1Quantity of substance
If conventional video encoding algorithms are used for high-resolution video signals with high motion and scene complexity, then video compression is achieved, but computational burden increases significantly
Solution Approach 1:
The patent implements dynamic voltage and frequency adjustment of ring oscillators based on operational mode (encoding/decoding) and activity level. The control circuit monitors operation type and dynamically modifies power supply voltage and clock frequency to match actual processing demands, reducing unnecessary computational overhead while maintaining compression performance
Solution Approach 2:
The system changes physical parameters (voltage and frequency) of the ring oscillators to optimize performance. By adjusting voltage to match operational mode (encoding vs. decoding) and activity level, the system achieves efficient video compression with reduced computational burden compared to fixed-parameter designs
2Productivity
If power supply voltage and clock frequency are increased to improve video processing performance, then encoding and decoding efficiency improves, but power consumption increases
Solution Approach 1:
The control circuit dynamically adjusts voltage and frequency based on real-time operational conditions. During encoding operations or high-activity periods, higher power settings are applied to maximize processing efficiency. During decoding or low-activity periods, power is reduced, optimizing the balance between productivity and energy consumption
Solution Approach 2:
The system uses feedback from the control circuit that monitors operation type (encoding/decoding) and activity level to continuously adjust power supply voltage and clock frequency. This closed-loop control ensures video processing efficiency is maintained while minimizing power consumption by avoiding unnecessary high-power operation
