Solution Overview
Problem
Existing electronic devices face inefficiencies in adjusting display parameters for image processing circuitry due to changing operating conditions on a frame-to-frame basis, leading to time-consuming and resource-intensive computations, which can result in perceivable image artifacts.
Innovation Solution
An acceleration sub-system offloads repetitive tasks from software and hardware components to hardware accelerators, such as processors and accelerators, to efficiently determine and apply display parameters for image processing circuitry, reducing computational burden and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display parameters are adjusted based on operating conditions for each frame, then image quality is improved, but computational time and resource consumption increase
Solution Approach 1:
The system performs display parameter adjustments in advance before the frame is displayed, rather than computing them at the last moment. By determining display parameters based on operating conditions received earlier in the frame timeline, the system ensures image quality adjustments are ready before rendering, eliminating computational delays that would cause front-of-screen artifacts.
2Measurement precision
If multiple display parameters are adjusted based on operating conditions, then image processing accuracy is improved, but computational burden increases
Solution Approach 1:
The system divides the computational task of adjusting multiple display parameters into separate, independent hardware accelerator units. Each hardware accelerator is dedicated to computing a specific display parameter (e.g., brightness, contrast, color temperature) based on operating conditions, allowing parallel computation that reduces overall computational burden while maintaining high image processing accuracy.
3Adaptability or versatility
If image processing circuitry is adjusted immediately before frame display, then adaptability to operating conditions is improved, but latency increases causing front-of-screen artifacts
Solution Approach 1:
The system receives operating conditions and determines display parameters in advance of the frame display timeline, completing all adjustments before the frame reaches the display buffer. This preliminary computation eliminates latency-induced front-of-screen artifacts while maintaining real-time adaptability to changing operating conditions through continuous monitoring and periodic parameter updates.
4Adaptability or versatility
If software and hardware components perform display parameter computations, then flexibility is improved, but processing speed decreases
Solution Approach 1:
The system replaces general-purpose software and hardware computation with specialized hardware accelerators designed specifically for display parameter computation. These dedicated hardware units execute fixed-function algorithms for calculating display parameters based on operating conditions, providing deterministic high-speed processing that software-based approaches cannot match, while still maintaining flexibility through configurable accelerator units.

AI summary
Systems and methods include an electronic device with an acceleration sub-system to perform (e.g., accelerate) certain functions offloaded from software and/or hardware components within the electronic device. For example, the acceleration sub-system may receive an operating parameter and perform one or more functions using the operating condition to determine a display parameter for the image processing circuitry. For example, a first hardware accelerator may perform math functions, a second hardware accelerator may perform interpolations, a third hardware accelerator may perform precision and/or format conversions, and so on. By offloading the functions to the hardware accelerators, the software and/or hardware components of the electronic device may perform other functions, such as determining additional display parameters for the image processing circuitry. As such, the image processing circuitry may be adjusted prior to a frame of image data being displayed, thereby reducing or eliminating front-of-screen errors.
