as mobile devices, IoT devices, and data centers.
Problems Solved
This innovation addresses the need for efficient power management in PCIe links, especially in scenarios where power consumption needs to be optimized without compromising data transfer performance.
Benefits
The technology allows for significant power savings without sacrificing data transfer capabilities, leading to improved energy efficiency and potentially longer battery life in portable devices.
Potential Commercial Applications
Potential commercial applications include mobile devices, IoT devices, networking equipment, and data centers where power efficiency is crucial for operation.
Possible Prior Art
One possible prior art could be existing power-saving techniques in PCIe links, such as dynamic link width adjustment or link state power management.
Unanswered Questions
How does this technology compare to existing power-saving techniques in PCIe links?
The article does not provide a direct comparison with other power-saving methods in PCIe links, leaving room for further analysis on the effectiveness and efficiency of this innovation.
What are the specific power consumption savings achieved by transitioning lanes to the PSLS?
The abstract mentions lower power consumption in the PSLS compared to the active state but does not quantify the exact power savings, which could be crucial information for potential users evaluating the technology.
Original Abstract Submitted
a new peripheral component interconnect express (pcie) link state can enhance power saving capabilities of a pcie link operating in a flow control unit (flit) mode. a device can operate a data link with a host in a flit mode using fixed-sized packets, the data link being in a partial width link state (pls) in which a first set of lanes of the data link are in an electrical idle state and a second set of lanes of the data link are in an active state available for data traffic with the host. the device can transition one or more lines of the second set of lanes from the pls to a partial width standby link state (psls) in which the one or more lines of the second set of lanes are in a standby state that has lower power consumption than the active state.
