POWER DEMAND REDUCTION FOR IMAGE GENERATION FOR DISPLAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17997198 titled 'POWER DEMAND REDUCTION FOR IMAGE GENERATION FOR DISPLAYS
Simplified Explanation
The patent application describes a method for reducing power demand in image generation for displays by skipping the rendering of frames that are highly similar. Here are the key points:
- The method involves receiving a first set of draw calls from a game engine by a CPU circuit.
- A second set of draw calls is provided to the CPU circuit.
- The CPU circuit compares the second set of draw calls to the first set of draw calls.
- If there is a change in at least one parameter that exceeds a threshold, the second set of draw calls is sent to a GPU circuit for rendering.
- If the change in selected parameters is below the threshold, an earlier rendered image is sent to the display, omitting the usage of the GPU circuit for that frame.
Potential applications of this technology:
- Video game consoles and gaming PCs can benefit from reduced power consumption during image generation.
- Mobile devices, such as smartphones and tablets, can extend battery life by skipping unnecessary rendering.
- Virtual reality and augmented reality devices can optimize power usage while maintaining a smooth user experience.
Problems solved by this technology:
- Reduces power demand during image generation, leading to energy savings and longer battery life.
- Prevents unnecessary rendering of highly similar frames, improving overall system efficiency.
- Helps maintain a consistent frame rate and smooth user experience by utilizing the GPU circuit only when necessary.
Benefits of this technology:
- Energy-efficient image generation reduces power consumption and environmental impact.
- Longer battery life for portable devices, allowing for extended usage without the need for frequent recharging.
- Improved system performance and responsiveness by optimizing the usage of CPU and GPU resources.
Original Abstract Submitted
Power demand reduction for image generation for displays skips rendering of frames that are highly similar based on a comparison of certain parameters associated with draw calls. A first set of draw calls is received from a game engine by a central processing unit (CPU) circuit and then a second set of draw calls are provided to the CPU circuit. The CPU circuit compares the second set of draw calls to the first set of draw calls. If there is a change in at least one parameter that exceeds a threshold, then the CPU circuit sends the second set of draw calls to a graphics processing unit (GPU) circuit for rendering. If, however, the change in selected parameters is below the threshold, then the CPU circuit sends an earlier rendered image to the display for presentation to the user, effectively omitting usage of the GPU circuit for that frame.
