Coexistence Hub Coordinates Multi-SoC Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face issues such as resource usage collisions, interference in shared communication bands, and operational incompatibilities among multiple System on Chips (SoCs), which are typically resolved by a central processor, leading to inefficiencies and increased power consumption.
Innovation Solution
A communication hub device autonomously coordinates SoC operations over a multi-drop bus, executing an operation policy without significant central processor intervention, enabling faster coordination and reduced power consumption by broadcasting coexistence messages to manage resource usage and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central processor coordinates operations of multiple SOCs, then coordination and conflict resolution are achieved, but power consumption increases and coordination speed decreases
Solution Approach 1:
The patent divides the coordination function into two segments: a central processor that defines operation policies and a communication hub that autonomously executes them. This segmentation allows the central processor to remain in low-power mode while the communication hub handles real-time coordination, resolving the contradiction between coordination capability and power consumption.
Solution Approach 2:
The communication hub acts as an intermediary between the central processor and multiple SOCs. It receives operation policies from the central processor and autonomously coordinates SOC operations based on these policies, eliminating the need for continuous central processor intervention and reducing overall power consumption while maintaining coordination effectiveness.
2Reliability
If a central processor coordinates operations of multiple SOCs, then conflict resolution is achieved, but coordination response time increases
Solution Approach 1:
The central processor performs preliminary action by defining comprehensive operation policies that cover various conflict scenarios before SOCs operate. The communication hub then executes these pre-defined policies autonomously in real-time, enabling fast conflict resolution without waiting for central processor intervention, thus improving coordination response time while maintaining reliability.
3Adaptability or versatility
If multiple SOCs are integrated into the electronic device, then functionality and communication capability increase, but resource usage collisions and interference occur
Solution Approach 1:
The communication hub implements feedback mechanisms by monitoring the operational states of multiple SOCs in real-time and dynamically adjusting their operations based on detected conflicts or interference. This feedback loop enables the system to maintain high communication functionality while automatically resolving resource collisions and interference issues.

AI summary
Embodiments relate to coordinating the operations of subsystems in a communication system of an electronic device where a coexistence hub device monitors the state information transmitted as coexistence messages over one or more multi-drop buses, processes the monitored coexistence messages and sends out control messages as coexistence messages to other systems on chips (SOCs). The coexistence hub device can also update the operations of the communication system. The coexistence hub device may receive an operation policy from a central processor and may execute the operation policy without further coordination of the central processor. The coexistence hub device broadcasts the control messages as coexistence messages according to the executed operation policy.
