Communication Apparatus Power Saving via Dual Processing Unit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication apparatuses face challenges in achieving further power saving, as they require frequent transitions from sleep mode to non-sleep mode to process unprocessed packets, limiting the duration of the sleep mode and preventing the secondary processing unit from executing other processes for extended periods.
Innovation Solution
The communication apparatus employs a first processing unit that transitions between sleep and non-sleep modes, with a second processing unit capable of processing unprocessed packets in sleep mode, and interrupts packet processing if the continuous processing time exceeds an allowable period to allow for other processes, thereby prolonging the sleep mode and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first processing unit frequently transitions from sleep mode to non-sleep mode to process unprocessed packets, then packet processing is ensured, but power saving is limited
Solution Approach 1:
The patent divides the processing unit into two separate entities: a first processing unit that handles packet processing and a second processing unit that manages other tasks. This segmentation allows the first processing unit to remain in sleep mode longer while the second processing unit handles additional work, reducing overall power consumption while maintaining processing reliability.
Solution Approach 2:
The second processing unit acts as an intermediary that takes over other processing tasks when the first processing unit is in sleep mode. This mediator approach allows the system to maintain functionality across both units while optimizing the sleep duration of the power-intensive first processing unit.
2Productivity
If the second processing unit processes a large number of unprocessed packets continuously, then packet processing capacity is increased, but the second processing unit cannot execute other processes for extended periods
Solution Approach 1:
The patent implements periodic action by having the second processing unit alternate between processing packets and executing other processes. Instead of continuous packet processing, the system periodically switches tasks, allowing the second processing unit to maintain both high packet processing capacity and the ability to execute diverse processes over time.
Solution Approach 2:
The system dynamically adjusts the workload distribution between the two processing units based on current needs. The second processing unit can flexibly switch between handling packets and performing other tasks, creating a dynamic system that adapts to varying processing requirements while maintaining overall productivity.

AI summary
A communication apparatus that is to be connected to a network includes: a first processing unit configured to transition between a sleep state and a non-sleep state and configured to process a packet received via the network when the first processing unit is in the non-sleep state; and a second processing unit configured to process a packet when the first processing unit is in the sleep state, wherein the second processing unit is capable of executing packet-processing for sequentially processing of unprocessed packets, wherein the second processing unit includes a detecting section that detects a reception of the unprocessed packet, wherein, when the first processing unit is in the sleep state and the reception of the unprocessed packet is detected, the second processing unit starts the packet-processing, and wherein, the second processing unit terminates the packet-processing if a continuous packet-processing period exceeds an allowable time period.
