Solution Overview
Problem
Existing electronic devices rely on fixed frequency clock signals, which do not adapt to changing environmental conditions, leading to inefficient operation and potential performance issues due to factors like temperature, voltage, and workload variations.
Innovation Solution
An electronic device equipped with an acquisition circuit, processing circuit, and a Time-Average-Frequency Direct Period Synthesis (TAF-DPS) clock generator that collects environmental information to determine a target frequency control word, generating a clock signal to adjust the device's operating status according to preset expectations, thereby optimizing performance across varying conditions.

Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed frequency clock signal is used, then the device structure is simple, but the device cannot adapt to environmental changes causing inefficient operation
Solution Approach 1:
The patent implements dynamic frequency adjustment by replacing the fixed frequency clock signal with a variable frequency clock signal generated by a TAF-DPS clock generator. The clock frequency is dynamically adjusted based on environmental parameters (temperature, voltage, workload) detected by sensors, allowing the system to adapt to changing conditions while maintaining operational efficiency.
Solution Approach 2:
The patent employs feedback mechanisms where environmental sensors continuously monitor temperature, voltage, and workload conditions, and this information is fed back to the TAF-DPS clock generator. The clock generator uses this feedback to automatically adjust the clock frequency, creating a closed-loop control system that optimizes performance based on real-time environmental conditions.
2Productivity
If frequency adjustment is added to adapt to environmental changes, then operational efficiency improves, but device complexity increases
Solution Approach 1:
The patent changes the frequency parameter of the clock signal dynamically based on environmental conditions. The TAF-DPS clock generator adjusts the clock frequency according to temperature, voltage, and workload parameters, optimizing operational efficiency without requiring fundamental changes to the device architecture.
Solution Approach 2:
The TAF-DPS clock generator serves multiple functions: it generates the clock signal, processes environmental sensor data, determines optimal frequency settings, and outputs the adjusted clock signal to functional circuits. This multi-functionality reduces the need for separate dedicated components for each task.
3Reliability
If environmental sensing and dynamic frequency control are implemented, then performance optimization is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the clock generation function with environmental sensing and frequency control capabilities into a single TAF-DPS clock generator module. This integration consolidates multiple functions into one component, simplifying the manufacturing process and reducing the number of discrete parts that need to be assembled.
