Multi-Link Interface Modes Matched to Link Data Rates for Power Control

Solution Overview

Problem

The mismatch between the maximum data rate of channels generated between electronic devices and the data rate supported by the operating mode of the interface can lead to decreased data transmission rates and increased power consumption.

Innovation Solution

An electronic device identifies the maximum data rate of multiple links based on capability information from an external device and selects an operating mode for the interface that supports a higher data rate, preventing bottlenecks and optimizing power consumption.

If the interface operates in a high data rate mode, then data transmission speed is improved, but power consumption increases

Engineering Contradiction:

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The interface operating mode is dynamically adjusted based on the actual data rate requirements of the communication links. The processor determines the maximum data rate needed and selects an operating mode that matches this requirement, allowing the system to transition between different power states (L0, L1, L2, L3) to optimize both performance and energy efficiency

Inventive Principle:

Solution Approach 2:

The system changes the operating parameters of the interface by selecting different operating modes (L0, L1, L2, L3) with different maximum data rates. This allows the interface to adapt its performance characteristics and power consumption levels to match the actual communication requirements, avoiding unnecessary energy expenditure when high data rates are not needed
