Intermittent Data Processing Apparatus Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data processing apparatuses face high power consumption due to offset currents and clock signals when processing continuous audio-visual data and broadcast signals, despite improvements in wireless communication operability and power-saving features during intermittent operations.
Innovation Solution
A data processing apparatus that temporarily stores received data, processes it intermittently using a signal processing unit, and controls clock and power supplies to minimize consumption during non-operating periods, employing a signal processing control unit and clock/power control unit to manage processing speed and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus continuously supplies power and clock signals to maintain wireless communication operability, then the operability is improved, but the power consumption increases due to offset currents
Solution Approach 1:
The apparatus employs periodic action by intermittently operating the broadcast wave receiving unit and signal processing unit. The timer unit triggers the control unit to start up these components only when needed for receiving and processing broadcast data, rather than keeping them continuously active. This periodic operation eliminates offset currents during non-operating periods while maintaining the ability to receive and process broadcast signals when required.
2Use of energy by moving object
If the apparatus stops power supply during non-operating periods to reduce power consumption, then the power consumption is decreased, but the apparatus cannot process continuous data in real-time
Solution Approach 1:
The apparatus applies preliminary action by accumulating processed data in the output data storage unit before transmission is needed. The signal processing unit processes broadcast data and stores it in advance in the output data storage unit, so that when the apparatus enters low-power mode, the accumulated data can be transmitted without requiring continuous real-time processing. This allows the system to stop processing during non-operating periods while still maintaining data transmission capability.
3Productivity
If the apparatus processes data at real-time speed continuously, then the data transmission is smooth, but the power consumption remains high
Solution Approach 1:
The apparatus uses periodic action by processing data in intermittent bursts rather than continuously at real-time speed. The timer unit and control unit orchestrate periodic operation cycles where the signal processing unit processes multiple data items in succession during active periods, then the apparatus enters low-power mode. This periodic processing approach maintains adequate data transmission while dramatically reducing power consumption compared to continuous real-time processing.

AI summary
A data transmitting apparatus for processing data to be transmitted to a data receiving apparatus which reproduces received data stored in a received data storage unit, comprising: a signal processor for processing data; a transmitter for wirelessly transmitting the data processed in the signal processor to the data receiving apparatus; a signal processing controller for controlling the signal processor to operate intermittently; a clock/power controller for restricting a clock signal supply and/or power supply to the signal processing controller during a non-operating time period of the intermittent operation; and a wake-up controller for lifting the restriction put by the clock/power controller based on an amount of data stored in the received data storage unit.
