Unified Module Data Packets for Multi-Interface Circuit Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of multiple modules in electronic devices, such as processors, displays, and cameras, is hindered by conflicting interface standards, leading to complex protocol standards and large circuit areas, which contradicts the user demand for lighter and thinner devices.
Innovation Solution
A unified protocol standard is implemented for inter-module data transmission, using a common data packet structure with data type information to identify application scenarios, allowing modules like cameras, displays, and storage to communicate via a single protocol, reducing circuit complexity and area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different interface standards are used for different modules (camera, display, storage), then each module can have optimized dedicated interfaces, but the protocol standard becomes complex and circuit area increases
Solution Approach 1:
The patent applies universality by designing a unified interface standard that can handle multiple application scenarios (camera, display, storage, etc.) through a single protocol. The data packet structure includes an application scenario field that identifies the type of data being transmitted, allowing the same physical interface to be used for different functions without requiring separate dedicated interfaces for each module.
2Reliability
If different interface standards are used for different modules, then each module can have optimized dedicated interfaces, but circuit area required for function implementation increases
Solution Approach 1:
The unified interface standard enables a single physical interface to serve multiple modules (camera, display, storage), reducing the need for separate dedicated interfaces for each module. This multi-functionality directly reduces the circuit area required while maintaining optimized communication capabilities for each application scenario through software-based protocol handling.
3Device complexity
If a unified protocol standard is used for all modules, then circuit area is reduced and design is simplified, but different application scenarios require different protocol specifications
Solution Approach 1:
The patent applies local quality by including an application scenario field within the data packet structure that identifies the specific type of data being transmitted (camera, display, storage, etc.). This allows the unified protocol to adapt to different application scenarios on a per-packet basis, with each packet containing the necessary information for the receiving end to process it appropriately for the specific application.
4Reliability
If multiple dedicated physical layer interfaces are processed, then each interface can be optimized for its specific function, but the design process becomes difficult
Solution Approach 1:
The unified interface standard eliminates the need to process multiple conflicting dedicated physical layer interfaces by providing a single standardized interface that can handle all modules. This simplifies the design process while maintaining optimized communication capabilities through the application scenario identification mechanism in the data packet structure.

AI summary
A method includes: A first transmission unit packs, at a protocol layer of the first transmission unit, to-be-transmitted data of an application layer of the first transmission unit, to generate a data packet. The data packet includes data type information, the data type information indicates an application scenario of the data packet, and the application scenario includes any one of a camera scenario, a display scenario, and a storage scenario. The first transmission unit sends the data packet to a physical layer of the first transmission unit through the protocol layer of the first transmission unit. The first transmission unit sends the data packet to a second transmission unit through the physical layer of the first transmission unit.
