Communication Processing Device Segment Addressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with limited memory in the communication processing device, the range of data that can be read out from the data management device is restricted, limiting the type of addresses that can be specified in readout requests and the corresponding memory regions that can be accessed.
Innovation Solution
A communication processing device that includes an antenna for signal transmission and a control unit capable of receiving an address update request signal with a segment identifier, allowing it to hold the segment identifier and transmit data from a region specified by an offset address relative to the segment address, enabling data access from a wider range of memory regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the memory of the communication processing device is small, then the device complexity is reduced, but the range of data that can be read out from the data management device is limited
Solution Approach 1:
The patent divides the data management device memory into multiple segments, each identified by a segment identifier. The communication processing device reads data by specifying a segment identifier and an offset address within that segment, allowing access to different memory regions without requiring large buffer memory. This segmentation enables the system to read out data from a wider range of memory regions despite limited communication processing device memory.
2Volume of stationary object
If the memory of the communication processing device is small, then the device complexity is reduced, but the type of address that can be specified in the readout request is few
Solution Approach 1:
The patent introduces a two-dimensional addressing scheme consisting of a segment identifier (selecting the memory segment) and an offset address (selecting the position within the segment). This dimensional expansion allows the system to specify a much larger address space than would be possible with a single address field, enabling diverse address specification capabilities while keeping the communication processing device memory small.

AI summary
A communication processing device includes a control unit for, when receiving an address update request signal including a segment identifier for identifying a segment address of a recording unit from a reader/writer, holding the segment identifier in a RAM, and when receiving a readout request signal including an offset address having the segment as a reference from the reader/writer, transmitting to the reader/writer data recorded in a region specified by an address having the offset address contained in the readout request signal as offset with the segment address identified in the segment identifier as a reference of the regions of the recording unit.
