1Productivity
If the GPU operates at full power to maintain high processing capability and graphics quality, then processing performance is improved, but power consumption increases and heat generation occurs
Solution Approach 1:
The system dynamically adjusts texture processing quality based on power availability. The GPU operates at full quality when power is sufficient, but automatically degrades to reduced precision processing when power limits are detected, allowing continuous operation across varying power conditions without manual intervention.
Solution Approach 2:
The patent changes the precision parameter of texture processing operations. By switching between full precision and reduced precision modes, the system alters the computational complexity and power consumption characteristics of the GPU while maintaining continuous operation.

By monitoring power limits and using them to trigger quality degradation, the system transforms a constraint into an automatic thermal management strategy that prevents overheating while maintaining operation.
3Duration of action of moving object
If the GPU enters power-limited mode with reduced precision processing, then power consumption is reduced and battery life is extended, but graphics quality deteriorates
Solution Approach 1:
The system applies partial precision processing instead of full precision when power is limited. By using reduced precision texture processing, the GPU consumes less power to extend battery life while maintaining sufficient visual quality for most viewing conditions, accepting a controlled degradation in graphics fidelity.

AI summary
Power management techniques include a graphics processing unit (GPU) in which the GPU determines whether it is operating outside an operational limit and, when the GPU is operating outside the operational limit, the GPU alters performance of an operation to be performed texture processor within the GPU to reduce complexity of the operation. Otherwise, the GPU may perform the texture processing operation at its default complexity. These techniques provide a degree of power control not available in other techniques.
