Compiler-Based Transmission Scheduling for Crosstalk Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crosstalk between communication channels in computing systems causes data transmission errors, leading to increased latency and reduced throughput, which existing technologies have not adequately addressed.
Innovation Solution
A compiler determines the timing of data transmissions based on crosstalk data to mitigate interference by scheduling data transfers to avoid simultaneous transmissions on high-crosstalk pairs of channels, using proximity, signal strength, and transmission path length considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmissions are scheduled without considering crosstalk, then data transmission throughput is maximized, but data transmission errors increase due to crosstalk interference
Solution Approach 1:
The system performs preliminary analysis of crosstalk characteristics between communication channels before scheduling data transmissions. The compiler determines timing information for data transmissions in advance based on crosstalk data, preventing crosstalk-induced errors before they occur. This advance planning ensures reliable data transmission while maintaining high throughput by identifying and avoiding problematic transmission timings beforehand.
2Reliability
If data transmissions are scheduled to avoid crosstalk interference, then data transmission errors are reduced, but transmission latency increases due to timing adjustments
Solution Approach 1:
The system changes the timing parameters of data transmissions dynamically based on crosstalk characteristics. The compiler determines optimal timing information that avoids high-crosstalk periods while minimizing delays. By adjusting transmission timing parameters according to crosstalk data, the system reduces errors without incurring excessive latency penalties.
3Reliability
If crosstalk mitigation scheduling is implemented, then retransmission rates decrease, but system complexity increases due to compile-time analysis requirements
Solution Approach 1:
The compiler performs crosstalk analysis and determines timing information in advance during the compilation phase. By completing the complex analysis work beforehand, the runtime system only needs to execute pre-determined timing schedules, significantly reducing runtime overhead and complexity. This shift of computational burden to compile time enables effective crosstalk mitigation without excessive runtime system complexity.

Function Achieved in This Case
This approach reduces crosstalk-related errors, lowers retransmission rates, and decreases communication costs by optimizing data transmission schedules to minimize interference.
Implementation Method 1
Crosstalk is a phenomenon wherein a first signal transmitted via a first circuit or first communication channel may have an undesired effect on a second circuit or second communication channel. For example, in some instances, an electromagnetic field generated by a transmitting channel can induce a voltage in an adjacent channel, thereby causing interference
Data Source
AI summary
An example method can include determining, by a compiler based at least in part on crosstalk data indicative of a rate of crosstalk between a first data transmission path and a second data transmission path, a timing of a first data transmission over the first data transmission path. The example method can include providing, by the compiler, one or more computer-readable instructions to cause one or more processor devices to initiate the first data transmission according to the timing.
