Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current trace data transmission methods waste bandwidth due to excessive transmission of source identification data, which is not essential for the utilization device, leading to inefficient data stream utilization.

Innovation Solution

Implementing a system where trace data is transmitted in bursts, minimizing source identification transmission by using a logic circuit that generates a ready signal only when a source has a burst or minimum threshold of data available for transfer, thereby optimizing bandwidth utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If source identification data is transmitted before each data block, then the utilization device can properly use the data, but the bandwidth utilization decreases due to excessive transmission of non-essential identification data

Engineering Contradiction:

Improvedata usabilityVSAvoidbandwidth utilization

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts and removes the source identification data from the transmission stream, relying on the utilization device to infer the source from contextual information rather than receiving explicit identification blocks. This eliminates the bandwidth waste while preserving data usability through implicit source identification.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a simplified representation of source identification by copying only essential contextual information from the data stream itself, rather than transmitting full source identification blocks. This allows the utilization device to determine the source from the data context without additional overhead.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If data is transmitted in smaller increments, then the transmission flexibility increases, but the bandwidth utilization decreases due to more frequent source identification blocks

Engineering Contradiction:

Improvetransmission flexibilityVSAvoidbandwidth utilization

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements periodic action by transmitting source identification data only at specific intervals or under certain conditions rather than before every data block. This reduces the frequency of identification transmission while maintaining transmission flexibility through conditional triggering mechanisms.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the source identification transmission adaptive based on the data stream characteristics. The system dynamically determines when source identification is necessary versus when it can be inferred, optimizing the balance between flexibility and bandwidth utilization.

Inventive Principle:

Principle #15Dynamics

AI summary

This invention controls data transmission from a data source to a sink. The data source buffers the data. The data source signaling to transmit data upon storing a burst amount of data. The data source may include a plurality of data sources. A merge unit merges data by receiving and retransmitting data from each data source which signals to transmit and inserting a source identity block each time the merged data is received from a different source.
