Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The serial restoration process of device interface controllers during a computing device's boot sequence leads to increased power on latency, affecting efficiency and user experience, especially with growing numbers of interface controllers.
Innovation Solution
Implementing a parallelized boot sequence using special purpose processors to restore previously-trained operational parameters and cached data in parallel, reducing the reliance on general purpose processors and enabling simultaneous restoration across multiple controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If device interface controllers are restored serially during boot sequence, then the restoration process is simple to implement, but power on latency increases
Solution Approach 1:
The boot sequence is segmented into multiple parallel restoration tasks, each handled by a dedicated special purpose processor. Each processor independently restores specific device interface controllers simultaneously, dividing the monolithic serial restoration process into concurrent parallel segments that reduce overall power on latency.
Solution Approach 2:
Device interface controllers are restored to operational state before the main processing begins. The special purpose processors perform preliminary restoration of controllers in parallel during the boot sequence, ensuring that all necessary components are ready before the general purpose processor initiates main operations, thereby reducing waiting time and power on latency.
2Adaptability or versatility
If more device interface controllers are added to the system, then system functionality increases, but power on latency increases due to serial restoration
Solution Approach 1:
The system architecture segments restoration responsibilities across multiple special purpose processors, allowing each processor to handle specific device interface controllers independently. This segmentation enables linear scalability where adding more controllers can be accommodated by distributing them across the parallel processor pool, maintaining constant power on latency regardless of system functionality expansion.
Solution Approach 2:
Special purpose processors are designed with universal restoration capabilities that can handle multiple types of device interface controllers. Each processor can restore various controller types (memory controllers, I/O controllers, etc.) depending on assignment, providing multi-functionality that allows the system to scale functionality without proportionally increasing restoration time.
