Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with embedded networking capabilities incur high system costs due to the need for additional microprocessors and low-latency memories, making it expensive to add network functionality.
Innovation Solution
A display system that utilizes on-chip low-latency memories for both video/image data storage and networking operations, eliminating the need for an extra network controller by storing and executing networking codes within the existing memory structure, allowing for seamless switching between display and networking modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional microprocessors and low-latency memories are added to provide networking capability, then networking functionality is improved, but system cost increases
Solution Approach 1:
The existing low-latency memory in the display device is made multi-functional by allowing it to store both video/image data and networking codes. The memory management unit dynamically allocates memory space between display and networking functions, enabling a single memory resource to serve multiple purposes and eliminate the need for separate networking hardware.
Solution Approach 2:
The patent combines the networking functionality with the existing display control unit by integrating networking codes into the same memory space used for display operations. The microprocessor executes networking codes alongside display codes, merging what would traditionally be separate functional units into a single integrated system.
2Speed
If on-chip low-latency memory is used for networking operations, then networking performance is improved, but memory cost increases
Solution Approach 1:
The memory allocation is made dynamic rather than static. The memory management unit continuously monitors and adjusts the partitioning of low-latency memory between display and networking functions based on real-time operational requirements. This dynamic allocation allows the system to optimize performance for either function as needed while efficiently utilizing the available memory resources.
Solution Approach 2:
The system changes the operational parameters of the low-latency memory by reconfiguring its usage patterns. When networking operations are required, the memory parameters are adjusted to allocate sufficient space for networking codes and data, while maintaining the capability to switch back to display-only mode when networking is not needed.
