Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory cards experience low data transmission speeds in wireless scenarios, leading to poor signal quality and processor overload, which slows down devices and limits their ability to perform other tasks during data transfer.
Innovation Solution
A communication interface system with a first communication interface operating at a higher frequency between the memory unit and control unit, and a second interface operating at a lower frequency between the control unit and host unit, allowing for simultaneous data transfer and command processing without waiting for complete data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission speed is increased, then signal quality is improved, but processor workload increases
Solution Approach 1:
The patent segments the data transmission process into two independent interfaces: a first communication interface between memory unit and control unit, and a second communication interface between control unit and host unit. This segmentation allows the control unit to manage data flow independently, enabling high-speed transmission without overloading the processor, as the control unit handles the heavy lifting of data management.
Solution Approach 2:
The control unit acts as an intermediary between the memory unit and the host unit. It receives data from the memory unit via the first communication interface and forwards it to the host unit via the second communication interface. This intermediary role allows the control unit to buffer and manage data flow, enabling high transmission speeds while preventing processor overload by handling data management tasks independently.
2Reliability
If data transmission speed is increased, then output quality is improved, but device performance deteriorates due to processor overload
Solution Approach 1:
The patent divides the communication system into two separate interfaces with distinct responsibilities. The first interface handles high-speed data retrieval from memory, while the second interface manages data transmission to the host. This segmentation ensures high output quality through reliable data transfer while maintaining device performance by distributing processing tasks across specialized components rather than overloading the main processor.
Solution Approach 2:
The control unit performs self-service by independently managing data buffering, formatting, and transmission protocols. It autonomously handles the coordination between memory unit and host unit, eliminating the need for the main processor to intervene in routine data transmission tasks. This self-service capability ensures high output quality while preserving overall device performance for other critical operations.
3Productivity
If single communication interface is used, then device complexity is reduced, but data throughput is limited
Solution Approach 1:
The patent implements segmentation by creating two specialized communication interfaces instead of one general-purpose interface. The first interface is optimized for high-speed data retrieval from the memory unit, while the second interface is optimized for data transmission to the host unit. This segmentation increases data throughput by allowing each interface to be optimized for its specific function, while the overall complexity is managed through the control unit's coordination logic.
Solution Approach 2:
The control unit serves multiple functions: it manages the first communication interface with the memory unit, manages the second communication interface with the host unit, performs data buffering, handles protocol conversion, and coordinates data flow between interfaces. This multi-functionality allows the system to achieve high data throughput through specialized interfaces while containing complexity within a single versatile control component.
Data Source
AI summary
A memory card and a communication method between a memory card and a host unit are disclosed. High throughput of data between the memory card and the host unit is guaranteed by providing a communication interface between the memory card and the host unit including a first communication interface between a memory unit of the memory card and a control unit of the memory card and a second communication interface between the control unit of the memory card and the host unit.
