Network Slave-Circuit Broadcast Access for Accurate Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network apparatuses, simultaneous data writing or reading on multiple physical layer circuits leads to data transmission conflicts and errors due to the absence of a proper communication mechanism.
Innovation Solution
A network apparatus with a slave circuit broadcast accessing mechanism, where each lower layer slave circuit has a unique device address, and an upper layer master circuit configures them into a broadcast mode to perform data writing and reading, ensuring only one slave circuit with a matching address performs data reading or writing based on a broadcast address.

Engineering Contradiction Analysis
1Productivity
If the media access control circuit performs data writing or reading simultaneously on multiple physical layer circuits, then the communication efficiency is improved, but data transmission conflicts occur causing errors
Solution Approach 1:
The patent segments the slave circuits into two functional groups: those configured for broadcast mode (receiving commands) and those configured for individual address mode (responding to commands). This segmentation allows simultaneous operations without conflict by separating the roles of different slave circuits based on their address configuration
Solution Approach 2:
The patent applies local quality by configuring different slave circuits with different operational characteristics based on their addresses. Slave circuits with broadcast addresses operate differently from those with individual addresses, allowing each to perform its specific function optimally without interfering with others
2Productivity
If a broadcast mode is implemented to allow simultaneous data writing on all slave circuits, then the data writing efficiency is improved, but false data reading results occur when multiple slave circuits respond simultaneously
Solution Approach 1:
The patent segments slave circuits into broadcast-mode circuits (for writing) and individual-address circuits (for reading). This segmentation ensures that when a read command is sent, only circuits with matching individual addresses respond, preventing false reading results while maintaining efficient broadcast writing capability
Solution Approach 2:
The patent configures different local qualities for different slave circuits based on their addresses. Circuits with broadcast addresses are optimized for receiving write commands, while circuits with individual addresses are optimized for responding to read commands, ensuring accurate data reading without false positives

AI summary
The present invention discloses a network apparatus having slave circuit broadcast accessing mechanism. Each of lower layer slave circuits has an independent device address. An upper layer master circuit transmits a broadcast mode activation command including a broadcast address to lower layer slave circuits to configure the lower layer slave circuits with the broadcast address to enter a broadcast mode, transmit a broadcast mode write command including the broadcast address and broadcast write data to the lower layer slave circuits such that the lower layer slave circuits configured to have the broadcast address perform data writing according to the broadcast write data and transmit a broadcast mode read command including the broadcast address to the lower layer slave circuits to request one of the lower layer slave circuits having a device address being the same as the broadcast address to perform data reading and return individual read data.
