NFC Memory Architecture for Direct ASCII Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near-field communication devices face inefficiencies in storing and transmitting messages due to the need for conversion between binary and ASCII formats, which increases memory space requirements and causes delays in message transmission.
Innovation Solution
A near-field communication device is designed with a memory structure that separates message components into static and dynamic portions, where the static portion is stored in a free access area in ASCII format and the dynamic portion is stored in a restricted access area, allowing for direct transmission in ASCII format without the need for conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If messages are stored in binary format for efficient memory usage, then memory space requirements are reduced, but conversion delays and processing complexity increase during transmission
Solution Approach 1:
The memory is divided into two distinct portions: a first portion for storing the variable portion of the message in ASCII format, and a second portion for storing data in hexadecimal language. This segmentation allows the system to maintain both ASCII and hexadecimal storage capabilities simultaneously, eliminating the need for conversion during transmission while optimizing memory space utilization.
Solution Approach 2:
The message variable portion is pre-stored in ASCII format in the first portion of memory before transmission is needed. This preliminary action eliminates the need for real-time conversion during transmission, reducing conversion delays and processing time while maintaining efficient memory space requirements.
2Speed
If messages are stored in ASCII format for direct transmission, then transmission speed is improved, but memory space requirements increase
Solution Approach 1:
The memory is segmented into a first portion for ASCII format variable message data and a second portion for hexadecimal language data. This allows the system to store ASCII formatted messages for direct transmission while using hexadecimal storage for other data, optimizing both transmission speed and memory space utilization through selective formatting.
Solution Approach 2:
The system changes the storage parameter of the variable message portion to ASCII format specifically for transmission purposes, while maintaining hexadecimal format for other data storage. This parameter change allows direct transmission without conversion while managing memory space efficiently through format selection.
3Adaptability or versatility
If conversion between binary and ASCII formats is performed, then data compatibility is improved, but processing complexity and power consumption increase
Solution Approach 1:
The memory is divided into portions for different data formats (ASCII and hexadecimal), allowing the system to maintain data compatibility by storing messages in the appropriate format from the outset. This eliminates the need for complex conversion processing while maintaining versatility in data handling.
Solution Approach 2:
Data is pre-formatted in ASCII or hexadecimal language according to the transmission requirements before the transmission process begins. This preliminary action eliminates the need for complex real-time conversion processing, reducing device complexity and power consumption while maintaining data compatibility.
4Adaptability or versatility
If conversion steps are included in the transmission process, then data format flexibility is improved, but power consumption increases
Solution Approach 1:
The memory is segmented to store different data formats (ASCII and hexadecimal) in separate portions, allowing the system to maintain data format flexibility by selecting the appropriate pre-formatted data for transmission. This eliminates the need for energy-intensive real-time conversion operations.
Solution Approach 2:
Data is pre-formatted in the required ASCII or hexadecimal language before transmission is needed. This preliminary action maintains data format flexibility while eliminating the need for power-consuming real-time conversion steps during transmission.
